Pelvis Positions

WEBVTT

1
00:00:00.000 --> 00:00:05.960
All right coaches, here we go again. Let's take a look at the first of the

2
00:00:05.960 --> 00:00:11.580
position graph. So in the first couple videos we were looking mostly at the

3
00:00:11.580 --> 00:00:16.560
rotations. Now we're looking at the linear movement. So you got side to side,

4
00:00:16.560 --> 00:00:22.760
up and down, and then forward, backward. In combination that gives you all six

5
00:00:22.760 --> 00:00:27.080
degrees of movement that a body can make in 3D space. So we're gonna dig into

6
00:00:27.080 --> 00:00:27.360
the

7
00:00:27.360 --> 00:00:32.680
patterns we see on this graph here. Okay, as with all these presentations we're

8
00:00:32.680 --> 00:00:38.360
going to take a look at the examples of tour swings or good patterns as well as

9
00:00:38.360 --> 00:00:43.160
amateurs or bad patterns. We're gonna look at the TPI and AMM guidelines and I

10
00:00:43.160 --> 00:00:43.240
'll

11
00:00:43.240 --> 00:00:48.360
layer in kind of my observations and we're gonna start by talking about the

12
00:00:48.360 --> 00:00:55.240
related anatomy and movement concepts that are associated with the graphs. So

13
00:00:55.240 --> 00:01:02.960
with this we're looking at pelvis way, pelvis thrust, pelvis lift. So sway is

14
00:01:02.960 --> 00:01:03.160
the

15
00:01:03.160 --> 00:01:08.480
side-to-side motion towards and away the target. Thrust is towards or away from

16
00:01:08.480 --> 00:01:15.760
the golf ball, so early extension, and then lift is up and down. Now when it

17
00:01:15.760 --> 00:01:19.920
comes to this, when it comes to the linear movements you have to be really

18
00:01:19.920 --> 00:01:27.120
careful at looking at if the data was digitized or not. So I remember when we

19
00:01:27.120 --> 00:01:32.160
had our first 3D system at club golf, it did not digitize. It was just a snap

20
00:01:32.160 --> 00:01:38.560
alignment and the sway numbers and the early extension numbers were really hard

21
00:01:38.560 --> 00:01:43.800
to interpret. I remember having a lot of trouble with that and here's why. So

22
00:01:43.800 --> 00:01:44.600
let's

23
00:01:44.600 --> 00:01:49.800
say that this is, let's say that we're looking at this object here, we're gonna

24
00:01:49.800 --> 00:01:54.760
this is our pelvis, we're looking at it from top down and then I put the sensor

25
00:01:54.760 --> 00:02:02.320
on the body just like this. Well if I'm measuring right here and I rotate you

26
00:02:02.320 --> 00:02:02.480
can

27
00:02:02.480 --> 00:02:09.880
see as I rotate this moves some amount that way. So it goes like that. Well the

28
00:02:09.880 --> 00:02:15.120
more I rotate the more that might move. Well trying to figure out how much was

29
00:02:15.120 --> 00:02:20.800
this and how much was that, proves to be very difficult. So when they digitize

30
00:02:20.800 --> 00:02:25.730
they're trying to measure from closer to the center. So now when this rotates

31
00:02:25.730 --> 00:02:26.000
it

32
00:02:26.000 --> 00:02:29.760
doesn't really move and when it translates it's, we know it's

33
00:02:29.760 --> 00:02:36.080
translation. So that's why for example when you see the sway numbers promoted

34
00:02:36.080 --> 00:02:41.200
by golf tech, they'll talk about shifting you know three to six inches

35
00:02:41.200 --> 00:02:44.040
towards the target or things like that. A lot of it is because of the snap

36
00:02:44.040 --> 00:02:51.400
alignment that they use. So you just have to be careful with how the data is

37
00:02:51.400 --> 00:02:57.960
collected and measured. In this case especially for the linear, it's tougher.

38
00:02:57.960 --> 00:03:01.680
And inertial sensors are really good at getting angles accurately but they have

39
00:03:01.680 --> 00:03:05.080
a hard time with the linear. So that's why a lot of the simpler systems

40
00:03:05.080 --> 00:03:05.680
currently

41
00:03:05.680 --> 00:03:11.520
you get mostly the angles but what we saw from the angle presentations is those

42
00:03:11.520 --> 00:03:17.370
are maybe not quite as clear as what we're going to see in this one. Okay so we

43
00:03:17.370 --> 00:03:17.520
'll

44
00:03:17.520 --> 00:03:23.760
jump through the three graphs. Pelvic positions here we've got the timeline of

45
00:03:23.760 --> 00:03:29.240
the golf swing so address top impact finish. Red line is pelvis sway in this

46
00:03:29.240 --> 00:03:35.400
case. Green line is pelvis thrust towards and away and then blue line is

47
00:03:35.400 --> 00:03:42.960
pelvis lift. And here we have so that was Henrik Stenson. Henrik Stenson will

48
00:03:42.960 --> 00:03:48.640
we'll look at some of his details. A big part of what makes his look odd is the

49
00:03:48.640 --> 00:03:55.440
setup kind of trigger the sway movement that he does. But you will see that it

50
00:03:55.440 --> 00:04:00.840
doesn't really influence the other two graphs just this this way is. Okay same

51
00:04:00.840 --> 00:04:06.360
thing. So here we have Grant weight. Pretty classic pattern we'll talk about

52
00:04:06.360 --> 00:04:09.760
some of the details but a lot of you know if you study this one you'll

53
00:04:09.760 --> 00:04:17.640
understand some of the basics. Elkington little little different than both

54
00:04:17.640 --> 00:04:21.680
Henrik and Grant weight we'll talk especially in the lift graph we'll talk

55
00:04:21.680 --> 00:04:27.080
about that. But we can see if we put the three of them up there and we just

56
00:04:27.080 --> 00:04:27.240
kind

57
00:04:27.240 --> 00:04:31.480
of take a step back and look at them from a distance you will see there's some

58
00:04:31.480 --> 00:04:37.600
general patterns you got kind of this green and blue kind of one up one down

59
00:04:37.600 --> 00:04:42.920
on top of each other kind of like that meeting here around impact and you got

60
00:04:42.920 --> 00:04:48.790
the red line kind of flat up flat so you got some similarities there we'll we

61
00:04:48.790 --> 00:04:49.080
'll

62
00:04:49.080 --> 00:04:54.010
see if that carries over when we look at the amateurs. But and we'll dig into

63
00:04:54.010 --> 00:04:54.080
the

64
00:04:54.080 --> 00:04:59.360
details of each one of these graphs. Okay just a quick reminder on the 3D

65
00:04:59.360 --> 00:05:03.970
guidelines at this point hopefully you've you've got my stance on it that 3D

66
00:05:03.970 --> 00:05:04.080
does

67
00:05:04.080 --> 00:05:08.080
not give you 100 percent answers it just tells you what to focus on so that you

68
00:05:08.080 --> 00:05:12.520
can like connect what the graph is showing to the movements that they're

69
00:05:12.520 --> 00:05:18.360
making. Never only look at one graph I advocate looking at video as well as the

70
00:05:18.360 --> 00:05:23.560
graphs because you can see things on video and you can see things on graphs

71
00:05:23.560 --> 00:05:28.540
they kind of provide different information but if you just look at one

72
00:05:28.540 --> 00:05:33.560
graph you might miss the system as a whole and that one thing that might look

73
00:05:33.560 --> 00:05:37.240
funny on that one graph might be the key movement for them that's holding

74
00:05:37.240 --> 00:05:41.920
their swing together so if you randomly choose stuff you're you're in trouble

75
00:05:41.920 --> 00:05:48.960
always think in movement rather than kind of absolutes for these graphs or

76
00:05:48.960 --> 00:05:53.960
absolutes for you know whether it's called face numbers or whatever like

77
00:05:53.960 --> 00:05:59.040
always think is in movement and and how you're going to kind of massage or

78
00:05:59.040 --> 00:06:03.360
adjust the swing rather than just there's an absolute perfect number I'm

79
00:06:03.360 --> 00:06:04.080
chasing

80
00:06:04.080 --> 00:06:12.720
okay what's moving what's not again the the big ones here are this gives a time

81
00:06:12.720 --> 00:06:17.200
3D graph gives a timeline of the golf swing so you can see kind of all the

82
00:06:17.200 --> 00:06:22.240
phases all at once and when you have all the graphs up you can kind of really

83
00:06:22.240 --> 00:06:29.360
look at it relationship wise you can see how each graph is moving at the same

84
00:06:29.360 --> 00:06:34.240
time as the other graphs but it's easier on video to kind of find the fix point

85
00:06:34.240 --> 00:06:39.200
but 3D will show kind of plateaus where things are stabilizing so some good

86
00:06:39.200 --> 00:06:44.400
stuff here probably won't get you with 3D you don't get into as many of the

87
00:06:44.400 --> 00:06:49.560
little details that we will with the video but it's really good at kind of

88
00:06:49.560 --> 00:06:55.920
putting a person or a golfer in them in the key box that they need to hopefully

89
00:06:55.920 --> 00:07:03.240
improve okay we're gonna be talking most are all about the pelvis in this class

90
00:07:03.240 --> 00:07:08.680
so keep in mind the anatomy around the pelvis we're gonna look at just a quick

91
00:07:08.680 --> 00:07:14.240
little refresher on the hip muscles or the hip joints are gonna have a big

92
00:07:14.240 --> 00:07:18.160
influence the lower back is gonna have a big influence but also the knee and

93
00:07:18.160 --> 00:07:18.400
hip

94
00:07:18.400 --> 00:07:24.040
but the big muscles around the around the pelvis you know your abs your low

95
00:07:24.040 --> 00:07:24.320
back

96
00:07:24.320 --> 00:07:29.870
your QL your lats your glutes all the leg muscles your adductors quads ham

97
00:07:29.870 --> 00:07:30.280
strings

98
00:07:30.280 --> 00:07:38.760
so as all these guys are integral in trying to move this area from a joint

99
00:07:38.760 --> 00:07:44.600
perspective the hip the pelvis has kind of little micro movements that will

100
00:07:44.600 --> 00:07:49.840
change which facial link is being worked and how stresses being absorbed but

101
00:07:49.840 --> 00:07:49.960
the

102
00:07:49.960 --> 00:07:54.680
bigger movements are gonna happen at the hip joint and the spine so the pelvis

103
00:07:54.680 --> 00:07:54.840
is

104
00:07:54.840 --> 00:08:01.720
just caught right in between and we usually put the sensor on kind of a

105
00:08:01.720 --> 00:08:08.720
flat spot around the sacrum but you'll digitize the the hip joint so it doesn't

106
00:08:08.720 --> 00:08:15.280
matter exactly if this sensor is a hundred percent in the right spot anyway the

107
00:08:15.280 --> 00:08:20.680
the hip has you know it's ball and socket it's got multi planes movement so

108
00:08:20.680 --> 00:08:26.920
flexion extension in and out abduction edit adduction which isn't shown here

109
00:08:26.920 --> 00:08:33.320
which is about the same or a little bit more actually and then you've got

110
00:08:33.320 --> 00:08:39.560
internal and external rotation with the pelvis itself you've got mostly

111
00:08:39.560 --> 00:08:40.840
posterior

112
00:08:40.840 --> 00:08:48.600
and anterior tilt the pelvis works in a micro movement scale kind of on this

113
00:08:48.600 --> 00:08:52.920
oblique axis but the pelvis isn't moving a ton it's more the hip socket and the

114
00:08:52.920 --> 00:08:59.880
spine that are rotating when you're thinking relationship wise though let's

115
00:08:59.880 --> 00:09:04.680
make this a little bit bigger for you guys so when you're thinking relationship

116
00:09:04.680 --> 00:09:10.240
wise there's all these integrated movements so the classic patterns you

117
00:09:10.240 --> 00:09:15.200
can break these patterns but the classic pattern is the foot rolls in the tibia

118
00:09:15.200 --> 00:09:18.980
rolls in the hip rolls in so the pelvis tips forward that's how you get s

119
00:09:18.980 --> 00:09:19.400
posture

120
00:09:19.400 --> 00:09:25.200
anterior tilt or the opposite foot rolls out the tibia rolls out the hip rolls

121
00:09:25.200 --> 00:09:32.280
out the pelvis rotates backward that those kind of classic patterns is how

122
00:09:32.280 --> 00:09:36.040
you can look at how what might be happening at the hip influences the

123
00:09:36.040 --> 00:09:39.510
foot and vice versa so if you have a hard time seeing what might be happening

124
00:09:39.510 --> 00:09:39.600
at

125
00:09:39.600 --> 00:09:43.880
one area you can work through these chains and figure out how the other

126
00:09:43.880 --> 00:09:50.600
areas are moving and what's likely happening but I love this animation for

127
00:09:50.600 --> 00:09:58.960
just kind of showing how the pelvis moves on the spine or on the sacrum so

128
00:09:58.960 --> 00:10:07.760
these are the SI joint movements here it's not quite to that scale but that's

129
00:10:07.760 --> 00:10:14.760
the micro movement where the pelvis is moving on these oblique axis what moves

130
00:10:14.760 --> 00:10:18.360
it the muscles but when we're looking at the pelvis it's more important to

131
00:10:18.360 --> 00:10:18.680
think

132
00:10:18.680 --> 00:10:25.400
of it in these facial lines and relationships because these are this is

133
00:10:25.400 --> 00:10:32.080
more of an engine type movement and in order to create enough force you're

134
00:10:32.080 --> 00:10:32.160
gonna

135
00:10:32.160 --> 00:10:37.640
have to link these muscles together so you got your obliques you got your your

136
00:10:37.640 --> 00:10:43.400
glutes your lats you'll notice that the quads are not featured in either the

137
00:10:43.400 --> 00:10:48.320
spiral line over here on the left or the functional line here on the right

138
00:10:48.320 --> 00:10:52.770
because they don't do a really good job of rotating the core they do more

139
00:10:52.770 --> 00:10:53.480
either

140
00:10:53.480 --> 00:11:02.080
vertical movement or chop type movement so here are those classic slings for

141
00:11:02.080 --> 00:11:06.920
rotating the body we use them in any throwing and striking sport for creating

142
00:11:06.920 --> 00:11:12.930
force at one or both arms and I like this picture a little bit better because

143
00:11:12.930 --> 00:11:13.040
it

144
00:11:13.040 --> 00:11:18.800
shows the fan of the fibers rather than in this picture it shows that it's just

145
00:11:18.800 --> 00:11:25.840
kind of a line which isn't isn't very accurate this picture shows the vertical

146
00:11:25.840 --> 00:11:31.560
relationship of the quad so when you see golfers getting into their knees they

147
00:11:31.560 --> 00:11:31.640
're

148
00:11:31.640 --> 00:11:39.200
avoiding their hips they're using more of this vertical movement as opposed to

149
00:11:39.200 --> 00:11:44.640
what we want for the golf swing being a little bit more rotational first and

150
00:11:44.640 --> 00:11:50.600
then using the quads kind of later when we do want to go vertical okay what are

151
00:11:50.600 --> 00:11:58.360
the pelvis goals in the golf swing we want to rotate the hips to and in order

152
00:11:58.360 --> 00:12:05.440
to load the glute muscles especially the trail glute muscles and then the lead

153
00:12:05.440 --> 00:12:11.920
side adductor will get loaded a little bit as well that helps create the engine

154
00:12:11.920 --> 00:12:12.120
as

155
00:12:12.120 --> 00:12:19.520
well as geometrically creating depth the the hips are big source of energy both

156
00:12:19.520 --> 00:12:25.080
pushing against the floor and then taking the reaction force from the ground

157
00:12:25.080 --> 00:12:25.400
and

158
00:12:25.400 --> 00:12:30.760
transferring that all the way up the chain into the ribcage and into the arms

159
00:12:30.760 --> 00:12:36.770
because we play on a tilted angle the hips are great at angling our body down

160
00:12:36.770 --> 00:12:37.160
to

161
00:12:37.160 --> 00:12:46.480
the golf ball it's primarily a glute motion and so it also the the glutes the

162
00:12:46.480 --> 00:12:52.720
the glute medius and the lateral hip muscles help with creating axis tilt so

163
00:12:52.720 --> 00:12:58.480
one of the big important factors for shallowing out the swing the pelvis helps

164
00:12:58.480 --> 00:13:03.520
position the upper body for both the precision of the low point as well as

165
00:13:03.520 --> 00:13:09.480
creating tilt in the flat spot and the the pelvis and the legs are helpful for

166
00:13:09.480 --> 00:13:14.920
shifting pressure which helps you create the moment arms against the the ground

167
00:13:14.920 --> 00:13:22.360
which allows you to create speed more easily okay let's dig into the key graphs

168
00:13:22.360 --> 00:13:28.760
for today's class starting with sway so here we have the pelvis sway graph the

169
00:13:28.760 --> 00:13:35.320
stock tour trains the stock tour swing trends for the sway graph are so the way

170
00:13:35.320 --> 00:13:41.760
that the system measures it will always be zero at address position address

171
00:13:41.760 --> 00:13:47.120
position is when the club starts to move it just takes them that sensor

172
00:13:47.120 --> 00:13:51.400
location or the digitized center the virtual sensor location and says that's

173
00:13:51.400 --> 00:13:56.600
where our pelvis is and then from there it's gonna map how it's moving so there

174
00:13:56.600 --> 00:14:02.400
is typically a minimal shift in the backswing plus or minus an inch and then

175
00:14:02.400 --> 00:14:08.840
there's about a three to six inch shift on the downswing and it will tend to

176
00:14:08.840 --> 00:14:14.800
stabilize around impact so you can see it's a little bit more of an aggressive

177
00:14:14.800 --> 00:14:18.360
movement there that would be around delivery position and then it

178
00:14:18.360 --> 00:14:25.360
stabilizes down during the release so the the key structures are looking at

179
00:14:25.360 --> 00:14:32.080
these lateral slings so the the glutes will provide some of this side to side

180
00:14:32.080 --> 00:14:38.400
stability a big part of it is the glute medius as well as the adductors if you

181
00:14:38.400 --> 00:14:42.840
tend to use more the quads or the front side of the body then you'll tend to

182
00:14:42.840 --> 00:14:48.200
have a little bit more lateral float especially swaying okay so Henrik Stenson

183
00:14:48.200 --> 00:14:54.240
we're going to take a look at his when when the line is negative or when so

184
00:14:54.240 --> 00:14:59.640
here's the sway graph so you got address top impact finish this is towards the

185
00:14:59.640 --> 00:15:04.200
target away from the target so when the line goes negative right here he's

186
00:15:04.200 --> 00:15:07.160
moving away from the target when it goes positive he's moving towards the

187
00:15:07.160 --> 00:15:07.440
target

188
00:15:07.440 --> 00:15:12.800
and you might look at this and think wow that's a lot of sloppy sliding towards

189
00:15:12.800 --> 00:15:17.360
the target but that's because of his pre move trigger let's take a quick look

190
00:15:17.360 --> 00:15:22.480
at that okay so we got Henrik and I put a line there where he's kind of at his

191
00:15:22.480 --> 00:15:27.040
setup position now before he takes the club back there he shifts all the way to

192
00:15:27.040 --> 00:15:32.080
there so this is what it was showing on that line or on the the graph that's

193
00:15:32.080 --> 00:15:37.560
zero so then during the backswing we saw about a four-inch shift so that gets

194
00:15:37.560 --> 00:15:42.200
him back to about where he should have been based on his initial setup position

195
00:15:42.200 --> 00:15:48.120
and then from there we see that 3 to 6 inch shift and then stabilizing down

196
00:15:48.120 --> 00:15:56.280
through impact so keep that in your mind so there's kind of his pre move or his

197
00:15:56.280 --> 00:16:00.800
pre move and then tiny little way shift once he gets to about here that's where

198
00:16:00.800 --> 00:16:05.480
he was in the normal position so if you just look at that to there that would

199
00:16:05.480 --> 00:16:09.520
look like the normal scale and a little bit of a plateau maybe a tiny bit of

200
00:16:09.520 --> 00:16:15.000
slide but not too bad it would look classic if he didn't have that first

201
00:16:15.000 --> 00:16:19.600
move okay so here we've got elk pretty good move so little pressure

202
00:16:19.600 --> 00:16:25.080
shift sometimes you'll see this little double peak in the backswing that's kind

203
00:16:25.080 --> 00:16:31.960
of like using more of like momentum to load the hips that's the way I think of

204
00:16:31.960 --> 00:16:36.760
it but you'll see a little bit more of that hip bump and then pretty good

205
00:16:36.760 --> 00:16:37.680
plateau

206
00:16:37.680 --> 00:16:44.800
or flat line through impact grant grant weight little more shift off the ball

207
00:16:44.800 --> 00:16:49.560
again this was partly when he was doing the stack and tilt stuff so he started

208
00:16:49.560 --> 00:16:55.600
a little bit more left he had a little bit more shift off the ball and then a

209
00:16:55.600 --> 00:17:00.620
little like you can see the hint of a plateau he was a little kind of slide

210
00:17:00.620 --> 00:17:05.180
slidey on the way through and more towards that high end you know almost seven

211
00:17:05.180 --> 00:17:12.540
inches of lateral movement during the downswing okay what happens with amateurs

212
00:17:12.540 --> 00:17:19.500
so when we're looking at the sway errors TPI's got you've got sway you've got

213
00:17:19.500 --> 00:17:25.900
slide you've got hangback and reverse pivot so sway would be when it's going

214
00:17:25.900 --> 00:17:32.360
down excessively slide would be when it's going up excessively on the way

215
00:17:32.360 --> 00:17:40.960
through hangback would be where it kind of goes like flat line or even away on

216
00:17:40.960 --> 00:17:46.440
the on the downswing so kind of going more negative and then reverse pivot is

217
00:17:46.440 --> 00:17:51.000
when it would go positive to negative you'll see that on some short game some

218
00:17:51.000 --> 00:17:56.520
wedge wedge shots but you'll see that also on bad golfers with their driver

219
00:17:56.520 --> 00:18:04.310
the swing relationships or the key ones for looking at the sway is the the

220
00:18:04.310 --> 00:18:04.440
white

221
00:18:04.440 --> 00:18:09.840
movement for looking at balancing the slide the timing of the trail arm

222
00:18:09.840 --> 00:18:17.000
straightening so again that can relate to either more of a hangback or a slide

223
00:18:17.000 --> 00:18:22.520
the club face position and then the classic you know steep arms versus

224
00:18:22.520 --> 00:18:32.760
shallow arms and body power okay so here we've got Colin this would be more of

225
00:18:32.760 --> 00:18:33.000
a

226
00:18:33.000 --> 00:18:39.520
hangback where we see not much of a shift there but then he only shifts this

227
00:18:39.520 --> 00:18:45.400
is an inch so he shifts half an inch and then starts going backward right away

228
00:18:45.400 --> 00:18:54.520
where is Colin okay so if we go to the setup position you can use the edge of

229
00:18:54.520 --> 00:19:01.960
the bag there as kind of your indicator so pretty stable there and then boom

230
00:19:01.960 --> 00:19:02.280
you

231
00:19:02.280 --> 00:19:06.640
can see it like right around here is where it starts to work back in that

232
00:19:06.640 --> 00:19:11.480
opposite direction so he basically plants over that spot it's an old baseball

233
00:19:11.480 --> 00:19:18.880
move and that's what it looks like graphically okay now we got run this is a

234
00:19:18.880 --> 00:19:23.720
big sway he doesn't get a lot of shift compared to where he started but

235
00:19:23.720 --> 00:19:28.480
compared to where he was at the top of swing he gets a fair amount of of down

236
00:19:28.480 --> 00:19:34.480
swing shift so keep that in the back of your mind so five inches of shift again

237
00:19:34.480 --> 00:19:39.720
you can use the edge of the divot or the golf cart in the background boom there

238
00:19:39.720 --> 00:19:40.680
's

239
00:19:40.680 --> 00:19:45.480
you can see on the graph it's kind of like a lady doesn't shift right off the

240
00:19:45.480 --> 00:19:52.760
ball it's that second half of the backswing so no sway and then he's swaying

241
00:19:52.760 --> 00:20:00.040
like crazy and then there's the shift from this way but it's not like he gets

242
00:20:00.040 --> 00:20:07.120
way past that foot so not too bad definitely I mean this way is pretty bad

243
00:20:07.120 --> 00:20:11.800
but the lateral movement after this way a little bit of plateau that part's not

244
00:20:11.800 --> 00:20:21.120
too bad okay here we've got Mike he's got sway and then kind of slide right no

245
00:20:21.120 --> 00:20:27.880
real no real lateral stability and if we compare we can see that he starts

246
00:20:27.880 --> 00:20:34.560
swaying earlier so there's the sway and then he kind of plateaus and then

247
00:20:34.560 --> 00:20:40.320
there's the slide so as you're looking through it there's not a lot of lateral

248
00:20:40.320 --> 00:20:45.680
glute stability he definitely uses more and load the knees fire the knees knees

249
00:20:45.680 --> 00:20:50.720
don't stop lateral movement very well so that's why he's got more of that sway

250
00:20:50.720 --> 00:20:55.760
slide pattern all right moving on to the pelvis lift so the stock towards wing

251
00:20:55.760 --> 00:21:01.120
what I tend to see on the 3d about a one inch drop in at the top of the swing

252
00:21:01.120 --> 00:21:01.280
or

253
00:21:01.280 --> 00:21:06.560
in the transition and then the pelvis will raise to a maximum height just after

254
00:21:06.560 --> 00:21:10.280
impact or around impact of about one inch higher than where it started so

255
00:21:10.280 --> 00:21:15.680
there's a little bit of kind of a squat and then a load as you straighten the

256
00:21:15.680 --> 00:21:23.840
legs and tuck the pelvis those both raise the pelvis sensor height so pelvis

257
00:21:23.840 --> 00:21:30.280
lift leg length can play a little bit of a roll that can relate to the sway as

258
00:21:30.280 --> 00:21:35.600
well I don't think I talked about there but the foot and knee motion will

259
00:21:35.600 --> 00:21:41.400
influence the pelvis height not just the posterior tilt and then the spine ax

260
00:21:41.400 --> 00:21:41.840
ial

261
00:21:41.840 --> 00:21:47.840
extension so if you start kind of in a in big S posture or C posture that can

262
00:21:47.840 --> 00:21:52.600
influence just by straightening the spine as you start moving that can

263
00:21:52.600 --> 00:22:03.730
influence the pelvis sensor oftentimes on the way through if it's not raising

264
00:22:03.730 --> 00:22:03.960
up

265
00:22:03.960 --> 00:22:07.680
then that's a sign that to me that it's more of an upper body dominant release

266
00:22:07.680 --> 00:22:13.400
and if it doesn't drop down that can be a little bit more of a associated like

267
00:22:13.400 --> 00:22:21.800
lift and chop versus if you see someone who's getting good lower body rotation

268
00:22:21.800 --> 00:22:26.120
they will tend to have or if they're getting good core loading they'll tend to

269
00:22:26.120 --> 00:22:34.160
be closer on this pattern Henrik pretty classic here so little squat a little

270
00:22:34.160 --> 00:22:43.560
load and then up on the way through let's see what that one looks like okay so

271
00:22:43.560 --> 00:22:48.040
there's kind of that one inch drop it basically just looks like it's saying

272
00:22:48.040 --> 00:22:52.880
level but remember the pelvis is turning on a bit of an angle so it's as it

273
00:22:52.880 --> 00:22:58.840
turns it moves kind of down the plane there's a there's that drop we saw where

274
00:22:58.840 --> 00:23:03.840
he loads into his legs and then there's that raising up and tilting the pelvis

275
00:23:03.840 --> 00:23:12.760
and then so right around there is that max height just after impact and then

276
00:23:12.760 --> 00:23:18.080
it's lowering as he comes back down from the verticals elk has a little bit

277
00:23:18.080 --> 00:23:18.280
more

278
00:23:18.280 --> 00:23:23.160
of that what I would call kind of upper body throw so it gives a little bit

279
00:23:23.160 --> 00:23:29.120
more kind of drop and buckle of the pelvis so he gets pretty big drop and

280
00:23:29.120 --> 00:23:38.840
then kind of stays there okay so doesn't help these wearing black pants so

281
00:23:38.840 --> 00:23:42.120
there's kind of that drop this is right around when we saw it really raising up

282
00:23:42.120 --> 00:23:46.040
with Henrik and you can see that all through there that belt buckle kind of

283
00:23:46.040 --> 00:23:51.360
stays the same height and you'll see a little bit more pronounced right arm

284
00:23:51.360 --> 00:23:57.680
straightening and even some shoulder blade give not too bad but a lot more

285
00:23:57.680 --> 00:24:07.400
kind of punch from that right arm early which is kind of ignoring using that

286
00:24:07.400 --> 00:24:13.280
rotational sling the abs don't look like they're too involved there okay and

287
00:24:13.280 --> 00:24:13.440
then

288
00:24:13.440 --> 00:24:18.560
grant weight little drop little lift that's pretty classic grant has some

289
00:24:18.560 --> 00:24:26.960
really good lower body action so right around right around there is where you

290
00:24:26.960 --> 00:24:31.480
start to see the lift there he reaches kind of his max and then comes on down

291
00:24:31.480 --> 00:24:37.560
it's got really like I said really good dynamic leg action TPI errors that they

292
00:24:37.560 --> 00:24:42.240
talk about are the hip launch loss of posture loss of posture being when

293
00:24:42.240 --> 00:24:46.200
basically the golfer stands up so instead of going down they'll have more of a

294
00:24:46.200 --> 00:24:51.160
flat line or even up and then the hip launch is when you see like a really big

295
00:24:51.160 --> 00:24:56.560
you know two or three inch movement typically that would come from somebody

296
00:24:56.560 --> 00:25:04.360
who's really early extending and you'll see them kind of pushing vertically

297
00:25:04.360 --> 00:25:08.320
against the ground typically have more of kind of that fast overtaking rate

298
00:25:08.320 --> 00:25:15.280
down at the bottom so with the swing relationships body versus arm in the

299
00:25:15.280 --> 00:25:19.960
release we even saw that a little bit in elk the wipe versus the cast the wipe

300
00:25:19.960 --> 00:25:26.680
and the lift are basically connected through that oblique movement where if

301
00:25:26.680 --> 00:25:30.600
you don't have the wipe if you have more of that arm throw you'll typically

302
00:25:30.600 --> 00:25:30.760
have

303
00:25:30.760 --> 00:25:38.040
more of a slide buckle and then the chop versus the the chop will typically not

304
00:25:38.040 --> 00:25:44.600
have like that transition drop it'll have a little bit more of just a straight

305
00:25:44.600 --> 00:25:51.980
flat or kind of straight ascension on the line as they start pulling down all

306
00:25:51.980 --> 00:25:52.200
right

307
00:25:52.200 --> 00:25:59.400
so we got Mike here pretty huge drop in the backswing and then gets back close

308
00:25:59.400 --> 00:26:04.330
to where he started and continues going up remember those guys were hitting

309
00:26:04.330 --> 00:26:04.520
their

310
00:26:04.520 --> 00:26:09.880
peak if we quickly flash through them they're hitting their peak height right

311
00:26:09.880 --> 00:26:14.480
around impact right around impact right around impact we're see reaching his

312
00:26:14.480 --> 00:26:20.200
peak height way after impact so let's see what that looks like that's probably

313
00:26:20.200 --> 00:26:26.960
close to where he's reaching his peak so there's the giant drop you know this

314
00:26:26.960 --> 00:26:27.120
is

315
00:26:27.120 --> 00:26:32.920
starting right around the height there

316
00:26:32.920 --> 00:26:39.200
dropping down and then through impact coming up coming up coming up coming up

317
00:26:39.200 --> 00:26:44.800
coming up coming up right around there is kind of his peak so this would

318
00:26:44.800 --> 00:26:45.000
probably

319
00:26:45.000 --> 00:26:50.920
fit more into that launch category okay now we got run with the loss of posture

320
00:26:50.920 --> 00:26:55.840
so little drop there and takeaway that's mostly happening from his knees it's

321
00:26:55.840 --> 00:27:01.390
not like a glute load or anything and then gets up a little taller and then

322
00:27:01.390 --> 00:27:02.240
goes

323
00:27:02.240 --> 00:27:07.880
up from there okay so right there's the drop as he's bringing the club back you

324
00:27:07.880 --> 00:27:12.440
can see that's happening all from the knees not from tilting and then there's

325
00:27:12.440 --> 00:27:19.440
the loss of posture lift and just kind of goes up a bit from there you know

326
00:27:19.440 --> 00:27:25.200
right there there's no real kind of down movement it's just more of a spin type

327
00:27:25.200 --> 00:27:30.160
movement and you can see kind of some of the evidence of that kind of overly

328
00:27:30.160 --> 00:27:36.440
rotated spin move not a lot of verticals going on in Ron's movement all right

329
00:27:36.440 --> 00:27:42.240
and we got a fun ride here from Colin so he goes down now you'll look at the

330
00:27:42.240 --> 00:27:47.720
scale and it's it's not like the five inch move that we saw with Mike but goes

331
00:27:47.720 --> 00:27:53.960
down goes down even more and then comes up really late let's see what that

332
00:27:53.960 --> 00:27:54.200
looks

333
00:27:54.200 --> 00:28:08.760
like so down down even more spin and then there it comes up all right last

334
00:28:08.760 --> 00:28:14.080
one we got the pelvis thrust so this is kind of the early extension graph and

335
00:28:14.080 --> 00:28:20.920
you will tend to see a little bit of thrust just because of where the sensor

336
00:28:21.160 --> 00:28:26.080
okay the last one we got is the pelvis thrust so the stock tour swing pattern

337
00:28:26.080 --> 00:28:31.120
has this kind of little curve there so you got about one inch thrust in the

338
00:28:31.120 --> 00:28:35.560
backswing moves to about zero in transition and then about a one inch

339
00:28:35.560 --> 00:28:43.680
thrust there at impact now part of that is the pelvis being wider than it is

340
00:28:43.680 --> 00:28:51.400
depth-wise so if you take the middle and you rotate around the hip okay and

341
00:28:51.400 --> 00:28:51.440
this

342
00:28:51.440 --> 00:28:54.360
does relate to some of the others but I want you to think about it so here's

343
00:28:54.360 --> 00:28:58.600
the pelvis it's a little bit wider than it is this way and the hips are out

344
00:28:58.600 --> 00:28:58.880
here

345
00:28:58.880 --> 00:29:04.560
if I rotate around this hip here not in the dead center if I rotate in the dead

346
00:29:04.560 --> 00:29:10.160
center then this thing doesn't move either that way or that way but if I

347
00:29:10.160 --> 00:29:16.170
rotate on the edge here you can see if I rotate this way there is a bit of

348
00:29:16.170 --> 00:29:16.520
thrust

349
00:29:16.520 --> 00:29:20.400
in both directions so if I rotate there and then I shift my weight and then I

350
00:29:20.400 --> 00:29:26.320
rotate there that's going to influence the movement

351
00:29:26.320 --> 00:29:31.250
somewhat like is that if this was one of ones it was really hard to look at

352
00:29:31.250 --> 00:29:32.080
when

353
00:29:32.080 --> 00:29:38.200
we weren't digitizing so key structures all the lower body the

354
00:29:38.200 --> 00:29:45.120
lumbar spine the the T spine starting to if it goes into extension or if it

355
00:29:45.120 --> 00:29:50.800
really goes into flexion that can influence what's going on here at the

356
00:29:50.800 --> 00:29:56.200
pelvis so are they using the abs versus the back quads versus the hip that's

357
00:29:56.200 --> 00:29:56.520
huge

358
00:29:56.520 --> 00:30:02.000
in the early extension discussion and then looking at the rotational slings you

359
00:30:02.000 --> 00:30:07.480
know the anterior sling versus the posterior slings okay the TPI errors are

360
00:30:07.480 --> 00:30:14.760
early extension which is kind of going way up there in the downswing or loss of

361
00:30:14.760 --> 00:30:18.120
posture if it's happening in the backswing so it just basically early extension

362
00:30:18.120 --> 00:30:18.360
or

363
00:30:18.360 --> 00:30:22.440
pelvis thrust gray errors are typically if they're too high you'll rarely see

364
00:30:22.440 --> 00:30:30.000
someone go too far away from the golf ball the swing relationships because

365
00:30:30.000 --> 00:30:34.240
early extension is one of the biggest shallowers this is looking at arm steep

366
00:30:34.240 --> 00:30:40.720
versus shallow early extension is one of the big helps for closing the face so

367
00:30:40.720 --> 00:30:45.680
face open versus face closed and then early extension is using more vertical

368
00:30:45.680 --> 00:30:53.640
force using more lower back mid back to create speed or lats to pull down so

369
00:30:53.640 --> 00:30:58.440
chopped versus body rotation okay so when the line goes up they're moving

370
00:30:58.440 --> 00:31:02.560
towards the golf ball when the line goes down they're moving away from it so

371
00:31:02.560 --> 00:31:09.840
henryx got a little bit of kind of early extension or loss of posture but if

372
00:31:09.840 --> 00:31:10.000
you

373
00:31:10.000 --> 00:31:14.640
look at the scale it's not too much so part of what makes it look this way is

374
00:31:14.640 --> 00:31:20.160
because he doesn't get shifted towards the the golf ball too much even in the

375
00:31:20.160 --> 00:31:25.000
follow-through but he definitely has a little bit of this backward movement all

376
00:31:25.000 --> 00:31:29.640
the way through the downswing that helps as tiger has described create space

377
00:31:29.640 --> 00:31:33.080
where you can kind of do anything where when you get into that early extension

378
00:31:33.080 --> 00:31:41.560
pattern you start getting stuck okay elkington classic pattern will shift away

379
00:31:41.560 --> 00:31:48.840
from it and then back up and through again 3.8 pretty small there

380
00:31:48.840 --> 00:31:55.800
grant weight little shift we'll shift back we'll shift on the way through so

381
00:31:55.800 --> 00:32:03.080
that's basically the representation of this camera moves a little bit but that

382
00:32:03.080 --> 00:32:08.600
look right there has that just tiny little s-curve and then it comes just off

383
00:32:08.600 --> 00:32:19.080
on the way through that's pretty pretty normal if we look at elk so again his

384
00:32:19.080 --> 00:32:27.750
upper body moves away from the golf ball a good bit but lower body stays

385
00:32:27.750 --> 00:32:28.360
relatively

386
00:32:28.360 --> 00:32:33.240
good this one depends a lot on the camera angle where the 3D system it's a

387
00:32:33.240 --> 00:32:37.160
little easier to see okay so the the big problems loss of posture early

388
00:32:37.160 --> 00:32:37.520
extension

389
00:32:37.520 --> 00:32:41.840
just the line going up too much usually here you can look at are they loading

390
00:32:41.840 --> 00:32:41.960
the

391
00:32:41.960 --> 00:32:46.720
foot and the hip or are they loading the knee are they lifting the arms and

392
00:32:46.720 --> 00:32:51.840
finishing the rotation with the body or are they getting their arms way behind

393
00:32:51.840 --> 00:32:58.600
and so they need to shallow it out the timing of the arm straightening and the

394
00:32:58.600 --> 00:33:03.560
loss of posture have a big kind of relationship together and then again

395
00:33:03.560 --> 00:33:07.560
standing up is one of the fastest ways to close the club face so what's the

396
00:33:07.560 --> 00:33:12.520
club face look like Colin for all of his lower body dysfunction actually is

397
00:33:12.520 --> 00:33:20.240
pretty good here with the early extension pattern so if we pull him up we know

398
00:33:20.240 --> 00:33:24.280
that there's a loss of going up but you can just use the edge of that divot

399
00:33:24.280 --> 00:33:31.520
there and you'll see you know if we draw that line he's not too bad

400
00:33:31.520 --> 00:33:37.960
club faces wide open there it's got a lot of other stuff going on but early

401
00:33:37.960 --> 00:33:44.000
extension is not his main issue like Mullins he's the rare one so we even

402
00:33:44.000 --> 00:33:50.000
call this an error but you'll see him create more depth okay so if we look at

403
00:33:50.000 --> 00:33:57.280
that line right about here you can see how much that sits backward and then he

404
00:33:57.280 --> 00:34:01.200
stays backward a lot of people who would sit backward like there would just

405
00:34:01.200 --> 00:34:07.240
launch into the golf ball but he kind of stays backward stands up throws it

406
00:34:07.240 --> 00:34:16.320
through finishes up and so not a big early extension pattern if anything it's

407
00:34:16.320 --> 00:34:21.080
almost more of a sitting in the heels type movement to support his upper body

408
00:34:21.080 --> 00:34:25.400
dominant pattern this is more of what you'll see with loss of posture early

409
00:34:25.400 --> 00:34:31.560
extension whatever you want to call so he's about five inches closer to golf

410
00:34:31.560 --> 00:34:35.120
while a little less than that but three inches in the backswing and another

411
00:34:35.120 --> 00:34:38.320
couple inches in the downswing and then another couple inches in the follow

412
00:34:38.320 --> 00:34:44.330
through okay so we can see again there's a little divot there you can use as

413
00:34:44.330 --> 00:34:44.680
your

414
00:34:44.680 --> 00:34:55.520
reference and the camera angle is going to have a big influence I'm shooting a

415
00:34:55.520 --> 00:35:01.080
little bit this way so it doesn't catch the backswing early extension quite as

416
00:35:01.080 --> 00:35:08.700
much and we have to look at okay that's the frame right there where the club

417
00:35:08.700 --> 00:35:15.320
moves so from there you can see that first movement goes backward then it

418
00:35:15.320 --> 00:35:19.920
starts to come forward a bit goes way forward there during the downswing and

419
00:35:19.920 --> 00:35:27.080
then more forward as he rotates kind of around the front of the foot instead of

420
00:35:27.080 --> 00:35:32.520
the heel so there because of so much rotation that's gonna finish even more

421
00:35:32.520 --> 00:35:39.720
forward so that's what that one looks like so I do think this is one of the

422
00:35:39.720 --> 00:35:44.920
ones where you can quickly see a pro-versing amateur so we've got if you look

423
00:35:44.920 --> 00:35:49.960
at this cluster you've got the three graphs there they look pretty similar

424
00:35:49.960 --> 00:35:55.520
pretty clean if I just pop up the three amateurs and there's a whole lot more

425
00:35:55.520 --> 00:36:01.960
noise going on right all these spaghetti lines aren't around zero you'll

426
00:36:01.960 --> 00:36:02.440
typically

427
00:36:02.440 --> 00:36:07.560
see much bigger movements with these amateurs then you will go back to here

428
00:36:07.560 --> 00:36:12.160
everything's pretty tight not a whole lot of change in the backswing one way

429
00:36:12.160 --> 00:36:17.360
or the other except for Henrik but we already know that that is only because

430
00:36:17.360 --> 00:36:24.080
like the only reason that's not there is because of that trigger move so these

431
00:36:24.080 --> 00:36:29.000
linear movements you will tend to see much more exaggerated differences between

432
00:36:29.000 --> 00:36:34.280
your pros and your amateurs so if you have the access to all the data take a

433
00:36:34.280 --> 00:36:40.600
quick look at the angles but then really dig into the linear that can give you

434
00:36:40.600 --> 00:36:40.600
a

435
00:36:40.600 --> 00:36:45.560
big indicator as to what slings they might be using and how their brain is

436
00:36:45.560 --> 00:36:51.320
organizing the movement so as always if you have any questions about this let

437
00:36:51.320 --> 00:36:51.320
us

438
00:36:51.320 --> 00:36:57.320
know comment below and we will help clarify it so closing in on the rest of

439
00:36:57.320 --> 00:37:02.360
the body graphs in the next one we will be looking at the thorax position

440
00:37:02.360 --> 00:37:04.640
graphs
