Pelvis Angles

WEBVTT

1
00:00:00.000 --> 00:00:04.320
All right, coaches, in this presentation, we're going to take a look at the pel

2
00:00:04.320 --> 00:00:05.320
vis angle's

3
00:00:05.320 --> 00:00:06.320
graph.

4
00:00:06.320 --> 00:00:11.520
So the angles graphs, the pelvis angle graph is looking at the three linear or

5
00:00:11.520 --> 00:00:12.120
angular

6
00:00:12.120 --> 00:00:13.120
motions.

7
00:00:13.120 --> 00:00:18.240
So if we imagine kind of tilting forward backward, side to side or rotation,

8
00:00:18.240 --> 00:00:20.340
those are the three

9
00:00:20.340 --> 00:00:23.280
angular movements the body can make.

10
00:00:23.280 --> 00:00:27.250
So as always, we're going to look at examples of torporos and amateurs, we're

11
00:00:27.250 --> 00:00:27.880
going to talk

12
00:00:27.880 --> 00:00:35.220
about the anatomy and overall movement concepts related to the pelvis rotations

13
00:00:35.220 --> 00:00:35.640
.

14
00:00:35.640 --> 00:00:41.340
When we're looking at the pelvis rotations, there's three different graphs that

15
00:00:41.340 --> 00:00:41.840
we'll

16
00:00:41.840 --> 00:00:42.840
look at.

17
00:00:42.840 --> 00:00:47.040
One is open closed, which is basically rotating towards or away from the target

18
00:00:47.040 --> 00:00:47.240
.

19
00:00:47.240 --> 00:00:49.920
You have pelvis bend forward backward.

20
00:00:49.920 --> 00:00:58.200
So this one will closely mimic anterior pelvis tilt, posterior pelvis tilt.

21
00:00:58.200 --> 00:01:04.160
So if you were looking at my pelvis this way, tilting forward and backward

22
00:01:04.160 --> 00:01:05.040
would be in

23
00:01:05.040 --> 00:01:07.480
this plane here.

24
00:01:07.480 --> 00:01:13.180
But I could also do it by kind of shifting more like this, where I'm not truly

25
00:01:13.180 --> 00:01:13.640
going

26
00:01:13.640 --> 00:01:20.200
into anterior posterior tilt, but the pelvis graph would show a change in the

27
00:01:20.200 --> 00:01:21.080
angle because

28
00:01:21.080 --> 00:01:23.720
I am changing that angle.

29
00:01:23.720 --> 00:01:26.680
And then last would be side to side tilt.

30
00:01:26.680 --> 00:01:31.320
So pelvis going this way or if I was doing like a little hip hike.

31
00:01:31.320 --> 00:01:35.220
Now you want to think about how each system is measuring or where it's

32
00:01:35.220 --> 00:01:35.920
measuring from.

33
00:01:35.920 --> 00:01:37.200
It is less important.

34
00:01:37.200 --> 00:01:42.090
It's a lot less critical for the angular graphs than it is for the linear

35
00:01:42.090 --> 00:01:42.960
graphs.

36
00:01:42.960 --> 00:01:47.830
So we'll talk about that a little bit more in the linear graphs for the pelvis

37
00:01:47.830 --> 00:01:48.440
and the

38
00:01:48.440 --> 00:01:49.440
thorax.

39
00:01:49.440 --> 00:01:54.640
Okay, so as always, we're just going to pop up a couple graphs to look at.

40
00:01:54.640 --> 00:01:56.160
This is grant weight.

41
00:01:56.160 --> 00:02:00.040
We've got address, this black line here, it's a timeline.

42
00:02:00.040 --> 00:02:04.320
So we got address top of the swing, impact, finish.

43
00:02:04.320 --> 00:02:06.960
So all this space here is the backswing.

44
00:02:06.960 --> 00:02:11.000
All this space here is the downswing and then this is the follow through.

45
00:02:11.000 --> 00:02:15.270
The red line is the pelvis rotation, the green line is the pelvis forward and

46
00:02:15.270 --> 00:02:16.760
backward bend

47
00:02:16.760 --> 00:02:19.720
and then the blue line is the pelvis side bend.

48
00:02:19.720 --> 00:02:26.350
If we look, we're going to see somewhat similar pattern here for Henrik Stenson

49
00:02:26.350 --> 00:02:26.720
.

50
00:02:26.720 --> 00:02:28.920
Somewhat similar pattern here for Steve Elkington.

51
00:02:28.920 --> 00:02:35.260
Now it's important to note that when we look at these graphs kind of in total,

52
00:02:35.260 --> 00:02:36.040
you'll see

53
00:02:36.040 --> 00:02:38.400
a very similar pattern.

54
00:02:38.400 --> 00:02:42.980
But part of that is the rotation graph because the scale is so big, kind of was

55
00:02:42.980 --> 00:02:43.760
hes out some

56
00:02:43.760 --> 00:02:47.360
of the details of the other two graphs.

57
00:02:47.360 --> 00:02:54.330
But that said, you typically won't see, let's say, huge variations in the

58
00:02:54.330 --> 00:02:56.160
angular graphs.

59
00:02:56.160 --> 00:03:00.360
Okay, so 3D guidelines, as always, I'll just quickly go through this at the

60
00:03:00.360 --> 00:03:01.400
beginning of

61
00:03:01.400 --> 00:03:05.480
each presentation, just to remind you, 3D graphs don't give the answers, rather

62
00:03:05.480 --> 00:03:06.080
they tell

63
00:03:06.080 --> 00:03:09.980
you where to focus your attention when analyzing the movement, whether it's

64
00:03:09.980 --> 00:03:10.840
with your palpation

65
00:03:10.840 --> 00:03:17.550
skills, whether it's with video, whether it's with trying different drills that

66
00:03:17.550 --> 00:03:18.520
would correct

67
00:03:18.520 --> 00:03:25.650
a certain issue, the graphs will help you focus on an area and a time within a

68
00:03:25.650 --> 00:03:26.680
swing.

69
00:03:26.680 --> 00:03:33.400
Never look at only one graph that can definitely skew what your, kind of your

70
00:03:33.400 --> 00:03:36.040
overall take.

71
00:03:36.040 --> 00:03:38.740
So it's important to look at those system as a whole, how are they controlling

72
00:03:38.740 --> 00:03:39.560
low point,

73
00:03:39.560 --> 00:03:43.460
how are they creating speed, how are they controlling the face, and then work

74
00:03:43.460 --> 00:03:43.880
the graphs

75
00:03:43.880 --> 00:03:48.360
into your understanding of how the golfer is swinging the club and controlling

76
00:03:48.360 --> 00:03:48.760
each

77
00:03:48.760 --> 00:03:52.320
of those key variables.

78
00:03:52.320 --> 00:03:54.240
Similar to that is think in movement.

79
00:03:54.240 --> 00:03:58.500
Remember the movement rules from the position classes, looking at what's moving

80
00:03:58.500 --> 00:04:00.520
, fixed point,

81
00:04:00.520 --> 00:04:06.040
making relationships, so how one part of the body affects another.

82
00:04:06.040 --> 00:04:09.940
That's probably the biggest, most important one for looking at these graphs

83
00:04:09.940 --> 00:04:10.160
because you're

84
00:04:10.160 --> 00:04:14.360
going to get one specific area and if you just focus in on that one area

85
00:04:14.360 --> 00:04:15.920
without understanding

86
00:04:15.920 --> 00:04:21.620
how it relates to the whole, it's easy to get, it's easy to misdiagnose the

87
00:04:21.620 --> 00:04:22.480
issue.

88
00:04:22.480 --> 00:04:26.380
The other big one here is think about what phase, so with these timelines it's

89
00:04:26.380 --> 00:04:26.640
really

90
00:04:26.640 --> 00:04:31.360
easy to get a snapshot of the whole movement at that particular segment.

91
00:04:31.360 --> 00:04:37.320
But you want to, whatever phase you're focusing on, pay attention to what the

92
00:04:37.320 --> 00:04:38.040
major goals

93
00:04:38.040 --> 00:04:42.880
are there from both a power, face, and path perspective.

94
00:04:42.880 --> 00:04:48.840
The other ones are a little bit more, kind of video based, but they all relate

95
00:04:48.840 --> 00:04:49.920
to analyzing

96
00:04:49.920 --> 00:04:50.920
the movement.

97
00:04:50.920 --> 00:04:54.760
So keep them in the back of your mind as you're looking through these graphs.

98
00:04:54.760 --> 00:04:59.800
We did anatomy to the pelvis graph, so it's important to recognize that the pel

99
00:04:59.800 --> 00:05:00.500
vis graph

100
00:05:00.500 --> 00:05:04.920
is registering what's happening at this block, what's happening at the pelvis.

101
00:05:04.920 --> 00:05:10.080
So everything below it and a little bit above it is influencing this pelvis.

102
00:05:10.080 --> 00:05:14.730
Specifically the major area we're looking at is the pelvis, which is the

103
00:05:14.730 --> 00:05:15.720
intersection

104
00:05:15.720 --> 00:05:21.050
of the spine and it goes through the sacrum and the pelvis connects to the

105
00:05:21.050 --> 00:05:22.360
spine through

106
00:05:22.360 --> 00:05:27.920
the sacroiliac joint or the SIJ.

107
00:05:27.920 --> 00:05:33.950
The key muscles in that area are your core, so your abs, your low back, your QL

108
00:05:33.950 --> 00:05:34.680
and your

109
00:05:34.680 --> 00:05:38.360
lats are two of the big back muscles related to golf.

110
00:05:38.360 --> 00:05:43.400
You've also got your kind of deep spine and your deep abs, but these are some

111
00:05:43.400 --> 00:05:44.080
of the big

112
00:05:44.080 --> 00:05:45.520
movers that we're looking at.

113
00:05:45.520 --> 00:05:50.030
When you're looking at the lower limb, the hips have a big influence on what

114
00:05:50.030 --> 00:05:50.640
happens

115
00:05:50.640 --> 00:05:56.670
at the pelvis, because they are the big movers of the ilium, but you can also

116
00:05:56.670 --> 00:05:57.440
look at what's

117
00:05:57.440 --> 00:05:59.440
happening at the feet and the knees.

118
00:05:59.440 --> 00:06:04.780
With the hips, you've got your glutes as one of the big areas to focus on as

119
00:06:04.780 --> 00:06:05.560
well as

120
00:06:05.560 --> 00:06:07.720
the quads, opposite the quads.

121
00:06:07.720 --> 00:06:14.030
You've got your hamstrings and your deep rotators on the, and then you've got

122
00:06:14.030 --> 00:06:15.240
kind of the inside

123
00:06:15.240 --> 00:06:20.480
and the outside of the legs, so your adductors and avi-ductors.

124
00:06:20.480 --> 00:06:23.440
Just a quick refresher on the hip joint.

125
00:06:23.440 --> 00:06:29.240
This is from last year's or level one anatomy sections.

126
00:06:29.240 --> 00:06:32.800
We've got a flexion of the hip, extension of the hip.

127
00:06:32.800 --> 00:06:36.710
You've got abduction as well as adduction, so going out to the side and then

128
00:06:36.710 --> 00:06:37.400
you've got

129
00:06:37.400 --> 00:06:42.040
internal and external rotation.

130
00:06:42.040 --> 00:06:51.300
With the pelvis, the pelvis has, it can move in this oblique axis way along the

131
00:06:51.300 --> 00:06:52.840
SI joint,

132
00:06:52.840 --> 00:06:57.570
but at the hip, typical pelvis movement is going to be looked at anterior and

133
00:06:57.570 --> 00:06:58.320
posterior

134
00:06:58.320 --> 00:06:59.320
tilt.

135
00:06:59.320 --> 00:07:04.470
Again, you've got anterior tilt when the pelvis tips forward, posterior tilt

136
00:07:04.470 --> 00:07:05.680
when the pelvis

137
00:07:05.680 --> 00:07:10.760
tips backward like so.

138
00:07:10.760 --> 00:07:18.000
The classic patterns are if the pelvis tips forward, so this can either go from

139
00:07:18.000 --> 00:07:18.560
the top

140
00:07:18.560 --> 00:07:19.920
down or from the bottom up.

141
00:07:19.920 --> 00:07:25.880
If the pelvis tips forward, that lowers that side, so the hip rotates

142
00:07:25.880 --> 00:07:27.000
internally because

143
00:07:27.000 --> 00:07:30.220
of the shape of the hip and when it rotates forward like this, it actually rot

144
00:07:30.220 --> 00:07:30.720
ates like

145
00:07:30.720 --> 00:07:34.800
that, which pulls the hip around and rotates it internally.

146
00:07:34.800 --> 00:07:40.760
The lower leg follows and rotates internally and then the foot falls inward or

147
00:07:40.760 --> 00:07:41.720
pronates.

148
00:07:41.720 --> 00:07:42.720
That could happen at the foot.

149
00:07:42.720 --> 00:07:48.400
If the foot pronates, the tibia rotates internally, the hip rotates internally,

150
00:07:48.400 --> 00:07:50.240
so then the pelvis

151
00:07:50.240 --> 00:07:51.840
tilts anteriorly.

152
00:07:51.840 --> 00:07:53.920
This is one of the common dysfunctions.

153
00:07:53.920 --> 00:07:57.990
The opposite would be if you get too much of a supination of the foot, tibia

154
00:07:57.990 --> 00:07:58.520
rotates

155
00:07:58.520 --> 00:08:04.640
outward, knee rotates outward, pelvis tilts posteriorly.

156
00:08:04.640 --> 00:08:06.240
The opposite.

157
00:08:06.240 --> 00:08:12.780
Just as a little reminder, this is the natural movement of the pelvis and the

158
00:08:12.780 --> 00:08:13.880
SI joint.

159
00:08:13.880 --> 00:08:23.290
They move in this walking fashion like this, and that's part of what creates

160
00:08:23.290 --> 00:08:25.000
rotation.

161
00:08:25.000 --> 00:08:29.400
You can see that this can get stuck either at what's happening at the hip.

162
00:08:29.400 --> 00:08:31.920
This can get stuck at what's happening at the lower back.

163
00:08:31.920 --> 00:08:36.140
This could get stuck at what's happening at the glutes or the abs.

164
00:08:36.140 --> 00:08:42.120
There's lots of places where this "simple" movement could get stuck.

165
00:08:42.120 --> 00:08:47.090
When it comes to looking at the muscles, it's better to look at it in their

166
00:08:47.090 --> 00:08:48.360
chains or the

167
00:08:48.360 --> 00:08:49.360
facial links.

168
00:08:49.360 --> 00:08:52.400
We're going to bring up the pictures from anatomy trains.

169
00:08:52.400 --> 00:08:56.820
These are the big ones for looking at what could be going on in the core as

170
00:08:56.820 --> 00:08:57.440
well as the

171
00:08:57.440 --> 00:08:58.440
pelvis.

172
00:08:58.440 --> 00:09:02.340
The spiral line here on the left and the functional lines here on the right,

173
00:09:02.340 --> 00:09:03.760
spiral line goes

174
00:09:03.760 --> 00:09:07.770
from the rhomboids to the serratus to the external oblique to the internal ob

175
00:09:07.770 --> 00:09:08.400
lique and

176
00:09:08.400 --> 00:09:12.600
then down the lower leg to the foot and then back up through the hamstring into

177
00:09:12.600 --> 00:09:13.160
the lower

178
00:09:13.160 --> 00:09:15.640
back like so.

179
00:09:15.640 --> 00:09:18.960
It creates this kind of "x" around the body.

180
00:09:18.960 --> 00:09:24.200
Those "x"s are great at rotating the trunk on top of the pelvis.

181
00:09:24.200 --> 00:09:30.480
The diagonal lines, you've got the rotational line of the lat to the glute.

182
00:09:30.480 --> 00:09:34.390
When the fibers are going, in order to rotate, you need the fibers going more

183
00:09:34.390 --> 00:09:35.440
diagonally.

184
00:09:35.440 --> 00:09:39.850
When you look at the obliques and serratus, you can see that those go diagon

185
00:09:39.850 --> 00:09:40.640
ally across

186
00:09:40.640 --> 00:09:43.360
the body, those create rotation.

187
00:09:43.360 --> 00:09:50.230
When we look at this functional line here, the peck can rotate the arm, but it

188
00:09:50.230 --> 00:09:51.000
doesn't

189
00:09:51.000 --> 00:09:55.640
go far enough down to rotate the spine in the trunk.

190
00:09:55.640 --> 00:09:59.120
The rectus, the six-pack abs, it's more straight up and down and it doesn't

191
00:09:59.120 --> 00:10:01.600
create any rotation.

192
00:10:01.600 --> 00:10:03.160
Doctors very little.

193
00:10:03.160 --> 00:10:11.720
We need to engage the lats or the obliques, the transverso spinalis.

194
00:10:11.720 --> 00:10:15.920
Those are the big muscles that will rotate the trunk, one of the key movements

195
00:10:15.920 --> 00:10:16.240
of the

196
00:10:16.240 --> 00:10:17.920
golf swing.

197
00:10:17.920 --> 00:10:23.880
We get these kind of look of shoulder and hip working in tandem because of

198
00:10:23.880 --> 00:10:25.280
either the obliques

199
00:10:25.280 --> 00:10:29.280
on the front side or the lats on the back side.

200
00:10:29.280 --> 00:10:35.240
Now it's important to recognize that the quad muscles, which we'll look at in

201
00:10:35.240 --> 00:10:36.000
this next

202
00:10:36.000 --> 00:10:39.040
slide, all run vertically.

203
00:10:39.040 --> 00:10:43.050
They don't create a whole lot of rotation very easily, especially they don't

204
00:10:43.050 --> 00:10:43.480
link to

205
00:10:43.480 --> 00:10:48.840
rotation in the core, same way your adductors and your glutes would.

206
00:10:48.840 --> 00:10:55.440
Here's a little better picture of these crossing fibers that work across.

207
00:10:55.440 --> 00:10:59.920
You could see that if they tighten, they're going to create some torsion and

208
00:10:59.920 --> 00:11:01.000
some rotation.

209
00:11:01.000 --> 00:11:06.960
Same thing with the lat on the one side, creating a shortening and a downward

210
00:11:06.960 --> 00:11:07.600
movement going

211
00:11:07.600 --> 00:11:09.240
this way.

212
00:11:09.240 --> 00:11:13.140
If you combo that with the oblique on the opposite side, you can create some

213
00:11:13.140 --> 00:11:15.680
powerful rotation.

214
00:11:15.680 --> 00:11:21.840
Here's a picture looking more at the quads tend to run vertically.

215
00:11:21.840 --> 00:11:27.330
When you get your quad activity happening, that's tending to load more pulling

216
00:11:27.330 --> 00:11:28.120
the trunk

217
00:11:28.120 --> 00:11:33.580
down or rotating the shoulder girdle, but it doesn't do a really good job of

218
00:11:33.580 --> 00:11:34.200
linking

219
00:11:34.200 --> 00:11:39.200
to rotating the spine.

220
00:11:39.200 --> 00:11:41.440
Now what are the pelvis goals in the golf swing?

221
00:11:41.440 --> 00:11:43.970
When we look at these graphs, we want to have a little bit of a framework as

222
00:11:43.970 --> 00:11:44.440
far as what

223
00:11:44.440 --> 00:11:46.240
we're expecting to see.

224
00:11:46.240 --> 00:11:51.530
First, you've got rotation of the hips to load the glute muscles and create

225
00:11:51.530 --> 00:11:52.280
depth.

226
00:11:52.280 --> 00:11:55.680
The glute muscles are one of the most active and powerful muscles in the golf

227
00:11:55.680 --> 00:11:56.680
swing, especially

228
00:11:56.680 --> 00:12:00.590
the right glute or trail glute for right hand golfer, but in order to use it,

229
00:12:00.590 --> 00:12:01.120
you've got

230
00:12:01.120 --> 00:12:05.480
to rotate into that hip socket in the backswing.

231
00:12:05.480 --> 00:12:11.940
The pelvis transfers the energy from the legs to the floor so when you push in

232
00:12:11.940 --> 00:12:13.040
transition

233
00:12:13.040 --> 00:12:17.240
using your core and pushing against the ground, that allows you to then create

234
00:12:17.240 --> 00:12:17.960
that ground

235
00:12:17.960 --> 00:12:23.080
reaction force and that reaction force comes back up.

236
00:12:23.080 --> 00:12:27.750
The pelvis transfers that reaction force from the floor all the way up to the

237
00:12:27.750 --> 00:12:28.680
ribs and shoulders

238
00:12:28.680 --> 00:12:31.160
and ultimately into the arms.

239
00:12:31.160 --> 00:12:35.800
The pelvis also helps maintain posture so we're playing on this tilted angle

240
00:12:35.800 --> 00:12:37.240
down at the golf

241
00:12:37.240 --> 00:12:42.190
ball sitting on the ground so you could either bend from the spine or you could

242
00:12:42.190 --> 00:12:42.920
bend from

243
00:12:42.920 --> 00:12:48.320
the hips and the pelvis does a good job of maintaining that angle towards the

244
00:12:48.320 --> 00:12:49.160
ground.

245
00:12:49.160 --> 00:12:55.180
It also creates the axis tilt which allows us to create a nice flat spot.

246
00:12:55.180 --> 00:13:00.300
It helps position the upper body for precision of low point control as well as

247
00:13:00.300 --> 00:13:01.180
that flat spot

248
00:13:01.180 --> 00:13:07.740
so that's that blend of side tilt as well as forward bend, keeping that upper

249
00:13:07.740 --> 00:13:08.380
body in

250
00:13:08.380 --> 00:13:13.160
a precise location so that when you use your arms, you can control to a very

251
00:13:13.160 --> 00:13:14.060
high degree

252
00:13:14.060 --> 00:13:16.260
how the club is hitting you around.

253
00:13:16.260 --> 00:13:21.590
Pelvis is also helpful for pressure and mass displacement so shifting your

254
00:13:21.590 --> 00:13:22.580
pressure or

255
00:13:22.580 --> 00:13:28.540
keeping your mass more centered and getting that pressure shift away from the

256
00:13:28.540 --> 00:13:29.200
mass helps

257
00:13:29.200 --> 00:13:31.860
create an ease of power.

258
00:13:31.860 --> 00:13:37.830
We'll talk about that later in the kind of looking at the basic forces

259
00:13:37.830 --> 00:13:39.620
presentation.

260
00:13:39.620 --> 00:13:42.300
Okay, so 3D graphs.

261
00:13:42.300 --> 00:13:45.340
Let's take a look at the pelvis bend.

262
00:13:45.340 --> 00:13:49.170
We're going to break out these three graphs and we're going to look at pelvis

263
00:13:49.170 --> 00:13:49.940
bend first.

264
00:13:49.940 --> 00:13:56.060
With the just kind of stock toward trend, this is pretty much a classic graph

265
00:13:56.060 --> 00:13:56.820
here.

266
00:13:56.820 --> 00:14:01.780
You've got an average of about 20 degrees of bend at the address position.

267
00:14:01.780 --> 00:14:06.780
We lose a little bit here at the top of the swing and then there's a little bit

268
00:14:06.780 --> 00:14:07.380
of this

269
00:14:07.380 --> 00:14:12.870
hip trigger when you stretch your abs or load your hip flexors however you want

270
00:14:12.870 --> 00:14:13.340
to look

271
00:14:13.340 --> 00:14:17.920
at it or sorry when you stretch your abs or use your hip flexors and then we're

272
00:14:17.920 --> 00:14:18.420
going

273
00:14:18.420 --> 00:14:24.060
to have a pretty strong posterior tilt going to impact about so you lose about

274
00:14:24.060 --> 00:14:26.260
10-15 degrees

275
00:14:26.260 --> 00:14:27.860
in the downswing.

276
00:14:27.860 --> 00:14:30.580
Slightly flexing in the backswing.

277
00:14:30.580 --> 00:14:34.260
So if I just look at the pelvis, there's a slight flex in the backswing, there

278
00:14:34.260 --> 00:14:35.140
's a slight

279
00:14:35.140 --> 00:14:39.620
increase in transition and then there's a flexion for most of the downswing.

280
00:14:39.620 --> 00:14:45.110
It doesn't look that way when you're rotating through those phases but that's

281
00:14:45.110 --> 00:14:46.220
what the pelvis

282
00:14:46.220 --> 00:14:50.500
is doing from this perspective.

283
00:14:50.500 --> 00:14:56.900
The key structures, again you got your SI joint, your abs or your abs versus gl

284
00:14:56.900 --> 00:14:57.380
utes

285
00:14:57.380 --> 00:15:01.960
or back and hip flexors, those have a really big influence so part of what

286
00:15:01.960 --> 00:15:02.980
pulls this down

287
00:15:02.980 --> 00:15:07.370
is using the abs, what pulls this up is using the hip flexors, what pulls this

288
00:15:07.370 --> 00:15:08.260
down is using

289
00:15:08.260 --> 00:15:10.420
the abs and glutes.

290
00:15:10.420 --> 00:15:14.770
You can also see some T-spine compensation so if the thoracic spine starts

291
00:15:14.770 --> 00:15:15.980
moving especially

292
00:15:15.980 --> 00:15:22.990
into extension or losing its posture, that can create an excessive kind of dip

293
00:15:22.990 --> 00:15:23.820
here.

294
00:15:23.820 --> 00:15:30.900
And the lumbar spine of course can have a big impact on this sensor as well.

295
00:15:30.900 --> 00:15:36.870
From a swing relationship perspective, you've got, depending on what we see on

296
00:15:36.870 --> 00:15:37.940
this graph,

297
00:15:37.940 --> 00:15:41.250
you want to relate it to the steeps and shallows, especially how much of a

298
00:15:41.250 --> 00:15:42.500
chopped pattern versus

299
00:15:42.500 --> 00:15:51.490
a rotation pattern and understanding that some of the, some of this posterior

300
00:15:51.490 --> 00:15:52.380
tilt could

301
00:15:52.380 --> 00:15:59.290
be early extension which is a closing movement or it could be just a posterior

302
00:15:59.290 --> 00:16:00.380
tilt which

303
00:16:00.380 --> 00:16:03.650
would be an abs movement so you have to be careful and look at some of the

304
00:16:03.650 --> 00:16:04.380
other graphs

305
00:16:04.380 --> 00:16:10.340
to see what this downward sloping graph means if it's a good sign they're using

306
00:16:10.340 --> 00:16:11.180
their abs

307
00:16:11.180 --> 00:16:14.660
or a bad sign that they're really early sending.

308
00:16:14.660 --> 00:16:20.620
TPI has a couple errors when they look at pelvis bend so S posture would be

309
00:16:20.620 --> 00:16:21.220
starting

310
00:16:21.220 --> 00:16:28.340
in a high position so S posture is looking kind of more like this at setup so

311
00:16:28.340 --> 00:16:29.260
we would

312
00:16:29.260 --> 00:16:34.660
see that numbers start well above 20, closer to 30 or an excessive trigger so

313
00:16:34.660 --> 00:16:35.180
as you go

314
00:16:35.180 --> 00:16:42.680
up to the top of the swing as you start down really cranking this way you know

315
00:16:42.680 --> 00:16:43.780
more than

316
00:16:43.780 --> 00:16:50.080
5 degrees or so that can be associated with back pain which TPI is big into

317
00:16:50.080 --> 00:16:51.180
preventing

318
00:16:51.180 --> 00:16:52.980
back pain.

319
00:16:52.980 --> 00:16:59.280
Okay so here's the classic graphs so when the graph goes higher it's tilting

320
00:16:59.280 --> 00:17:00.060
forward

321
00:17:00.060 --> 00:17:03.500
when the graph goes lower it's tilting backward.

322
00:17:03.500 --> 00:17:07.780
So we start here his grant weights graph if you want to pull up his swing you

323
00:17:07.780 --> 00:17:08.300
can watch

324
00:17:08.300 --> 00:17:16.070
along so we've got going into a slightly interior more tilt there in the

325
00:17:16.070 --> 00:17:17.620
takeaway probably

326
00:17:17.620 --> 00:17:23.030
as he's shifting his pressure into the right leg then as he kind of finishes

327
00:17:23.030 --> 00:17:23.900
the back swing

328
00:17:23.900 --> 00:17:31.600
he maintains that crunch position so he maintains the distance or even uses his

329
00:17:31.600 --> 00:17:32.380
abs to shorten

330
00:17:32.380 --> 00:17:37.560
it a little bit then he's going to increase so he's going to go into a little

331
00:17:37.560 --> 00:17:38.240
bit more

332
00:17:38.240 --> 00:17:44.800
of this arch and then he's going to posterior tilt the majority of the down

333
00:17:44.800 --> 00:17:45.660
swing.

334
00:17:45.660 --> 00:17:52.780
Again this is Hendrix Stenson so I kept this in here just because one of the

335
00:17:52.780 --> 00:17:53.700
things that

336
00:17:53.700 --> 00:17:59.660
you want to be careful with when looking at these graphs is the digitization

337
00:17:59.660 --> 00:18:00.340
process

338
00:18:00.340 --> 00:18:08.820
is a little bit of an heart so when in AMM when you're digitizing the pelvis

339
00:18:08.820 --> 00:18:09.900
you have

340
00:18:09.900 --> 00:18:15.470
the sensor back here doesn't really matter where it is because we're digitizing

341
00:18:15.470 --> 00:18:16.140
and then

342
00:18:16.140 --> 00:18:20.570
you help them find where the hips are by the greater trochanters and then you

343
00:18:20.570 --> 00:18:21.500
pick a point

344
00:18:21.500 --> 00:18:25.740
above that greater trochanter and depending on where you pick that point that's

345
00:18:25.740 --> 00:18:26.140
going

346
00:18:26.140 --> 00:18:33.500
to bias the starting position so it looks like this one the the point was

347
00:18:33.500 --> 00:18:34.500
picked kind

348
00:18:34.500 --> 00:18:38.860
of more backward than the neutral pelvis so when he got into his golf posture

349
00:18:38.860 --> 00:18:39.300
it shows

350
00:18:39.300 --> 00:18:43.970
that he's got a really flat or posterior tilt but then it also shows that he

351
00:18:43.970 --> 00:18:45.540
gets into

352
00:18:45.540 --> 00:18:51.500
an incredible amount of negative tilt in the finished position so my guess is

353
00:18:51.500 --> 00:18:51.940
just that

354
00:18:51.940 --> 00:18:57.900
one was mis digitized by probably 10 degrees or so because the overall pattern

355
00:18:57.900 --> 00:18:58.380
is too bad

356
00:18:58.380 --> 00:19:04.730
he does have what appears to be a little bit of an excessive hip trigger that

357
00:19:04.730 --> 00:19:04.820
could

358
00:19:04.820 --> 00:19:11.790
be related to some of his forward lunge and driver issues but overall it's got

359
00:19:11.790 --> 00:19:12.380
kind of

360
00:19:12.380 --> 00:19:17.580
the normal looking pattern to it.

361
00:19:17.580 --> 00:19:21.590
Steve Elkington who did have back pain he's got kind of this excessive hip

362
00:19:21.590 --> 00:19:22.380
trigger a

363
00:19:22.380 --> 00:19:28.080
little bit of possible reverse spine we'll take a look at that when we look at

364
00:19:28.080 --> 00:19:28.820
some of

365
00:19:28.820 --> 00:19:37.500
the upper body when we look at the upper body graphs but starts good position

366
00:19:37.500 --> 00:19:38.620
loses some

367
00:19:38.620 --> 00:19:43.790
up to the top of the swing big excessive arch there in transition and then

368
00:19:43.790 --> 00:19:44.540
loses it the

369
00:19:44.540 --> 00:19:48.300
majority is downswing.

370
00:19:48.300 --> 00:19:53.430
Okay the bend graph problems tpi remember they look at excessive trigger which

371
00:19:53.430 --> 00:19:54.180
we saw even

372
00:19:54.180 --> 00:19:58.860
with the tour pro and s posture which we didn't see any real examples.

373
00:19:58.860 --> 00:20:02.820
I look for in when I'm looking at this I'm looking at excessive pull down in

374
00:20:02.820 --> 00:20:03.540
transition

375
00:20:03.540 --> 00:20:08.760
or excessive pull in during the release so golfers who tend to have an

376
00:20:08.760 --> 00:20:10.060
excessive pull

377
00:20:10.060 --> 00:20:14.580
down in transition could go into more of a excessive tilt so that could be one

378
00:20:14.580 --> 00:20:15.100
reason

379
00:20:15.100 --> 00:20:21.060
for the excessive trigger and then down at the bottom here having more of kind

380
00:20:21.060 --> 00:20:21.140
of a

381
00:20:21.140 --> 00:20:25.520
pull up that could be a reason for going into extension or going into that

382
00:20:25.520 --> 00:20:26.820
posterior tilt

383
00:20:26.820 --> 00:20:35.310
if I'm shorging more like this as opposed to this and that would look very

384
00:20:35.310 --> 00:20:36.580
similar just

385
00:20:36.580 --> 00:20:40.780
pelvis wise so you want to look at all the graphs at the same time and maybe

386
00:20:40.780 --> 00:20:41.420
even look

387
00:20:41.420 --> 00:20:48.820
at videos so that you can see which version of movement this graph is depicting

388
00:20:48.820 --> 00:20:49.380
okay when

389
00:20:49.380 --> 00:20:55.370
we look at some amateurs here we're going to see some of these problems so here

390
00:20:55.370 --> 00:20:55.980
we've

391
00:20:55.980 --> 00:21:01.310
got neutral we've got no real hip trigger so that wasn't just discussed by

392
00:21:01.310 --> 00:21:02.260
anybody but

393
00:21:02.260 --> 00:21:06.170
that can be a sign that they're not really using their legs so one of the

394
00:21:06.170 --> 00:21:06.820
things that

395
00:21:06.820 --> 00:21:12.150
I've seen is when you're when you're doing a proper you're doing a proper squat

396
00:21:12.150 --> 00:21:12.500
you're

397
00:21:12.500 --> 00:21:18.520
going to tend to maintain this arch in your lower back so oftentimes golfers

398
00:21:18.520 --> 00:21:19.380
who never

399
00:21:19.380 --> 00:21:23.740
get any of this tilt aren't really pushing against the ground very hard with

400
00:21:23.740 --> 00:21:24.400
their lower

401
00:21:24.400 --> 00:21:30.850
body so this would be a golfer who would be pushing primarily with the upper

402
00:21:30.850 --> 00:21:31.740
body and

403
00:21:31.740 --> 00:21:41.270
shoulders as opposed to using the core okay so here he goes as we go up to the

404
00:21:41.270 --> 00:21:41.860
top of

405
00:21:41.860 --> 00:21:47.540
the swing this is usually the view where you'd see a little bit more from that

406
00:21:47.540 --> 00:21:48.700
hip tilt

407
00:21:48.700 --> 00:21:53.110
and you can see he's using his lower body sound but he's not pushing very much

408
00:21:53.110 --> 00:21:53.940
vertically

409
00:21:53.940 --> 00:21:59.210
it's kind of more of a spin and if you look at that lower back there's no real

410
00:21:59.210 --> 00:22:00.100
increased

411
00:22:00.100 --> 00:22:05.140
arch if you compare that to see it say Steve Elkington you'll see a lot more of

412
00:22:05.140 --> 00:22:05.380
it so

413
00:22:05.380 --> 00:22:12.020
just to help you visualize that here's Steve Elkington slumograph kind of right

414
00:22:12.020 --> 00:22:12.780
in there

415
00:22:12.780 --> 00:22:16.790
right there if you look at the belt buckle you can see it dip down that's that

416
00:22:16.790 --> 00:22:17.500
excessive

417
00:22:17.500 --> 00:22:21.850
trigger so it looks pretty subtle and it looks like oh man it's really

418
00:22:21.850 --> 00:22:23.100
happening just up

419
00:22:23.100 --> 00:22:29.680
there yes remember halfway through the graph is here so if it's in that first

420
00:22:29.680 --> 00:22:30.720
quarter where

421
00:22:30.720 --> 00:22:35.300
we saw that excessive movement it's really looking at these kind of micro

422
00:22:35.300 --> 00:22:37.100
movements here

423
00:22:37.100 --> 00:22:44.130
in transition okay another amateur pattern nothing too descriptive maybe a

424
00:22:44.130 --> 00:22:45.300
little loss

425
00:22:45.300 --> 00:22:53.000
of posture going on there but then good hips trigger as well as nice posterior

426
00:22:53.000 --> 00:22:53.740
tilt and

427
00:22:53.740 --> 00:23:00.710
then here would be another example let's look at Ron okay so we're gonna look

428
00:23:00.710 --> 00:23:01.500
at Ron

429
00:23:01.500 --> 00:23:05.910
keep this in the back of our mind so is he posterior tilting a ton in the back

430
00:23:05.910 --> 00:23:06.380
swing

431
00:23:06.380 --> 00:23:16.670
is that what is that what's happening well you can probably see there's some

432
00:23:16.670 --> 00:23:18.060
loss of posture

433
00:23:18.060 --> 00:23:23.620
so his upper body starts moving away from the golf ball and the belt line gets

434
00:23:23.620 --> 00:23:24.220
pretty

435
00:23:24.220 --> 00:23:31.240
vertical he does have a little bit of increase through there and then pretty

436
00:23:31.240 --> 00:23:32.660
big posterior

437
00:23:32.660 --> 00:23:38.980
tilt going on through there so there you can see the graph right about that's

438
00:23:38.980 --> 00:23:39.340
probably

439
00:23:39.340 --> 00:23:46.380
about the same time where he's almost bending backward right through there okay

440
00:23:46.380 --> 00:23:47.900
so now looking

441
00:23:47.900 --> 00:23:54.370
at the side bend graph side bend graph is usually pretty simple near zero at

442
00:23:54.370 --> 00:23:55.140
setup 10

443
00:23:55.140 --> 00:23:59.340
degrees roughly 10 degrees bent to the left at the top roughly 10 degrees bent

444
00:23:59.340 --> 00:23:59.620
to the

445
00:23:59.620 --> 00:24:04.740
right at impact and you want to look for kind of the side bent side bend

446
00:24:04.740 --> 00:24:06.260
plateau somewhere

447
00:24:06.260 --> 00:24:18.060
around impact that's kind of a sign of a stable lead leg okay so with with this

448
00:24:18.060 --> 00:24:18.060
the

449
00:24:18.060 --> 00:24:22.680
key anatomical structures again looking at the hip looking at the knee looking

450
00:24:22.680 --> 00:24:22.900
at the

451
00:24:22.900 --> 00:24:26.900
ankle when we're looking at the hip which has the biggest influence on this it

452
00:24:26.900 --> 00:24:27.780
's primarily

453
00:24:27.780 --> 00:24:34.820
looking at the lateral slings are looking at the adductors connecting to the ob

454
00:24:34.820 --> 00:24:35.540
liques

455
00:24:35.540 --> 00:24:42.590
or the glute medius in their reference to the lower back or QLO quadratus lumb

456
00:24:42.590 --> 00:24:43.260
orum so

457
00:24:43.260 --> 00:24:48.210
rotational slings versus lateral slings the TPI errors that they talk about

458
00:24:48.210 --> 00:24:48.740
with this

459
00:24:48.740 --> 00:24:57.570
would be either the trail hip too high so seeing kind of excessive the number

460
00:24:57.570 --> 00:24:58.780
starting

461
00:24:58.780 --> 00:25:04.740
with the trail hip kind of like this especially with the driver that kind of

462
00:25:04.740 --> 00:25:06.120
biases everything

463
00:25:06.120 --> 00:25:12.080
forward and causes golfers to get steep or this is one you want to be really

464
00:25:12.080 --> 00:25:12.780
careful

465
00:25:12.780 --> 00:25:17.920
with they talk about sway so we're going to look at one example one of our

466
00:25:17.920 --> 00:25:19.220
three amateurs

467
00:25:19.220 --> 00:25:26.090
that's going to make you just be careful with just using side bend to diagnose

468
00:25:26.090 --> 00:25:28.820
sway but especially

469
00:25:28.820 --> 00:25:33.400
looking at side bend has a big impact on the steep shallows so getting some of

470
00:25:33.400 --> 00:25:34.060
this pelvis

471
00:25:34.060 --> 00:25:40.020
tilt is a big shallow movement or creating axis tilt if they lack that you want

472
00:25:40.020 --> 00:25:40.500
to look

473
00:25:40.500 --> 00:25:45.260
at well how are they controlling the club face and are they getting you know

474
00:25:45.260 --> 00:25:45.460
are they

475
00:25:45.460 --> 00:25:50.170
staying in their posture and rotating to balance out having side bend or having

476
00:25:50.170 --> 00:25:50.540
more

477
00:25:50.540 --> 00:25:57.590
of say a lunge or early extension loss of posture pattern so here's grant

478
00:25:57.590 --> 00:25:58.300
weight you've

479
00:25:58.300 --> 00:26:04.970
got starting with trail hip maybe just a tiny bit high that could have been a

480
00:26:04.970 --> 00:26:06.180
digitizing

481
00:26:06.180 --> 00:26:12.630
issue but it looks pretty good there so I'm guessing not so if this is taken

482
00:26:12.630 --> 00:26:13.500
around the

483
00:26:13.500 --> 00:26:16.700
time that that 3D was collected and you can see this was you know he was

484
00:26:16.700 --> 00:26:17.540
experimenting

485
00:26:17.540 --> 00:26:20.850
a little bit more with maybe stacking tilt and you can see that trail hip is

486
00:26:20.850 --> 00:26:21.620
just a little

487
00:26:21.620 --> 00:26:28.590
bit high there's the 15 degree tilt and then boom you can see a little bit of

488
00:26:28.590 --> 00:26:29.540
that side

489
00:26:29.540 --> 00:26:33.830
tilt especially down through there right through there is that stable plateau

490
00:26:33.830 --> 00:26:34.580
where you tend

491
00:26:34.580 --> 00:26:41.220
to see the hips kind of almost stabilize so good looking move okay now we got

492
00:26:41.220 --> 00:26:41.680
Henrik

493
00:26:41.680 --> 00:26:46.430
Stenson his starts with a little bit more tilt but remember Henrik has that

494
00:26:46.430 --> 00:26:46.980
kind of

495
00:26:46.980 --> 00:26:51.760
interesting trigger so this address position is when the club starts back and

496
00:26:51.760 --> 00:26:52.500
he does that

497
00:26:52.500 --> 00:26:56.740
kind of pre or that sit into that right side before the club starts back so

498
00:26:56.740 --> 00:26:57.500
that could

499
00:26:57.500 --> 00:27:03.460
bias this movement a little light on the side bend in the backswing but then a

500
00:27:03.460 --> 00:27:04.340
little heavy

501
00:27:04.340 --> 00:27:10.640
on the side bend in the downswing so again this could have been a pelvis digit

502
00:27:10.640 --> 00:27:11.460
ization

503
00:27:11.460 --> 00:27:20.080
issue as well but let's take a quick look so here's where prior to taking it

504
00:27:20.080 --> 00:27:21.100
back everything

505
00:27:21.100 --> 00:27:25.580
looks good club still hasn't moved club still hasn't moved club still hasn't

506
00:27:25.580 --> 00:27:26.140
moved there

507
00:27:26.140 --> 00:27:34.110
the club moves so this is where it's referencing his starting position so it

508
00:27:34.110 --> 00:27:35.820
looks like he's

509
00:27:35.820 --> 00:27:40.590
probably tilted a little bit more that's why that red high this will really

510
00:27:40.590 --> 00:27:41.220
show up when

511
00:27:41.220 --> 00:27:46.620
we're looking at some of his sway numbers but you got to keep the how the

512
00:27:46.620 --> 00:27:47.460
system is

513
00:27:47.460 --> 00:27:53.620
measuring addresses when the club moves so all that does not count as a dress

514
00:27:53.620 --> 00:27:54.220
and then

515
00:27:54.220 --> 00:28:02.200
we've got elk who's got a little bit of kind of a not as much of the plateau

516
00:28:02.200 --> 00:28:03.380
but overall

517
00:28:03.380 --> 00:28:07.960
good pattern maybe a little bit tilted only a couple degrees not too bad let's

518
00:28:07.960 --> 00:28:08.460
look at

519
00:28:08.460 --> 00:28:16.030
some of the errors okay so side bend problems you can see issues with the foot

520
00:28:16.030 --> 00:28:18.140
loading or

521
00:28:18.140 --> 00:28:25.230
possibly using the side bend if they aren't getting into like basically how

522
00:28:25.230 --> 00:28:26.520
they're balancing

523
00:28:26.520 --> 00:28:30.420
their steeps in shallow so side bend is one of the big shallow movements it

524
00:28:30.420 --> 00:28:30.780
shifts the

525
00:28:30.780 --> 00:28:35.400
path to the right it moves the low point backward so you have to have things

526
00:28:35.400 --> 00:28:36.540
that balance that

527
00:28:36.540 --> 00:28:41.480
element otherwise you're going to hit a lot of fat thin shots if you just added

528
00:28:41.480 --> 00:28:42.180
more side

529
00:28:42.180 --> 00:28:47.880
bend without adding something else so downswing problems looking at excessive

530
00:28:47.880 --> 00:28:48.860
axis tilt maybe

531
00:28:48.860 --> 00:28:54.820
helping kind of you know to shallow mostly with the body if my arms aren't shaw

532
00:28:54.820 --> 00:28:55.500
ling it

533
00:28:55.500 --> 00:28:59.400
can also get me into position to kind of fling the club closed if I have a club

534
00:28:59.400 --> 00:29:01.580
taste issue

535
00:29:01.580 --> 00:29:05.480
oftentimes golfers who kind of like pull down a lot with their arms get into

536
00:29:05.480 --> 00:29:06.140
this side bend

537
00:29:06.140 --> 00:29:12.570
movement so it's steep arm shallow body if I get steep arms in transition or a

538
00:29:12.570 --> 00:29:13.540
lack of

539
00:29:13.540 --> 00:29:20.430
verticals late so if I'm you know approaching the release and kind of staying

540
00:29:20.430 --> 00:29:21.420
in more of

541
00:29:21.420 --> 00:29:26.910
a buckle kind of like this or if I have a lot of shoulder throw action this

542
00:29:26.910 --> 00:29:27.780
side bend

543
00:29:27.780 --> 00:29:32.730
movement can help kind of tilt the plane so that I'll get a little bit more of

544
00:29:32.730 --> 00:29:33.220
a flat

545
00:29:33.220 --> 00:29:38.990
spot but that can cause some low point issues especially with your shorter ir

546
00:29:38.990 --> 00:29:41.340
ons so here

547
00:29:41.340 --> 00:29:49.420
we'll see Ron having close to 20 degrees of tilt so by TPI they'd be saying hey

548
00:29:49.420 --> 00:29:49.620
that's

549
00:29:49.620 --> 00:29:56.000
a pretty big sway so here's what 20 degrees of side bend looks like he throws

550
00:29:56.000 --> 00:29:56.780
me off with

551
00:29:56.780 --> 00:30:03.480
his little waggle this is okay don't sway watch him kick that knee in oh boom

552
00:30:03.480 --> 00:30:05.660
big sway

553
00:30:05.660 --> 00:30:11.050
from the face on view it doesn't look too dramatic let's peek in from the down

554
00:30:11.050 --> 00:30:13.820
the line view

555
00:30:13.820 --> 00:30:17.900
so right about now is when he goes into that sway that's a pretty significant

556
00:30:17.900 --> 00:30:18.540
tilt there

557
00:30:18.540 --> 00:30:31.720
to the left so then we see that he doesn't really stabilize until well after

558
00:30:31.720 --> 00:30:32.620
impact let's

559
00:30:32.620 --> 00:30:41.380
see what that looks like so as he goes through he's going into some side bend

560
00:30:41.380 --> 00:30:42.500
there I think

561
00:30:42.500 --> 00:30:49.720
that's actually going to show up better from this down the line so you'll see

562
00:30:49.720 --> 00:30:50.500
boom that

563
00:30:50.500 --> 00:30:56.060
little buckle right there that's where we see the continued increase side bend

564
00:30:56.060 --> 00:30:56.620
number

565
00:30:56.620 --> 00:31:02.170
right through there that's where this continue where it doesn't really plateau

566
00:31:02.170 --> 00:31:03.300
or stabilize

567
00:31:03.300 --> 00:31:11.280
that impact okay so we got Colin limited you know a little bit of tilt there

568
00:31:11.280 --> 00:31:12.220
and then

569
00:31:12.220 --> 00:31:17.370
no real plateau until after impact let's see typically down the line is a

570
00:31:17.370 --> 00:31:18.220
little bit

571
00:31:18.220 --> 00:31:25.980
easier for seeing this so it's a little hard to see there because of his shirt

572
00:31:25.980 --> 00:31:26.380
creating

573
00:31:26.380 --> 00:31:33.950
this angle but see how as he comes how quickly his hips are level that's a sign

574
00:31:33.950 --> 00:31:34.180
that there

575
00:31:34.180 --> 00:31:46.070
wasn't much tilt and then on the way through let's see that from the face on so

576
00:31:46.070 --> 00:31:46.460
you can

577
00:31:46.460 --> 00:31:51.560
see how how much that left hip kind of goes up he's up on his tippy toes this

578
00:31:51.560 --> 00:31:52.180
left hip

579
00:31:52.180 --> 00:31:59.350
comes up as that knee stays bent that's what creates this side bend look so

580
00:31:59.350 --> 00:32:00.700
this is one

581
00:32:00.700 --> 00:32:05.390
it can be a little hard to see just looking at video so having the graph I

582
00:32:05.390 --> 00:32:06.860
think is definitely

583
00:32:06.860 --> 00:32:12.820
helpful but again you don't want to overreact when you're just looking at one

584
00:32:12.820 --> 00:32:13.380
individual

585
00:32:13.380 --> 00:32:21.350
graph okay so we got Mike here a little let little trail hip high big plateau

586
00:32:21.350 --> 00:32:22.060
here at

587
00:32:22.060 --> 00:32:27.290
the top of swing we'll see what that looks like and then kind of limited tilt

588
00:32:27.290 --> 00:32:28.220
but plateau

589
00:32:28.220 --> 00:32:38.410
as we go through all right so here's Mike so the plateau is basically right in

590
00:32:38.410 --> 00:32:39.020
all through

591
00:32:39.020 --> 00:32:43.380
there there's not much pelvis movement whatsoever and then as he goes through

592
00:32:43.380 --> 00:32:44.260
you can see how

593
00:32:44.260 --> 00:32:48.770
much more those hips are pretty level partly because of how much early

594
00:32:48.770 --> 00:32:50.140
extension he's had

595
00:32:50.140 --> 00:32:55.510
on the way through okay last one looking at the rotational graphs basically

596
00:32:55.510 --> 00:32:56.420
this is the

597
00:32:56.420 --> 00:33:01.750
rotation graphs according to TPI we'll get to are some of the more boring ones

598
00:33:01.750 --> 00:33:02.940
near zero

599
00:33:02.940 --> 00:33:07.410
it's set up about 45 degrees at the top change direction before the top of the

600
00:33:07.410 --> 00:33:08.100
swing because

601
00:33:08.100 --> 00:33:11.060
the top of the swing is defined as when the club changes direction so you want

602
00:33:11.060 --> 00:33:11.500
the pelvis

603
00:33:11.500 --> 00:33:16.080
to move before the club and then about 40 degrees open 30 degrees open

604
00:33:16.080 --> 00:33:16.940
somewhere in

605
00:33:16.940 --> 00:33:24.920
there at impact so here's some of those numbers again thinking about well what

606
00:33:24.920 --> 00:33:25.420
's rotating

607
00:33:25.420 --> 00:33:29.620
the pelvis is the movement happening from the feet from the knees from the hips

608
00:33:29.620 --> 00:33:29.940
more

609
00:33:29.940 --> 00:33:35.250
from the thoracic spine what's pulling the pelvis into its movement the big

610
00:33:35.250 --> 00:33:36.000
rotation

611
00:33:36.000 --> 00:33:42.610
muscles the lat the obliques and transverse or spinalis are the big two so this

612
00:33:42.610 --> 00:33:43.080
is again

613
00:33:43.080 --> 00:33:49.480
looking at these spiral lines or the rotational slings versus more your chop or

614
00:33:49.480 --> 00:33:50.380
lateral or

615
00:33:50.380 --> 00:34:00.460
crunch slings this is related to kind of our major concepts of body versus arms

616
00:34:00.460 --> 00:34:01.140
and the

617
00:34:01.140 --> 00:34:08.620
associating movements TPI says that there's no errors unless a golfer basically

618
00:34:08.620 --> 00:34:09.440
adds fake

619
00:34:09.440 --> 00:34:15.590
rotation and creates an error in trying to do so so we got grant weight starts

620
00:34:15.590 --> 00:34:15.960
around

621
00:34:15.960 --> 00:34:25.830
zero about 45 about 40 pretty boring Henrich Sensen close to zero about 45

622
00:34:25.830 --> 00:34:28.480
about 40 this

623
00:34:28.480 --> 00:34:34.180
is changing direction before top of the swing these ones look pretty boring

624
00:34:34.180 --> 00:34:37.260
usually okay

625
00:34:37.260 --> 00:34:40.740
change direction is closer to the top of the swing than some of the others so

626
00:34:40.740 --> 00:34:41.300
Elkington

627
00:34:41.300 --> 00:34:45.970
might have more of a look of kind of everything collecting see what that looks

628
00:34:45.970 --> 00:34:47.100
like okay so

629
00:34:47.100 --> 00:34:53.070
if we go up to the top of the swing the club changing directions are right

630
00:34:53.070 --> 00:34:55.380
there so the

631
00:34:55.380 --> 00:35:00.210
lower body is kind of like waiting to rotate until closer to when the club

632
00:35:00.210 --> 00:35:01.600
changes direction

633
00:35:01.600 --> 00:35:06.990
remember all this stuff is happening just in this little little window of time

634
00:35:06.990 --> 00:35:07.600
so when

635
00:35:07.600 --> 00:35:13.640
you're scrubbing and looking for this stuff want to get used to looking for how

636
00:35:13.640 --> 00:35:14.560
the joints

637
00:35:14.560 --> 00:35:20.520
are moving in this small little window okay so the main things you'll see here

638
00:35:20.520 --> 00:35:20.960
will be

639
00:35:20.960 --> 00:35:25.430
limitations in the absolute value you won't see a huge change in the pattern

640
00:35:25.430 --> 00:35:26.100
you might

641
00:35:26.100 --> 00:35:31.660
see a timing difference so compared to the top of the swing swing related

642
00:35:31.660 --> 00:35:32.680
issues back

643
00:35:32.680 --> 00:35:36.750
swing looking at are they loading the foot or are they swaying the knee is

644
00:35:36.750 --> 00:35:37.500
there a lot

645
00:35:37.500 --> 00:35:42.120
of arm lift a lot of hinging the trail arm kind of going external all those

646
00:35:42.120 --> 00:35:42.820
will tend

647
00:35:42.820 --> 00:35:46.880
to limit rotation looking at neck rotation I don't have a list of there but

648
00:35:46.880 --> 00:35:47.560
looking at

649
00:35:47.560 --> 00:35:52.140
neck rotation can be a big limit on the body's ability to rotate and then if

650
00:35:52.140 --> 00:35:52.960
you're seeing

651
00:35:52.960 --> 00:35:57.220
issues in the down swing is the trail arm straightening in my early extending

652
00:35:57.220 --> 00:35:57.760
or losing

653
00:35:57.760 --> 00:36:01.720
posture or did I get steep as the club face open all of those will limit my

654
00:36:01.720 --> 00:36:02.440
ability to

655
00:36:02.440 --> 00:36:08.140
rotate so again TPI says there's no real rotation errors it's just how much

656
00:36:08.140 --> 00:36:08.880
they're

657
00:36:08.880 --> 00:36:14.840
capable but then how is the golfer creating speed are we maintaining posture is

658
00:36:14.840 --> 00:36:15.120
there

659
00:36:15.120 --> 00:36:21.480
good stability of the lower body and in the kinematic sequence what's the peak

660
00:36:21.480 --> 00:36:21.920
order look

661
00:36:21.920 --> 00:36:29.250
like classic stuff starts around zero changes direction before the top we

662
00:36:29.250 --> 00:36:30.360
excessive you

663
00:36:30.360 --> 00:36:39.350
know 60 degrees of rotation there and then light on impact so here we go that's

664
00:36:39.350 --> 00:36:39.400
that

665
00:36:39.400 --> 00:36:45.360
excessive that's a lot of hip rotation 60 degrees and then there we can see it

666
00:36:45.360 --> 00:36:45.680
impact

667
00:36:45.680 --> 00:36:52.240
that's what 20 degrees of hip rotation looks like not very much and you can see

668
00:36:52.240 --> 00:36:52.960
that he's

669
00:36:52.960 --> 00:36:58.920
got a little bit of trail arm straightening early he's definitely got some

670
00:36:58.920 --> 00:37:00.120
early extension

671
00:37:00.120 --> 00:37:07.880
that's stalling some of the rotation not too bad with some of the other pieces

672
00:37:07.880 --> 00:37:09.260
but

673
00:37:09.260 --> 00:37:15.460
excessive rotation in the backswing coupled with under rotation in the down

674
00:37:15.460 --> 00:37:16.180
swing okay

675
00:37:16.180 --> 00:37:22.770
so we got Colin now let's minimize that a little bit good so he's starting 12

676
00:37:22.770 --> 00:37:23.280
degrees

677
00:37:23.280 --> 00:37:28.740
open that could possibly be he was aiming at something different than the

678
00:37:28.740 --> 00:37:29.580
tripod but

679
00:37:29.580 --> 00:37:37.280
limited in the backswing and then good amount of rotation in the downswing so

680
00:37:37.280 --> 00:37:38.580
we can see

681
00:37:38.580 --> 00:37:41.350
all right not too worried about 12 degrees open he was just probably aimed

682
00:37:41.350 --> 00:37:41.800
different

683
00:37:41.800 --> 00:37:51.360
from the tripod so that 12 degrees means he was probably closer to 3540 which

684
00:37:51.360 --> 00:37:51.740
is still

685
00:37:51.740 --> 00:38:00.730
a little under rotated maybe that would show up more from the face on view so

686
00:38:00.730 --> 00:38:01.740
little under

687
00:38:01.740 --> 00:38:06.400
rotated with what's going on in the pelvis but then we saw plenty of rotation

688
00:38:06.400 --> 00:38:06.840
in the

689
00:38:06.840 --> 00:38:14.180
downswing yep so seeing the classic two cheek position or seeing the left leg

690
00:38:14.180 --> 00:38:15.580
that's decent

691
00:38:15.580 --> 00:38:21.180
rotation there so he's close to 40 degrees not too bad you know here's the

692
00:38:21.180 --> 00:38:22.820
target there's

693
00:38:22.820 --> 00:38:28.780
kind of 40 45 degree angle last one we got mics that's a pretty neutral little

694
00:38:28.780 --> 00:38:29.700
under rotated

695
00:38:29.700 --> 00:38:35.660
maybe change his direction before the top of the swing that's fine and then

696
00:38:35.660 --> 00:38:37.600
decent position

697
00:38:37.600 --> 00:38:43.860
there at impact oh here we go little under rotated there at the top of the

698
00:38:43.860 --> 00:38:45.640
swing but then

699
00:38:45.640 --> 00:38:51.410
you can see you know that's in that 35 40 degree yeah it's probably about where

700
00:38:51.410 --> 00:38:51.740
he's

701
00:38:51.740 --> 00:38:58.290
added impact so it's not pointing at the ball but it's not open say as much as

702
00:38:58.290 --> 00:38:58.680
some

703
00:38:58.680 --> 00:39:06.010
of the twerpros again the the angles are some of the more boring graphs there's

704
00:39:06.010 --> 00:39:06.340
not

705
00:39:06.340 --> 00:39:10.340
going to be some major differences the way we'll see with the liniers and with

706
00:39:10.340 --> 00:39:10.800
the wrist

707
00:39:10.800 --> 00:39:16.760
graphs okay so here's what it looks like again these are three pros lots of

708
00:39:16.760 --> 00:39:17.240
similarities

709
00:39:17.240 --> 00:39:23.440
there and then here's your three amateurs little less clean you'll see little

710
00:39:23.440 --> 00:39:24.080
things

711
00:39:24.080 --> 00:39:30.320
like okay longer flat lines not quite as big scale but overall they typically

712
00:39:30.320 --> 00:39:31.040
have close

713
00:39:31.040 --> 00:39:34.200
to the same patterns you're looking for some of these details okay so hopefully

714
00:39:34.200 --> 00:39:34.640
this helps

715
00:39:34.640 --> 00:39:38.990
clear up what's going on with the pelvis angles graphs enjoy the rest of the 3d

716
00:39:38.990 --> 00:39:39.920
presentations

717
00:39:39.920 --> 00:39:43.820
to figure out how each segment is moving and how it relates to the overall

718
00:39:43.820 --> 00:39:44.920
system of movement

719
00:39:44.920 --> 00:39:46.160
for your golfer's golf swings.
