1
00:00:00.000 --> 00:00:07.500
on the 3d side we are going to look at the idea of dual external rotation where
2
00:00:07.500 --> 00:00:13.920
basically the discussing the look of golfers you tend to get more kind of
3
00:00:13.920 --> 00:00:19.500
knees spread apart the same squat same steam squat versus golfers you tend to
4
00:00:19.500 --> 00:00:23.760
have a little bit more of a movement where everything kind of drifts so we're
5
00:00:23.760 --> 00:00:28.920
gonna look at that as it relates to 3d graphs get hopefully a clearer idea of
6
00:00:28.920 --> 00:00:35.280
what's going on there anatomy we're going to take a look at some basic knee
7
00:00:35.280 --> 00:00:40.280
anatomy so not the super advanced fascia stuff but we'll look at the joint and
8
00:00:40.280 --> 00:00:47.640
the muscles and the implications for golf and we'll briefly discuss if you're
9
00:00:47.640 --> 00:00:52.040
working with a client who has a knee replacement what are some possible things
10
00:00:52.040 --> 00:00:58.080
that you have to consider and then we've got of just a couple questions and we
11
00:00:58.080 --> 00:00:58.080
've
12
00:00:58.080 --> 00:01:06.520
got a few swings to take a look at so shouldn't be a terribly long call unless
13
00:01:06.520 --> 00:01:13.120
there's a whole bunch of live questions but let's get into the fun topic here
14
00:01:13.120 --> 00:01:14.640
so
15
00:01:14.640 --> 00:01:24.920
let me switch that over all right so what will I've got five different pro
16
00:01:24.920 --> 00:01:25.320
swings
17
00:01:25.320 --> 00:01:30.280
and then two different amateur swings and for the pro swings I wanted you to be
18
00:01:30.280 --> 00:01:37.440
able to visualize it so I'm gonna let the five swings kind of play through so
19
00:01:37.440 --> 00:01:43.440
you'll see it switch over try not to guess or type in the chat if you think
20
00:01:43.440 --> 00:01:49.760
you know who it is but I'll go kind of at regular speed and then a little bit
21
00:01:49.760 --> 00:01:55.320
of frame by frame there and we'll jump back and forth after we look at the
22
00:01:55.320 --> 00:02:02.520
graphs so this is one of the classic examples for looking at kind of dual
23
00:02:02.520 --> 00:02:12.240
external rotation right getting into that really wide Sam's the squat look and
24
00:02:12.240 --> 00:02:20.160
then we've got a couple others who are let's say more kind of in the middle and
25
00:02:20.160 --> 00:02:25.560
then we'll end with one more who has a really classic look of the dual
26
00:02:25.560 --> 00:02:32.800
external rotation but while we're going through this if you're if you're on go
27
00:02:32.800 --> 00:02:37.760
ahead and type in the in the chat just so I kind of have an idea of who's who's
28
00:02:37.760 --> 00:02:47.000
listening in where the questions might be coming from so here we have good and
29
00:02:47.000 --> 00:02:54.680
then this is the last golfer believe kind of has that classic look of the
30
00:02:54.680 --> 00:03:01.840
lead leg moving away from the trail leg in transition so there you can see
31
00:03:01.840 --> 00:03:06.040
lead leg doesn't look like it moves a whole lot trail leg moving away from it
32
00:03:06.040 --> 00:03:12.840
okay so now we're gonna go through each of these golfers and I'll I'll go back
33
00:03:12.840 --> 00:03:18.600
and and kind of play them in between looking at each cluster but I got a
34
00:03:18.600 --> 00:03:25.680
handful of graphs that we'll look at that all relate to this idea of the knee
35
00:03:25.680 --> 00:03:31.640
and the hip and the ankle creating that look of dual external rotation so I'll
36
00:03:31.640 --> 00:03:35.720
just go through the graphs first and then we'll we'll talk about each golfer
37
00:03:35.720 --> 00:03:36.680
kind
38
00:03:36.680 --> 00:03:42.680
of as a whole so I guess I'll start down here at the bottom so this is internal
39
00:03:42.680 --> 00:03:49.040
versus external hip rotation when the graph goes positive or up it's going
40
00:03:49.040 --> 00:03:53.760
into internal rotation and when it goes negative it's going into external
41
00:03:53.760 --> 00:04:00.640
rotation we'll see that this is even though it's described as an external
42
00:04:00.640 --> 00:04:06.480
rotation of the lead knee often we'll see that this is one of the least useful
43
00:04:06.480 --> 00:04:12.160
graphs for diagnosing that pattern okay so now if we jump up top here we've got
44
00:04:12.160 --> 00:04:21.280
hip ABduction ADduction so ABduction is if it's going negative which is the
45
00:04:21.280 --> 00:04:28.280
basically like doing the splits so the the hip is opening up and then AD
46
00:04:28.280 --> 00:04:32.560
ADduction is when the knees are coming closer together coming towards the
47
00:04:32.560 --> 00:04:37.840
midline and that's if it's going positive and we've got knee sway so
48
00:04:37.840 --> 00:04:42.200
basically looking at the horizontal displacement towards or away from the
49
00:04:42.200 --> 00:04:50.280
target as the golfer is going through the swing in all of these cases I believe
50
00:04:50.280 --> 00:04:56.600
the green line is the trail hip and the red line is the lead knee or hip I
51
00:04:56.600 --> 00:04:56.920
should
52
00:04:56.920 --> 00:05:02.410
say then we're looking at knee bend this is an interesting graph to look at we
53
00:05:02.410 --> 00:05:02.680
'll
54
00:05:02.680 --> 00:05:05.740
talk a little bit about this especially with one of the amateurs or actually
55
00:05:05.740 --> 00:05:12.920
both of the amateurs so looking at the trail knee as the green line possibly
56
00:05:12.920 --> 00:05:17.880
having a little bit of bend and then or sorry straightening a little bit when
57
00:05:17.880 --> 00:05:17.960
it
58
00:05:17.960 --> 00:05:23.240
goes negative it's straightening when it goes positive it is bending more so
59
00:05:23.240 --> 00:05:29.840
we'll address this pattern and then looking at hip flexion extension so
60
00:05:29.840 --> 00:05:35.440
you'll see usually an inverse pair in transition and then we'll talk about
61
00:05:35.440 --> 00:05:41.640
what happens a little bit in the downswing knee separation is when they talk
62
00:05:41.640 --> 00:05:47.320
about getting your hips or your knees away from each other knee separation
63
00:05:47.320 --> 00:05:47.480
would
64
00:05:47.480 --> 00:05:53.520
be the absolute measurement of the distance between your knees now it's in
65
00:05:53.520 --> 00:05:58.360
3d space so you could keep them the same distance apart but they would look
66
00:05:58.360 --> 00:05:58.560
like
67
00:05:58.560 --> 00:06:03.680
they increased from a face on camera view or vice versa but this is just
68
00:06:03.680 --> 00:06:09.920
looking at the actual 3d space between the knees and then the last graph graph
69
00:06:09.920 --> 00:06:14.720
is looking at the ankle and looking at the pronation supination so we covered
70
00:06:14.720 --> 00:06:20.640
that a little bit we covered the motion in last month's call but this month we
71
00:06:20.640 --> 00:06:20.680
're
72
00:06:20.680 --> 00:06:23.760
gonna look at the graph as it relates to this knee separation because it's
73
00:06:23.760 --> 00:06:29.520
actually one of the most important ones for looking at lead hip the look of
74
00:06:29.520 --> 00:06:29.880
dual
75
00:06:29.880 --> 00:06:39.440
external rotation okay so now let's let's jump through these again this is what
76
00:06:39.440 --> 00:06:47.320
we'll do for each golfer we'll let it play so here we go so this is the first
77
00:06:47.320 --> 00:06:54.400
example you'll see in transition it's kind of a little bit of you might call
78
00:06:54.400 --> 00:07:00.080
it a rotation you'll see the pelvis looks like it rotates into the thigh the
79
00:07:00.080 --> 00:07:03.680
trail knee comes with it a little bit and then it starts to get into a vertical
80
00:07:03.680 --> 00:07:14.000
movement okay so now here's that pattern so the the trail hip during the back
81
00:07:14.000 --> 00:07:14.200
swing
82
00:07:14.200 --> 00:07:20.560
is going to go into internal rotation and then briefly before the top of the
83
00:07:20.560 --> 00:07:24.320
swing it will start to go into external rotation that will continue all the way
84
00:07:24.320 --> 00:07:31.320
through impact the lead knee is going to go into external rotation during the
85
00:07:31.320 --> 00:07:36.520
backswing reaching close to its maximum range and then right around the same
86
00:07:36.520 --> 00:07:43.040
time as the pelvis changes direction the hip is going to go into or start
87
00:07:43.040 --> 00:07:47.120
working towards internal rotation doesn't actually reach internal rotation
88
00:07:47.120 --> 00:07:54.000
until after impact but it's moving internally what you'll see here is down
89
00:07:54.000 --> 00:07:57.880
near impact there'll be a blip where it goes external that's usually when the
90
00:07:57.880 --> 00:08:05.680
golfer's lead leg is off the ground and so the foot now is able to pivot
91
00:08:05.680 --> 00:08:13.360
without friction holding it back but you'll you'll see that once the pelvis
92
00:08:13.360 --> 00:08:21.120
starts to rotate towards the target you'll have to have this pattern of lead
93
00:08:21.120 --> 00:08:25.200
hip internal trail hip external especially because you're reaching near
94
00:08:25.200 --> 00:08:28.640
maximum range of motion with that lead hip as you approach the top of the
95
00:08:28.640 --> 00:08:33.760
backswing so what we'll see through the five graphs or the five pro examples is
96
00:08:33.760 --> 00:08:39.720
that this is one of the least indicative of the actual dual external rotation
97
00:08:39.720 --> 00:08:46.240
okay now if we look at abduction adduction this is another one that golfer's
98
00:08:46.240 --> 00:08:51.480
would commonly associate with the the look of dual external rotation if we look
99
00:08:51.480 --> 00:08:58.040
at the trail hip it's going to be adducting because basically the the pelvis
100
00:08:58.040 --> 00:09:01.760
is moving towards the leg and then during the downswing you're gonna see
101
00:09:01.760 --> 00:09:08.840
it abduct or move away we're gonna see basically the opposite pattern with a
102
00:09:08.840 --> 00:09:16.240
slight variation in the timing of when it goes from from abduction to adduction
103
00:09:16.240 --> 00:09:20.800
but you'll see that during pretty much the entire downswing that lead leg is
104
00:09:20.800 --> 00:09:26.800
going into a significant amount of adduction this one has some interesting
105
00:09:26.800 --> 00:09:31.620
characteristics but similar to internal external it's that it definitely doesn
106
00:09:31.620 --> 00:09:31.720
't
107
00:09:31.720 --> 00:09:39.720
tell a whole lot of the story if we jump down diagonally knee separation will
108
00:09:39.720 --> 00:09:44.480
give us a good estimate of that look so the golfers who have more of that squat
109
00:09:44.480 --> 00:09:49.640
look you will see an increase in the space between the knees now remember it's
110
00:09:49.640 --> 00:09:49.720
a
111
00:09:49.720 --> 00:09:55.960
3d space so some of that is coming from the rotation of the pelvis where if one
112
00:09:55.960 --> 00:10:01.920
leg stays in place and the other leg is following more of the rotation of the
113
00:10:01.920 --> 00:10:10.200
pelvis those will tend to in get further apart now the two most interesting for
114
00:10:10.200 --> 00:10:14.800
this pattern are actually looking at the knee bend and the ankle pronation
115
00:10:14.800 --> 00:10:24.720
supination so if we look at the lead knee or the lead leg I should say then
116
00:10:24.720 --> 00:10:25.240
what
117
00:10:25.240 --> 00:10:30.400
we'll see during the the backswing is that the lead foot is actually going to
118
00:10:30.400 --> 00:10:37.200
supinate slightly and then during transition it's going to pronate so I'll
119
00:10:37.200 --> 00:10:43.360
bring my camera real quick so when we're looking at the foot basically during
120
00:10:43.360 --> 00:10:43.760
the
121
00:10:43.760 --> 00:10:47.760
backswing it's actually supinating a little bit like this and then during the
122
00:10:47.760 --> 00:10:53.760
downswing this golfer is actually going to roll that foot in and it's pretty
123
00:10:53.760 --> 00:10:59.480
significant 10 15 degrees or so so if you if you can see my leg my left leg
124
00:10:59.480 --> 00:11:06.120
right here when I roll that foot in as my pelvis is going to turn that's gonna
125
00:11:06.120 --> 00:11:13.960
create the look of more internal rotation but that and that are pretty much the
126
00:11:13.960 --> 00:11:18.280
same I'm kind of holding this in place so that I have a good reference that's
127
00:11:18.280 --> 00:11:25.160
the same amount of internal rotation of the hip but I was moving my knee from
128
00:11:25.160 --> 00:11:25.400
the
129
00:11:25.400 --> 00:11:30.920
ankle going into pronation or supination what we'll see with the two golfers
130
00:11:30.920 --> 00:11:31.040
who
131
00:11:31.040 --> 00:11:37.640
have more of the pronounced external rotation look is that they're gonna go
132
00:11:37.640 --> 00:11:40.960
into supination of the trail foot where the golfers who have more of that
133
00:11:40.960 --> 00:11:48.840
internal rotation look go into pronation of that lead ankle so let's go back to
134
00:11:48.840 --> 00:11:53.800
where you can see my mouse okay so it's a really clear either this line is
135
00:11:53.800 --> 00:11:54.080
going
136
00:11:54.080 --> 00:11:59.040
down therefore it's pronating or it's going up therefore it's supinating
137
00:11:59.040 --> 00:12:06.400
trail ankle doesn't have as clear pattern but because it's very hard to
138
00:12:06.400 --> 00:12:13.280
supinate a ton when you're shifting your pelvis to the left but we'll focus
139
00:12:13.280 --> 00:12:17.700
primarily on the knee on the lead leg there and then we'll talk about knee
140
00:12:17.700 --> 00:12:24.120
bends they they have a little bit of an impact on the the look of internal
141
00:12:24.120 --> 00:12:27.440
external but they're just more of a good pattern to start understanding because
142
00:12:27.440 --> 00:12:32.200
this is where you'll see a fair amount of the difference between the pros and
143
00:12:32.200 --> 00:12:32.280
the
144
00:12:32.280 --> 00:12:40.290
amps so the normal pattern is straighten a little bit in the backswing bend we
145
00:12:40.290 --> 00:12:40.800
're
146
00:12:40.800 --> 00:12:44.640
looking at the trail knee straighten a bit in the backswing increase the flex
147
00:12:44.640 --> 00:12:49.360
past where it was to start in the early downswing and then straighten late and
148
00:12:49.360 --> 00:12:54.850
you'll see both legs and this particular golfer very close to straight when he
149
00:12:54.850 --> 00:12:54.880
's
150
00:12:54.880 --> 00:13:00.840
actually making contact with a golf ball okay so now we'll jump into the second
151
00:13:00.840 --> 00:13:13.600
one let's see how well we and the second one is one of the golfers who is
152
00:13:13.600 --> 00:13:24.120
classically used as an example of the dual external rotation so you'll see
153
00:13:24.120 --> 00:13:30.840
the space between the legs really increasing and they are definitely the
154
00:13:30.840 --> 00:13:35.640
space between the legs is definitely increasing okay so that was option number
155
00:13:35.640 --> 00:13:43.080
two here are option number two or pro number two's graph so if we look at
156
00:13:43.080 --> 00:13:47.160
internal versus external what you'll actually see is this golfer who looks
157
00:13:47.160 --> 00:13:52.880
like he's going into massive external rotation is actually going into internal
158
00:13:52.880 --> 00:14:00.480
rotation much earlier than the golfer who didn't have the same look so that's
159
00:14:00.480 --> 00:14:04.710
kind of one of the optical illusions if you're just looking at where the knee
160
00:14:04.710 --> 00:14:04.800
is
161
00:14:04.800 --> 00:14:11.800
pointing and using that as a reference as to what the the hip is doing if we
162
00:14:11.800 --> 00:14:20.040
look at abduction adduction you'll see even though it looks like that lead leg
163
00:14:20.040 --> 00:14:26.760
is pulling away and going into more abduction you can see that it's actually
164
00:14:26.760 --> 00:14:32.000
slightly moving towards adduction it's not moving at a great rate but it's
165
00:14:32.000 --> 00:14:39.880
moving towards adduction okay if we go over to the pronation supination graph
166
00:14:39.880 --> 00:14:45.200
when we look at the lead ankle so the red line you'll see that as he changes
167
00:14:45.200 --> 00:14:51.640
direction that lead leg or that lead ankle is going into almost 15 degrees of
168
00:14:51.640 --> 00:14:56.960
supination if I click back so you can compare you can see there's a big
169
00:14:56.960 --> 00:15:03.380
difference between the red line going down and the red line going up and they
170
00:15:03.380 --> 00:15:03.440
're
171
00:15:03.440 --> 00:15:07.800
going about the same amount the same magnitude but in totally opposite
172
00:15:07.800 --> 00:15:15.000
opposite directions so in one sense the that lead foot is driving where the
173
00:15:15.000 --> 00:15:15.160
knee
174
00:15:15.160 --> 00:15:21.600
is going more so than what this golfer is doing with the hip and you can also
175
00:15:21.600 --> 00:15:26.760
see that there is a difference between what's happening with the trail ankle so
176
00:15:26.760 --> 00:15:34.560
the golfer who is going more in into the less external direction that lead or
177
00:15:34.560 --> 00:15:40.360
sorry that trail ankle is going into supination where here it's going
178
00:15:40.360 --> 00:15:45.920
slightly into pronation or pretty much staying closer to the same it really
179
00:15:45.920 --> 00:15:50.160
doesn't start pronating until later in the downswing but the lead ankle going
180
00:15:50.160 --> 00:15:54.240
into supination is something that you'll classically see with the golfers who
181
00:15:54.240 --> 00:16:01.440
have that dual external rotation look more so than the hip ABA deduction or
182
00:16:01.440 --> 00:16:06.360
internal external rotation or flexion extension I'm not really even talking
183
00:16:06.360 --> 00:16:11.240
about flexion extension because it's a really minor part of this equation
184
00:16:11.240 --> 00:16:20.200
typically basically in order to rotate you would have to have one hip going
185
00:16:20.200 --> 00:16:26.680
into extension and one hip going into flexion so you'll typically see these
186
00:16:26.680 --> 00:16:30.800
two going together when or going in slightly opposite directions when it's
187
00:16:30.800 --> 00:16:35.960
rotating and then you'll see them both go into extension as they're applying
188
00:16:35.960 --> 00:16:36.320
more
189
00:16:36.320 --> 00:16:41.200
of the vertical force but this pattern this graph you'll see if I just quickly
190
00:16:41.200 --> 00:16:46.160
jump through all five of them you'll see the magnitudes are slightly different
191
00:16:46.160 --> 00:16:52.600
but the overall pattern is fairly consistent even with the higher handicap
192
00:16:52.600 --> 00:16:59.480
golfers you rarely see a huge deviation there okay so back to the important one
193
00:16:59.480 --> 00:17:07.080
of the you know looking at more of the knee separation the left leg looking
194
00:17:07.080 --> 00:17:07.240
like
195
00:17:07.240 --> 00:17:12.800
it goes into external rotation the other piece to look at is the knee bend
196
00:17:12.800 --> 00:17:19.480
here so you'll tend to see that part of what creates that separation look is
197
00:17:19.480 --> 00:17:21.040
the
198
00:17:21.040 --> 00:17:31.360
lead knee going into more of a extension position or starting to
199
00:17:31.360 --> 00:17:36.840
straighten as it's going into the change direction as the trail leg is
200
00:17:36.840 --> 00:17:41.720
bending more as opposed to with the golfer who had more of the internal
201
00:17:41.720 --> 00:17:47.080
rotation look you would see that the lead knee was actually bending more so
202
00:17:47.080 --> 00:17:52.160
getting an earlier straightening of that leg with the supination is going to
203
00:17:52.160 --> 00:17:52.400
create
204
00:17:52.400 --> 00:18:00.920
that giant squat look or the increase in the distance between the knees there's
205
00:18:00.920 --> 00:18:07.880
some other things going on in terms of rotation but these are the the core too
206
00:18:07.880 --> 00:18:21.520
okay so now if we jump to the third golfer so that's the second golfer we'll
207
00:18:21.520 --> 00:18:21.640
try
208
00:18:21.640 --> 00:18:25.560
to do a better job paying attention to the timestamp so I can jump right to it
209
00:18:25.560 --> 00:18:38.400
next time okay so he's at 41 all right so we'll watch this one this is a very
210
00:18:38.400 --> 00:18:42.400
good ball striker you'll see it's kind of got a little bit more of almost
211
00:18:42.400 --> 00:18:43.560
hybrid
212
00:18:43.560 --> 00:18:53.000
where it's it doesn't have a really big squat separation look but it also you
213
00:18:53.000 --> 00:18:57.440
know that might look like it's going in internal rotation by some but it doesn
214
00:18:57.440 --> 00:18:57.520
't
215
00:18:57.520 --> 00:19:02.440
look like the trail leg is coming along in the early stages it it comes along a
216
00:19:02.440 --> 00:19:09.480
little bit later okay okay so looking at that golfer we're gonna jump to his
217
00:19:09.480 --> 00:19:14.760
graphs and move a little bit quicker so we'll see again that usually when it
218
00:19:14.760 --> 00:19:20.480
looks like it's going into external rotation it's actually going into internal
219
00:19:20.480 --> 00:19:28.800
rotation quicker or earlier and then if we look at the ankle we saw again with
220
00:19:28.800 --> 00:19:33.800
the external rotation look it's gonna have more of going positive or supination
221
00:19:33.800 --> 00:19:39.600
the golfer is having more of the pronated look that's probably if you just
222
00:19:39.600 --> 00:19:45.640
needed one graph to look at that knee separation look other than looking at
223
00:19:45.640 --> 00:19:50.400
knee separation this would be the one that would tell you most clearly what
224
00:19:50.400 --> 00:19:53.800
their legs are gonna look like or what their knees are going to look like in
225
00:19:53.800 --> 00:20:03.480
transition now this golfer also you'll see has a fair amount of lead knee bend
226
00:20:03.480 --> 00:20:03.880
in
227
00:20:03.880 --> 00:20:08.200
transition and that typically keeps the knees closer together then if the lead
228
00:20:08.200 --> 00:20:18.020
knee starts to straighten earlier if we look at the abduction adduction this
229
00:20:18.020 --> 00:20:25.120
golfer is actually at abducting the leg so you would think that you would have
230
00:20:25.120 --> 00:20:30.960
more of a increase but because of what's happening at the ankle and what's
231
00:20:30.960 --> 00:20:36.600
happening at the flex in the trail knee those knees are staying closer together
232
00:20:36.600 --> 00:20:44.200
so it has more of that kind of less of the dual external rotation squat look
233
00:20:44.200 --> 00:20:45.200
that
234
00:20:45.200 --> 00:20:53.640
squat comes from straightening that lead knee supinating that lead foot and
235
00:20:53.640 --> 00:20:54.600
those
236
00:20:54.600 --> 00:20:59.080
are the the main two that you'll see more so than the adduction more so than
237
00:20:59.080 --> 00:21:09.680
that internal rotation so nothing else major to note here so we'll we'll move
238
00:21:09.680 --> 00:21:16.720
on the one of the interesting things about we're gonna come after we go
239
00:21:16.720 --> 00:21:20.160
through the pros we'll compare the amateurs and you'll see that while the
240
00:21:20.160 --> 00:21:25.280
knees have some interesting looks in the backswing that trail knee almost
241
00:21:25.280 --> 00:21:25.880
always
242
00:21:25.880 --> 00:21:33.240
is around 15 to 20 degrees closer to 15 degrees at the top of the swing there
243
00:21:33.240 --> 00:21:39.720
there are some outliers but we're gonna talk about why that 15 degree bend in
244
00:21:39.720 --> 00:21:43.400
the knee is important at the top of the swing that's gonna be one of your big
245
00:21:43.400 --> 00:21:49.680
takeaways to start paying attention to when you're looking at your students leg
246
00:21:49.680 --> 00:22:06.480
action okay so we'll move on to the fourth one what's right about here okay
247
00:22:06.480 --> 00:22:13.680
so this golfer is kind of more in the middle all right so if I go back and
248
00:22:13.680 --> 00:22:24.440
replay that so this golfer here is not really a massive squat look it but it's
249
00:22:24.440 --> 00:22:28.960
not really a massive internal rotation look either all right that'll be the
250
00:22:28.960 --> 00:22:40.120
last one we'll look at there okay so if we go to this second to last one you'll
251
00:22:40.120 --> 00:22:45.400
see when the knee graph is fairly flat they got a little bit further away from
252
00:22:45.400 --> 00:22:53.000
each other and you'll see if you look at the lead ankle through transition it's
253
00:22:53.000 --> 00:23:00.960
fairly flat it's neither going massively positive or massively negative like we
254
00:23:00.960 --> 00:23:07.360
saw with the two examples of kind of the internal versus external rotation look
255
00:23:07.360 --> 00:23:12.640
so when it's flatter like that it's gonna tend to have more of the look of
256
00:23:12.640 --> 00:23:18.680
neither it's kind of in the hybrid zone but you'll see if we look at the two
257
00:23:18.680 --> 00:23:18.840
that
258
00:23:18.840 --> 00:23:23.960
are classically associated with it internal external rotation pretty much
259
00:23:23.960 --> 00:23:29.920
has the same pattern that we were seeing with the other two ABduction ADX
260
00:23:29.920 --> 00:23:38.080
you're gonna see again pretty much that mere pattern similar to what you'll see
261
00:23:38.080 --> 00:23:44.400
with internal external rotation it's just really hard to have functional pelvis
262
00:23:44.400 --> 00:23:48.760
movement and deviate too much from that pattern but you can have pretty big
263
00:23:48.760 --> 00:23:51.520
differences in what's going on with the ankles and you can have pretty big
264
00:23:51.520 --> 00:23:56.160
differences as far as what's going on with the knees you'll see that this gol
265
00:23:56.160 --> 00:23:56.320
fer
266
00:23:56.320 --> 00:24:01.040
has a interesting quirk where the trail knee stays close to the same amount of
267
00:24:01.040 --> 00:24:07.480
flex during the entire swing a little bit of straightening in the backswing but
268
00:24:07.480 --> 00:24:13.120
relatively smaller piece and valleys compared to all the other ones that we
269
00:24:13.120 --> 00:24:18.960
were looking at but you will see in that 15 to 20 degree range at the top of
270
00:24:18.960 --> 00:24:18.960
the
271
00:24:18.960 --> 00:24:24.120
swing that is one of the I'd say my big takeaways when you're looking at the
272
00:24:24.120 --> 00:24:30.520
trail leg and it's well when we get in the anatomy we'll talk about it but it's
273
00:24:30.520 --> 00:24:37.400
critical for activation okay and then he has a little bit more of the knee
274
00:24:37.400 --> 00:24:38.360
bending
275
00:24:38.360 --> 00:24:42.160
in transition before straightening but pretty pronounced straightening during
276
00:24:42.160 --> 00:24:47.600
the noun swing again not nothing too crazy there let's look at the last
277
00:24:47.600 --> 00:25:00.280
example who's got more of a strong dual external rotation look so there's a
278
00:25:00.280 --> 00:25:06.280
little bit more of a strong dual external rotation look you'll see as he's
279
00:25:06.280 --> 00:25:11.680
changing direction space between the knees is getting wider it looks like the
280
00:25:11.680 --> 00:25:16.240
knee would be pointing kind of out this way towards the camera but so it would
281
00:25:16.240 --> 00:25:19.520
look like it was going into external rotation but we know that that's not
282
00:25:19.520 --> 00:25:24.720
gonna be the case when we look at the relationship between the pelvis and the
283
00:25:24.720 --> 00:25:31.600
thigh so if you if you look at it again when you're really zoomed in like this
284
00:25:31.600 --> 00:25:36.400
you will see that the pelvis is winning the race and catching up with the thigh
285
00:25:36.400 --> 00:25:41.520
and that's pretty much what you'll see if you learn to train your eyes to see
286
00:25:41.520 --> 00:25:41.640
it
287
00:25:41.640 --> 00:25:48.400
on video as well so here's the internal external rotation that lead leg is
288
00:25:48.400 --> 00:25:48.800
going
289
00:25:48.800 --> 00:25:55.160
into internal rotation even though the knee is pointing more outward and then
290
00:25:55.160 --> 00:25:58.560
you'll see because he comes off the ground he has a fair amount of this
291
00:25:58.560 --> 00:26:04.400
little secondary dip or going into external down through impact that's where
292
00:26:04.400 --> 00:26:08.960
the foot is come off the ground so the foot is actually turning out or pivoting
293
00:26:08.960 --> 00:26:16.640
outward so the leg is going into more external rotation there and he's got a
294
00:26:16.640 --> 00:26:26.360
little bit later transition from abduction to adduction but it's still
295
00:26:26.360 --> 00:26:31.400
right around top of the swing so you can see that the knee separation is
296
00:26:31.400 --> 00:26:35.040
happening for a good amount during the downswing much further than we're seeing
297
00:26:35.040 --> 00:26:42.720
just that abduction versus adduction so we wouldn't be able to a trap a tribute
298
00:26:42.720 --> 00:26:49.720
the difference in the knee to what's going on with that lead hip but if we
299
00:26:49.720 --> 00:26:54.320
look at the ankles you'll see right around top of the swing now he's going
300
00:26:54.320 --> 00:27:02.280
into a little less than the second golfer but he's going into the supination
301
00:27:02.280 --> 00:27:08.480
pattern that's going to have a big impact in pulling the knee away and then he
302
00:27:08.480 --> 00:27:08.680
has
303
00:27:08.680 --> 00:27:13.560
again he's right around that 15 degree mark at the top of the swing and then
304
00:27:13.560 --> 00:27:17.120
flexes both knees with kind of that unweighting move before a pretty
305
00:27:17.120 --> 00:27:25.400
powerful straightening of both of the legs okay so I didn't get the video of
306
00:27:25.400 --> 00:27:32.880
the amateurs but now you'll you'll see this is a higher handicap kind of
307
00:27:32.880 --> 00:27:38.980
slicer and you'll see it's only with the high handicappers that you'll tend to
308
00:27:38.980 --> 00:27:44.680
see the possibility of the lead hip going more external and that's because
309
00:27:44.680 --> 00:27:49.080
typically with the high handicappers or occasionally with the high handicappers
310
00:27:49.080 --> 00:27:54.320
the club is changing direction before the pelvis but if you compared this to
311
00:27:54.320 --> 00:27:59.880
when the pelvis actually changes direction it's always gonna line up now
312
00:27:59.880 --> 00:28:07.360
if we look at the ankle you'll you'll tend to see he's he's got that squat
313
00:28:07.360 --> 00:28:13.240
look he's kind of looks like a you're all demonstrated real quick so he would
314
00:28:13.240 --> 00:28:18.000
look kind of more like a like a throw over the top that way so he does get a
315
00:28:18.000 --> 00:28:21.800
little bit of the widening of the shoulders but he tends to get really
316
00:28:21.800 --> 00:28:27.140
over the over the top and then have to throw the more interesting thing is if
317
00:28:27.140 --> 00:28:32.800
you look at the knee bends you'll see the trail knee is increasing flex
318
00:28:32.800 --> 00:28:33.480
increasing
319
00:28:33.480 --> 00:28:38.520
flex increasing flex increasing flex he's basically just bending and digging
320
00:28:38.520 --> 00:28:42.640
that foot into the ground and then spinning like crazy there's a lot less
321
00:28:42.640 --> 00:28:47.440
of the vertical action that we saw in more the classic pattern and you'll see
322
00:28:47.440 --> 00:28:53.880
he's got his leg bent 25 degrees at the top of the swing or maybe even more
323
00:28:53.880 --> 00:28:54.800
that's
324
00:28:54.800 --> 00:29:00.520
more than needed and we'll talk about why some golfers might have more knee
325
00:29:00.520 --> 00:29:00.800
bend
326
00:29:00.800 --> 00:29:07.800
at the top of swing than less but these two graphs especially the knee bend are
327
00:29:07.800 --> 00:29:12.680
probably more relevant at looking at lower body action than looking at either
328
00:29:12.680 --> 00:29:18.360
the hip internal external or abduction adduction and that was one of the big
329
00:29:18.360 --> 00:29:25.800
takeaways that I wanted you to take away from this 3d section now here's the
330
00:29:25.800 --> 00:29:31.800
here's another high handicap this is a golfer who gets more hooks and if we
331
00:29:31.800 --> 00:29:37.720
jump over to the knee bend graph you'll see this golfer is well below so this
332
00:29:37.720 --> 00:29:37.880
is
333
00:29:37.880 --> 00:29:40.920
a golfer who looks like he pretty much locks his leg almost looks like a
334
00:29:40.920 --> 00:29:46.400
reverse pivot at the top of the swing so I know that some golf instructors talk
335
00:29:46.400 --> 00:29:53.690
about straightening the leg as much as possible you'll see even on the the golf
336
00:29:53.690 --> 00:29:53.880
ers
337
00:29:53.880 --> 00:30:00.080
the pro golfers who straighten the leg during the backswing it will regain some
338
00:30:00.080 --> 00:30:08.520
of that flex at the top of the swing in order to use the glute properly and you
339
00:30:08.520 --> 00:30:08.600
'll
340
00:30:08.600 --> 00:30:15.080
see why when we look at the anatomy but basically in order to have the maximum
341
00:30:15.080 --> 00:30:20.280
tension through the fascia around the glute you need about 15 degrees of bend
342
00:30:20.280 --> 00:30:24.920
of the knee so neither of these two golfers are really using their their
343
00:30:24.920 --> 00:30:29.440
glutes they're tending to either use more of their back and their shoulders in
344
00:30:29.440 --> 00:30:34.960
this case or in this case he's tending to use more of his quad and his knee so
345
00:30:34.960 --> 00:30:39.760
this graph over here on the right is is quite important unfortunately I don't
346
00:30:39.760 --> 00:30:45.840
have a ton of the amateur examples because I don't have a 12 sensor I only
347
00:30:45.840 --> 00:30:51.120
have the eight but that's a very interesting graph if you as we get more
348
00:30:51.120 --> 00:30:56.680
sensor technology or if you have access to a 12 sensor or total body that one's
349
00:30:56.680 --> 00:31:04.840
pretty interesting now I've seen through through R3D on AMM I've seen an an
350
00:31:04.840 --> 00:31:12.120
average of about the trail leg straightening about eight degrees I know that I
351
00:31:12.120 --> 00:31:19.680
saw someone with gears talking about them seeing it increase three degrees and
352
00:31:19.680 --> 00:31:24.600
that could be just the difference in terms of the measurement systems I tend
353
00:31:24.600 --> 00:31:30.760
to for the body I tend to trust the electromagnetic that we use versus the
354
00:31:30.760 --> 00:31:37.520
the gears or or matter something like that but just because it's measurement
355
00:31:37.520 --> 00:31:44.520
versus projected angles I think it's a little bit more accurate but the big
356
00:31:44.520 --> 00:31:44.920
takeaway
357
00:31:44.920 --> 00:31:52.800
is if you want that look of dual external rotation then we need to get the lead
358
00:31:52.800 --> 00:31:58.120
foot to supinate in transition not pronate that will encourage some of the
359
00:31:58.120 --> 00:32:06.240
pelvis rotation without having too much of the slide but I wanted to include
360
00:32:06.240 --> 00:32:06.440
the
361
00:32:06.440 --> 00:32:09.840
knee bend graph so that we would have a smooth transition into what we're gonna
362
00:32:09.840 --> 00:32:19.680
cover next which is the anatomy okay the knee is classically described as a
363
00:32:19.680 --> 00:32:25.040
simple hinge there are but we're gonna talk about why that's maybe not the
364
00:32:25.040 --> 00:32:31.160
best description so there are three main there are three bones that make up the
365
00:32:31.160 --> 00:32:35.840
knee you've got the femur the patella or the kneecap and then the tibia or the
366
00:32:35.840 --> 00:32:42.120
shin the the shin or the lower limb also includes the fibula but that does not
367
00:32:42.120 --> 00:32:47.880
that's usually not considered part of the knee that's usually more of the ankle
368
00:32:47.880 --> 00:32:55.800
so these three bones right here now there's a bunch of muscles and we're not
369
00:32:55.800 --> 00:33:01.920
gonna cover all of them because that would be pretty hard to do and it it you
370
00:33:01.920 --> 00:33:07.200
it's probably better to just think about like okay if this is my if this is my
371
00:33:07.200 --> 00:33:13.150
thigh you almost want to divide it into four four sections so you've got kind
372
00:33:13.150 --> 00:33:13.240
of
373
00:33:13.240 --> 00:33:18.120
a top side these are your quads on the outside you have a couple smaller
374
00:33:18.120 --> 00:33:18.560
muscles
375
00:33:18.560 --> 00:33:25.600
but one really big tight band your your it band or your tractus ileo tibialis
376
00:33:25.600 --> 00:33:31.720
and then on the inside you've got your adductors these are quite important for
377
00:33:31.720 --> 00:33:37.440
golf and then on the backside here you've got your hamstring group so you've
378
00:33:37.440 --> 00:33:37.680
got
379
00:33:37.680 --> 00:33:44.560
six quads and five hamster or five sorry adductors three hamstrings and then a
380
00:33:44.560 --> 00:33:53.120
couple muscles on the side of the leg but the reason we say it's not just a
381
00:33:53.120 --> 00:33:59.160
hinge joint is the the human knee actually has all six degrees of movement now
382
00:33:59.160 --> 00:34:04.920
it tends to have very limited amount of the slide those are more micro
383
00:34:04.920 --> 00:34:05.840
movements
384
00:34:05.840 --> 00:34:13.320
but it does have a fair amount of rotation in each direction so you can
385
00:34:13.320 --> 00:34:19.960
get the the knee flexion extension going this way it just broke his leg you can
386
00:34:19.960 --> 00:34:24.880
get rotation which we'll talk about and then you can get if we're looking at it
387
00:34:24.880 --> 00:34:31.640
face-on valgus or raris or tilt and those are those are the really the
388
00:34:31.640 --> 00:34:35.920
important movement so it looks more like this you've got your flexion extension
389
00:34:35.920 --> 00:34:40.820
moving in this direction you've got valgus and varis so the leg could either
390
00:34:40.820 --> 00:34:47.120
cave in dive in or it could bow outward and then you've got rotation of the
391
00:34:47.120 --> 00:34:47.440
thigh
392
00:34:47.440 --> 00:34:53.560
and rotation of the lower limb knee rotation is the rotation of the foot or
393
00:34:53.560 --> 00:34:59.200
the lower limb compared to the upper limb so usually if the femur was fixed
394
00:34:59.200 --> 00:35:07.000
where does the foot then point okay muscle wise you've got a handful of
395
00:35:07.000 --> 00:35:14.360
muscles that bend the knee mostly your quads or sorry that mostly your
396
00:35:14.360 --> 00:35:14.720
hamstring
397
00:35:14.720 --> 00:35:19.880
group and then the extension of the knee or straightening the knee is more of
398
00:35:19.880 --> 00:35:25.880
your quad activity and then you've got medial lateral rotation this particular
399
00:35:25.880 --> 00:35:31.680
slide doesn't talk about the valgus varis but basically if we go back to this
400
00:35:31.680 --> 00:35:38.640
slide the ones that pull the knee more into valgus would be the inside of the
401
00:35:38.640 --> 00:35:45.680
thigh or the adductors and the ones that pull it into sorry that pull it into
402
00:35:45.680 --> 00:35:49.720
valgus would be the outside of the leg which would pull the knee inward or the
403
00:35:49.720 --> 00:35:57.320
one that pulls it into varis would be more the inside of the leg now as a golf
404
00:35:57.320 --> 00:36:02.520
instructor you don't have to know the detailed anatomy but it's good to be
405
00:36:02.520 --> 00:36:07.360
able to understand when a golfer talks to you about either having an MCL issue
406
00:36:07.360 --> 00:36:13.440
or having a meniscus surgery this is this is what they're talking about so
407
00:36:13.440 --> 00:36:18.520
you've got your the patella has been removed so it's easier to see or actually
408
00:36:18.520 --> 00:36:24.760
we're looking at it from the yeah the front side of the right knee because of
409
00:36:24.760 --> 00:36:32.880
where the fibio's so the meniscus are these two little kind of horseshoe shaped
410
00:36:32.880 --> 00:36:39.280
cartilage enclosures and what they do if you look from the top down they're
411
00:36:39.280 --> 00:36:46.800
almost like like extra cushioning and so when you're when you're the ball of
412
00:36:46.800 --> 00:36:47.080
the
413
00:36:47.080 --> 00:36:51.080
femur is sitting in there they kind of cup it so then if I start to push on the
414
00:36:51.080 --> 00:36:55.640
side instead of having nothing to stop me from sliding there's a little bit of
415
00:36:55.640 --> 00:37:00.880
an edge there that edge when I push down into it increases the surface area so
416
00:37:00.880 --> 00:37:07.520
then I don't create quite as much stress on one particular area but when your
417
00:37:07.520 --> 00:37:12.680
golfer is talking about either I had a medial meniscus tear that would be this
418
00:37:12.680 --> 00:37:17.480
half over here or a lateral meniscus tear that would be over here and then
419
00:37:17.480 --> 00:37:21.240
anterior would be towards the front of the body or posterior would be towards
420
00:37:21.240 --> 00:37:25.520
the back of the body and typically what'll happen is the movement opposite to
421
00:37:25.520 --> 00:37:31.630
where the terrors will cause pain so when when we're looking at it like this
422
00:37:31.630 --> 00:37:32.600
you
423
00:37:32.600 --> 00:37:38.640
can imagine if the if the thigh was to say was gonna push towards the front or
424
00:37:38.640 --> 00:37:43.960
towards the camera this way then it would increase the pressure in this
425
00:37:43.960 --> 00:37:50.040
cartilage entrapment in the backside and vice versa so it's almost like a disc
426
00:37:50.040 --> 00:37:56.510
where it when you push one direction the pressure builds up on the other side
427
00:37:56.510 --> 00:37:57.600
now
428
00:37:57.600 --> 00:38:03.040
so that's the meniscus the other key component to the knee is looking at these
429
00:38:03.040 --> 00:38:07.800
ligaments and they basically act like like string or plastic that hold it
430
00:38:07.800 --> 00:38:13.760
together so you could see if I was to bow the leg out like this then this side
431
00:38:13.760 --> 00:38:18.360
here this that would be connecting these two so where my thumbs are that would
432
00:38:18.360 --> 00:38:22.760
be placed under tension or stress and if I went this way between the pinky side
433
00:38:22.760 --> 00:38:27.880
would be placed under tension or stress so for most knee injuries if you can
434
00:38:27.880 --> 00:38:32.320
keep the knee more in neutral especially when you're pushing vertically pushing
435
00:38:32.320 --> 00:38:36.760
a lot of force through it it's going to tend to be better for the overall
436
00:38:36.760 --> 00:38:44.880
structure so here's another picture just kind of showing the little sponge
437
00:38:44.880 --> 00:38:45.840
those
438
00:38:45.840 --> 00:38:50.360
meniscus in between and then here you can get a little better view of the ACL
439
00:38:50.360 --> 00:38:59.520
and the the PCL so you've got the medial MCL and then the lateral and then the
440
00:38:59.520 --> 00:39:03.560
anterior and posterior cruciate ligament which means crosses and they
441
00:39:03.560 --> 00:39:08.240
basically kind of look like this so if you take your middle finger and cross
442
00:39:08.240 --> 00:39:14.360
it over your front finger and then you put that up against your knee so the ACL
443
00:39:14.360 --> 00:39:19.280
is on top it goes from the outside across this way and then the PCL goes
444
00:39:19.280 --> 00:39:24.560
more runs it a direction more towards the outside of the leg like that and
445
00:39:24.560 --> 00:39:32.080
basically when they get stressed that's when they can potentially tear or cause
446
00:39:32.080 --> 00:39:38.880
injuries so for example this is the test for assessing the ACL so the ACL
447
00:39:38.880 --> 00:39:45.160
coming across like this if I if I pull the bottom further away from the top
448
00:39:45.160 --> 00:39:50.440
that's gonna lengthen that ligament and so if that ligament is damaged I'll be
449
00:39:50.440 --> 00:39:57.040
able to pull this more than I should be able to so when your golfers have
450
00:39:57.040 --> 00:40:02.120
ligament issues they can tend to cause really sharp pains and they'll tend to
451
00:40:02.120 --> 00:40:06.840
kind of like come out of I don't want to say come out of nowhere but it's like
452
00:40:06.840 --> 00:40:10.280
everything's fine everything's fine and then oh man I heard a lot and then it
453
00:40:10.280 --> 00:40:18.000
either lingers or goes away but it kind of comes out of nowhere so the most
454
00:40:18.000 --> 00:40:23.600
important part of that we'll cover here in a section or in a second so how that
455
00:40:23.600 --> 00:40:30.640
applies to the golf swing in the golfers you're gonna be working with and how
456
00:40:30.640 --> 00:40:35.760
that relates to some of those three graphs that we looked at okay so now we
457
00:40:35.760 --> 00:40:42.000
get back to these core movements and looking at the relationship of these the
458
00:40:42.000 --> 00:40:48.000
cool thing about the knee is it's a good way of looking at the movement of a
459
00:40:48.000 --> 00:40:54.880
whole lower limb got a slide here coming up in a bit that will help tie that in
460
00:40:54.880 --> 00:40:59.440
together but there are related movements of what will happen at the hip and
461
00:40:59.440 --> 00:40:59.640
what
462
00:40:59.640 --> 00:41:04.200
will happen at the ankle and the knee in the middle if you see the movement
463
00:41:04.200 --> 00:41:04.440
going
464
00:41:04.440 --> 00:41:07.240
in one direction or the other that can kind of give you a sense of what's
465
00:41:07.240 --> 00:41:11.570
happening at either the ankle or the hip or help out with that but these are
466
00:41:11.570 --> 00:41:11.640
the
467
00:41:11.640 --> 00:41:17.080
classic movements flexion extension valgus verus or abduction
468
00:41:17.080 --> 00:41:25.720
adduction and then internal external rotation of the tibia now the cool thing
469
00:41:25.720 --> 00:41:33.000
about the knee this is part of the reason why so the knee is not a hinge in any
470
00:41:33.000 --> 00:41:38.560
sense of the way more you know your elbow is close to a hinge it pretty much
471
00:41:38.560 --> 00:41:43.800
moves exclusively in this direction the knee has rotation and the side bending
472
00:41:43.800 --> 00:41:50.200
and when it does hinge this slide here is the show that it's not actually like
473
00:41:50.200 --> 00:41:50.240
a
474
00:41:50.240 --> 00:41:54.640
hinge like this there's actually a sliding movement now one of the
475
00:41:54.640 --> 00:41:58.960
questions about the knee was what happens when you get a knee replacement
476
00:41:58.960 --> 00:42:06.760
typically that sliding movement goes away so the instead of it sliding as it
477
00:42:06.760 --> 00:42:13.560
pivots like this it will now just kind of become more of a hinge so while there
478
00:42:13.560 --> 00:42:18.360
aren't too many contraindications for golf some of the movement patterns can
479
00:42:18.360 --> 00:42:23.280
change a little bit and golfers might not feel quite as comfortable with it
480
00:42:23.280 --> 00:42:30.360
that's usually the bigger thing that you have to address looking at so this is
481
00:42:30.360 --> 00:42:35.480
the extension when it moves in the opposite direction so as the bone slides
482
00:42:35.480 --> 00:42:42.920
this way it rolls that way so as it slides posterior it rolls anterior or
483
00:42:42.920 --> 00:42:50.820
basically this is what's happening when the leg is going into extension now we
484
00:42:50.820 --> 00:42:57.040
made it look pretty simple when we looked at the bone but those two called
485
00:42:57.040 --> 00:43:02.320
condyles the the surface area for how the the knee bones fit together are not
486
00:43:02.320 --> 00:43:08.480
symmetrical so they're on a little bit of an angle and one of them is bigger
487
00:43:08.480 --> 00:43:14.000
than the other so this the joint is designed to kind of flex the knee pretty
488
00:43:14.000 --> 00:43:19.200
straight but imagine trying to drive a car straight if you had a car that had
489
00:43:19.200 --> 00:43:25.720
one small wheel and one big wheel so it kind of has to regulate these two the
490
00:43:25.720 --> 00:43:34.920
the rates that they turn and the the surface on the bottom is pretty flat but
491
00:43:34.920 --> 00:43:39.680
the surface or the axis of rotation as you see from this little truncated cone
492
00:43:39.680 --> 00:43:45.320
becomes a little bit of an angle so as a result you actually get a little bit
493
00:43:45.320 --> 00:43:45.440
of
494
00:43:45.440 --> 00:43:52.080
rotation with bending and straightening the leg classically when you straighten
495
00:43:52.080 --> 00:43:58.400
the leg in order to lock it out the foot will actually at the end the last 20
496
00:43:58.400 --> 00:44:03.360
degrees which in this position I can't actually get into when you lock out the
497
00:44:03.360 --> 00:44:08.040
leg it will go into external rotation and then when you flex the leg it will go
498
00:44:08.040 --> 00:44:14.440
into internal rotation so that's why when you see someone walking that foot
499
00:44:14.440 --> 00:44:15.520
will
500
00:44:15.520 --> 00:44:21.720
tend to swing out behind and out to the side just a little bit that's the
501
00:44:21.720 --> 00:44:23.120
natural
502
00:44:23.120 --> 00:44:28.880
internal rotation associated with flexion of the knee so the interesting
503
00:44:28.880 --> 00:44:32.840
thing is when the knee is more flexed it has more range of motion rotationally
504
00:44:32.840 --> 00:44:37.000
when you straighten it it tends to lock in place so that you don't have to use
505
00:44:37.000 --> 00:44:40.640
your muscles to hold yourself up if you're standing for a long period of time
506
00:44:40.640 --> 00:44:46.440
now where that comes in is if you were to totally straighten the leg you would
507
00:44:46.440 --> 00:44:53.110
lose a significant amount of rotation at the knee so I know some golf
508
00:44:53.110 --> 00:44:53.560
instructors
509
00:44:53.560 --> 00:44:58.560
advocate fully straightening the leg or trying to straighten the leg but there
510
00:44:58.560 --> 00:45:02.640
is a point where you get past that 20 degree mark and now you start to lose
511
00:45:02.640 --> 00:45:07.640
rotation it's rotation of the knee and not the hip or the pelvis but it's still
512
00:45:07.640 --> 00:45:11.920
losing rotation so you don't want to advocate straightening the leg past that
513
00:45:11.920 --> 00:45:19.200
15 20 degree mark the other piece we'll get to here in a second so this was a
514
00:45:19.200 --> 00:45:24.000
interesting slide I just thought you could kind of it would help you envision
515
00:45:24.000 --> 00:45:28.280
why the knee has its shape and look the way that it does it's almost like a
516
00:45:28.280 --> 00:45:33.440
column where instead of having two poles sitting on top like this you've got a
517
00:45:33.440 --> 00:45:38.240
much broader surface area so for a structure that has to actually support
518
00:45:38.240 --> 00:45:42.560
a fair amount of weight they made it wider at the connection point so that
519
00:45:42.560 --> 00:45:48.080
you have greater surface area and the the bone actually has these almost like
520
00:45:48.080 --> 00:45:53.800
rebar in concrete and those need to line up that's how force goes through in
521
00:45:53.800 --> 00:45:53.920
the
522
00:45:53.920 --> 00:46:00.800
most kind of economical way so if you if your knee is caved in or out or
523
00:46:00.800 --> 00:46:04.800
rotated those things don't line up and you start to get where and you start to
524
00:46:04.800 --> 00:46:13.200
get arthritis building up so that there's a couple different angles that are
525
00:46:13.200 --> 00:46:13.440
key
526
00:46:13.440 --> 00:46:20.160
to looking at the lower limb typically the hip will hopefully be on about a
527
00:46:20.160 --> 00:46:26.240
three degree angle but the axis of the knee whoops the axis will go pretty much
528
00:46:26.240 --> 00:46:30.160
through the second toe through the knee through the hip joint like that so you
529
00:46:30.160 --> 00:46:30.160
've
530
00:46:30.160 --> 00:46:35.840
got the angle of the tibia and then you've got the angle of the femur but the
531
00:46:35.840 --> 00:46:40.450
relationship that you really want to look at is the second toe to the knee to
532
00:46:40.450 --> 00:46:40.560
the
533
00:46:40.560 --> 00:46:45.640
hip so this would be a case of a kind of knock knee this would be bow leg in
534
00:46:45.640 --> 00:46:45.920
both
535
00:46:45.920 --> 00:46:53.280
cases you can see that that force is going to be either too much on the inside
536
00:46:53.280 --> 00:46:59.320
there or too much on the outside based on the position and the tension being a
537
00:46:59.320 --> 00:47:07.680
little bit off so this is probably the most important slide for practically
538
00:47:07.680 --> 00:47:13.680
applying what's going on with the with the knee so if the knee caves in the
539
00:47:13.680 --> 00:47:13.960
foot
540
00:47:13.960 --> 00:47:20.120
will roll in the pelvis will tip forward if the knee bows out then the foot
541
00:47:20.120 --> 00:47:20.440
will
542
00:47:20.440 --> 00:47:26.280
roll outward or supinate and the pelvis will tilt backward so the knee can give
543
00:47:26.280 --> 00:47:30.240
you a really good sense of what's happening with the ankle and help you
544
00:47:30.240 --> 00:47:35.360
see what's happening with the pelvis more so if you look at them when they're
545
00:47:35.360 --> 00:47:39.280
at your golfers when they're just kind of walking and standing casually you'll
546
00:47:39.280 --> 00:47:45.790
see what kind of bias they're personal you know their normal stance is
547
00:47:45.790 --> 00:47:46.640
presenting
548
00:47:46.640 --> 00:47:59.240
all right we'll keep moving on this is where the knee becomes really critical
549
00:47:59.240 --> 00:47:59.360
for
550
00:47:59.360 --> 00:48:05.600
what's going on with the hip so this is a picture to show the glute fascia so
551
00:48:05.600 --> 00:48:09.080
your glute has two different parts the superficial and the deep and the
552
00:48:09.080 --> 00:48:16.120
superficial part goes through this it band or tractus elio tibialis and it
553
00:48:16.120 --> 00:48:21.480
connects down below the knee so the attachment for your glute the attachment
554
00:48:21.480 --> 00:48:27.040
for your biggest hip muscle your biggest rotator is below the knee it's not way
555
00:48:27.040 --> 00:48:32.520
up here where you might think and so you can you can feel it on yourself if
556
00:48:32.520 --> 00:48:38.520
you if you can relax the leg and you just put your hand on the side there's a
557
00:48:38.520 --> 00:48:43.240
little band here that's your IT band if you put it there as you raise it up you
558
00:48:43.240 --> 00:48:43.320
'll
559
00:48:43.320 --> 00:48:47.720
feel that the tension in that band changes and if you bring it all the way
560
00:48:47.720 --> 00:48:52.040
down you'll feel that that tension actually slacks unless you're like
561
00:48:52.040 --> 00:48:55.480
locking the leg and you're actually feeling one of your quad muscles if you
562
00:48:55.480 --> 00:48:59.640
can keep the leg pretty relaxed you can feel the tension in the band change so
563
00:48:59.640 --> 00:49:06.120
if you what you'll see is that first golfer that first amateur golfer who
564
00:49:06.120 --> 00:49:09.960
was keeping a lot of knee tension they weren't really using their glutes
565
00:49:09.960 --> 00:49:10.760
because
566
00:49:10.760 --> 00:49:15.720
they were bending their knee so much that they were loading more into the quad
567
00:49:15.720 --> 00:49:15.960
or
568
00:49:15.960 --> 00:49:20.800
the front of the leg or the you know the top of the way the second golfer who
569
00:49:20.800 --> 00:49:26.040
straightened the leg so much that now this lost slack he's not using his legs
570
00:49:26.040 --> 00:49:30.320
actually at all he's using more of a really big upper body power source and
571
00:49:30.320 --> 00:49:36.240
just getting that into a longer position to create tension all the way up for
572
00:49:36.240 --> 00:49:40.520
the upper body not so much the hip and the lower body but this is one of the
573
00:49:40.520 --> 00:49:46.880
most important relationships that you'll see which is the foregolf especially
574
00:49:46.880 --> 00:49:47.040
for
575
00:49:47.040 --> 00:49:52.600
that right leg if you're gonna try to use the the glutes then you want that leg
576
00:49:52.600 --> 00:49:57.560
to have or that knee to have at least 15 degrees of bend and if you want the
577
00:49:57.560 --> 00:50:03.320
knee to be able to rotate then you want it to have let's say 20 degrees of or
578
00:50:03.320 --> 00:50:03.740
or
579
00:50:03.740 --> 00:50:09.230
more bend so if you're somewhere in that 15 to 20 degree range which is where
580
00:50:09.230 --> 00:50:09.320
we
581
00:50:09.320 --> 00:50:15.040
saw all the pros then your hip and your knee will be able to function to the
582
00:50:15.040 --> 00:50:15.200
best
583
00:50:15.200 --> 00:50:21.600
of their capabilities so if I slide come back to this but if I jump back up if
584
00:50:21.600 --> 00:50:21.720
we
585
00:50:21.720 --> 00:50:27.280
look at this graph over here the green line is that trail hip or that sorry
586
00:50:27.280 --> 00:50:31.720
that trail knee and you'll see every golfer has a little different way of
587
00:50:31.720 --> 00:50:37.240
getting to that 15 to 20 degree number so here's someone who pretty much locks
588
00:50:37.240 --> 00:50:41.560
the leg but then bends it and right around change direction it's in that
589
00:50:41.560 --> 00:50:47.080
right zone here's someone who straightens it bends it straightens it and then
590
00:50:47.080 --> 00:50:54.160
it's in that 15 20 degree zone you'll tend to see you'll this is one of those
591
00:50:54.160 --> 00:50:57.260
patterns you'll see very few outliers but you'll see very different ways of
592
00:50:57.260 --> 00:51:01.880
getting there some bend it or some straighten it a lot some straighten it a
593
00:51:01.880 --> 00:51:07.640
little some straighten it or straighten it consistently to the top of the swing
594
00:51:07.640 --> 00:51:13.240
other is straighten it then bend it to get back to that number but you'll see
595
00:51:13.240 --> 00:51:19.240
that number because of its relationship with the hip and the glute is a key one
596
00:51:19.240 --> 00:51:24.840
to try to aspire to and you'll see amateurs miss that mark by pretty huge
597
00:51:24.840 --> 00:51:32.740
factors so I thought that would be an interesting piece for you guys to take
598
00:51:32.740 --> 00:51:39.060
away from this discussion on the knee because you'll see that if we went back
599
00:51:39.060 --> 00:51:43.060
and looked at the anatomy you'll see that a lot of the key muscles that work
600
00:51:43.060 --> 00:51:50.420
around the knee connect way up here by on the pelvis and so most of the muscles
601
00:51:50.420 --> 00:51:56.920
that cross the knee joint have pretty strong long levers and so the knee can
602
00:51:56.920 --> 00:52:03.380
give you a good sense of what's happening with the with the hip if the
603
00:52:03.380 --> 00:52:09.200
knee is going outward there's a good chance that the pelvis is tipping
604
00:52:09.200 --> 00:52:13.040
backward if the knee is going inward there's a good chance the pelvis is
605
00:52:13.040 --> 00:52:18.000
tipping forward there's lots of these really cool relationships between the
606
00:52:18.000 --> 00:52:24.340
two but maybe we'll do that in a second you know talk about the knee somewhere
607
00:52:24.340 --> 00:52:28.920
down the road the main goals today was to understand the basic structure and
608
00:52:28.920 --> 00:52:33.640
some of the basic relationships and start looking at it in its alignment
609
00:52:33.640 --> 00:52:39.740
between the ankle and the knee or sorry the ankle and the hip now one last
610
00:52:39.740 --> 00:52:39.920
piece
611
00:52:39.920 --> 00:52:46.960
that I wanted to address was if I go back to this running slide we are best at
612
00:52:46.960 --> 00:52:53.000
pushing force vertically when the knee and the actually forget vertically we're
613
00:52:53.000 --> 00:52:57.760
best at pushing force when the hip and the knee and the ankle are in a very
614
00:52:57.760 --> 00:53:04.080
straight line so if your golfer is getting into a position like let's say
615
00:53:04.080 --> 00:53:08.920
this was a left hand golfer and here was the top or here was the transition
616
00:53:08.920 --> 00:53:13.760
position you could see that if they were to push a lot with that lead leg with
617
00:53:13.760 --> 00:53:19.360
the knee kicked in like that they would slowly erode the inside of the leg or
618
00:53:19.360 --> 00:53:26.120
the posterior left meniscus same thing here if you see a golfer sliding like
619
00:53:26.120 --> 00:53:30.480
this they they won't be able to push vertically very well through the leg
620
00:53:30.480 --> 00:53:38.280
because the knee is out of alignment so what should happen if I back up is that
621
00:53:38.280 --> 00:53:43.360
basically when I go to the top of the swing I want to have in my right leg
622
00:53:43.360 --> 00:53:43.600
which
623
00:53:43.600 --> 00:53:49.240
is this one over here I want to have a pretty straight line of force from my
624
00:53:49.240 --> 00:53:49.480
hip
625
00:53:49.480 --> 00:53:53.280
which is right around here through the knee through kind of gyps so I have to
626
00:53:53.280 --> 00:53:58.120
make sure the knee too far outside or they tend to slide into that knee because
627
00:53:58.120 --> 00:54:05.520
the ankle was pronating a lot and now they're pushing more on the inside of
628
00:54:05.520 --> 00:54:12.160
the ankle and the outside of the knee so that's a hard one to let's say coach
629
00:54:12.160 --> 00:54:12.440
as
630
00:54:12.440 --> 00:54:18.040
far as like feeling exactly where your knee is that's where good gym exercises
631
00:54:18.040 --> 00:54:23.800
or stability training or lower body awareness and learning how to keep that
632
00:54:23.800 --> 00:54:28.560
alignment is probably easier but that is something to watch out for especially
633
00:54:28.560 --> 00:54:28.680
if
634
00:54:28.680 --> 00:54:33.720
your students are complaining about knee pain that possibly in that case you
635
00:54:33.720 --> 00:54:38.720
might have to do some spatial awareness and help them get the knee in a little
636
00:54:38.720 --> 00:54:47.960
bit better line with the ankle and the hip okay as far as knee replacements go
637
00:54:47.960 --> 00:54:52.760
this is actually pretty easy because the knee is not really a contraindication
638
00:54:52.760 --> 00:54:53.360
for
639
00:54:53.360 --> 00:54:58.880
golf the the three main things that they'll warn you about doing with a knee
640
00:54:58.880 --> 00:55:04.480
replacement like two-thirds of the population of people who get knee
641
00:55:04.480 --> 00:55:10.240
replacements complain of pain with deep flexion and some of especially the
642
00:55:10.240 --> 00:55:16.240
older knee replacement models they would say don't bend your knee passed I
643
00:55:16.240 --> 00:55:21.640
forget if it was 40 degrees or but basically don't do a deep squat don't
644
00:55:21.640 --> 00:55:26.040
bend all the way the knee is there the replacement wasn't able to handle that
645
00:55:26.040 --> 00:55:29.720
we don't get into that position in golf so that's not really an issue for us
646
00:55:29.720 --> 00:55:36.680
at all number two was impact so like sports like with a lot of running jumping
647
00:55:36.680 --> 00:55:42.440
things like that were contraindicated but they would usually say that jogging
648
00:55:42.440 --> 00:55:42.600
or
649
00:55:42.600 --> 00:55:49.280
brisk walking was fine if you look at Sasha's work the the amount of pressure
650
00:55:49.280 --> 00:55:54.720
through that lead knee is closer to one and a half of times your body weight
651
00:55:54.720 --> 00:56:01.920
which is about the same as jogging so it's not really a a deep impact or
652
00:56:01.920 --> 00:56:08.440
compressive force issue when it comes to the knee quick torsion is the the last
653
00:56:08.440 --> 00:56:13.480
contraindication which is basically like watch quick changes direction that's
654
00:56:13.480 --> 00:56:17.040
the one that you might have to be careful about especially if they have a
655
00:56:17.040 --> 00:56:22.880
transition pattern where they get the knee out of that line of hip ankle knee
656
00:56:22.880 --> 00:56:24.360
but
657
00:56:24.360 --> 00:56:27.840
in general it's going to be slow enough that it shouldn't cause too much
658
00:56:27.840 --> 00:56:34.600
problems now that being said we have to be careful with is if they had a knee
659
00:56:34.600 --> 00:56:39.520
replacement unless there was a trauma there's a very good chance that the knee
660
00:56:39.520 --> 00:56:44.760
took the beating from either a faulty moving ankle or a faulty moving hip and
661
00:56:44.760 --> 00:56:49.920
so whenever I see whenever someone tells me they had a knee injury I want to
662
00:56:49.920 --> 00:56:50.120
look
663
00:56:50.120 --> 00:56:53.820
at how the knee is moving or sorry how the hip is moving and how the ankle is
664
00:56:53.820 --> 00:56:57.760
moving because that's probably going to have a bigger impact on my coaching
665
00:56:57.760 --> 00:56:58.720
cues
666
00:56:58.720 --> 00:57:04.520
the other thing is if it was a relatively new surgery while the knee is still
667
00:57:04.520 --> 00:57:08.840
able to function it's going to feel different and it's not going to have the
668
00:57:08.840 --> 00:57:16.360
same slide they may have some clicks or you know it may not feel quite as
669
00:57:16.360 --> 00:57:21.080
comfortable and so as a result they may be tentative and not want to use their
670
00:57:21.080 --> 00:57:25.720
lower body but I've never had any any doctors that I've talked to say that
671
00:57:25.720 --> 00:57:31.040
there is like a contraindication for swinging golf club so it's usually just
672
00:57:31.040 --> 00:57:37.360
working around the psychology of what your your student is kind of having
673
00:57:37.360 --> 00:57:37.680
trouble
674
00:57:37.680 --> 00:57:44.760
with and they may have a little bit like I said trouble getting quicker ankle
675
00:57:44.760 --> 00:57:52.280
movements because of the knee so you may have to be a little bit less explosive
676
00:57:52.280 --> 00:57:55.760
with the lower body and a little bit more from your core and shoulders but I
677
00:57:55.760 --> 00:58:02.320
haven't had a need to make major changes for anyone facing knee replacement or
678
00:58:02.320 --> 00:58:08.320
who's who've successfully had a knee replacement surgery
679
00:58:08.320 --> 00:58:17.480
okay so if you have any questions please type them in the chat like I said I've
680
00:58:17.480 --> 00:58:23.720
got a one question and then a couple swings that we'll take a look at and I've
681
00:58:23.720 --> 00:58:31.480
got one ulnar deviation case study that I brought in for today so this leads
682
00:58:31.480 --> 00:58:37.320
towards one of the ideas that I'll have either next webinar or the following
683
00:58:37.320 --> 00:58:38.240
but
684
00:58:38.240 --> 00:58:41.200
the question was basically looking at the wrist that's one of the hottest
685
00:58:41.200 --> 00:58:45.680
topics though in transition do we want the lead risk going into ulnar straight
686
00:58:45.680 --> 00:58:51.560
away do you see most guys have very little addition and radial at the
687
00:58:51.560 --> 00:59:00.640
start down I'd say the majority of Torpros will have it'll stay close to the
688
00:59:00.640 --> 00:59:06.080
same you'll have a real slight ulnar deviation happening in transition but
689
00:59:06.080 --> 00:59:10.760
there is you know a good a small I shouldn't say good percentage but there's
690
00:59:10.760 --> 00:59:16.280
a percentage I don't know if it's 25 percent or 10 percent or what but guys
691
00:59:16.280 --> 00:59:23.120
who rehinge it and then start going out of it later so they rehinge it until
692
00:59:23.120 --> 00:59:26.440
about vertical as they're kind of pulling down and creating more power
693
00:59:26.440 --> 00:59:33.360
with the arms and then they start going into the ulnar deviation later so I
694
00:59:33.360 --> 00:59:40.000
typically focus more on the feeling of getting it right there unless they're
695
00:59:40.000 --> 00:59:46.560
really late the when I see on video we'll see it with the case study when I see
696
00:59:46.560 --> 00:59:51.280
on video a golfer where the wrist look like they stayed the same between about
697
00:59:51.280 --> 00:59:57.760
there and there I know we're gonna be battling some steep diggy wrist movement
698
00:59:57.760 --> 01:00:04.920
and so I usually look at it more as like at least by belly button height or
699
01:00:04.920 --> 01:00:09.200
delivery position I want to make sure that the wrist are coming out for some
700
01:00:09.200 --> 01:00:13.120
golfers they're very unaware of where the club is at the top of the swing and
701
01:00:13.120 --> 01:00:18.360
they need to start feeling it go that way much earlier but we'll probably do
702
01:00:18.360 --> 01:00:22.240
that it will probably look at actual 3D of the wrist look at details of the
703
01:00:22.240 --> 01:00:29.080
motorcycle and ulnar deviation in transition at some point here we'll come
704
01:00:29.080 --> 01:00:38.120
to that okay so here was a case study I had you know read the book came in for
705
01:00:38.120 --> 01:00:43.760
a for a lesson and I thought it'd be a good kind of practical application of
706
01:00:43.760 --> 01:00:57.560
that let's mute that okay so if I kind of scrub through you'll see as he starts
707
01:00:57.560 --> 01:01:05.840
down it's a fair but pretty good looking save from it so steep contact or steep
708
01:01:05.840 --> 01:01:10.280
position but the body is not in a very steep position so it had to be coming
709
01:01:10.280 --> 01:01:16.560
from the arms we talked a little bit about having that much radio deviation
710
01:01:16.560 --> 01:01:23.120
or hinge that late in the swing so then we did just a couple couple drills to
711
01:01:23.120 --> 01:01:27.520
work on getting this sense of feeling more of the ulnar deviation and you can
712
01:01:27.520 --> 01:01:37.160
see how his preset move is basically it's shallower and you can the the hook
713
01:01:37.160 --> 01:01:47.600
became much harder for him to accomplish so there's kind of his little let's do
714
01:01:47.600 --> 01:01:52.600
yeah it plays a little too fast okay so his preset move was really getting that
715
01:01:52.600 --> 01:02:01.320
ulnar deviation early and so you'll see now what's common what we'll probably
716
01:02:01.320 --> 01:02:07.000
have to work through next time is you'll notice that golfers who love to retain
717
01:02:07.000 --> 01:02:10.720
that radial deviation for a long period of time will typically try to shallow
718
01:02:10.720 --> 01:02:10.880
it
719
01:02:10.880 --> 01:02:18.400
more by be creating arm depth instead of that ulnar deviation but he is ulnar
720
01:02:18.400 --> 01:02:26.320
deviating now through there where if we look at originally
721
01:02:26.320 --> 01:02:32.680
bring it back not yet not yet not yet right around there right around that
722
01:02:32.680 --> 01:02:36.960
frame is kind of where he starts that ulnar deviation so we've now got it
723
01:02:36.960 --> 01:02:44.240
probably 20 30% whoops earlier which I would consider better in this particular
724
01:02:44.240 --> 01:02:51.280
movement and it will certainly help with shallowing out the bottom of the swing
725
01:02:51.280 --> 01:02:56.000
and you'll notice on the way through if you were astute you'll see that he has
726
01:02:56.000 --> 01:03:05.000
less of the stand-up move compared to where he started and so that stand-up
727
01:03:05.000 --> 01:03:10.960
move will tend to cause more of that pull hook so this was moving us in the
728
01:03:10.960 --> 01:03:20.520
right direction okay I see Craig just joined perfect because we're about to
729
01:03:20.520 --> 01:03:26.600
talk about your student and this is this is probably one of the toughest case
730
01:03:26.600 --> 01:03:32.280
studies or swing consultation questions I've gotten here so he's got a student
731
01:03:32.280 --> 01:03:36.800
who has left hemispheric cerebral palsy he was supposed to never get out of a
732
01:03:36.800 --> 01:03:41.120
wheelchair when he was born obviously he's better than that you'll see he has a
733
01:03:41.120 --> 01:03:47.120
brace on his left leg is a and I'm glad to see you on here Craig is the brace
734
01:03:47.120 --> 01:03:47.360
in
735
01:03:47.360 --> 01:03:52.800
the ankle or on the knee if you get a chance and he uses neoprene wrap on his
736
01:03:52.800 --> 01:03:58.290
left hand I assume to help stabilize the wrist he cannot process information
737
01:03:58.290 --> 01:03:58.640
when
738
01:03:58.640 --> 01:04:02.880
you talk into his left ear he needs visual problems with the left eye so he
739
01:04:02.880 --> 01:04:07.360
tends to line everything left of target would like some advice on what drills
740
01:04:07.360 --> 01:04:20.640
and ideas to help his game so let's zoom it in here
741
01:04:20.640 --> 01:04:27.200
oh whoops you guys can't see what I'm looking at can you
742
01:04:32.880 --> 01:04:42.320
okay so I know you can't see the mouse on this but
743
01:04:42.320 --> 01:04:49.640
thanks ankle perfect okay that's what it looked like but I wasn't quite sure
744
01:04:49.640 --> 01:04:51.440
okay
745
01:04:51.440 --> 01:05:01.960
so we I think you've done a tremendous job with this golf swing with all those
746
01:05:01.960 --> 01:05:09.320
limitations I mean you can see the the left wrist is pretty much bandaged up
747
01:05:09.320 --> 01:05:18.360
so the you know some whenever I'm looking at kind of a let's say a quirky
748
01:05:18.360 --> 01:05:23.080
or swing I'm looking at kind of well what's the if I could change one movement
749
01:05:23.080 --> 01:05:23.240
or
750
01:05:23.240 --> 01:05:32.680
one position what would I go after this swing to me I would use
751
01:05:32.680 --> 01:05:41.480
peterson I'm drawing a blank on his carl carl peterson I would use him as the
752
01:05:41.480 --> 01:05:48.200
model because I think that he's doing a great job of mimicking some of his
753
01:05:48.200 --> 01:05:54.280
transition moves where his body gets pretty open and out I would probably
754
01:05:54.280 --> 01:06:00.680
work on if I was trying to get into a little bit better
755
01:06:00.680 --> 01:06:07.320
bracing position I would try to get the club shallowing just a touch more there
756
01:06:07.320 --> 01:06:14.360
so that then potentially he could he could go into a little bit more bracing
757
01:06:14.360 --> 01:06:14.520
but the
758
01:06:14.520 --> 01:06:20.440
hard thing here is most of the bracing typically comes through that left leg
759
01:06:20.440 --> 01:06:26.520
and I'm not quite sure what he'll be able to do with that left ankle you'll
760
01:06:26.520 --> 01:06:33.480
see that the whole the whole lower unit basically pivots and moves like so and
761
01:06:33.480 --> 01:06:40.920
he's actually pivoting more around that right leg right the left leg the left
762
01:06:40.920 --> 01:06:41.240
leg
763
01:06:41.240 --> 01:06:47.880
is more passive in this case and where he's getting that right arm is
764
01:06:47.880 --> 01:06:54.120
quite good you know he's got a decent white movement where that right arm is
765
01:06:54.120 --> 01:07:02.440
actually working across that body it's you've done a really good job with
766
01:07:02.440 --> 01:07:07.640
building a lot of the key core pieces but one of my overriding philosophies is
767
01:07:07.640 --> 01:07:11.880
that if any golfer comes in I should be able to help them improve
768
01:07:11.880 --> 01:07:15.560
the energy you know the way that they're swinging the club
769
01:07:15.560 --> 01:07:24.040
so with him I would try and experiment with a little bit more um bracing
770
01:07:24.040 --> 01:07:31.320
so you know the bracing drill where basically I go and and pull on the club
771
01:07:31.320 --> 01:07:35.320
the danger you would have to you'd have to make sure that he turned his head so
772
01:07:35.320 --> 01:07:35.480
that he
773
01:07:35.480 --> 01:07:39.320
could hear from the right right side and see it with the right side
774
01:07:39.320 --> 01:07:47.160
and I just want to I'd do it very gently and I'd see if he was feeling it more
775
01:07:47.160 --> 01:07:47.320
in
776
01:07:47.320 --> 01:07:54.200
the left leg or if he was feeling it more in the right leg because I would I
777
01:07:54.200 --> 01:07:59.720
would tend to bet that he he's a decent driver of the golf ball and would
778
01:08:00.280 --> 01:08:07.720
struggle or complain more about low point control with his scoring irons yeah
779
01:08:07.720 --> 01:08:15.480
so you could potentially work on getting just a little bit earlier or more
780
01:08:15.480 --> 01:08:16.120
shallow
781
01:08:16.120 --> 01:08:21.720
there so then he could add the steepness of being a little bit more on that
782
01:08:21.720 --> 01:08:23.320
left side
783
01:08:23.320 --> 01:08:30.600
if he can handle it if not then by shallowing it it would allow him to get a
784
01:08:30.600 --> 01:08:31.240
little bit more
785
01:08:31.240 --> 01:08:37.240
body rotation off that right side so he might still hit him a little bit thin
786
01:08:37.240 --> 01:08:42.760
but I think it would help clean up the potential of some of the left misses
787
01:08:42.760 --> 01:08:50.680
so other than that I mean it looks like you've done a really great job with him
788
01:08:52.200 --> 01:08:56.040
because he's got limitations on the left arm and left leg I would train the
789
01:08:56.040 --> 01:08:57.160
right side
790
01:08:57.160 --> 01:09:07.000
to be as good as possible so if you're I'm not sure how detail focused you've
791
01:09:07.000 --> 01:09:08.120
been but potentially
792
01:09:08.120 --> 01:09:19.160
through there getting a little bit more of kind of that right arm staying ahead
793
01:09:19.160 --> 01:09:19.880
or
794
01:09:19.880 --> 01:09:26.120
a more of that right arm staying external a little bit longer but holy cow I
795
01:09:26.120 --> 01:09:26.840
told you this was one
796
01:09:26.840 --> 01:09:30.720
of the toughest ones when I looked at it because he checks a lot of my just
797
01:09:30.720 --> 01:09:32.360
core fundamental boxes so
798
01:09:32.360 --> 01:09:39.720
I'd say a little bit of low point control and possibly some games to try to
799
01:09:39.720 --> 01:09:43.160
dial in low point
800
01:09:43.160 --> 01:09:51.880
control and trajectory for improving his iron play so I see a question from Ed
801
01:09:51.880 --> 01:09:53.400
at regarding
802
01:09:53.400 --> 01:09:56.900
unhinging I know we have been discussing this move a fair amount but this move
803
01:09:56.900 --> 01:09:57.880
seems to be more
804
01:09:57.880 --> 01:10:04.720
of a flip as the golfer comes into impact yeah shot 39 last week also will this
805
01:10:04.720 --> 01:10:06.200
cause one to lose
806
01:10:06.200 --> 01:10:12.480
club head speed I tend to find the opposite and when you say this golfer did
807
01:10:12.480 --> 01:10:13.800
you mean the first
808
01:10:13.800 --> 01:10:22.060
one I showed or this Craig student here I tend to find that the earlier owner
809
01:10:22.060 --> 01:10:23.880
deviation doesn't
810
01:10:23.880 --> 01:10:28.620
leave club head speed because you mean you're able to increase your wrist
811
01:10:28.620 --> 01:10:29.960
extension so you're
812
01:10:29.960 --> 01:10:37.030
still able to load the wrist quite maximally you're just you're the biggest
813
01:10:37.030 --> 01:10:39.320
thing is that it tends to
814
01:10:39.320 --> 01:10:45.430
feel less flippy down at the bottom so you're able to get more club head speed
815
01:10:45.430 --> 01:10:46.520
from the body
816
01:10:46.520 --> 01:10:54.150
and the trail wrist extension you're you're not getting and you typically don't
817
01:10:54.150 --> 01:10:55.320
stall as much
818
01:10:56.040 --> 01:11:01.530
so you get the speed to build later where a lot of golfers who go into more of
819
01:11:01.530 --> 01:11:02.120
that massive
820
01:11:02.120 --> 01:11:07.800
radial actually lose like they peak their club head speed a little bit too soon
821
01:11:07.800 --> 01:11:09.640
because
822
01:11:09.640 --> 01:11:13.880
but it feels powerful that's the the one thing I'm always up against with
823
01:11:13.880 --> 01:11:15.400
training owner deviation
824
01:11:15.400 --> 01:11:20.880
is the feeling the perceived feeling of power and speed versus the actual
825
01:11:20.880 --> 01:11:22.600
reality of power and speed
826
01:11:22.600 --> 01:11:32.750
so we covered the I think that the owner deviation is one of the the two key
827
01:11:32.750 --> 01:11:33.880
shallowing movements for
828
01:11:33.880 --> 01:11:38.810
the arms and so if you want to have a good wipe you need it if you want to have
829
01:11:38.810 --> 01:11:40.120
less of a stall you
830
01:11:40.120 --> 01:11:45.710
need it I just think it's a really important movement for developing a really
831
01:11:45.710 --> 01:11:46.840
good flat spot
832
01:11:46.840 --> 01:11:58.840
down at the bottom so the and the thing is here let me pull up
833
01:12:01.000 --> 01:12:10.680
since we're answering some chats anyway okay so when you go in towards when you
834
01:12:10.680 --> 01:12:11.880
go in towards
835
01:12:11.880 --> 01:12:16.260
owner deviation it makes it really hard to flip a flip is when you're going
836
01:12:16.260 --> 01:12:18.840
into either increased
837
01:12:18.840 --> 01:12:24.630
extension or increased flexion of the trail wrist so that way this way is
838
01:12:24.630 --> 01:12:27.400
actually one of the key
839
01:12:28.040 --> 01:12:33.960
components going that way is what gets the club in line with the forearm so it
840
01:12:33.960 --> 01:12:35.160
can actually
841
01:12:35.160 --> 01:12:41.790
and it because it's coupled with flexion it'll actually delay the the flipping
842
01:12:41.790 --> 01:12:43.080
of the club so
843
01:12:43.080 --> 01:12:47.880
it tends to help with low point and like I said if you get past the feeling of
844
01:12:47.880 --> 01:12:49.320
it being less powerful
845
01:12:49.320 --> 01:12:53.910
and if you're capable of creating speed from your hips in your core then it
846
01:12:53.910 --> 01:12:55.080
ends up producing
847
01:12:55.080 --> 01:13:00.570
more club head speed but feeling slower it's a weird pattern but i've seen it
848
01:13:00.570 --> 01:13:01.400
consistently enough
849
01:13:01.400 --> 01:13:06.390
that i'm pretty confident with it um is there a optimal pattern for hip
850
01:13:06.390 --> 01:13:07.880
rotation for example
851
01:13:07.880 --> 01:13:14.030
supinating both ankles and straightening the left leg faster um it's a good
852
01:13:14.030 --> 01:13:16.600
question um i've got
853
01:13:18.040 --> 01:13:23.530
because i have guys who have really high club head speeds and really high
854
01:13:23.530 --> 01:13:24.600
performance on
855
01:13:24.600 --> 01:13:33.230
like there were some pretty solid golfers i used in the powerpoint today on
856
01:13:33.230 --> 01:13:35.560
both ends of the spectrum
857
01:13:35.560 --> 01:13:41.160
so one of the golfer who had the dual external rotation is a very good ball
858
01:13:41.160 --> 01:13:42.120
striker world class
859
01:13:42.120 --> 01:13:48.060
and one of the golfers who had the look of less external rotation is you know
860
01:13:48.060 --> 01:13:49.000
top 10
861
01:13:49.000 --> 01:13:55.240
one of the guys that you commonly see as an example of an elite ball striker so
862
01:13:55.240 --> 01:13:56.440
i don't necessarily
863
01:13:56.440 --> 01:14:02.820
think that there is that one is vastly superior to the other um but i do think
864
01:14:02.820 --> 01:14:04.680
that the supination
865
01:14:04.680 --> 01:14:16.360
pattern um possibly requires less nuance in the release um so the the danger
866
01:14:16.360 --> 01:14:17.560
the danger of going
867
01:14:17.560 --> 01:14:21.630
the opposite where you have more of the pronation pattern is i think that you
868
01:14:21.630 --> 01:14:23.560
run into some barriers
869
01:14:23.560 --> 01:14:27.440
in the left leg so you have to have a little bit more of the vertical coming
870
01:14:27.440 --> 01:14:28.600
off the ground and have
871
01:14:28.600 --> 01:14:34.280
it really spin in the air um in order to get through the ball without stalling
872
01:14:34.280 --> 01:14:35.560
uh and i think
873
01:14:35.560 --> 01:14:41.410
that that can create a little bit more timing issues um i don't i don't
874
01:14:41.410 --> 01:14:44.200
necessarily think that
875
01:14:44.200 --> 01:14:53.080
one is vastly superior in terms of the um power output um now for the trail leg
876
01:14:53.080 --> 01:14:54.040
as far as the
877
01:14:54.040 --> 01:14:59.220
amount of timing of the knee straightening i do think there is you know you you
878
01:14:59.220 --> 01:15:00.520
saw that there
879
01:15:00.520 --> 01:15:04.800
are a couple different ways to hit that zone but if you're not loading the
880
01:15:04.800 --> 01:15:06.680
ankle and the the hip
881
01:15:06.680 --> 01:15:11.190
then i think you're leaving a lot out there and that's where a lot a lot more
882
01:15:11.190 --> 01:15:11.960
amateurs in my
883
01:15:11.960 --> 01:15:17.000
opinion suffer from poor trail leg mechanics then lead leg mechanics
884
01:15:17.000 --> 01:15:30.200
okay i had one other golfer to take a look at um let's zoom in
885
01:15:33.800 --> 01:15:42.360
just leave it like this okay so Ian sent in one of his students
886
01:15:42.360 --> 01:15:49.320
and we've got it kind of in frame by frame mode
887
01:15:49.320 --> 01:16:00.990
okay so i'll let you you know think about it gather your thoughts before i jump
888
01:16:00.990 --> 01:16:01.160
in
889
01:16:03.960 --> 01:16:11.800
okay and then we'll move over to the down the line
890
01:16:33.880 --> 01:16:38.360
okay you got some ideas
891
01:16:38.360 --> 01:16:44.840
if you want to comment you can so if i was looking through this golfer um some
892
01:16:44.840 --> 01:16:46.520
of the questions i
893
01:16:46.520 --> 01:16:52.020
would be asking um i think that um the the priorities that i tend to go at um i
894
01:16:52.020 --> 01:16:53.560
talked about in the
895
01:16:53.560 --> 01:16:59.050
the level two a couple weeks ago um i try to go for solid contact then straight
896
01:16:59.050 --> 01:16:59.640
then far
897
01:17:00.520 --> 01:17:05.370
usually in that order i imagine that this golfer tends to have more straight
898
01:17:05.370 --> 01:17:08.200
ness uh than solid
899
01:17:08.200 --> 01:17:13.210
contact if you look at it you know if we go to impact and and just look at some
900
01:17:13.210 --> 01:17:14.760
rough kind of
901
01:17:14.760 --> 01:17:21.160
path ideas it tends to be i'd say straighter than if i brought it back and we
902
01:17:21.160 --> 01:17:22.520
looked at more
903
01:17:23.640 --> 01:17:29.120
the low point considerations which would be where is this sternum and and where
904
01:17:29.120 --> 01:17:29.880
is his arms
905
01:17:29.880 --> 01:17:38.840
so at impact that's fairly vertical and a little bit more more back so now i'm
906
01:17:38.840 --> 01:17:39.320
going to
907
01:17:39.320 --> 01:17:44.360
relate the two together now the good news i would if i was working with this
908
01:17:44.360 --> 01:17:45.640
golfer in person and
909
01:17:45.640 --> 01:17:49.870
say okay you've got great arm extension that's going to be a huge benefit um we
910
01:17:49.870 --> 01:17:51.000
've got a pretty
911
01:17:51.640 --> 01:17:58.680
stable yeah right uh i agree with drive hold right arm straightens too soon
912
01:17:58.680 --> 01:18:00.200
lack of white movement
913
01:18:00.200 --> 01:18:05.040
so we'll we'll circle back to that um so there's where we can see that the
914
01:18:05.040 --> 01:18:06.680
right arm is straightening
915
01:18:06.680 --> 01:18:11.620
too soon so as a result the shaft is pretty vertical at impact but he does a
916
01:18:11.620 --> 01:18:13.080
pretty good job of
917
01:18:13.080 --> 01:18:17.760
getting into some good arm extension on the way through i just don't love the
918
01:18:17.760 --> 01:18:19.080
way he gets there
919
01:18:19.080 --> 01:18:24.130
so i would imagine that solid contact is one of our bigger issues i'm actually
920
01:18:24.130 --> 01:18:24.600
gonna
921
01:18:24.600 --> 01:18:28.680
pull him up in both spots we'll see if we can do it this way
922
01:18:28.680 --> 01:18:39.880
all right way to trick it okay so now
923
01:18:44.200 --> 01:18:50.440
so now if we look at when so right around here is where something that looks
924
01:18:50.440 --> 01:18:51.480
off right there's a
925
01:18:51.480 --> 01:18:56.970
lot of space there um the arms are way behind his body if i bring it down to
926
01:18:56.970 --> 01:18:58.360
about the same position
927
01:18:58.360 --> 01:19:03.320
from the down the line you'd say oh this looks like it's way inside but the
928
01:19:03.320 --> 01:19:04.680
reason that it looks
929
01:19:04.680 --> 01:19:11.310
way inside is because there's not a lot of body rotation at this point right
930
01:19:11.310 --> 01:19:13.640
you can see his hips
931
01:19:13.640 --> 01:19:20.360
and his chest are at the most pointing at the golf ball but probably close to
932
01:19:20.360 --> 01:19:21.240
the target
933
01:19:21.240 --> 01:19:26.460
so if i was to grab the club and freeze him there and then have him turn his
934
01:19:26.460 --> 01:19:28.200
body more towards the
935
01:19:28.200 --> 01:19:34.450
target what would happen is that elbow would work its way more in front in
936
01:19:34.450 --> 01:19:37.400
order to um allow for the
937
01:19:37.400 --> 01:19:43.240
left arm to stay in contact so i think that this is more of a sequencing issue
938
01:19:43.240 --> 01:19:43.480
can
939
01:19:43.480 --> 01:19:51.480
creating a low point issue now we usually when you start getting the body more
940
01:19:51.480 --> 01:19:52.280
open
941
01:19:52.280 --> 01:19:57.170
there's a chance that the the face will get left open when he gets more shaft
942
01:19:57.170 --> 01:19:57.880
lean so that'd be
943
01:19:57.880 --> 01:20:03.700
something that i would at least experiment with or keep an eye on but the main
944
01:20:03.700 --> 01:20:05.000
issue i see for him
945
01:20:05.000 --> 01:20:09.330
would be getting a little bit improved sequencing um which would help keep the
946
01:20:09.330 --> 01:20:10.600
arms more in front
947
01:20:10.600 --> 01:20:18.280
so a pump drill or um you know some rope training or uh you know if you know
948
01:20:18.280 --> 01:20:19.160
some of the hands-on
949
01:20:19.160 --> 01:20:24.650
stuff where you're going in um i would do the one where i like to hold on to
950
01:20:24.650 --> 01:20:27.480
the club and get the
951
01:20:27.480 --> 01:20:30.650
body to feel more open or if you were doing it by yourself you would use
952
01:20:30.650 --> 01:20:32.040
something like the wall
953
01:20:32.040 --> 01:20:37.880
drill um or the reverse pump like all those would kind of help get a sense of
954
01:20:37.880 --> 01:20:39.800
the arms more in front
955
01:20:39.800 --> 01:20:45.900
now the thing that he will have to adjust for is if we look at the height there
956
01:20:45.900 --> 01:20:47.800
you'll notice
957
01:20:47.800 --> 01:20:56.200
that if we were to delay that right arm he would probably top the ball unless
958
01:20:56.200 --> 01:20:58.920
he in addition to
959
01:20:58.920 --> 01:21:04.870
getting more body rotation also um got a little bit more bent over um to
960
01:21:04.870 --> 01:21:07.240
account for the distance
961
01:21:07.240 --> 01:21:11.320
difference in the right arm straightening so i would experiment with some
962
01:21:11.320 --> 01:21:12.440
transition pump type
963
01:21:12.440 --> 01:21:17.480
stuff and then i would probably circle back to some impact or release drills
964
01:21:17.480 --> 01:21:18.840
feeling closer to
965
01:21:18.840 --> 01:21:24.130
the ground um i i tell golfers all the time that there's two ways to avoid
966
01:21:24.130 --> 01:21:25.640
hitting it fat one is
967
01:21:25.640 --> 01:21:30.440
standing up and when you straighten your arm or two is rotating so that you
968
01:21:30.440 --> 01:21:31.560
delay the timing of
969
01:21:31.560 --> 01:21:36.280
when that right arm straightens and i think that i would want to do the second
970
01:21:36.280 --> 01:21:36.920
with him
1
00:00:00.000 --> 00:00:07.500
on the 3d side we are going to look at the idea of dual external rotation where
2
00:00:07.500 --> 00:00:13.920
basically the discussing the look of golfers you tend to get more kind of
3
00:00:13.920 --> 00:00:19.500
knees spread apart the same squat same steam squat versus golfers you tend to
4
00:00:19.500 --> 00:00:23.760
have a little bit more of a movement where everything kind of drifts so we're
5
00:00:23.760 --> 00:00:28.920
gonna look at that as it relates to 3d graphs get hopefully a clearer idea of
6
00:00:28.920 --> 00:00:35.280
what's going on there anatomy we're going to take a look at some basic knee
7
00:00:35.280 --> 00:00:40.280
anatomy so not the super advanced fascia stuff but we'll look at the joint and
8
00:00:40.280 --> 00:00:47.640
the muscles and the implications for golf and we'll briefly discuss if you're
9
00:00:47.640 --> 00:00:52.040
working with a client who has a knee replacement what are some possible things
10
00:00:52.040 --> 00:00:58.080
that you have to consider and then we've got of just a couple questions and we
11
00:00:58.080 --> 00:00:58.080
've
12
00:00:58.080 --> 00:01:06.520
got a few swings to take a look at so shouldn't be a terribly long call unless
13
00:01:06.520 --> 00:01:13.120
there's a whole bunch of live questions but let's get into the fun topic here
14
00:01:13.120 --> 00:01:14.640
so
15
00:01:14.640 --> 00:01:24.920
let me switch that over all right so what will I've got five different pro
16
00:01:24.920 --> 00:01:25.320
swings
17
00:01:25.320 --> 00:01:30.280
and then two different amateur swings and for the pro swings I wanted you to be
18
00:01:30.280 --> 00:01:37.440
able to visualize it so I'm gonna let the five swings kind of play through so
19
00:01:37.440 --> 00:01:43.440
you'll see it switch over try not to guess or type in the chat if you think
20
00:01:43.440 --> 00:01:49.760
you know who it is but I'll go kind of at regular speed and then a little bit
21
00:01:49.760 --> 00:01:55.320
of frame by frame there and we'll jump back and forth after we look at the
22
00:01:55.320 --> 00:02:02.520
graphs so this is one of the classic examples for looking at kind of dual
23
00:02:02.520 --> 00:02:12.240
external rotation right getting into that really wide Sam's the squat look and
24
00:02:12.240 --> 00:02:20.160
then we've got a couple others who are let's say more kind of in the middle and
25
00:02:20.160 --> 00:02:25.560
then we'll end with one more who has a really classic look of the dual
26
00:02:25.560 --> 00:02:32.800
external rotation but while we're going through this if you're if you're on go
27
00:02:32.800 --> 00:02:37.760
ahead and type in the in the chat just so I kind of have an idea of who's who's
28
00:02:37.760 --> 00:02:47.000
listening in where the questions might be coming from so here we have good and
29
00:02:47.000 --> 00:02:54.680
then this is the last golfer believe kind of has that classic look of the
30
00:02:54.680 --> 00:03:01.840
lead leg moving away from the trail leg in transition so there you can see
31
00:03:01.840 --> 00:03:06.040
lead leg doesn't look like it moves a whole lot trail leg moving away from it
32
00:03:06.040 --> 00:03:12.840
okay so now we're gonna go through each of these golfers and I'll I'll go back
33
00:03:12.840 --> 00:03:18.600
and and kind of play them in between looking at each cluster but I got a
34
00:03:18.600 --> 00:03:25.680
handful of graphs that we'll look at that all relate to this idea of the knee
35
00:03:25.680 --> 00:03:31.640
and the hip and the ankle creating that look of dual external rotation so I'll
36
00:03:31.640 --> 00:03:35.720
just go through the graphs first and then we'll we'll talk about each golfer
37
00:03:35.720 --> 00:03:36.680
kind
38
00:03:36.680 --> 00:03:42.680
of as a whole so I guess I'll start down here at the bottom so this is internal
39
00:03:42.680 --> 00:03:49.040
versus external hip rotation when the graph goes positive or up it's going
40
00:03:49.040 --> 00:03:53.760
into internal rotation and when it goes negative it's going into external
41
00:03:53.760 --> 00:04:00.640
rotation we'll see that this is even though it's described as an external
42
00:04:00.640 --> 00:04:06.480
rotation of the lead knee often we'll see that this is one of the least useful
43
00:04:06.480 --> 00:04:12.160
graphs for diagnosing that pattern okay so now if we jump up top here we've got
44
00:04:12.160 --> 00:04:21.280
hip ABduction ADduction so ABduction is if it's going negative which is the
45
00:04:21.280 --> 00:04:28.280
basically like doing the splits so the the hip is opening up and then AD
46
00:04:28.280 --> 00:04:32.560
ADduction is when the knees are coming closer together coming towards the
47
00:04:32.560 --> 00:04:37.840
midline and that's if it's going positive and we've got knee sway so
48
00:04:37.840 --> 00:04:42.200
basically looking at the horizontal displacement towards or away from the
49
00:04:42.200 --> 00:04:50.280
target as the golfer is going through the swing in all of these cases I believe
50
00:04:50.280 --> 00:04:56.600
the green line is the trail hip and the red line is the lead knee or hip I
51
00:04:56.600 --> 00:04:56.920
should
52
00:04:56.920 --> 00:05:02.410
say then we're looking at knee bend this is an interesting graph to look at we
53
00:05:02.410 --> 00:05:02.680
'll
54
00:05:02.680 --> 00:05:05.740
talk a little bit about this especially with one of the amateurs or actually
55
00:05:05.740 --> 00:05:12.920
both of the amateurs so looking at the trail knee as the green line possibly
56
00:05:12.920 --> 00:05:17.880
having a little bit of bend and then or sorry straightening a little bit when
57
00:05:17.880 --> 00:05:17.960
it
58
00:05:17.960 --> 00:05:23.240
goes negative it's straightening when it goes positive it is bending more so
59
00:05:23.240 --> 00:05:29.840
we'll address this pattern and then looking at hip flexion extension so
60
00:05:29.840 --> 00:05:35.440
you'll see usually an inverse pair in transition and then we'll talk about
61
00:05:35.440 --> 00:05:41.640
what happens a little bit in the downswing knee separation is when they talk
62
00:05:41.640 --> 00:05:47.320
about getting your hips or your knees away from each other knee separation
63
00:05:47.320 --> 00:05:47.480
would
64
00:05:47.480 --> 00:05:53.520
be the absolute measurement of the distance between your knees now it's in
65
00:05:53.520 --> 00:05:58.360
3d space so you could keep them the same distance apart but they would look
66
00:05:58.360 --> 00:05:58.560
like
67
00:05:58.560 --> 00:06:03.680
they increased from a face on camera view or vice versa but this is just
68
00:06:03.680 --> 00:06:09.920
looking at the actual 3d space between the knees and then the last graph graph
69
00:06:09.920 --> 00:06:14.720
is looking at the ankle and looking at the pronation supination so we covered
70
00:06:14.720 --> 00:06:20.640
that a little bit we covered the motion in last month's call but this month we
71
00:06:20.640 --> 00:06:20.680
're
72
00:06:20.680 --> 00:06:23.760
gonna look at the graph as it relates to this knee separation because it's
73
00:06:23.760 --> 00:06:29.520
actually one of the most important ones for looking at lead hip the look of
74
00:06:29.520 --> 00:06:29.880
dual
75
00:06:29.880 --> 00:06:39.440
external rotation okay so now let's let's jump through these again this is what
76
00:06:39.440 --> 00:06:47.320
we'll do for each golfer we'll let it play so here we go so this is the first
77
00:06:47.320 --> 00:06:54.400
example you'll see in transition it's kind of a little bit of you might call
78
00:06:54.400 --> 00:07:00.080
it a rotation you'll see the pelvis looks like it rotates into the thigh the
79
00:07:00.080 --> 00:07:03.680
trail knee comes with it a little bit and then it starts to get into a vertical
80
00:07:03.680 --> 00:07:14.000
movement okay so now here's that pattern so the the trail hip during the back
81
00:07:14.000 --> 00:07:14.200
swing
82
00:07:14.200 --> 00:07:20.560
is going to go into internal rotation and then briefly before the top of the
83
00:07:20.560 --> 00:07:24.320
swing it will start to go into external rotation that will continue all the way
84
00:07:24.320 --> 00:07:31.320
through impact the lead knee is going to go into external rotation during the
85
00:07:31.320 --> 00:07:36.520
backswing reaching close to its maximum range and then right around the same
86
00:07:36.520 --> 00:07:43.040
time as the pelvis changes direction the hip is going to go into or start
87
00:07:43.040 --> 00:07:47.120
working towards internal rotation doesn't actually reach internal rotation
88
00:07:47.120 --> 00:07:54.000
until after impact but it's moving internally what you'll see here is down
89
00:07:54.000 --> 00:07:57.880
near impact there'll be a blip where it goes external that's usually when the
90
00:07:57.880 --> 00:08:05.680
golfer's lead leg is off the ground and so the foot now is able to pivot
91
00:08:05.680 --> 00:08:13.360
without friction holding it back but you'll you'll see that once the pelvis
92
00:08:13.360 --> 00:08:21.120
starts to rotate towards the target you'll have to have this pattern of lead
93
00:08:21.120 --> 00:08:25.200
hip internal trail hip external especially because you're reaching near
94
00:08:25.200 --> 00:08:28.640
maximum range of motion with that lead hip as you approach the top of the
95
00:08:28.640 --> 00:08:33.760
backswing so what we'll see through the five graphs or the five pro examples is
96
00:08:33.760 --> 00:08:39.720
that this is one of the least indicative of the actual dual external rotation
97
00:08:39.720 --> 00:08:46.240
okay now if we look at abduction adduction this is another one that golfer's
98
00:08:46.240 --> 00:08:51.480
would commonly associate with the the look of dual external rotation if we look
99
00:08:51.480 --> 00:08:58.040
at the trail hip it's going to be adducting because basically the the pelvis
100
00:08:58.040 --> 00:09:01.760
is moving towards the leg and then during the downswing you're gonna see
101
00:09:01.760 --> 00:09:08.840
it abduct or move away we're gonna see basically the opposite pattern with a
102
00:09:08.840 --> 00:09:16.240
slight variation in the timing of when it goes from from abduction to adduction
103
00:09:16.240 --> 00:09:20.800
but you'll see that during pretty much the entire downswing that lead leg is
104
00:09:20.800 --> 00:09:26.800
going into a significant amount of adduction this one has some interesting
105
00:09:26.800 --> 00:09:31.620
characteristics but similar to internal external it's that it definitely doesn
106
00:09:31.620 --> 00:09:31.720
't
107
00:09:31.720 --> 00:09:39.720
tell a whole lot of the story if we jump down diagonally knee separation will
108
00:09:39.720 --> 00:09:44.480
give us a good estimate of that look so the golfers who have more of that squat
109
00:09:44.480 --> 00:09:49.640
look you will see an increase in the space between the knees now remember it's
110
00:09:49.640 --> 00:09:49.720
a
111
00:09:49.720 --> 00:09:55.960
3d space so some of that is coming from the rotation of the pelvis where if one
112
00:09:55.960 --> 00:10:01.920
leg stays in place and the other leg is following more of the rotation of the
113
00:10:01.920 --> 00:10:10.200
pelvis those will tend to in get further apart now the two most interesting for
114
00:10:10.200 --> 00:10:14.800
this pattern are actually looking at the knee bend and the ankle pronation
115
00:10:14.800 --> 00:10:24.720
supination so if we look at the lead knee or the lead leg I should say then
116
00:10:24.720 --> 00:10:25.240
what
117
00:10:25.240 --> 00:10:30.400
we'll see during the the backswing is that the lead foot is actually going to
118
00:10:30.400 --> 00:10:37.200
supinate slightly and then during transition it's going to pronate so I'll
119
00:10:37.200 --> 00:10:43.360
bring my camera real quick so when we're looking at the foot basically during
120
00:10:43.360 --> 00:10:43.760
the
121
00:10:43.760 --> 00:10:47.760
backswing it's actually supinating a little bit like this and then during the
122
00:10:47.760 --> 00:10:53.760
downswing this golfer is actually going to roll that foot in and it's pretty
123
00:10:53.760 --> 00:10:59.480
significant 10 15 degrees or so so if you if you can see my leg my left leg
124
00:10:59.480 --> 00:11:06.120
right here when I roll that foot in as my pelvis is going to turn that's gonna
125
00:11:06.120 --> 00:11:13.960
create the look of more internal rotation but that and that are pretty much the
126
00:11:13.960 --> 00:11:18.280
same I'm kind of holding this in place so that I have a good reference that's
127
00:11:18.280 --> 00:11:25.160
the same amount of internal rotation of the hip but I was moving my knee from
128
00:11:25.160 --> 00:11:25.400
the
129
00:11:25.400 --> 00:11:30.920
ankle going into pronation or supination what we'll see with the two golfers
130
00:11:30.920 --> 00:11:31.040
who
131
00:11:31.040 --> 00:11:37.640
have more of the pronounced external rotation look is that they're gonna go
132
00:11:37.640 --> 00:11:40.960
into supination of the trail foot where the golfers who have more of that
133
00:11:40.960 --> 00:11:48.840
internal rotation look go into pronation of that lead ankle so let's go back to
134
00:11:48.840 --> 00:11:53.800
where you can see my mouse okay so it's a really clear either this line is
135
00:11:53.800 --> 00:11:54.080
going
136
00:11:54.080 --> 00:11:59.040
down therefore it's pronating or it's going up therefore it's supinating
137
00:11:59.040 --> 00:12:06.400
trail ankle doesn't have as clear pattern but because it's very hard to
138
00:12:06.400 --> 00:12:13.280
supinate a ton when you're shifting your pelvis to the left but we'll focus
139
00:12:13.280 --> 00:12:17.700
primarily on the knee on the lead leg there and then we'll talk about knee
140
00:12:17.700 --> 00:12:24.120
bends they they have a little bit of an impact on the the look of internal
141
00:12:24.120 --> 00:12:27.440
external but they're just more of a good pattern to start understanding because
142
00:12:27.440 --> 00:12:32.200
this is where you'll see a fair amount of the difference between the pros and
143
00:12:32.200 --> 00:12:32.280
the
144
00:12:32.280 --> 00:12:40.290
amps so the normal pattern is straighten a little bit in the backswing bend we
145
00:12:40.290 --> 00:12:40.800
're
146
00:12:40.800 --> 00:12:44.640
looking at the trail knee straighten a bit in the backswing increase the flex
147
00:12:44.640 --> 00:12:49.360
past where it was to start in the early downswing and then straighten late and
148
00:12:49.360 --> 00:12:54.850
you'll see both legs and this particular golfer very close to straight when he
149
00:12:54.850 --> 00:12:54.880
's
150
00:12:54.880 --> 00:13:00.840
actually making contact with a golf ball okay so now we'll jump into the second
151
00:13:00.840 --> 00:13:13.600
one let's see how well we and the second one is one of the golfers who is
152
00:13:13.600 --> 00:13:24.120
classically used as an example of the dual external rotation so you'll see
153
00:13:24.120 --> 00:13:30.840
the space between the legs really increasing and they are definitely the
154
00:13:30.840 --> 00:13:35.640
space between the legs is definitely increasing okay so that was option number
155
00:13:35.640 --> 00:13:43.080
two here are option number two or pro number two's graph so if we look at
156
00:13:43.080 --> 00:13:47.160
internal versus external what you'll actually see is this golfer who looks
157
00:13:47.160 --> 00:13:52.880
like he's going into massive external rotation is actually going into internal
158
00:13:52.880 --> 00:14:00.480
rotation much earlier than the golfer who didn't have the same look so that's
159
00:14:00.480 --> 00:14:04.710
kind of one of the optical illusions if you're just looking at where the knee
160
00:14:04.710 --> 00:14:04.800
is
161
00:14:04.800 --> 00:14:11.800
pointing and using that as a reference as to what the the hip is doing if we
162
00:14:11.800 --> 00:14:20.040
look at abduction adduction you'll see even though it looks like that lead leg
163
00:14:20.040 --> 00:14:26.760
is pulling away and going into more abduction you can see that it's actually
164
00:14:26.760 --> 00:14:32.000
slightly moving towards adduction it's not moving at a great rate but it's
165
00:14:32.000 --> 00:14:39.880
moving towards adduction okay if we go over to the pronation supination graph
166
00:14:39.880 --> 00:14:45.200
when we look at the lead ankle so the red line you'll see that as he changes
167
00:14:45.200 --> 00:14:51.640
direction that lead leg or that lead ankle is going into almost 15 degrees of
168
00:14:51.640 --> 00:14:56.960
supination if I click back so you can compare you can see there's a big
169
00:14:56.960 --> 00:15:03.380
difference between the red line going down and the red line going up and they
170
00:15:03.380 --> 00:15:03.440
're
171
00:15:03.440 --> 00:15:07.800
going about the same amount the same magnitude but in totally opposite
172
00:15:07.800 --> 00:15:15.000
opposite directions so in one sense the that lead foot is driving where the
173
00:15:15.000 --> 00:15:15.160
knee
174
00:15:15.160 --> 00:15:21.600
is going more so than what this golfer is doing with the hip and you can also
175
00:15:21.600 --> 00:15:26.760
see that there is a difference between what's happening with the trail ankle so
176
00:15:26.760 --> 00:15:34.560
the golfer who is going more in into the less external direction that lead or
177
00:15:34.560 --> 00:15:40.360
sorry that trail ankle is going into supination where here it's going
178
00:15:40.360 --> 00:15:45.920
slightly into pronation or pretty much staying closer to the same it really
179
00:15:45.920 --> 00:15:50.160
doesn't start pronating until later in the downswing but the lead ankle going
180
00:15:50.160 --> 00:15:54.240
into supination is something that you'll classically see with the golfers who
181
00:15:54.240 --> 00:16:01.440
have that dual external rotation look more so than the hip ABA deduction or
182
00:16:01.440 --> 00:16:06.360
internal external rotation or flexion extension I'm not really even talking
183
00:16:06.360 --> 00:16:11.240
about flexion extension because it's a really minor part of this equation
184
00:16:11.240 --> 00:16:20.200
typically basically in order to rotate you would have to have one hip going
185
00:16:20.200 --> 00:16:26.680
into extension and one hip going into flexion so you'll typically see these
186
00:16:26.680 --> 00:16:30.800
two going together when or going in slightly opposite directions when it's
187
00:16:30.800 --> 00:16:35.960
rotating and then you'll see them both go into extension as they're applying
188
00:16:35.960 --> 00:16:36.320
more
189
00:16:36.320 --> 00:16:41.200
of the vertical force but this pattern this graph you'll see if I just quickly
190
00:16:41.200 --> 00:16:46.160
jump through all five of them you'll see the magnitudes are slightly different
191
00:16:46.160 --> 00:16:52.600
but the overall pattern is fairly consistent even with the higher handicap
192
00:16:52.600 --> 00:16:59.480
golfers you rarely see a huge deviation there okay so back to the important one
193
00:16:59.480 --> 00:17:07.080
of the you know looking at more of the knee separation the left leg looking
194
00:17:07.080 --> 00:17:07.240
like
195
00:17:07.240 --> 00:17:12.800
it goes into external rotation the other piece to look at is the knee bend
196
00:17:12.800 --> 00:17:19.480
here so you'll tend to see that part of what creates that separation look is
197
00:17:19.480 --> 00:17:21.040
the
198
00:17:21.040 --> 00:17:31.360
lead knee going into more of a extension position or starting to
199
00:17:31.360 --> 00:17:36.840
straighten as it's going into the change direction as the trail leg is
200
00:17:36.840 --> 00:17:41.720
bending more as opposed to with the golfer who had more of the internal
201
00:17:41.720 --> 00:17:47.080
rotation look you would see that the lead knee was actually bending more so
202
00:17:47.080 --> 00:17:52.160
getting an earlier straightening of that leg with the supination is going to
203
00:17:52.160 --> 00:17:52.400
create
204
00:17:52.400 --> 00:18:00.920
that giant squat look or the increase in the distance between the knees there's
205
00:18:00.920 --> 00:18:07.880
some other things going on in terms of rotation but these are the the core too
206
00:18:07.880 --> 00:18:21.520
okay so now if we jump to the third golfer so that's the second golfer we'll
207
00:18:21.520 --> 00:18:21.640
try
208
00:18:21.640 --> 00:18:25.560
to do a better job paying attention to the timestamp so I can jump right to it
209
00:18:25.560 --> 00:18:38.400
next time okay so he's at 41 all right so we'll watch this one this is a very
210
00:18:38.400 --> 00:18:42.400
good ball striker you'll see it's kind of got a little bit more of almost
211
00:18:42.400 --> 00:18:43.560
hybrid
212
00:18:43.560 --> 00:18:53.000
where it's it doesn't have a really big squat separation look but it also you
213
00:18:53.000 --> 00:18:57.440
know that might look like it's going in internal rotation by some but it doesn
214
00:18:57.440 --> 00:18:57.520
't
215
00:18:57.520 --> 00:19:02.440
look like the trail leg is coming along in the early stages it it comes along a
216
00:19:02.440 --> 00:19:09.480
little bit later okay okay so looking at that golfer we're gonna jump to his
217
00:19:09.480 --> 00:19:14.760
graphs and move a little bit quicker so we'll see again that usually when it
218
00:19:14.760 --> 00:19:20.480
looks like it's going into external rotation it's actually going into internal
219
00:19:20.480 --> 00:19:28.800
rotation quicker or earlier and then if we look at the ankle we saw again with
220
00:19:28.800 --> 00:19:33.800
the external rotation look it's gonna have more of going positive or supination
221
00:19:33.800 --> 00:19:39.600
the golfer is having more of the pronated look that's probably if you just
222
00:19:39.600 --> 00:19:45.640
needed one graph to look at that knee separation look other than looking at
223
00:19:45.640 --> 00:19:50.400
knee separation this would be the one that would tell you most clearly what
224
00:19:50.400 --> 00:19:53.800
their legs are gonna look like or what their knees are going to look like in
225
00:19:53.800 --> 00:20:03.480
transition now this golfer also you'll see has a fair amount of lead knee bend
226
00:20:03.480 --> 00:20:03.880
in
227
00:20:03.880 --> 00:20:08.200
transition and that typically keeps the knees closer together then if the lead
228
00:20:08.200 --> 00:20:18.020
knee starts to straighten earlier if we look at the abduction adduction this
229
00:20:18.020 --> 00:20:25.120
golfer is actually at abducting the leg so you would think that you would have
230
00:20:25.120 --> 00:20:30.960
more of a increase but because of what's happening at the ankle and what's
231
00:20:30.960 --> 00:20:36.600
happening at the flex in the trail knee those knees are staying closer together
232
00:20:36.600 --> 00:20:44.200
so it has more of that kind of less of the dual external rotation squat look
233
00:20:44.200 --> 00:20:45.200
that
234
00:20:45.200 --> 00:20:53.640
squat comes from straightening that lead knee supinating that lead foot and
235
00:20:53.640 --> 00:20:54.600
those
236
00:20:54.600 --> 00:20:59.080
are the the main two that you'll see more so than the adduction more so than
237
00:20:59.080 --> 00:21:09.680
that internal rotation so nothing else major to note here so we'll we'll move
238
00:21:09.680 --> 00:21:16.720
on the one of the interesting things about we're gonna come after we go
239
00:21:16.720 --> 00:21:20.160
through the pros we'll compare the amateurs and you'll see that while the
240
00:21:20.160 --> 00:21:25.280
knees have some interesting looks in the backswing that trail knee almost
241
00:21:25.280 --> 00:21:25.880
always
242
00:21:25.880 --> 00:21:33.240
is around 15 to 20 degrees closer to 15 degrees at the top of the swing there
243
00:21:33.240 --> 00:21:39.720
there are some outliers but we're gonna talk about why that 15 degree bend in
244
00:21:39.720 --> 00:21:43.400
the knee is important at the top of the swing that's gonna be one of your big
245
00:21:43.400 --> 00:21:49.680
takeaways to start paying attention to when you're looking at your students leg
246
00:21:49.680 --> 00:22:06.480
action okay so we'll move on to the fourth one what's right about here okay
247
00:22:06.480 --> 00:22:13.680
so this golfer is kind of more in the middle all right so if I go back and
248
00:22:13.680 --> 00:22:24.440
replay that so this golfer here is not really a massive squat look it but it's
249
00:22:24.440 --> 00:22:28.960
not really a massive internal rotation look either all right that'll be the
250
00:22:28.960 --> 00:22:40.120
last one we'll look at there okay so if we go to this second to last one you'll
251
00:22:40.120 --> 00:22:45.400
see when the knee graph is fairly flat they got a little bit further away from
252
00:22:45.400 --> 00:22:53.000
each other and you'll see if you look at the lead ankle through transition it's
253
00:22:53.000 --> 00:23:00.960
fairly flat it's neither going massively positive or massively negative like we
254
00:23:00.960 --> 00:23:07.360
saw with the two examples of kind of the internal versus external rotation look
255
00:23:07.360 --> 00:23:12.640
so when it's flatter like that it's gonna tend to have more of the look of
256
00:23:12.640 --> 00:23:18.680
neither it's kind of in the hybrid zone but you'll see if we look at the two
257
00:23:18.680 --> 00:23:18.840
that
258
00:23:18.840 --> 00:23:23.960
are classically associated with it internal external rotation pretty much
259
00:23:23.960 --> 00:23:29.920
has the same pattern that we were seeing with the other two ABduction ADX
260
00:23:29.920 --> 00:23:38.080
you're gonna see again pretty much that mere pattern similar to what you'll see
261
00:23:38.080 --> 00:23:44.400
with internal external rotation it's just really hard to have functional pelvis
262
00:23:44.400 --> 00:23:48.760
movement and deviate too much from that pattern but you can have pretty big
263
00:23:48.760 --> 00:23:51.520
differences in what's going on with the ankles and you can have pretty big
264
00:23:51.520 --> 00:23:56.160
differences as far as what's going on with the knees you'll see that this gol
265
00:23:56.160 --> 00:23:56.320
fer
266
00:23:56.320 --> 00:24:01.040
has a interesting quirk where the trail knee stays close to the same amount of
267
00:24:01.040 --> 00:24:07.480
flex during the entire swing a little bit of straightening in the backswing but
268
00:24:07.480 --> 00:24:13.120
relatively smaller piece and valleys compared to all the other ones that we
269
00:24:13.120 --> 00:24:18.960
were looking at but you will see in that 15 to 20 degree range at the top of
270
00:24:18.960 --> 00:24:18.960
the
271
00:24:18.960 --> 00:24:24.120
swing that is one of the I'd say my big takeaways when you're looking at the
272
00:24:24.120 --> 00:24:30.520
trail leg and it's well when we get in the anatomy we'll talk about it but it's
273
00:24:30.520 --> 00:24:37.400
critical for activation okay and then he has a little bit more of the knee
274
00:24:37.400 --> 00:24:38.360
bending
275
00:24:38.360 --> 00:24:42.160
in transition before straightening but pretty pronounced straightening during
276
00:24:42.160 --> 00:24:47.600
the noun swing again not nothing too crazy there let's look at the last
277
00:24:47.600 --> 00:25:00.280
example who's got more of a strong dual external rotation look so there's a
278
00:25:00.280 --> 00:25:06.280
little bit more of a strong dual external rotation look you'll see as he's
279
00:25:06.280 --> 00:25:11.680
changing direction space between the knees is getting wider it looks like the
280
00:25:11.680 --> 00:25:16.240
knee would be pointing kind of out this way towards the camera but so it would
281
00:25:16.240 --> 00:25:19.520
look like it was going into external rotation but we know that that's not
282
00:25:19.520 --> 00:25:24.720
gonna be the case when we look at the relationship between the pelvis and the
283
00:25:24.720 --> 00:25:31.600
thigh so if you if you look at it again when you're really zoomed in like this
284
00:25:31.600 --> 00:25:36.400
you will see that the pelvis is winning the race and catching up with the thigh
285
00:25:36.400 --> 00:25:41.520
and that's pretty much what you'll see if you learn to train your eyes to see
286
00:25:41.520 --> 00:25:41.640
it
287
00:25:41.640 --> 00:25:48.400
on video as well so here's the internal external rotation that lead leg is
288
00:25:48.400 --> 00:25:48.800
going
289
00:25:48.800 --> 00:25:55.160
into internal rotation even though the knee is pointing more outward and then
290
00:25:55.160 --> 00:25:58.560
you'll see because he comes off the ground he has a fair amount of this
291
00:25:58.560 --> 00:26:04.400
little secondary dip or going into external down through impact that's where
292
00:26:04.400 --> 00:26:08.960
the foot is come off the ground so the foot is actually turning out or pivoting
293
00:26:08.960 --> 00:26:16.640
outward so the leg is going into more external rotation there and he's got a
294
00:26:16.640 --> 00:26:26.360
little bit later transition from abduction to adduction but it's still
295
00:26:26.360 --> 00:26:31.400
right around top of the swing so you can see that the knee separation is
296
00:26:31.400 --> 00:26:35.040
happening for a good amount during the downswing much further than we're seeing
297
00:26:35.040 --> 00:26:42.720
just that abduction versus adduction so we wouldn't be able to a trap a tribute
298
00:26:42.720 --> 00:26:49.720
the difference in the knee to what's going on with that lead hip but if we
299
00:26:49.720 --> 00:26:54.320
look at the ankles you'll see right around top of the swing now he's going
300
00:26:54.320 --> 00:27:02.280
into a little less than the second golfer but he's going into the supination
301
00:27:02.280 --> 00:27:08.480
pattern that's going to have a big impact in pulling the knee away and then he
302
00:27:08.480 --> 00:27:08.680
has
303
00:27:08.680 --> 00:27:13.560
again he's right around that 15 degree mark at the top of the swing and then
304
00:27:13.560 --> 00:27:17.120
flexes both knees with kind of that unweighting move before a pretty
305
00:27:17.120 --> 00:27:25.400
powerful straightening of both of the legs okay so I didn't get the video of
306
00:27:25.400 --> 00:27:32.880
the amateurs but now you'll you'll see this is a higher handicap kind of
307
00:27:32.880 --> 00:27:38.980
slicer and you'll see it's only with the high handicappers that you'll tend to
308
00:27:38.980 --> 00:27:44.680
see the possibility of the lead hip going more external and that's because
309
00:27:44.680 --> 00:27:49.080
typically with the high handicappers or occasionally with the high handicappers
310
00:27:49.080 --> 00:27:54.320
the club is changing direction before the pelvis but if you compared this to
311
00:27:54.320 --> 00:27:59.880
when the pelvis actually changes direction it's always gonna line up now
312
00:27:59.880 --> 00:28:07.360
if we look at the ankle you'll you'll tend to see he's he's got that squat
313
00:28:07.360 --> 00:28:13.240
look he's kind of looks like a you're all demonstrated real quick so he would
314
00:28:13.240 --> 00:28:18.000
look kind of more like a like a throw over the top that way so he does get a
315
00:28:18.000 --> 00:28:21.800
little bit of the widening of the shoulders but he tends to get really
316
00:28:21.800 --> 00:28:27.140
over the over the top and then have to throw the more interesting thing is if
317
00:28:27.140 --> 00:28:32.800
you look at the knee bends you'll see the trail knee is increasing flex
318
00:28:32.800 --> 00:28:33.480
increasing
319
00:28:33.480 --> 00:28:38.520
flex increasing flex increasing flex he's basically just bending and digging
320
00:28:38.520 --> 00:28:42.640
that foot into the ground and then spinning like crazy there's a lot less
321
00:28:42.640 --> 00:28:47.440
of the vertical action that we saw in more the classic pattern and you'll see
322
00:28:47.440 --> 00:28:53.880
he's got his leg bent 25 degrees at the top of the swing or maybe even more
323
00:28:53.880 --> 00:28:54.800
that's
324
00:28:54.800 --> 00:29:00.520
more than needed and we'll talk about why some golfers might have more knee
325
00:29:00.520 --> 00:29:00.800
bend
326
00:29:00.800 --> 00:29:07.800
at the top of swing than less but these two graphs especially the knee bend are
327
00:29:07.800 --> 00:29:12.680
probably more relevant at looking at lower body action than looking at either
328
00:29:12.680 --> 00:29:18.360
the hip internal external or abduction adduction and that was one of the big
329
00:29:18.360 --> 00:29:25.800
takeaways that I wanted you to take away from this 3d section now here's the
330
00:29:25.800 --> 00:29:31.800
here's another high handicap this is a golfer who gets more hooks and if we
331
00:29:31.800 --> 00:29:37.720
jump over to the knee bend graph you'll see this golfer is well below so this
332
00:29:37.720 --> 00:29:37.880
is
333
00:29:37.880 --> 00:29:40.920
a golfer who looks like he pretty much locks his leg almost looks like a
334
00:29:40.920 --> 00:29:46.400
reverse pivot at the top of the swing so I know that some golf instructors talk
335
00:29:46.400 --> 00:29:53.690
about straightening the leg as much as possible you'll see even on the the golf
336
00:29:53.690 --> 00:29:53.880
ers
337
00:29:53.880 --> 00:30:00.080
the pro golfers who straighten the leg during the backswing it will regain some
338
00:30:00.080 --> 00:30:08.520
of that flex at the top of the swing in order to use the glute properly and you
339
00:30:08.520 --> 00:30:08.600
'll
340
00:30:08.600 --> 00:30:15.080
see why when we look at the anatomy but basically in order to have the maximum
341
00:30:15.080 --> 00:30:20.280
tension through the fascia around the glute you need about 15 degrees of bend
342
00:30:20.280 --> 00:30:24.920
of the knee so neither of these two golfers are really using their their
343
00:30:24.920 --> 00:30:29.440
glutes they're tending to either use more of their back and their shoulders in
344
00:30:29.440 --> 00:30:34.960
this case or in this case he's tending to use more of his quad and his knee so
345
00:30:34.960 --> 00:30:39.760
this graph over here on the right is is quite important unfortunately I don't
346
00:30:39.760 --> 00:30:45.840
have a ton of the amateur examples because I don't have a 12 sensor I only
347
00:30:45.840 --> 00:30:51.120
have the eight but that's a very interesting graph if you as we get more
348
00:30:51.120 --> 00:30:56.680
sensor technology or if you have access to a 12 sensor or total body that one's
349
00:30:56.680 --> 00:31:04.840
pretty interesting now I've seen through through R3D on AMM I've seen an an
350
00:31:04.840 --> 00:31:12.120
average of about the trail leg straightening about eight degrees I know that I
351
00:31:12.120 --> 00:31:19.680
saw someone with gears talking about them seeing it increase three degrees and
352
00:31:19.680 --> 00:31:24.600
that could be just the difference in terms of the measurement systems I tend
353
00:31:24.600 --> 00:31:30.760
to for the body I tend to trust the electromagnetic that we use versus the
354
00:31:30.760 --> 00:31:37.520
the gears or or matter something like that but just because it's measurement
355
00:31:37.520 --> 00:31:44.520
versus projected angles I think it's a little bit more accurate but the big
356
00:31:44.520 --> 00:31:44.920
takeaway
357
00:31:44.920 --> 00:31:52.800
is if you want that look of dual external rotation then we need to get the lead
358
00:31:52.800 --> 00:31:58.120
foot to supinate in transition not pronate that will encourage some of the
359
00:31:58.120 --> 00:32:06.240
pelvis rotation without having too much of the slide but I wanted to include
360
00:32:06.240 --> 00:32:06.440
the
361
00:32:06.440 --> 00:32:09.840
knee bend graph so that we would have a smooth transition into what we're gonna
362
00:32:09.840 --> 00:32:19.680
cover next which is the anatomy okay the knee is classically described as a
363
00:32:19.680 --> 00:32:25.040
simple hinge there are but we're gonna talk about why that's maybe not the
364
00:32:25.040 --> 00:32:31.160
best description so there are three main there are three bones that make up the
365
00:32:31.160 --> 00:32:35.840
knee you've got the femur the patella or the kneecap and then the tibia or the
366
00:32:35.840 --> 00:32:42.120
shin the the shin or the lower limb also includes the fibula but that does not
367
00:32:42.120 --> 00:32:47.880
that's usually not considered part of the knee that's usually more of the ankle
368
00:32:47.880 --> 00:32:55.800
so these three bones right here now there's a bunch of muscles and we're not
369
00:32:55.800 --> 00:33:01.920
gonna cover all of them because that would be pretty hard to do and it it you
370
00:33:01.920 --> 00:33:07.200
it's probably better to just think about like okay if this is my if this is my
371
00:33:07.200 --> 00:33:13.150
thigh you almost want to divide it into four four sections so you've got kind
372
00:33:13.150 --> 00:33:13.240
of
373
00:33:13.240 --> 00:33:18.120
a top side these are your quads on the outside you have a couple smaller
374
00:33:18.120 --> 00:33:18.560
muscles
375
00:33:18.560 --> 00:33:25.600
but one really big tight band your your it band or your tractus ileo tibialis
376
00:33:25.600 --> 00:33:31.720
and then on the inside you've got your adductors these are quite important for
377
00:33:31.720 --> 00:33:37.440
golf and then on the backside here you've got your hamstring group so you've
378
00:33:37.440 --> 00:33:37.680
got
379
00:33:37.680 --> 00:33:44.560
six quads and five hamster or five sorry adductors three hamstrings and then a
380
00:33:44.560 --> 00:33:53.120
couple muscles on the side of the leg but the reason we say it's not just a
381
00:33:53.120 --> 00:33:59.160
hinge joint is the the human knee actually has all six degrees of movement now
382
00:33:59.160 --> 00:34:04.920
it tends to have very limited amount of the slide those are more micro
383
00:34:04.920 --> 00:34:05.840
movements
384
00:34:05.840 --> 00:34:13.320
but it does have a fair amount of rotation in each direction so you can
385
00:34:13.320 --> 00:34:19.960
get the the knee flexion extension going this way it just broke his leg you can
386
00:34:19.960 --> 00:34:24.880
get rotation which we'll talk about and then you can get if we're looking at it
387
00:34:24.880 --> 00:34:31.640
face-on valgus or raris or tilt and those are those are the really the
388
00:34:31.640 --> 00:34:35.920
important movement so it looks more like this you've got your flexion extension
389
00:34:35.920 --> 00:34:40.820
moving in this direction you've got valgus and varis so the leg could either
390
00:34:40.820 --> 00:34:47.120
cave in dive in or it could bow outward and then you've got rotation of the
391
00:34:47.120 --> 00:34:47.440
thigh
392
00:34:47.440 --> 00:34:53.560
and rotation of the lower limb knee rotation is the rotation of the foot or
393
00:34:53.560 --> 00:34:59.200
the lower limb compared to the upper limb so usually if the femur was fixed
394
00:34:59.200 --> 00:35:07.000
where does the foot then point okay muscle wise you've got a handful of
395
00:35:07.000 --> 00:35:14.360
muscles that bend the knee mostly your quads or sorry that mostly your
396
00:35:14.360 --> 00:35:14.720
hamstring
397
00:35:14.720 --> 00:35:19.880
group and then the extension of the knee or straightening the knee is more of
398
00:35:19.880 --> 00:35:25.880
your quad activity and then you've got medial lateral rotation this particular
399
00:35:25.880 --> 00:35:31.680
slide doesn't talk about the valgus varis but basically if we go back to this
400
00:35:31.680 --> 00:35:38.640
slide the ones that pull the knee more into valgus would be the inside of the
401
00:35:38.640 --> 00:35:45.680
thigh or the adductors and the ones that pull it into sorry that pull it into
402
00:35:45.680 --> 00:35:49.720
valgus would be the outside of the leg which would pull the knee inward or the
403
00:35:49.720 --> 00:35:57.320
one that pulls it into varis would be more the inside of the leg now as a golf
404
00:35:57.320 --> 00:36:02.520
instructor you don't have to know the detailed anatomy but it's good to be
405
00:36:02.520 --> 00:36:07.360
able to understand when a golfer talks to you about either having an MCL issue
406
00:36:07.360 --> 00:36:13.440
or having a meniscus surgery this is this is what they're talking about so
407
00:36:13.440 --> 00:36:18.520
you've got your the patella has been removed so it's easier to see or actually
408
00:36:18.520 --> 00:36:24.760
we're looking at it from the yeah the front side of the right knee because of
409
00:36:24.760 --> 00:36:32.880
where the fibio's so the meniscus are these two little kind of horseshoe shaped
410
00:36:32.880 --> 00:36:39.280
cartilage enclosures and what they do if you look from the top down they're
411
00:36:39.280 --> 00:36:46.800
almost like like extra cushioning and so when you're when you're the ball of
412
00:36:46.800 --> 00:36:47.080
the
413
00:36:47.080 --> 00:36:51.080
femur is sitting in there they kind of cup it so then if I start to push on the
414
00:36:51.080 --> 00:36:55.640
side instead of having nothing to stop me from sliding there's a little bit of
415
00:36:55.640 --> 00:37:00.880
an edge there that edge when I push down into it increases the surface area so
416
00:37:00.880 --> 00:37:07.520
then I don't create quite as much stress on one particular area but when your
417
00:37:07.520 --> 00:37:12.680
golfer is talking about either I had a medial meniscus tear that would be this
418
00:37:12.680 --> 00:37:17.480
half over here or a lateral meniscus tear that would be over here and then
419
00:37:17.480 --> 00:37:21.240
anterior would be towards the front of the body or posterior would be towards
420
00:37:21.240 --> 00:37:25.520
the back of the body and typically what'll happen is the movement opposite to
421
00:37:25.520 --> 00:37:31.630
where the terrors will cause pain so when when we're looking at it like this
422
00:37:31.630 --> 00:37:32.600
you
423
00:37:32.600 --> 00:37:38.640
can imagine if the if the thigh was to say was gonna push towards the front or
424
00:37:38.640 --> 00:37:43.960
towards the camera this way then it would increase the pressure in this
425
00:37:43.960 --> 00:37:50.040
cartilage entrapment in the backside and vice versa so it's almost like a disc
426
00:37:50.040 --> 00:37:56.510
where it when you push one direction the pressure builds up on the other side
427
00:37:56.510 --> 00:37:57.600
now
428
00:37:57.600 --> 00:38:03.040
so that's the meniscus the other key component to the knee is looking at these
429
00:38:03.040 --> 00:38:07.800
ligaments and they basically act like like string or plastic that hold it
430
00:38:07.800 --> 00:38:13.760
together so you could see if I was to bow the leg out like this then this side
431
00:38:13.760 --> 00:38:18.360
here this that would be connecting these two so where my thumbs are that would
432
00:38:18.360 --> 00:38:22.760
be placed under tension or stress and if I went this way between the pinky side
433
00:38:22.760 --> 00:38:27.880
would be placed under tension or stress so for most knee injuries if you can
434
00:38:27.880 --> 00:38:32.320
keep the knee more in neutral especially when you're pushing vertically pushing
435
00:38:32.320 --> 00:38:36.760
a lot of force through it it's going to tend to be better for the overall
436
00:38:36.760 --> 00:38:44.880
structure so here's another picture just kind of showing the little sponge
437
00:38:44.880 --> 00:38:45.840
those
438
00:38:45.840 --> 00:38:50.360
meniscus in between and then here you can get a little better view of the ACL
439
00:38:50.360 --> 00:38:59.520
and the the PCL so you've got the medial MCL and then the lateral and then the
440
00:38:59.520 --> 00:39:03.560
anterior and posterior cruciate ligament which means crosses and they
441
00:39:03.560 --> 00:39:08.240
basically kind of look like this so if you take your middle finger and cross
442
00:39:08.240 --> 00:39:14.360
it over your front finger and then you put that up against your knee so the ACL
443
00:39:14.360 --> 00:39:19.280
is on top it goes from the outside across this way and then the PCL goes
444
00:39:19.280 --> 00:39:24.560
more runs it a direction more towards the outside of the leg like that and
445
00:39:24.560 --> 00:39:32.080
basically when they get stressed that's when they can potentially tear or cause
446
00:39:32.080 --> 00:39:38.880
injuries so for example this is the test for assessing the ACL so the ACL
447
00:39:38.880 --> 00:39:45.160
coming across like this if I if I pull the bottom further away from the top
448
00:39:45.160 --> 00:39:50.440
that's gonna lengthen that ligament and so if that ligament is damaged I'll be
449
00:39:50.440 --> 00:39:57.040
able to pull this more than I should be able to so when your golfers have
450
00:39:57.040 --> 00:40:02.120
ligament issues they can tend to cause really sharp pains and they'll tend to
451
00:40:02.120 --> 00:40:06.840
kind of like come out of I don't want to say come out of nowhere but it's like
452
00:40:06.840 --> 00:40:10.280
everything's fine everything's fine and then oh man I heard a lot and then it
453
00:40:10.280 --> 00:40:18.000
either lingers or goes away but it kind of comes out of nowhere so the most
454
00:40:18.000 --> 00:40:23.600
important part of that we'll cover here in a section or in a second so how that
455
00:40:23.600 --> 00:40:30.640
applies to the golf swing in the golfers you're gonna be working with and how
456
00:40:30.640 --> 00:40:35.760
that relates to some of those three graphs that we looked at okay so now we
457
00:40:35.760 --> 00:40:42.000
get back to these core movements and looking at the relationship of these the
458
00:40:42.000 --> 00:40:48.000
cool thing about the knee is it's a good way of looking at the movement of a
459
00:40:48.000 --> 00:40:54.880
whole lower limb got a slide here coming up in a bit that will help tie that in
460
00:40:54.880 --> 00:40:59.440
together but there are related movements of what will happen at the hip and
461
00:40:59.440 --> 00:40:59.640
what
462
00:40:59.640 --> 00:41:04.200
will happen at the ankle and the knee in the middle if you see the movement
463
00:41:04.200 --> 00:41:04.440
going
464
00:41:04.440 --> 00:41:07.240
in one direction or the other that can kind of give you a sense of what's
465
00:41:07.240 --> 00:41:11.570
happening at either the ankle or the hip or help out with that but these are
466
00:41:11.570 --> 00:41:11.640
the
467
00:41:11.640 --> 00:41:17.080
classic movements flexion extension valgus verus or abduction
468
00:41:17.080 --> 00:41:25.720
adduction and then internal external rotation of the tibia now the cool thing
469
00:41:25.720 --> 00:41:33.000
about the knee this is part of the reason why so the knee is not a hinge in any
470
00:41:33.000 --> 00:41:38.560
sense of the way more you know your elbow is close to a hinge it pretty much
471
00:41:38.560 --> 00:41:43.800
moves exclusively in this direction the knee has rotation and the side bending
472
00:41:43.800 --> 00:41:50.200
and when it does hinge this slide here is the show that it's not actually like
473
00:41:50.200 --> 00:41:50.240
a
474
00:41:50.240 --> 00:41:54.640
hinge like this there's actually a sliding movement now one of the
475
00:41:54.640 --> 00:41:58.960
questions about the knee was what happens when you get a knee replacement
476
00:41:58.960 --> 00:42:06.760
typically that sliding movement goes away so the instead of it sliding as it
477
00:42:06.760 --> 00:42:13.560
pivots like this it will now just kind of become more of a hinge so while there
478
00:42:13.560 --> 00:42:18.360
aren't too many contraindications for golf some of the movement patterns can
479
00:42:18.360 --> 00:42:23.280
change a little bit and golfers might not feel quite as comfortable with it
480
00:42:23.280 --> 00:42:30.360
that's usually the bigger thing that you have to address looking at so this is
481
00:42:30.360 --> 00:42:35.480
the extension when it moves in the opposite direction so as the bone slides
482
00:42:35.480 --> 00:42:42.920
this way it rolls that way so as it slides posterior it rolls anterior or
483
00:42:42.920 --> 00:42:50.820
basically this is what's happening when the leg is going into extension now we
484
00:42:50.820 --> 00:42:57.040
made it look pretty simple when we looked at the bone but those two called
485
00:42:57.040 --> 00:43:02.320
condyles the the surface area for how the the knee bones fit together are not
486
00:43:02.320 --> 00:43:08.480
symmetrical so they're on a little bit of an angle and one of them is bigger
487
00:43:08.480 --> 00:43:14.000
than the other so this the joint is designed to kind of flex the knee pretty
488
00:43:14.000 --> 00:43:19.200
straight but imagine trying to drive a car straight if you had a car that had
489
00:43:19.200 --> 00:43:25.720
one small wheel and one big wheel so it kind of has to regulate these two the
490
00:43:25.720 --> 00:43:34.920
the rates that they turn and the the surface on the bottom is pretty flat but
491
00:43:34.920 --> 00:43:39.680
the surface or the axis of rotation as you see from this little truncated cone
492
00:43:39.680 --> 00:43:45.320
becomes a little bit of an angle so as a result you actually get a little bit
493
00:43:45.320 --> 00:43:45.440
of
494
00:43:45.440 --> 00:43:52.080
rotation with bending and straightening the leg classically when you straighten
495
00:43:52.080 --> 00:43:58.400
the leg in order to lock it out the foot will actually at the end the last 20
496
00:43:58.400 --> 00:44:03.360
degrees which in this position I can't actually get into when you lock out the
497
00:44:03.360 --> 00:44:08.040
leg it will go into external rotation and then when you flex the leg it will go
498
00:44:08.040 --> 00:44:14.440
into internal rotation so that's why when you see someone walking that foot
499
00:44:14.440 --> 00:44:15.520
will
500
00:44:15.520 --> 00:44:21.720
tend to swing out behind and out to the side just a little bit that's the
501
00:44:21.720 --> 00:44:23.120
natural
502
00:44:23.120 --> 00:44:28.880
internal rotation associated with flexion of the knee so the interesting
503
00:44:28.880 --> 00:44:32.840
thing is when the knee is more flexed it has more range of motion rotationally
504
00:44:32.840 --> 00:44:37.000
when you straighten it it tends to lock in place so that you don't have to use
505
00:44:37.000 --> 00:44:40.640
your muscles to hold yourself up if you're standing for a long period of time
506
00:44:40.640 --> 00:44:46.440
now where that comes in is if you were to totally straighten the leg you would
507
00:44:46.440 --> 00:44:53.110
lose a significant amount of rotation at the knee so I know some golf
508
00:44:53.110 --> 00:44:53.560
instructors
509
00:44:53.560 --> 00:44:58.560
advocate fully straightening the leg or trying to straighten the leg but there
510
00:44:58.560 --> 00:45:02.640
is a point where you get past that 20 degree mark and now you start to lose
511
00:45:02.640 --> 00:45:07.640
rotation it's rotation of the knee and not the hip or the pelvis but it's still
512
00:45:07.640 --> 00:45:11.920
losing rotation so you don't want to advocate straightening the leg past that
513
00:45:11.920 --> 00:45:19.200
15 20 degree mark the other piece we'll get to here in a second so this was a
514
00:45:19.200 --> 00:45:24.000
interesting slide I just thought you could kind of it would help you envision
515
00:45:24.000 --> 00:45:28.280
why the knee has its shape and look the way that it does it's almost like a
516
00:45:28.280 --> 00:45:33.440
column where instead of having two poles sitting on top like this you've got a
517
00:45:33.440 --> 00:45:38.240
much broader surface area so for a structure that has to actually support
518
00:45:38.240 --> 00:45:42.560
a fair amount of weight they made it wider at the connection point so that
519
00:45:42.560 --> 00:45:48.080
you have greater surface area and the the bone actually has these almost like
520
00:45:48.080 --> 00:45:53.800
rebar in concrete and those need to line up that's how force goes through in
521
00:45:53.800 --> 00:45:53.920
the
522
00:45:53.920 --> 00:46:00.800
most kind of economical way so if you if your knee is caved in or out or
523
00:46:00.800 --> 00:46:04.800
rotated those things don't line up and you start to get where and you start to
524
00:46:04.800 --> 00:46:13.200
get arthritis building up so that there's a couple different angles that are
525
00:46:13.200 --> 00:46:13.440
key
526
00:46:13.440 --> 00:46:20.160
to looking at the lower limb typically the hip will hopefully be on about a
527
00:46:20.160 --> 00:46:26.240
three degree angle but the axis of the knee whoops the axis will go pretty much
528
00:46:26.240 --> 00:46:30.160
through the second toe through the knee through the hip joint like that so you
529
00:46:30.160 --> 00:46:30.160
've
530
00:46:30.160 --> 00:46:35.840
got the angle of the tibia and then you've got the angle of the femur but the
531
00:46:35.840 --> 00:46:40.450
relationship that you really want to look at is the second toe to the knee to
532
00:46:40.450 --> 00:46:40.560
the
533
00:46:40.560 --> 00:46:45.640
hip so this would be a case of a kind of knock knee this would be bow leg in
534
00:46:45.640 --> 00:46:45.920
both
535
00:46:45.920 --> 00:46:53.280
cases you can see that that force is going to be either too much on the inside
536
00:46:53.280 --> 00:46:59.320
there or too much on the outside based on the position and the tension being a
537
00:46:59.320 --> 00:47:07.680
little bit off so this is probably the most important slide for practically
538
00:47:07.680 --> 00:47:13.680
applying what's going on with the with the knee so if the knee caves in the
539
00:47:13.680 --> 00:47:13.960
foot
540
00:47:13.960 --> 00:47:20.120
will roll in the pelvis will tip forward if the knee bows out then the foot
541
00:47:20.120 --> 00:47:20.440
will
542
00:47:20.440 --> 00:47:26.280
roll outward or supinate and the pelvis will tilt backward so the knee can give
543
00:47:26.280 --> 00:47:30.240
you a really good sense of what's happening with the ankle and help you
544
00:47:30.240 --> 00:47:35.360
see what's happening with the pelvis more so if you look at them when they're
545
00:47:35.360 --> 00:47:39.280
at your golfers when they're just kind of walking and standing casually you'll
546
00:47:39.280 --> 00:47:45.790
see what kind of bias they're personal you know their normal stance is
547
00:47:45.790 --> 00:47:46.640
presenting
548
00:47:46.640 --> 00:47:59.240
all right we'll keep moving on this is where the knee becomes really critical
549
00:47:59.240 --> 00:47:59.360
for
550
00:47:59.360 --> 00:48:05.600
what's going on with the hip so this is a picture to show the glute fascia so
551
00:48:05.600 --> 00:48:09.080
your glute has two different parts the superficial and the deep and the
552
00:48:09.080 --> 00:48:16.120
superficial part goes through this it band or tractus elio tibialis and it
553
00:48:16.120 --> 00:48:21.480
connects down below the knee so the attachment for your glute the attachment
554
00:48:21.480 --> 00:48:27.040
for your biggest hip muscle your biggest rotator is below the knee it's not way
555
00:48:27.040 --> 00:48:32.520
up here where you might think and so you can you can feel it on yourself if
556
00:48:32.520 --> 00:48:38.520
you if you can relax the leg and you just put your hand on the side there's a
557
00:48:38.520 --> 00:48:43.240
little band here that's your IT band if you put it there as you raise it up you
558
00:48:43.240 --> 00:48:43.320
'll
559
00:48:43.320 --> 00:48:47.720
feel that the tension in that band changes and if you bring it all the way
560
00:48:47.720 --> 00:48:52.040
down you'll feel that that tension actually slacks unless you're like
561
00:48:52.040 --> 00:48:55.480
locking the leg and you're actually feeling one of your quad muscles if you
562
00:48:55.480 --> 00:48:59.640
can keep the leg pretty relaxed you can feel the tension in the band change so
563
00:48:59.640 --> 00:49:06.120
if you what you'll see is that first golfer that first amateur golfer who
564
00:49:06.120 --> 00:49:09.960
was keeping a lot of knee tension they weren't really using their glutes
565
00:49:09.960 --> 00:49:10.760
because
566
00:49:10.760 --> 00:49:15.720
they were bending their knee so much that they were loading more into the quad
567
00:49:15.720 --> 00:49:15.960
or
568
00:49:15.960 --> 00:49:20.800
the front of the leg or the you know the top of the way the second golfer who
569
00:49:20.800 --> 00:49:26.040
straightened the leg so much that now this lost slack he's not using his legs
570
00:49:26.040 --> 00:49:30.320
actually at all he's using more of a really big upper body power source and
571
00:49:30.320 --> 00:49:36.240
just getting that into a longer position to create tension all the way up for
572
00:49:36.240 --> 00:49:40.520
the upper body not so much the hip and the lower body but this is one of the
573
00:49:40.520 --> 00:49:46.880
most important relationships that you'll see which is the foregolf especially
574
00:49:46.880 --> 00:49:47.040
for
575
00:49:47.040 --> 00:49:52.600
that right leg if you're gonna try to use the the glutes then you want that leg
576
00:49:52.600 --> 00:49:57.560
to have or that knee to have at least 15 degrees of bend and if you want the
577
00:49:57.560 --> 00:50:03.320
knee to be able to rotate then you want it to have let's say 20 degrees of or
578
00:50:03.320 --> 00:50:03.740
or
579
00:50:03.740 --> 00:50:09.230
more bend so if you're somewhere in that 15 to 20 degree range which is where
580
00:50:09.230 --> 00:50:09.320
we
581
00:50:09.320 --> 00:50:15.040
saw all the pros then your hip and your knee will be able to function to the
582
00:50:15.040 --> 00:50:15.200
best
583
00:50:15.200 --> 00:50:21.600
of their capabilities so if I slide come back to this but if I jump back up if
584
00:50:21.600 --> 00:50:21.720
we
585
00:50:21.720 --> 00:50:27.280
look at this graph over here the green line is that trail hip or that sorry
586
00:50:27.280 --> 00:50:31.720
that trail knee and you'll see every golfer has a little different way of
587
00:50:31.720 --> 00:50:37.240
getting to that 15 to 20 degree number so here's someone who pretty much locks
588
00:50:37.240 --> 00:50:41.560
the leg but then bends it and right around change direction it's in that
589
00:50:41.560 --> 00:50:47.080
right zone here's someone who straightens it bends it straightens it and then
590
00:50:47.080 --> 00:50:54.160
it's in that 15 20 degree zone you'll tend to see you'll this is one of those
591
00:50:54.160 --> 00:50:57.260
patterns you'll see very few outliers but you'll see very different ways of
592
00:50:57.260 --> 00:51:01.880
getting there some bend it or some straighten it a lot some straighten it a
593
00:51:01.880 --> 00:51:07.640
little some straighten it or straighten it consistently to the top of the swing
594
00:51:07.640 --> 00:51:13.240
other is straighten it then bend it to get back to that number but you'll see
595
00:51:13.240 --> 00:51:19.240
that number because of its relationship with the hip and the glute is a key one
596
00:51:19.240 --> 00:51:24.840
to try to aspire to and you'll see amateurs miss that mark by pretty huge
597
00:51:24.840 --> 00:51:32.740
factors so I thought that would be an interesting piece for you guys to take
598
00:51:32.740 --> 00:51:39.060
away from this discussion on the knee because you'll see that if we went back
599
00:51:39.060 --> 00:51:43.060
and looked at the anatomy you'll see that a lot of the key muscles that work
600
00:51:43.060 --> 00:51:50.420
around the knee connect way up here by on the pelvis and so most of the muscles
601
00:51:50.420 --> 00:51:56.920
that cross the knee joint have pretty strong long levers and so the knee can
602
00:51:56.920 --> 00:52:03.380
give you a good sense of what's happening with the with the hip if the
603
00:52:03.380 --> 00:52:09.200
knee is going outward there's a good chance that the pelvis is tipping
604
00:52:09.200 --> 00:52:13.040
backward if the knee is going inward there's a good chance the pelvis is
605
00:52:13.040 --> 00:52:18.000
tipping forward there's lots of these really cool relationships between the
606
00:52:18.000 --> 00:52:24.340
two but maybe we'll do that in a second you know talk about the knee somewhere
607
00:52:24.340 --> 00:52:28.920
down the road the main goals today was to understand the basic structure and
608
00:52:28.920 --> 00:52:33.640
some of the basic relationships and start looking at it in its alignment
609
00:52:33.640 --> 00:52:39.740
between the ankle and the knee or sorry the ankle and the hip now one last
610
00:52:39.740 --> 00:52:39.920
piece
611
00:52:39.920 --> 00:52:46.960
that I wanted to address was if I go back to this running slide we are best at
612
00:52:46.960 --> 00:52:53.000
pushing force vertically when the knee and the actually forget vertically we're
613
00:52:53.000 --> 00:52:57.760
best at pushing force when the hip and the knee and the ankle are in a very
614
00:52:57.760 --> 00:53:04.080
straight line so if your golfer is getting into a position like let's say
615
00:53:04.080 --> 00:53:08.920
this was a left hand golfer and here was the top or here was the transition
616
00:53:08.920 --> 00:53:13.760
position you could see that if they were to push a lot with that lead leg with
617
00:53:13.760 --> 00:53:19.360
the knee kicked in like that they would slowly erode the inside of the leg or
618
00:53:19.360 --> 00:53:26.120
the posterior left meniscus same thing here if you see a golfer sliding like
619
00:53:26.120 --> 00:53:30.480
this they they won't be able to push vertically very well through the leg
620
00:53:30.480 --> 00:53:38.280
because the knee is out of alignment so what should happen if I back up is that
621
00:53:38.280 --> 00:53:43.360
basically when I go to the top of the swing I want to have in my right leg
622
00:53:43.360 --> 00:53:43.600
which
623
00:53:43.600 --> 00:53:49.240
is this one over here I want to have a pretty straight line of force from my
624
00:53:49.240 --> 00:53:49.480
hip
625
00:53:49.480 --> 00:53:53.280
which is right around here through the knee through kind of gyps so I have to
626
00:53:53.280 --> 00:53:58.120
make sure the knee too far outside or they tend to slide into that knee because
627
00:53:58.120 --> 00:54:05.520
the ankle was pronating a lot and now they're pushing more on the inside of
628
00:54:05.520 --> 00:54:12.160
the ankle and the outside of the knee so that's a hard one to let's say coach
629
00:54:12.160 --> 00:54:12.440
as
630
00:54:12.440 --> 00:54:18.040
far as like feeling exactly where your knee is that's where good gym exercises
631
00:54:18.040 --> 00:54:23.800
or stability training or lower body awareness and learning how to keep that
632
00:54:23.800 --> 00:54:28.560
alignment is probably easier but that is something to watch out for especially
633
00:54:28.560 --> 00:54:28.680
if
634
00:54:28.680 --> 00:54:33.720
your students are complaining about knee pain that possibly in that case you
635
00:54:33.720 --> 00:54:38.720
might have to do some spatial awareness and help them get the knee in a little
636
00:54:38.720 --> 00:54:47.960
bit better line with the ankle and the hip okay as far as knee replacements go
637
00:54:47.960 --> 00:54:52.760
this is actually pretty easy because the knee is not really a contraindication
638
00:54:52.760 --> 00:54:53.360
for
639
00:54:53.360 --> 00:54:58.880
golf the the three main things that they'll warn you about doing with a knee
640
00:54:58.880 --> 00:55:04.480
replacement like two-thirds of the population of people who get knee
641
00:55:04.480 --> 00:55:10.240
replacements complain of pain with deep flexion and some of especially the
642
00:55:10.240 --> 00:55:16.240
older knee replacement models they would say don't bend your knee passed I
643
00:55:16.240 --> 00:55:21.640
forget if it was 40 degrees or but basically don't do a deep squat don't
644
00:55:21.640 --> 00:55:26.040
bend all the way the knee is there the replacement wasn't able to handle that
645
00:55:26.040 --> 00:55:29.720
we don't get into that position in golf so that's not really an issue for us
646
00:55:29.720 --> 00:55:36.680
at all number two was impact so like sports like with a lot of running jumping
647
00:55:36.680 --> 00:55:42.440
things like that were contraindicated but they would usually say that jogging
648
00:55:42.440 --> 00:55:42.600
or
649
00:55:42.600 --> 00:55:49.280
brisk walking was fine if you look at Sasha's work the the amount of pressure
650
00:55:49.280 --> 00:55:54.720
through that lead knee is closer to one and a half of times your body weight
651
00:55:54.720 --> 00:56:01.920
which is about the same as jogging so it's not really a a deep impact or
652
00:56:01.920 --> 00:56:08.440
compressive force issue when it comes to the knee quick torsion is the the last
653
00:56:08.440 --> 00:56:13.480
contraindication which is basically like watch quick changes direction that's
654
00:56:13.480 --> 00:56:17.040
the one that you might have to be careful about especially if they have a
655
00:56:17.040 --> 00:56:22.880
transition pattern where they get the knee out of that line of hip ankle knee
656
00:56:22.880 --> 00:56:24.360
but
657
00:56:24.360 --> 00:56:27.840
in general it's going to be slow enough that it shouldn't cause too much
658
00:56:27.840 --> 00:56:34.600
problems now that being said we have to be careful with is if they had a knee
659
00:56:34.600 --> 00:56:39.520
replacement unless there was a trauma there's a very good chance that the knee
660
00:56:39.520 --> 00:56:44.760
took the beating from either a faulty moving ankle or a faulty moving hip and
661
00:56:44.760 --> 00:56:49.920
so whenever I see whenever someone tells me they had a knee injury I want to
662
00:56:49.920 --> 00:56:50.120
look
663
00:56:50.120 --> 00:56:53.820
at how the knee is moving or sorry how the hip is moving and how the ankle is
664
00:56:53.820 --> 00:56:57.760
moving because that's probably going to have a bigger impact on my coaching
665
00:56:57.760 --> 00:56:58.720
cues
666
00:56:58.720 --> 00:57:04.520
the other thing is if it was a relatively new surgery while the knee is still
667
00:57:04.520 --> 00:57:08.840
able to function it's going to feel different and it's not going to have the
668
00:57:08.840 --> 00:57:16.360
same slide they may have some clicks or you know it may not feel quite as
669
00:57:16.360 --> 00:57:21.080
comfortable and so as a result they may be tentative and not want to use their
670
00:57:21.080 --> 00:57:25.720
lower body but I've never had any any doctors that I've talked to say that
671
00:57:25.720 --> 00:57:31.040
there is like a contraindication for swinging golf club so it's usually just
672
00:57:31.040 --> 00:57:37.360
working around the psychology of what your your student is kind of having
673
00:57:37.360 --> 00:57:37.680
trouble
674
00:57:37.680 --> 00:57:44.760
with and they may have a little bit like I said trouble getting quicker ankle
675
00:57:44.760 --> 00:57:52.280
movements because of the knee so you may have to be a little bit less explosive
676
00:57:52.280 --> 00:57:55.760
with the lower body and a little bit more from your core and shoulders but I
677
00:57:55.760 --> 00:58:02.320
haven't had a need to make major changes for anyone facing knee replacement or
678
00:58:02.320 --> 00:58:08.320
who's who've successfully had a knee replacement surgery
679
00:58:08.320 --> 00:58:17.480
okay so if you have any questions please type them in the chat like I said I've
680
00:58:17.480 --> 00:58:23.720
got a one question and then a couple swings that we'll take a look at and I've
681
00:58:23.720 --> 00:58:31.480
got one ulnar deviation case study that I brought in for today so this leads
682
00:58:31.480 --> 00:58:37.320
towards one of the ideas that I'll have either next webinar or the following
683
00:58:37.320 --> 00:58:38.240
but
684
00:58:38.240 --> 00:58:41.200
the question was basically looking at the wrist that's one of the hottest
685
00:58:41.200 --> 00:58:45.680
topics though in transition do we want the lead risk going into ulnar straight
686
00:58:45.680 --> 00:58:51.560
away do you see most guys have very little addition and radial at the
687
00:58:51.560 --> 00:59:00.640
start down I'd say the majority of Torpros will have it'll stay close to the
688
00:59:00.640 --> 00:59:06.080
same you'll have a real slight ulnar deviation happening in transition but
689
00:59:06.080 --> 00:59:10.760
there is you know a good a small I shouldn't say good percentage but there's
690
00:59:10.760 --> 00:59:16.280
a percentage I don't know if it's 25 percent or 10 percent or what but guys
691
00:59:16.280 --> 00:59:23.120
who rehinge it and then start going out of it later so they rehinge it until
692
00:59:23.120 --> 00:59:26.440
about vertical as they're kind of pulling down and creating more power
693
00:59:26.440 --> 00:59:33.360
with the arms and then they start going into the ulnar deviation later so I
694
00:59:33.360 --> 00:59:40.000
typically focus more on the feeling of getting it right there unless they're
695
00:59:40.000 --> 00:59:46.560
really late the when I see on video we'll see it with the case study when I see
696
00:59:46.560 --> 00:59:51.280
on video a golfer where the wrist look like they stayed the same between about
697
00:59:51.280 --> 00:59:57.760
there and there I know we're gonna be battling some steep diggy wrist movement
698
00:59:57.760 --> 01:00:04.920
and so I usually look at it more as like at least by belly button height or
699
01:00:04.920 --> 01:00:09.200
delivery position I want to make sure that the wrist are coming out for some
700
01:00:09.200 --> 01:00:13.120
golfers they're very unaware of where the club is at the top of the swing and
701
01:00:13.120 --> 01:00:18.360
they need to start feeling it go that way much earlier but we'll probably do
702
01:00:18.360 --> 01:00:22.240
that it will probably look at actual 3D of the wrist look at details of the
703
01:00:22.240 --> 01:00:29.080
motorcycle and ulnar deviation in transition at some point here we'll come
704
01:00:29.080 --> 01:00:38.120
to that okay so here was a case study I had you know read the book came in for
705
01:00:38.120 --> 01:00:43.760
a for a lesson and I thought it'd be a good kind of practical application of
706
01:00:43.760 --> 01:00:57.560
that let's mute that okay so if I kind of scrub through you'll see as he starts
707
01:00:57.560 --> 01:01:05.840
down it's a fair but pretty good looking save from it so steep contact or steep
708
01:01:05.840 --> 01:01:10.280
position but the body is not in a very steep position so it had to be coming
709
01:01:10.280 --> 01:01:16.560
from the arms we talked a little bit about having that much radio deviation
710
01:01:16.560 --> 01:01:23.120
or hinge that late in the swing so then we did just a couple couple drills to
711
01:01:23.120 --> 01:01:27.520
work on getting this sense of feeling more of the ulnar deviation and you can
712
01:01:27.520 --> 01:01:37.160
see how his preset move is basically it's shallower and you can the the hook
713
01:01:37.160 --> 01:01:47.600
became much harder for him to accomplish so there's kind of his little let's do
714
01:01:47.600 --> 01:01:52.600
yeah it plays a little too fast okay so his preset move was really getting that
715
01:01:52.600 --> 01:02:01.320
ulnar deviation early and so you'll see now what's common what we'll probably
716
01:02:01.320 --> 01:02:07.000
have to work through next time is you'll notice that golfers who love to retain
717
01:02:07.000 --> 01:02:10.720
that radial deviation for a long period of time will typically try to shallow
718
01:02:10.720 --> 01:02:10.880
it
719
01:02:10.880 --> 01:02:18.400
more by be creating arm depth instead of that ulnar deviation but he is ulnar
720
01:02:18.400 --> 01:02:26.320
deviating now through there where if we look at originally
721
01:02:26.320 --> 01:02:32.680
bring it back not yet not yet not yet right around there right around that
722
01:02:32.680 --> 01:02:36.960
frame is kind of where he starts that ulnar deviation so we've now got it
723
01:02:36.960 --> 01:02:44.240
probably 20 30% whoops earlier which I would consider better in this particular
724
01:02:44.240 --> 01:02:51.280
movement and it will certainly help with shallowing out the bottom of the swing
725
01:02:51.280 --> 01:02:56.000
and you'll notice on the way through if you were astute you'll see that he has
726
01:02:56.000 --> 01:03:05.000
less of the stand-up move compared to where he started and so that stand-up
727
01:03:05.000 --> 01:03:10.960
move will tend to cause more of that pull hook so this was moving us in the
728
01:03:10.960 --> 01:03:20.520
right direction okay I see Craig just joined perfect because we're about to
729
01:03:20.520 --> 01:03:26.600
talk about your student and this is this is probably one of the toughest case
730
01:03:26.600 --> 01:03:32.280
studies or swing consultation questions I've gotten here so he's got a student
731
01:03:32.280 --> 01:03:36.800
who has left hemispheric cerebral palsy he was supposed to never get out of a
732
01:03:36.800 --> 01:03:41.120
wheelchair when he was born obviously he's better than that you'll see he has a
733
01:03:41.120 --> 01:03:47.120
brace on his left leg is a and I'm glad to see you on here Craig is the brace
734
01:03:47.120 --> 01:03:47.360
in
735
01:03:47.360 --> 01:03:52.800
the ankle or on the knee if you get a chance and he uses neoprene wrap on his
736
01:03:52.800 --> 01:03:58.290
left hand I assume to help stabilize the wrist he cannot process information
737
01:03:58.290 --> 01:03:58.640
when
738
01:03:58.640 --> 01:04:02.880
you talk into his left ear he needs visual problems with the left eye so he
739
01:04:02.880 --> 01:04:07.360
tends to line everything left of target would like some advice on what drills
740
01:04:07.360 --> 01:04:20.640
and ideas to help his game so let's zoom it in here
741
01:04:20.640 --> 01:04:27.200
oh whoops you guys can't see what I'm looking at can you
742
01:04:32.880 --> 01:04:42.320
okay so I know you can't see the mouse on this but
743
01:04:42.320 --> 01:04:49.640
thanks ankle perfect okay that's what it looked like but I wasn't quite sure
744
01:04:49.640 --> 01:04:51.440
okay
745
01:04:51.440 --> 01:05:01.960
so we I think you've done a tremendous job with this golf swing with all those
746
01:05:01.960 --> 01:05:09.320
limitations I mean you can see the the left wrist is pretty much bandaged up
747
01:05:09.320 --> 01:05:18.360
so the you know some whenever I'm looking at kind of a let's say a quirky
748
01:05:18.360 --> 01:05:23.080
or swing I'm looking at kind of well what's the if I could change one movement
749
01:05:23.080 --> 01:05:23.240
or
750
01:05:23.240 --> 01:05:32.680
one position what would I go after this swing to me I would use
751
01:05:32.680 --> 01:05:41.480
peterson I'm drawing a blank on his carl carl peterson I would use him as the
752
01:05:41.480 --> 01:05:48.200
model because I think that he's doing a great job of mimicking some of his
753
01:05:48.200 --> 01:05:54.280
transition moves where his body gets pretty open and out I would probably
754
01:05:54.280 --> 01:06:00.680
work on if I was trying to get into a little bit better
755
01:06:00.680 --> 01:06:07.320
bracing position I would try to get the club shallowing just a touch more there
756
01:06:07.320 --> 01:06:14.360
so that then potentially he could he could go into a little bit more bracing
757
01:06:14.360 --> 01:06:14.520
but the
758
01:06:14.520 --> 01:06:20.440
hard thing here is most of the bracing typically comes through that left leg
759
01:06:20.440 --> 01:06:26.520
and I'm not quite sure what he'll be able to do with that left ankle you'll
760
01:06:26.520 --> 01:06:33.480
see that the whole the whole lower unit basically pivots and moves like so and
761
01:06:33.480 --> 01:06:40.920
he's actually pivoting more around that right leg right the left leg the left
762
01:06:40.920 --> 01:06:41.240
leg
763
01:06:41.240 --> 01:06:47.880
is more passive in this case and where he's getting that right arm is
764
01:06:47.880 --> 01:06:54.120
quite good you know he's got a decent white movement where that right arm is
765
01:06:54.120 --> 01:07:02.440
actually working across that body it's you've done a really good job with
766
01:07:02.440 --> 01:07:07.640
building a lot of the key core pieces but one of my overriding philosophies is
767
01:07:07.640 --> 01:07:11.880
that if any golfer comes in I should be able to help them improve
768
01:07:11.880 --> 01:07:15.560
the energy you know the way that they're swinging the club
769
01:07:15.560 --> 01:07:24.040
so with him I would try and experiment with a little bit more um bracing
770
01:07:24.040 --> 01:07:31.320
so you know the bracing drill where basically I go and and pull on the club
771
01:07:31.320 --> 01:07:35.320
the danger you would have to you'd have to make sure that he turned his head so
772
01:07:35.320 --> 01:07:35.480
that he
773
01:07:35.480 --> 01:07:39.320
could hear from the right right side and see it with the right side
774
01:07:39.320 --> 01:07:47.160
and I just want to I'd do it very gently and I'd see if he was feeling it more
775
01:07:47.160 --> 01:07:47.320
in
776
01:07:47.320 --> 01:07:54.200
the left leg or if he was feeling it more in the right leg because I would I
777
01:07:54.200 --> 01:07:59.720
would tend to bet that he he's a decent driver of the golf ball and would
778
01:08:00.280 --> 01:08:07.720
struggle or complain more about low point control with his scoring irons yeah
779
01:08:07.720 --> 01:08:15.480
so you could potentially work on getting just a little bit earlier or more
780
01:08:15.480 --> 01:08:16.120
shallow
781
01:08:16.120 --> 01:08:21.720
there so then he could add the steepness of being a little bit more on that
782
01:08:21.720 --> 01:08:23.320
left side
783
01:08:23.320 --> 01:08:30.600
if he can handle it if not then by shallowing it it would allow him to get a
784
01:08:30.600 --> 01:08:31.240
little bit more
785
01:08:31.240 --> 01:08:37.240
body rotation off that right side so he might still hit him a little bit thin
786
01:08:37.240 --> 01:08:42.760
but I think it would help clean up the potential of some of the left misses
787
01:08:42.760 --> 01:08:50.680
so other than that I mean it looks like you've done a really great job with him
788
01:08:52.200 --> 01:08:56.040
because he's got limitations on the left arm and left leg I would train the
789
01:08:56.040 --> 01:08:57.160
right side
790
01:08:57.160 --> 01:09:07.000
to be as good as possible so if you're I'm not sure how detail focused you've
791
01:09:07.000 --> 01:09:08.120
been but potentially
792
01:09:08.120 --> 01:09:19.160
through there getting a little bit more of kind of that right arm staying ahead
793
01:09:19.160 --> 01:09:19.880
or
794
01:09:19.880 --> 01:09:26.120
a more of that right arm staying external a little bit longer but holy cow I
795
01:09:26.120 --> 01:09:26.840
told you this was one
796
01:09:26.840 --> 01:09:30.720
of the toughest ones when I looked at it because he checks a lot of my just
797
01:09:30.720 --> 01:09:32.360
core fundamental boxes so
798
01:09:32.360 --> 01:09:39.720
I'd say a little bit of low point control and possibly some games to try to
799
01:09:39.720 --> 01:09:43.160
dial in low point
800
01:09:43.160 --> 01:09:51.880
control and trajectory for improving his iron play so I see a question from Ed
801
01:09:51.880 --> 01:09:53.400
at regarding
802
01:09:53.400 --> 01:09:56.900
unhinging I know we have been discussing this move a fair amount but this move
803
01:09:56.900 --> 01:09:57.880
seems to be more
804
01:09:57.880 --> 01:10:04.720
of a flip as the golfer comes into impact yeah shot 39 last week also will this
805
01:10:04.720 --> 01:10:06.200
cause one to lose
806
01:10:06.200 --> 01:10:12.480
club head speed I tend to find the opposite and when you say this golfer did
807
01:10:12.480 --> 01:10:13.800
you mean the first
808
01:10:13.800 --> 01:10:22.060
one I showed or this Craig student here I tend to find that the earlier owner
809
01:10:22.060 --> 01:10:23.880
deviation doesn't
810
01:10:23.880 --> 01:10:28.620
leave club head speed because you mean you're able to increase your wrist
811
01:10:28.620 --> 01:10:29.960
extension so you're
812
01:10:29.960 --> 01:10:37.030
still able to load the wrist quite maximally you're just you're the biggest
813
01:10:37.030 --> 01:10:39.320
thing is that it tends to
814
01:10:39.320 --> 01:10:45.430
feel less flippy down at the bottom so you're able to get more club head speed
815
01:10:45.430 --> 01:10:46.520
from the body
816
01:10:46.520 --> 01:10:54.150
and the trail wrist extension you're you're not getting and you typically don't
817
01:10:54.150 --> 01:10:55.320
stall as much
818
01:10:56.040 --> 01:11:01.530
so you get the speed to build later where a lot of golfers who go into more of
819
01:11:01.530 --> 01:11:02.120
that massive
820
01:11:02.120 --> 01:11:07.800
radial actually lose like they peak their club head speed a little bit too soon
821
01:11:07.800 --> 01:11:09.640
because
822
01:11:09.640 --> 01:11:13.880
but it feels powerful that's the the one thing I'm always up against with
823
01:11:13.880 --> 01:11:15.400
training owner deviation
824
01:11:15.400 --> 01:11:20.880
is the feeling the perceived feeling of power and speed versus the actual
825
01:11:20.880 --> 01:11:22.600
reality of power and speed
826
01:11:22.600 --> 01:11:32.750
so we covered the I think that the owner deviation is one of the the two key
827
01:11:32.750 --> 01:11:33.880
shallowing movements for
828
01:11:33.880 --> 01:11:38.810
the arms and so if you want to have a good wipe you need it if you want to have
829
01:11:38.810 --> 01:11:40.120
less of a stall you
830
01:11:40.120 --> 01:11:45.710
need it I just think it's a really important movement for developing a really
831
01:11:45.710 --> 01:11:46.840
good flat spot
832
01:11:46.840 --> 01:11:58.840
down at the bottom so the and the thing is here let me pull up
833
01:12:01.000 --> 01:12:10.680
since we're answering some chats anyway okay so when you go in towards when you
834
01:12:10.680 --> 01:12:11.880
go in towards
835
01:12:11.880 --> 01:12:16.260
owner deviation it makes it really hard to flip a flip is when you're going
836
01:12:16.260 --> 01:12:18.840
into either increased
837
01:12:18.840 --> 01:12:24.630
extension or increased flexion of the trail wrist so that way this way is
838
01:12:24.630 --> 01:12:27.400
actually one of the key
839
01:12:28.040 --> 01:12:33.960
components going that way is what gets the club in line with the forearm so it
840
01:12:33.960 --> 01:12:35.160
can actually
841
01:12:35.160 --> 01:12:41.790
and it because it's coupled with flexion it'll actually delay the the flipping
842
01:12:41.790 --> 01:12:43.080
of the club so
843
01:12:43.080 --> 01:12:47.880
it tends to help with low point and like I said if you get past the feeling of
844
01:12:47.880 --> 01:12:49.320
it being less powerful
845
01:12:49.320 --> 01:12:53.910
and if you're capable of creating speed from your hips in your core then it
846
01:12:53.910 --> 01:12:55.080
ends up producing
847
01:12:55.080 --> 01:13:00.570
more club head speed but feeling slower it's a weird pattern but i've seen it
848
01:13:00.570 --> 01:13:01.400
consistently enough
849
01:13:01.400 --> 01:13:06.390
that i'm pretty confident with it um is there a optimal pattern for hip
850
01:13:06.390 --> 01:13:07.880
rotation for example
851
01:13:07.880 --> 01:13:14.030
supinating both ankles and straightening the left leg faster um it's a good
852
01:13:14.030 --> 01:13:16.600
question um i've got
853
01:13:18.040 --> 01:13:23.530
because i have guys who have really high club head speeds and really high
854
01:13:23.530 --> 01:13:24.600
performance on
855
01:13:24.600 --> 01:13:33.230
like there were some pretty solid golfers i used in the powerpoint today on
856
01:13:33.230 --> 01:13:35.560
both ends of the spectrum
857
01:13:35.560 --> 01:13:41.160
so one of the golfer who had the dual external rotation is a very good ball
858
01:13:41.160 --> 01:13:42.120
striker world class
859
01:13:42.120 --> 01:13:48.060
and one of the golfers who had the look of less external rotation is you know
860
01:13:48.060 --> 01:13:49.000
top 10
861
01:13:49.000 --> 01:13:55.240
one of the guys that you commonly see as an example of an elite ball striker so
862
01:13:55.240 --> 01:13:56.440
i don't necessarily
863
01:13:56.440 --> 01:14:02.820
think that there is that one is vastly superior to the other um but i do think
864
01:14:02.820 --> 01:14:04.680
that the supination
865
01:14:04.680 --> 01:14:16.360
pattern um possibly requires less nuance in the release um so the the danger
866
01:14:16.360 --> 01:14:17.560
the danger of going
867
01:14:17.560 --> 01:14:21.630
the opposite where you have more of the pronation pattern is i think that you
868
01:14:21.630 --> 01:14:23.560
run into some barriers
869
01:14:23.560 --> 01:14:27.440
in the left leg so you have to have a little bit more of the vertical coming
870
01:14:27.440 --> 01:14:28.600
off the ground and have
871
01:14:28.600 --> 01:14:34.280
it really spin in the air um in order to get through the ball without stalling
872
01:14:34.280 --> 01:14:35.560
uh and i think
873
01:14:35.560 --> 01:14:41.410
that that can create a little bit more timing issues um i don't i don't
874
01:14:41.410 --> 01:14:44.200
necessarily think that
875
01:14:44.200 --> 01:14:53.080
one is vastly superior in terms of the um power output um now for the trail leg
876
01:14:53.080 --> 01:14:54.040
as far as the
877
01:14:54.040 --> 01:14:59.220
amount of timing of the knee straightening i do think there is you know you you
878
01:14:59.220 --> 01:15:00.520
saw that there
879
01:15:00.520 --> 01:15:04.800
are a couple different ways to hit that zone but if you're not loading the
880
01:15:04.800 --> 01:15:06.680
ankle and the the hip
881
01:15:06.680 --> 01:15:11.190
then i think you're leaving a lot out there and that's where a lot a lot more
882
01:15:11.190 --> 01:15:11.960
amateurs in my
883
01:15:11.960 --> 01:15:17.000
opinion suffer from poor trail leg mechanics then lead leg mechanics
884
01:15:17.000 --> 01:15:30.200
okay i had one other golfer to take a look at um let's zoom in
885
01:15:33.800 --> 01:15:42.360
just leave it like this okay so Ian sent in one of his students
886
01:15:42.360 --> 01:15:49.320
and we've got it kind of in frame by frame mode
887
01:15:49.320 --> 01:16:00.990
okay so i'll let you you know think about it gather your thoughts before i jump
888
01:16:00.990 --> 01:16:01.160
in
889
01:16:03.960 --> 01:16:11.800
okay and then we'll move over to the down the line
890
01:16:33.880 --> 01:16:38.360
okay you got some ideas
891
01:16:38.360 --> 01:16:44.840
if you want to comment you can so if i was looking through this golfer um some
892
01:16:44.840 --> 01:16:46.520
of the questions i
893
01:16:46.520 --> 01:16:52.020
would be asking um i think that um the the priorities that i tend to go at um i
894
01:16:52.020 --> 01:16:53.560
talked about in the
895
01:16:53.560 --> 01:16:59.050
the level two a couple weeks ago um i try to go for solid contact then straight
896
01:16:59.050 --> 01:16:59.640
then far
897
01:17:00.520 --> 01:17:05.370
usually in that order i imagine that this golfer tends to have more straight
898
01:17:05.370 --> 01:17:08.200
ness uh than solid
899
01:17:08.200 --> 01:17:13.210
contact if you look at it you know if we go to impact and and just look at some
900
01:17:13.210 --> 01:17:14.760
rough kind of
901
01:17:14.760 --> 01:17:21.160
path ideas it tends to be i'd say straighter than if i brought it back and we
902
01:17:21.160 --> 01:17:22.520
looked at more
903
01:17:23.640 --> 01:17:29.120
the low point considerations which would be where is this sternum and and where
904
01:17:29.120 --> 01:17:29.880
is his arms
905
01:17:29.880 --> 01:17:38.840
so at impact that's fairly vertical and a little bit more more back so now i'm
906
01:17:38.840 --> 01:17:39.320
going to
907
01:17:39.320 --> 01:17:44.360
relate the two together now the good news i would if i was working with this
908
01:17:44.360 --> 01:17:45.640
golfer in person and
909
01:17:45.640 --> 01:17:49.870
say okay you've got great arm extension that's going to be a huge benefit um we
910
01:17:49.870 --> 01:17:51.000
've got a pretty
911
01:17:51.640 --> 01:17:58.680
stable yeah right uh i agree with drive hold right arm straightens too soon
912
01:17:58.680 --> 01:18:00.200
lack of white movement
913
01:18:00.200 --> 01:18:05.040
so we'll we'll circle back to that um so there's where we can see that the
914
01:18:05.040 --> 01:18:06.680
right arm is straightening
915
01:18:06.680 --> 01:18:11.620
too soon so as a result the shaft is pretty vertical at impact but he does a
916
01:18:11.620 --> 01:18:13.080
pretty good job of
917
01:18:13.080 --> 01:18:17.760
getting into some good arm extension on the way through i just don't love the
918
01:18:17.760 --> 01:18:19.080
way he gets there
919
01:18:19.080 --> 01:18:24.130
so i would imagine that solid contact is one of our bigger issues i'm actually
920
01:18:24.130 --> 01:18:24.600
gonna
921
01:18:24.600 --> 01:18:28.680
pull him up in both spots we'll see if we can do it this way
922
01:18:28.680 --> 01:18:39.880
all right way to trick it okay so now
923
01:18:44.200 --> 01:18:50.440
so now if we look at when so right around here is where something that looks
924
01:18:50.440 --> 01:18:51.480
off right there's a
925
01:18:51.480 --> 01:18:56.970
lot of space there um the arms are way behind his body if i bring it down to
926
01:18:56.970 --> 01:18:58.360
about the same position
927
01:18:58.360 --> 01:19:03.320
from the down the line you'd say oh this looks like it's way inside but the
928
01:19:03.320 --> 01:19:04.680
reason that it looks
929
01:19:04.680 --> 01:19:11.310
way inside is because there's not a lot of body rotation at this point right
930
01:19:11.310 --> 01:19:13.640
you can see his hips
931
01:19:13.640 --> 01:19:20.360
and his chest are at the most pointing at the golf ball but probably close to
932
01:19:20.360 --> 01:19:21.240
the target
933
01:19:21.240 --> 01:19:26.460
so if i was to grab the club and freeze him there and then have him turn his
934
01:19:26.460 --> 01:19:28.200
body more towards the
935
01:19:28.200 --> 01:19:34.450
target what would happen is that elbow would work its way more in front in
936
01:19:34.450 --> 01:19:37.400
order to um allow for the
937
01:19:37.400 --> 01:19:43.240
left arm to stay in contact so i think that this is more of a sequencing issue
938
01:19:43.240 --> 01:19:43.480
can
939
01:19:43.480 --> 01:19:51.480
creating a low point issue now we usually when you start getting the body more
940
01:19:51.480 --> 01:19:52.280
open
941
01:19:52.280 --> 01:19:57.170
there's a chance that the the face will get left open when he gets more shaft
942
01:19:57.170 --> 01:19:57.880
lean so that'd be
943
01:19:57.880 --> 01:20:03.700
something that i would at least experiment with or keep an eye on but the main
944
01:20:03.700 --> 01:20:05.000
issue i see for him
945
01:20:05.000 --> 01:20:09.330
would be getting a little bit improved sequencing um which would help keep the
946
01:20:09.330 --> 01:20:10.600
arms more in front
947
01:20:10.600 --> 01:20:18.280
so a pump drill or um you know some rope training or uh you know if you know
948
01:20:18.280 --> 01:20:19.160
some of the hands-on
949
01:20:19.160 --> 01:20:24.650
stuff where you're going in um i would do the one where i like to hold on to
950
01:20:24.650 --> 01:20:27.480
the club and get the
951
01:20:27.480 --> 01:20:30.650
body to feel more open or if you were doing it by yourself you would use
952
01:20:30.650 --> 01:20:32.040
something like the wall
953
01:20:32.040 --> 01:20:37.880
drill um or the reverse pump like all those would kind of help get a sense of
954
01:20:37.880 --> 01:20:39.800
the arms more in front
955
01:20:39.800 --> 01:20:45.900
now the thing that he will have to adjust for is if we look at the height there
956
01:20:45.900 --> 01:20:47.800
you'll notice
957
01:20:47.800 --> 01:20:56.200
that if we were to delay that right arm he would probably top the ball unless
958
01:20:56.200 --> 01:20:58.920
he in addition to
959
01:20:58.920 --> 01:21:04.870
getting more body rotation also um got a little bit more bent over um to
960
01:21:04.870 --> 01:21:07.240
account for the distance
961
01:21:07.240 --> 01:21:11.320
difference in the right arm straightening so i would experiment with some
962
01:21:11.320 --> 01:21:12.440
transition pump type
963
01:21:12.440 --> 01:21:17.480
stuff and then i would probably circle back to some impact or release drills
964
01:21:17.480 --> 01:21:18.840
feeling closer to
965
01:21:18.840 --> 01:21:24.130
the ground um i i tell golfers all the time that there's two ways to avoid
966
