Kinematic Sequence

WEBVTT

1
00:00:00.000 --> 00:00:04.880
All right, coaches. Here we go again. So in this program, we're going to go

2
00:00:04.880 --> 00:00:06.960
through the common 3D

3
00:00:06.960 --> 00:00:12.530
graphs. We're going to talk about starting with the kinematic sequence. We're

4
00:00:12.530 --> 00:00:14.160
going to talk about

5
00:00:14.160 --> 00:00:19.360
kind of what's in a graph. So the common patterns that you'll see both of

6
00:00:19.360 --> 00:00:24.720
tour swings, as well as amateurs, as well as just the general guidelines

7
00:00:24.720 --> 00:00:25.840
suggested from

8
00:00:25.840 --> 00:00:30.950
TPIMM. But then I'm going to add my spin. We're going to talk about the related

9
00:00:30.950 --> 00:00:32.080
anatomy and the

10
00:00:32.080 --> 00:00:37.410
movement concepts that relate to that graph. So that you're not just kind of

11
00:00:37.410 --> 00:00:38.720
looking at the graph

12
00:00:38.720 --> 00:00:43.170
and coaching the graph, you're understanding the graph as it relates to the gol

13
00:00:43.170 --> 00:00:44.000
fer and the golf

14
00:00:44.000 --> 00:00:49.680
swing, so that you'll have a better chance of processing how to use that graph

15
00:00:49.680 --> 00:00:52.640
with your students

16
00:00:52.640 --> 00:00:57.880
instead of just getting fixated on making it look a certain way. So let's jump

17
00:00:57.880 --> 00:00:59.360
into the first graph

18
00:00:59.360 --> 00:01:03.360
in the series, which is the kinematic sequence. Okay, so here's the first graph

19
00:01:03.360 --> 00:01:04.240
, we've got the

20
00:01:04.240 --> 00:01:09.280
kinematic sequence, and this is great weight. So when we're looking at the k

21
00:01:09.280 --> 00:01:10.720
inematic sequence,

22
00:01:10.720 --> 00:01:18.790
this is a timeline of a golf swing. So we've got address, top of the swing,

23
00:01:18.790 --> 00:01:19.920
impact, finish.

24
00:01:20.640 --> 00:01:24.960
So that's these vertical black lines. And then scale is usually looking at

25
00:01:24.960 --> 00:01:27.280
degrees per second,

26
00:01:27.280 --> 00:01:33.190
but it's looking at rotational speeds. We'll talk about what the different

27
00:01:33.190 --> 00:01:34.080
colors look like on

28
00:01:34.080 --> 00:01:38.300
the next slide, or what the different colors represent on the next slide. But

29
00:01:38.300 --> 00:01:39.200
basically when

30
00:01:39.200 --> 00:01:42.760
it's rotating away from the target, it'll go negative when it's rotating

31
00:01:42.760 --> 00:01:43.920
towards the target,

32
00:01:43.920 --> 00:01:49.520
it will go positive. So when a line goes from negative to positive, that's when

33
00:01:49.520 --> 00:01:50.400
it's changing

34
00:01:50.400 --> 00:01:55.680
direction. So this is going to be our transition sequence here at the top. This

35
00:01:55.680 --> 00:01:56.080
is going to be our

36
00:01:56.080 --> 00:02:00.950
downswing sequence. We got impact right there. This gives you the kinematic

37
00:02:00.950 --> 00:02:02.400
sequence gives you a

38
00:02:02.400 --> 00:02:07.970
overall look at kind of the athleticism or or how the golfer is using their

39
00:02:07.970 --> 00:02:09.200
body to swing the golf

40
00:02:09.200 --> 00:02:17.800
club. So the different curves on the AMM graph are the pelvis rotation velocity

41
00:02:17.800 --> 00:02:19.920
, which is in AMM,

42
00:02:19.920 --> 00:02:24.430
it's in the plane of the pelvis. So you have to look at if you're looking at a

43
00:02:24.430 --> 00:02:25.680
different system,

44
00:02:25.680 --> 00:02:29.560
see if they're measuring it off of a vertical axis or in the plane, the pelvis,

45
00:02:29.560 --> 00:02:29.840
that would

46
00:02:29.840 --> 00:02:34.440
definitely affect the speeds, possibly the timings. Then we've got thoracic

47
00:02:34.440 --> 00:02:36.880
rotation. This is also,

48
00:02:36.880 --> 00:02:43.500
this is in the plane of the thorax. So it's own axis, similar to the pelvis.

49
00:02:43.500 --> 00:02:44.960
The lead upper arm

50
00:02:44.960 --> 00:02:49.280
in the club are measured in the swing plane. So the lead upper arm is looking

51
00:02:49.280 --> 00:02:50.640
at the left segment

52
00:02:50.640 --> 00:02:56.670
or the left upper arm. So there's a sensor right here. That's how they define

53
00:02:56.670 --> 00:02:57.520
the difference

54
00:02:57.520 --> 00:03:03.180
between the thorax sensor or this point digitized and the tricep sensor. So you

55
00:03:03.180 --> 00:03:04.640
have to look at some

56
00:03:04.640 --> 00:03:10.360
systems will look at the forearm segment. If they that's where they have their

57
00:03:10.360 --> 00:03:10.960
sensor

58
00:03:11.760 --> 00:03:14.220
on the back of the wrist. So you have to be careful to look at what they're

59
00:03:14.220 --> 00:03:14.800
measuring. The

60
00:03:14.800 --> 00:03:22.200
TPI, the AMM kinematic sequence is measuring the upper arm segment. And then

61
00:03:22.200 --> 00:03:23.120
the club segment

62
00:03:23.120 --> 00:03:29.680
is could be the grip. If depending on the sensor location, it could be the back

63
00:03:29.680 --> 00:03:30.160
of the hand

64
00:03:30.160 --> 00:03:36.850
or it could be the club head. With the AMM, it's measured from the sensor just

65
00:03:36.850 --> 00:03:37.680
below the grip.

66
00:03:39.680 --> 00:03:43.600
So basically from right here, it has a virtual sensor where the club head is,

67
00:03:43.600 --> 00:03:47.680
but the sensor that it's referencing is this one here. So it doesn't take into

68
00:03:47.680 --> 00:03:54.580
shaft flex, which could affect some of the numbers as well as possibly a little

69
00:03:54.580 --> 00:03:55.280
bit of the timing.

70
00:03:55.280 --> 00:04:00.850
Okay, so whenever we look at any one of these graphs, the first thing we're

71
00:04:00.850 --> 00:04:01.440
going to do is we're

72
00:04:01.440 --> 00:04:06.230
just going to go through looking at a few of the graphs and then look for just

73
00:04:06.230 --> 00:04:07.200
the overall shape

74
00:04:07.200 --> 00:04:11.440
and overall pattern. So here we've got kinematic sequence of grant weight.

75
00:04:11.440 --> 00:04:16.800
We're going to look at Henrik Stenson. I'm not exactly sure who collected this

76
00:04:16.800 --> 00:04:17.360
data.

77
00:04:17.360 --> 00:04:21.840
It's a little noisy, but I thought it'd be a good kind of representation of a

78
00:04:21.840 --> 00:04:22.400
different looking

79
00:04:22.400 --> 00:04:28.320
golf swing. And then we've got Steve Alkington. So in all of these 3D graphs,

80
00:04:28.320 --> 00:04:29.200
we're going to be

81
00:04:29.200 --> 00:04:33.140
going through in this program. We're going to look at these three golfers. You

82
00:04:33.140 --> 00:04:33.520
're going to get

83
00:04:33.520 --> 00:04:39.840
to know their swings as well as their graphs. If you put them all up, you'll

84
00:04:39.840 --> 00:04:41.440
see more similarities

85
00:04:41.440 --> 00:04:47.840
than differences. You'll see kind of like the transition where everything looks

86
00:04:47.840 --> 00:04:48.640
like it's coming

87
00:04:48.640 --> 00:04:54.370
out of a tube or at about the same slope. You'll see red crossing the axis

88
00:04:54.370 --> 00:04:56.080
first. You'll see

89
00:04:56.080 --> 00:05:00.490
the brown line kind of accelerating all the way to impact. A little less so

90
00:05:00.490 --> 00:05:01.520
here with Henrik.

91
00:05:02.320 --> 00:05:07.750
And you'll see kind of some organization to these peaks. And we'll talk a

92
00:05:07.750 --> 00:05:08.640
little bit more about

93
00:05:08.640 --> 00:05:15.900
one of the key pieces of the kinematic sequence right here, which is the arm to

94
00:05:15.900 --> 00:05:17.440
thorax position

95
00:05:17.440 --> 00:05:23.010
down at impact. Okay, so here are some quick guidelines with all of these 3D

96
00:05:23.010 --> 00:05:23.520
graphs that we're

97
00:05:23.520 --> 00:05:30.640
going to look at. First, 3D graphs don't necessarily give the answers. The 3D

98
00:05:30.640 --> 00:05:31.760
graphs

99
00:05:31.760 --> 00:05:35.690
gives you an area to focus your attention when analyzing the movement. The

100
00:05:35.690 --> 00:05:37.360
classic example is

101
00:05:37.360 --> 00:05:44.370
3D graph is like looking in an MRI. Well, an MRI may show a disc bulge, but

102
00:05:44.370 --> 00:05:45.040
that doesn't mean

103
00:05:45.040 --> 00:05:48.690
the disc bulge is causing the pain. All right, it just means that there's a

104
00:05:48.690 --> 00:05:49.840
disc bulge there.

105
00:05:49.840 --> 00:05:55.760
So it gives you an area to focus. It gives you some ways to look at the

106
00:05:55.760 --> 00:05:56.640
movement,

107
00:05:56.640 --> 00:05:59.820
but it doesn't give you a specific answer just because a graph looks a certain

108
00:05:59.820 --> 00:06:01.040
way. Also,

109
00:06:01.040 --> 00:06:04.480
never look at only one graph. You want to look at the movement system as a

110
00:06:04.480 --> 00:06:05.680
whole to see how the

111
00:06:05.680 --> 00:06:14.220
graphs relate to each other. That's a way to avoid chasing graphs. I can't

112
00:06:14.220 --> 00:06:15.600
stress enough.

113
00:06:15.600 --> 00:06:19.920
The goal is not to make every graph look perfect. The goal is to use the graphs

114
00:06:19.920 --> 00:06:21.360
to help influence

115
00:06:21.360 --> 00:06:25.680
their low point control, their clubface control, or their ability to create

116
00:06:25.680 --> 00:06:27.360
speed so that you can

117
00:06:27.360 --> 00:06:34.040
improve quality of strike as well as their consistency level. Also, think in

118
00:06:34.040 --> 00:06:35.120
movement,

119
00:06:35.120 --> 00:06:40.400
not just individual segments. Remember the rules from the position classes we

120
00:06:40.400 --> 00:06:40.640
did

121
00:06:40.640 --> 00:06:47.430
in this level too. There are some that are much more relevant for 3D,

122
00:06:47.430 --> 00:06:49.360
specifically looking at

123
00:06:50.080 --> 00:06:57.110
the relationship between certain segments, looking at the swing phases and what

124
00:06:57.110 --> 00:06:58.160
's going on,

125
00:06:58.160 --> 00:07:06.640
as well as the rest of them. In the position classes, we went into more details

126
00:07:06.640 --> 00:07:07.680
about some of these

127
00:07:07.680 --> 00:07:14.560
in the video. We're going to focus more on the look of the graph. So, these

128
00:07:14.560 --> 00:07:16.480
thinking about slings

129
00:07:16.480 --> 00:07:20.360
and relationships is going to be much more important when we're looking at

130
00:07:20.360 --> 00:07:20.800
graphs.

131
00:07:20.800 --> 00:07:25.440
Okay, specifically when we're looking at the kinematic sequence, kinematic

132
00:07:25.440 --> 00:07:26.400
sequences can be

133
00:07:26.400 --> 00:07:32.100
thought of as looking at the overall athleticism of the golfer. So, the overall

134
00:07:32.100 --> 00:07:33.440
athleticism of the

135
00:07:33.440 --> 00:07:41.000
swing. In kind of a quick and dirty way, our goal is to use our whole body to

136
00:07:41.000 --> 00:07:42.880
swing the club.

137
00:07:42.880 --> 00:07:47.660
Well, the kinematic sequence is looking at these major links. So, the major

138
00:07:47.660 --> 00:07:48.480
links would be the

139
00:07:48.480 --> 00:07:56.430
shoulder links the arm to the trunk. The hips link the legs to the trunk. The

140
00:07:56.430 --> 00:07:57.200
core links the

141
00:07:57.200 --> 00:08:01.180
two part of the trunk, so your rib cage and your pelvis, your wrist link, your

142
00:08:01.180 --> 00:08:02.080
arms to the club,

143
00:08:02.080 --> 00:08:09.060
and your feet link your legs to the ground. So, if we can use all of these

144
00:08:09.060 --> 00:08:10.160
areas well,

145
00:08:10.160 --> 00:08:14.080
then we'll typically have a really good kinematic sequence graph. When it comes

146
00:08:14.080 --> 00:08:15.200
to the spine or the

147
00:08:15.200 --> 00:08:21.150
core, we are looking at the abs, the lower back, the glutes a little bit, the l

148
00:08:21.150 --> 00:08:22.560
ats, the hip flexors.

149
00:08:22.560 --> 00:08:26.480
When we're looking at the shoulder link, we're really thinking of the shoulder

150
00:08:26.480 --> 00:08:26.880
girdle

151
00:08:26.880 --> 00:08:33.200
and the major muscles are the traps, the psoratus anterior, the lats, the pecs,

152
00:08:34.000 --> 00:08:40.030
the rotator cuff, including the bicep and the tricep. When we're thinking about

153
00:08:40.030 --> 00:08:40.880
the hips,

154
00:08:40.880 --> 00:08:45.920
we're looking at the glutes, the quads. Basically, if you looked at the leg,

155
00:08:45.920 --> 00:08:50.160
all the muscles on the front, so your hip flexors and quads, muscles on the

156
00:08:50.160 --> 00:08:50.480
back,

157
00:08:50.480 --> 00:08:54.360
you've got your glutes, your hamstrings, which I don't have on there, but the

158
00:08:54.360 --> 00:08:55.360
glutes and the

159
00:08:55.360 --> 00:08:59.510
hamstrings, and then the inside, you got your adductors and the outside, you

160
00:08:59.510 --> 00:09:00.480
got your abductors.

161
00:09:01.440 --> 00:09:05.680
But as I said, when we're thinking about the kinematic sequence, we're thinking

162
00:09:05.680 --> 00:09:06.160
most about

163
00:09:06.160 --> 00:09:10.470
these relationships. So with the relationships, we're going to look at the fasc

164
00:09:10.470 --> 00:09:11.040
ia slings.

165
00:09:11.040 --> 00:09:15.680
Over on the left, we have the spiral line. This is the front and the back view

166
00:09:15.680 --> 00:09:16.800
of the spiral line.

167
00:09:16.800 --> 00:09:25.200
This is one of the most important rotational slings. We can see the rhomboids

168
00:09:25.200 --> 00:09:25.920
connect to the

169
00:09:25.920 --> 00:09:32.320
serratus, connect around here to the obliques, which work their way down the

170
00:09:32.320 --> 00:09:32.880
leg, all the way

171
00:09:32.880 --> 00:09:36.960
down to the feet. So that right there, if you could imagine kind of winding and

172
00:09:36.960 --> 00:09:38.240
coiling that up,

173
00:09:38.240 --> 00:09:42.640
that's a great way to get the whole body to work in a rotational pattern. If we

174
00:09:42.640 --> 00:09:43.120
look at the

175
00:09:43.120 --> 00:09:48.160
functional slings, the lat and the glute, those fibers are running on an angle

176
00:09:48.160 --> 00:09:49.360
kind of like this,

177
00:09:49.360 --> 00:09:56.000
that direction fiber will create some rotation. If we look at the anterior

178
00:09:56.000 --> 00:09:56.800
functional sling,

179
00:09:56.800 --> 00:10:01.220
you'll see most of the fibers are running vertically. So this would be more of

180
00:10:01.220 --> 00:10:03.040
an up and down pattern

181
00:10:03.040 --> 00:10:06.310
where the backside of the body is going to create more rotation in the

182
00:10:06.310 --> 00:10:07.680
functional sling plane.

183
00:10:07.680 --> 00:10:15.390
So our goal is to use many of these rotation muscles as our primary drivers.

184
00:10:15.390 --> 00:10:16.880
Now, I don't love

185
00:10:16.880 --> 00:10:23.500
this artist's rendition because it's not quite as linear as that. It's more of

186
00:10:23.500 --> 00:10:25.040
a couple of fans.

187
00:10:25.040 --> 00:10:30.080
So this is a little better picture where you've got fibers going in different

188
00:10:30.080 --> 00:10:30.640
directions.

189
00:10:30.640 --> 00:10:40.880
But even this isn't quite as complete as I would like it to be. So you've got

190
00:10:40.880 --> 00:10:41.760
all these muscles

191
00:10:41.760 --> 00:10:45.720
kind of or you've got all these different fibers of your internal external ob

192
00:10:45.720 --> 00:10:46.880
lique kind of running

193
00:10:46.880 --> 00:10:53.040
down this way, coming and connecting with the serratus right through here,

194
00:10:53.040 --> 00:10:53.840
which connects with

195
00:10:53.840 --> 00:10:58.880
the rhomboids there. So I've got a link from that part of my spine wrapping

196
00:10:58.880 --> 00:11:00.240
around to there,

197
00:11:00.240 --> 00:11:04.610
which allows for this powerful trunk rotation. And then I've got the back

198
00:11:04.610 --> 00:11:06.640
muscles connecting

199
00:11:06.640 --> 00:11:12.350
to the opposite glute. So these two kind of rotate the spine this way. So if I

200
00:11:12.350 --> 00:11:13.760
'm rotating here with

201
00:11:13.760 --> 00:11:18.600
the back and here with the front, the combination can create some pretty

202
00:11:18.600 --> 00:11:20.880
explosive rotational speed.

203
00:11:20.880 --> 00:11:25.520
We see that casually in walking, but we see that in pretty much every throwing

204
00:11:25.520 --> 00:11:26.560
and striking sport.

205
00:11:26.560 --> 00:11:33.960
Now, when we're looking specifically to golf, you also want to look at kind of

206
00:11:33.960 --> 00:11:34.800
the deep muscles of

207
00:11:34.800 --> 00:11:38.930
the arm versus the superficial muscles of the arm. I've got this picture in

208
00:11:38.930 --> 00:11:40.400
here for one really

209
00:11:40.400 --> 00:11:46.000
key relationship. So down in the release, I talk a lot about kind of using the

210
00:11:46.000 --> 00:11:47.360
forearms properly.

211
00:11:47.360 --> 00:11:54.240
This shows the direct link between going into extension here and the shoulder

212
00:11:54.240 --> 00:11:55.040
going into more

213
00:11:55.040 --> 00:12:03.280
of a shrug pattern. So these two will tend to kind of coordinate together. So

214
00:12:03.280 --> 00:12:05.760
if you hear some people

215
00:12:05.760 --> 00:12:11.010
online, other instructors advocating more of an extension style release, if you

216
00:12:11.010 --> 00:12:12.720
understand the

217
00:12:12.720 --> 00:12:16.790
anatomy, then you know that they're also advocating a little bit more of a

218
00:12:16.790 --> 00:12:18.080
shrug of the shoulder.

219
00:12:18.080 --> 00:12:21.960
If they then say, no, I don't want the shoulder to shrug, you're now asking for

220
00:12:21.960 --> 00:12:22.720
conflicting

221
00:12:22.720 --> 00:12:26.360
movements or basically using part of a chain instead of the whole chain. And

222
00:12:26.360 --> 00:12:27.040
the body doesn't

223
00:12:27.040 --> 00:12:32.780
organize movement as well that way. So our goal is to use some of these smaller

224
00:12:32.780 --> 00:12:34.640
, deeper arm muscles

225
00:12:34.640 --> 00:12:38.900
so that we can use some of the bigger trunk muscles as the major engine. All

226
00:12:38.900 --> 00:12:40.000
right, so the

227
00:12:40.000 --> 00:12:45.200
kinematic sequence graph, our goals are to use the whole body to create speed.

228
00:12:45.200 --> 00:12:46.480
And by having a

229
00:12:46.480 --> 00:12:53.050
sequencing, you're actually allowing more time to apply the force. When you

230
00:12:53.050 --> 00:12:56.080
show you a little demo,

231
00:12:56.080 --> 00:13:01.180
I do to kind of help people feel this using the whole body to create speed. And

232
00:13:01.180 --> 00:13:04.080
then kinematics-wise,

233
00:13:04.080 --> 00:13:08.730
our goal is to, or what I will tend to see is golfers who have a better kinem

234
00:13:08.730 --> 00:13:09.520
atic sequence,

235
00:13:09.520 --> 00:13:16.550
tended to have a better 3D flat spot, somewhat. Basically, in order to use, in

236
00:13:16.550 --> 00:13:17.360
order to sequence

237
00:13:17.360 --> 00:13:20.600
and use the lower body first, you're going to tend to create a little bit of

238
00:13:20.600 --> 00:13:21.200
access tilt.

239
00:13:21.200 --> 00:13:25.440
To create that access tilt and not hit it fat, you're also then going to power

240
00:13:25.440 --> 00:13:27.120
the kind of

241
00:13:27.120 --> 00:13:31.740
mid-down swing more with the core muscles. We're going to get into a rotation

242
00:13:31.740 --> 00:13:32.800
side bend. So then

243
00:13:32.800 --> 00:13:37.150
if you were early with your arms, you would bottom out behind the ball. So that

244
00:13:37.150 --> 00:13:39.360
encourages the later

245
00:13:39.360 --> 00:13:45.020
arm release, and that later arm release helps produce this 3D flat spot. So the

246
00:13:45.020 --> 00:13:45.440
kinematic

247
00:13:45.440 --> 00:13:51.070
sequence is just a good rough look at how the person is creating speed. A quick

248
00:13:51.070 --> 00:13:52.480
little demo that

249
00:13:52.480 --> 00:13:58.750
I do with my students for kind of feeling the whole body create speed is if I

250
00:13:58.750 --> 00:13:59.840
had a band out

251
00:13:59.840 --> 00:14:03.910
in front kind of like this, and I will say I'm doing a lefty just because of

252
00:14:03.910 --> 00:14:04.960
where the band is,

253
00:14:06.000 --> 00:14:10.160
I would normally just put my hands in place, but I've got a band here to apply

254
00:14:10.160 --> 00:14:10.720
a little bit of

255
00:14:10.720 --> 00:14:16.630
resistance. My goal is when I go to turn this, I've got my abs on and I can

256
00:14:16.630 --> 00:14:17.920
feel this all the way

257
00:14:17.920 --> 00:14:24.000
down into my feet. I can feel basically my whole body working in tandem. What

258
00:14:24.000 --> 00:14:25.200
most people do when

259
00:14:25.200 --> 00:14:28.110
they first push into me is they do it more like this, and they're just using

260
00:14:28.110 --> 00:14:29.280
their shoulder girl

261
00:14:29.280 --> 00:14:33.910
and kind of locking their legs in place. So the speed is happening more from

262
00:14:33.910 --> 00:14:35.280
the shoulders versus

263
00:14:35.280 --> 00:14:40.150
here, having the speed happen more from the total body. So our goal with the k

264
00:14:40.150 --> 00:14:40.880
inematic

265
00:14:40.880 --> 00:14:45.150
sequence is getting our whole body to input the force through the hands onto

266
00:14:45.150 --> 00:14:45.920
the club.

267
00:14:45.920 --> 00:14:50.960
Okay, the stock tour swing trends in the kinematic sequence. So what are the

268
00:14:50.960 --> 00:14:51.920
common patterns that

269
00:14:51.920 --> 00:14:59.500
we'll see? So the key phase is to look at, you've got your transition, your

270
00:14:59.500 --> 00:15:00.880
peak, and then your

271
00:15:00.880 --> 00:15:05.120
acceleration, deceleration rates, and then this relationship here at impact. So

272
00:15:05.120 --> 00:15:06.400
transition sequence

273
00:15:06.400 --> 00:15:12.090
one, two, three, four is basically looking at pelvis, then trunk, then arm,

274
00:15:12.090 --> 00:15:13.920
then club. So this

275
00:15:13.920 --> 00:15:19.060
example here was the kind of the most apparent where you can see red line,

276
00:15:19.060 --> 00:15:20.800
green line, blue line,

277
00:15:20.800 --> 00:15:23.670
brown line going from negative to positive. Remember, when it goes from

278
00:15:23.670 --> 00:15:24.640
negative to positive,

279
00:15:24.640 --> 00:15:29.510
that's when it's changing directions. The peak sequence can change. You'll

280
00:15:29.510 --> 00:15:30.480
typically see the

281
00:15:30.480 --> 00:15:37.500
lower body first for most work offers. But then whether it's the trunk or the

282
00:15:37.500 --> 00:15:39.040
arm can depend a

283
00:15:39.040 --> 00:15:43.280
little bit. Some golfers who hit the ball a long way tend to be very stacked up

284
00:15:43.280 --> 00:15:44.640
instead of having

285
00:15:44.640 --> 00:15:50.210
a really clear progression of their peaks. But you will almost always see the

286
00:15:50.210 --> 00:15:51.360
lower body first

287
00:15:51.360 --> 00:15:57.980
and the club last. Now keep in mind the timing of these peaks. This peak right

288
00:15:57.980 --> 00:15:59.280
here, where the

289
00:15:59.280 --> 00:16:02.960
where the arm, the lead upper arm is reaching max speed is right around

290
00:16:02.960 --> 00:16:04.240
delivery position.

291
00:16:04.240 --> 00:16:10.560
So basically right around there is when the kinematic sequence, when everything

292
00:16:10.560 --> 00:16:11.120
is starting

293
00:16:11.120 --> 00:16:17.900
to decelerate because the club is getting accelerated. So the tran, the kinem

294
00:16:17.900 --> 00:16:19.520
atic sequence is really

295
00:16:19.520 --> 00:16:28.440
this impulse or this kind of early right there, right there. So that's when I

296
00:16:28.440 --> 00:16:30.240
want the whole body

297
00:16:30.240 --> 00:16:35.810
working. When I see some amateurs demonstrating when I talk to them, they try

298
00:16:35.810 --> 00:16:36.880
to get the the

299
00:16:36.880 --> 00:16:41.520
sequence happening for the whole downswing. Like they do it slow or very late.

300
00:16:41.520 --> 00:16:43.200
So just keep that

301
00:16:43.200 --> 00:16:49.990
in the back of your mind. Club acceleration, the club accelerating the impact

302
00:16:49.990 --> 00:16:51.760
is basically looking

303
00:16:51.760 --> 00:16:55.940
at how this brown line is peaking all the way to impact. I don't like to see a

304
00:16:55.940 --> 00:16:56.800
long plateau.

305
00:16:56.800 --> 00:17:01.100
Little plateau isn't the worst, but some amateurs will actually have it deceler

306
00:17:01.100 --> 00:17:02.320
ating or plateauing

307
00:17:02.320 --> 00:17:12.070
pretty hard. That usually is a sign of a little bit of either an early kind of

308
00:17:12.070 --> 00:17:12.720
early internal

309
00:17:12.720 --> 00:17:16.010
rotation of that trail arm or a little bit more of a scoop style release down

310
00:17:16.010 --> 00:17:16.720
at the bottom.

311
00:17:16.720 --> 00:17:21.760
Deceleration slopes. So looking at the lines kind of having more of a

312
00:17:21.760 --> 00:17:22.800
mountainous peak instead

313
00:17:22.800 --> 00:17:26.710
of a hill. So in this graph, you can see the blue line has a little bit more of

314
00:17:26.710 --> 00:17:27.760
a hill, more of a

315
00:17:27.760 --> 00:17:34.800
less sharp deceleration that could indicate a little release issue. But that

316
00:17:34.800 --> 00:17:36.000
you'll see it much

317
00:17:36.000 --> 00:17:41.570
worse when we look at the amateur golfers. And then the last piece there is a

318
00:17:41.570 --> 00:17:42.960
relationship that I've

319
00:17:42.960 --> 00:17:47.480
seen with most tour golfers, which is the chest moving faster than the arm

320
00:17:47.480 --> 00:17:48.800
impact. So with this

321
00:17:48.800 --> 00:17:54.370
golfer, you'll see that the green line is above the blue line. So basically

322
00:17:54.370 --> 00:17:56.720
that blue line is the arm

323
00:17:56.720 --> 00:18:02.480
kind of like almost reconnecting as the chest continues to turn. Instead of a

324
00:18:02.480 --> 00:18:03.280
lot of amateurs,

325
00:18:03.280 --> 00:18:08.850
you'll see that arm pulling more around the body. We'll look at that. Now keep

326
00:18:08.850 --> 00:18:10.400
in mind that these

327
00:18:10.400 --> 00:18:16.430
sensors are representing the movement. They aren't the movement. So when we

328
00:18:16.430 --> 00:18:18.000
look at the different

329
00:18:18.000 --> 00:18:22.720
graphs, keep in mind what each sensor is representing. The red line is the pel

330
00:18:22.720 --> 00:18:24.240
vis sensor. The pelvis

331
00:18:24.240 --> 00:18:33.160
sensor is like a summary of what's happening at the SI joint, the hip, the foot

332
00:18:33.160 --> 00:18:34.000
, the knee,

333
00:18:34.000 --> 00:18:38.880
the lumbar spine. So there are all these movements happening in that whole

334
00:18:38.880 --> 00:18:40.240
lower section that just

335
00:18:40.240 --> 00:18:44.180
gets summarized into this one graph. So you may look at this and this is why

336
00:18:44.180 --> 00:18:45.360
you have to be careful

337
00:18:45.360 --> 00:18:49.980
saying what the graph says, because you might look at the say, "Hey, your hips

338
00:18:49.980 --> 00:18:50.800
are slow."

339
00:18:50.800 --> 00:18:54.060
But maybe it's not the hips. Maybe it's more what's happening at the foot and

340
00:18:54.060 --> 00:18:54.400
ankle

341
00:18:54.400 --> 00:18:59.280
that's not being transferred up to the pelvis. So we'll look at the video of

342
00:18:59.280 --> 00:19:00.000
these golfers,

343
00:19:00.000 --> 00:19:07.030
which will help dial this in a little bit. The upper body sensor is looking at

344
00:19:07.030 --> 00:19:07.760
what's happening

345
00:19:07.760 --> 00:19:13.160
with the ribs and the thoracic spine, as well as the core. So abs and glutes

346
00:19:13.160 --> 00:19:14.320
versus the back

347
00:19:14.320 --> 00:19:19.000
and the hips or those rotational slings. Are they using more of a vertical

348
00:19:19.000 --> 00:19:20.320
movement or are they doing

349
00:19:20.320 --> 00:19:25.200
more rotation or are they doing more extension? There's a handful of options

350
00:19:25.200 --> 00:19:25.840
that they could be

351
00:19:25.840 --> 00:19:32.080
doing that would influence this green green line. The blue line, the arm sensor

352
00:19:32.080 --> 00:19:33.440
, is factoring in

353
00:19:33.440 --> 00:19:39.110
some of the rib movement, but mostly shoulder blade and shoulder. So I can

354
00:19:39.110 --> 00:19:41.680
speed it up just by

355
00:19:41.680 --> 00:19:46.720
moving the shoulder. I could speed it up just by moving shoulder blade or both.

356
00:19:46.720 --> 00:19:49.520
And it doesn't

357
00:19:49.520 --> 00:19:53.680
necessarily mean that that's where I don't have to use the shoulder muscles to

358
00:19:53.680 --> 00:19:54.720
accelerate it.

359
00:19:54.720 --> 00:20:00.160
I could be flinging it off more with the ribs and the shoulder blade movement,

360
00:20:00.160 --> 00:20:06.360
not just pulling with the arm. And then the last is the club sensor, which is

361
00:20:06.360 --> 00:20:07.280
largely influenced

362
00:20:07.280 --> 00:20:14.550
by the wrist forms or the arms and the hands. The key swing relationships,

363
00:20:14.550 --> 00:20:15.520
understanding steeps

364
00:20:15.520 --> 00:20:20.640
and shallows. Typically, a bad kinematic sequence means I'm either really steep

365
00:20:20.640 --> 00:20:23.360
or the club face is

366
00:20:23.360 --> 00:20:28.680
really open. And then I have to use more of this stall flip type movement down

367
00:20:28.680 --> 00:20:29.680
at the bottom,

368
00:20:29.680 --> 00:20:36.340
where I quickly shallow out and I quickly close the face. In general, you can

369
00:20:36.340 --> 00:20:37.520
summarize that the

370
00:20:37.520 --> 00:20:44.140
power sources, either more total body rotational speed, or you could get into

371
00:20:44.140 --> 00:20:45.920
is it more upper body

372
00:20:45.920 --> 00:20:51.280
dominant? Is it more vertical versus rotational? The kinematic sequence can

373
00:20:51.280 --> 00:20:52.480
kind of help guide you

374
00:20:52.480 --> 00:20:57.740
into which of the buckets that kind of put your golfers. The TPI errors that

375
00:20:57.740 --> 00:20:58.800
they typically look

376
00:20:58.800 --> 00:21:02.040
at are fanning of the curves, which we'll look at here on the next slide.

377
00:21:02.040 --> 00:21:04.160
Transition sequence.

378
00:21:05.440 --> 00:21:09.320
So we'll see that with some of the amateurs, where there's not a clear deline

379
00:21:09.320 --> 00:21:10.560
ation of lower body

380
00:21:10.560 --> 00:21:16.130
initiating transition. And then poor deceleration rates, kind of more flat

381
00:21:16.130 --> 00:21:19.280
lines right through here,

382
00:21:19.280 --> 00:21:24.410
as opposed to having these peaks. So if we look at fanning the curves, here's a

383
00:21:24.410 --> 00:21:25.680
zoomed in version

384
00:21:25.680 --> 00:21:30.400
of that kinematic sequence. First transition sequence, you can see red, green,

385
00:21:30.400 --> 00:21:31.280
blue, brown,

386
00:21:31.280 --> 00:21:35.590
there's a clear order to those. So that will have a really smooth look where

387
00:21:35.590 --> 00:21:36.720
the lower body

388
00:21:36.720 --> 00:21:41.760
is initiating first. And then the fanning the curves or the cast sequence,

389
00:21:41.760 --> 00:21:42.560
whenever you see

390
00:21:42.560 --> 00:21:48.800
the more distal segment above the proximal segment. So in this case, the red

391
00:21:48.800 --> 00:21:49.760
line is moving

392
00:21:49.760 --> 00:21:56.610
above the green line. That means that the hips are kind of outracing the upper

393
00:21:56.610 --> 00:21:57.280
body.

394
00:21:58.160 --> 00:22:03.760
So the hips are moving just slightly faster than the upper body. That creates a

395
00:22:03.760 --> 00:22:04.400
little bit of an

396
00:22:04.400 --> 00:22:09.280
eccentric stretch, which is associated with more of this pre-stretch or short

397
00:22:09.280 --> 00:22:10.560
stretch,

398
00:22:10.560 --> 00:22:14.800
shortened cycle that creates a little bit more power. So you'll commonly see

399
00:22:14.800 --> 00:22:16.000
that red to green,

400
00:22:16.000 --> 00:22:21.040
and you'll commonly see that arm to club. Those are both good signs of creating

401
00:22:21.040 --> 00:22:21.760
lag,

402
00:22:21.760 --> 00:22:26.810
where a fanning of the curves, which we'll see with the amateurs, it's going to

403
00:22:26.810 --> 00:22:27.360
be more,

404
00:22:27.360 --> 00:22:33.200
the red is always below, the brown is always above, you'll see what that means

405
00:22:33.200 --> 00:22:33.760
here in a bit.

406
00:22:33.760 --> 00:22:41.200
Okay, so now if we jump back in, here's a grant weight, here's Henrik Stenson,

407
00:22:41.200 --> 00:22:46.270
here's Steve Elkington, you can pause those and look at them a little bit more.

408
00:22:46.270 --> 00:22:47.280
But you'll see

409
00:22:47.920 --> 00:22:52.960
these common, common patterns. The main areas that we're going to look at now

410
00:22:52.960 --> 00:22:53.600
as we jump to the

411
00:22:53.600 --> 00:22:59.520
amateurs are the transition sequence, the peaking order, the deceleration rates

412
00:22:59.520 --> 00:23:00.560
, and we'll look at

413
00:23:00.560 --> 00:23:08.280
here, if I jump back up with grant weight, we can look through those transition

414
00:23:08.280 --> 00:23:09.120
sequence,

415
00:23:09.120 --> 00:23:14.270
good, peaking order, one, two, three, four, deceleration rates, pretty solid

416
00:23:14.270 --> 00:23:15.120
club accelerating

417
00:23:15.120 --> 00:23:21.680
rate to impact, and then there's the peak where the torso is above the arm.

418
00:23:21.680 --> 00:23:27.360
Little noisy data here with Henrik, which makes it harder to see some of these

419
00:23:27.360 --> 00:23:28.080
crossing points,

420
00:23:28.080 --> 00:23:34.700
but definitely one, probably two, three, four, and then more of the stacked

421
00:23:34.700 --> 00:23:36.080
peaks, that's not

422
00:23:36.080 --> 00:23:42.120
100% uncommon, and then pretty good deceleration rates, pretty good

423
00:23:42.120 --> 00:23:44.320
acceleration rate to impact,

424
00:23:44.320 --> 00:23:50.940
and blue line under green line crossing impact. Okay, close, but one, two,

425
00:23:50.940 --> 00:23:51.840
three, four,

426
00:23:51.840 --> 00:23:59.910
really good peaking order, we've got accelerating rate to impact, good deceler

427
00:23:59.910 --> 00:24:00.800
ation rates,

428
00:24:00.800 --> 00:24:07.000
and the blue line or the arm underneath the club line, or sorry, the torso line

429
00:24:07.000 --> 00:24:07.360
.

430
00:24:09.360 --> 00:24:17.600
Okay, now if we look at the amateurs, so amateurs, this is a little bit more

431
00:24:17.600 --> 00:24:22.320
classic what we'll see, this is pretty classic fanning the curves, he's still

432
00:24:22.320 --> 00:24:23.120
got the red line

433
00:24:23.120 --> 00:24:27.620
crossing there, so we've got lower body initiating transition, but then it's

434
00:24:27.620 --> 00:24:28.160
kind of

435
00:24:28.160 --> 00:24:33.880
toss up in those two, three, club is much later, but we can see that club, that

436
00:24:33.880 --> 00:24:35.200
brown line above

437
00:24:35.200 --> 00:24:40.320
the other lines, almost on a different slope for the entire downswing, that's

438
00:24:40.320 --> 00:24:41.760
classic cast pattern,

439
00:24:41.760 --> 00:24:46.480
we also see the red line underneath everything, so he's not empowering the

440
00:24:46.480 --> 00:24:47.840
swing, the peaking order

441
00:24:47.840 --> 00:24:52.640
is not being driven by the lower body, in fact if you look at his peaks, his

442
00:24:52.640 --> 00:24:53.760
peaks are reversed

443
00:24:53.760 --> 00:24:58.460
order, so while sometimes you'll see it stacked, you'll rarely see a tour pro

444
00:24:58.460 --> 00:24:59.520
where it's this

445
00:25:00.080 --> 00:25:06.960
elaborate or exaggerated, where the lower body is last, and then if you look at

446
00:25:06.960 --> 00:25:07.120
the

447
00:25:07.120 --> 00:25:13.760
arm to club, or sorry the arm to torso, this is going to look like that arm

448
00:25:13.760 --> 00:25:14.560
pulling across,

449
00:25:14.560 --> 00:25:20.130
that's why the arm still has so much speed compared to a little bit more of a

450
00:25:20.130 --> 00:25:21.440
kind of a good full

451
00:25:21.440 --> 00:25:31.360
release, where the arm is almost getting passed by the chest, but decent timing

452
00:25:31.360 --> 00:25:37.200
of the, or peaking in the release, we'll give him that piece, okay, now we've

453
00:25:37.200 --> 00:25:39.280
got second golfer

454
00:25:39.280 --> 00:25:45.680
here, transition sequence is a mess, arm might be changing direction first,

455
00:25:45.680 --> 00:25:47.440
this is the classic,

456
00:25:47.440 --> 00:25:54.160
you'll see that cast where the club line is above, so that's usually indicating

457
00:25:54.160 --> 00:25:55.920
some type of cast

458
00:25:55.920 --> 00:26:00.800
especially from the wrist, he's got decent body sequence there, it's just not

459
00:26:00.800 --> 00:26:02.720
leading the club,

460
00:26:02.720 --> 00:26:07.010
the club is leading the race, and then he has a little bit of a peaking or de

461
00:26:07.010 --> 00:26:08.160
celeration rates,

462
00:26:08.160 --> 00:26:13.680
so overall this isn't too bad, this is a mid single digit, something like that,

463
00:26:16.880 --> 00:26:25.540
okay lastly this is Ron, this is classic casting, so decent transition order,

464
00:26:25.540 --> 00:26:26.960
he's pretty consistent,

465
00:26:26.960 --> 00:26:32.100
but brown line is always above the blue, blue is always above the brown, brown

466
00:26:32.100 --> 00:26:33.280
is always above

467
00:26:33.280 --> 00:26:37.520
the red, that's the classic fanning of the curves, that just looks like there's

468
00:26:37.520 --> 00:26:37.680
no,

469
00:26:37.680 --> 00:26:44.710
there's no downswing stretch whatsoever, so he's not getting any, this doesn't

470
00:26:44.710 --> 00:26:45.360
beat this,

471
00:26:45.360 --> 00:26:49.570
this doesn't beat that, and that doesn't beat this, so the only way that can

472
00:26:49.570 --> 00:26:50.720
happen is if I'm

473
00:26:50.720 --> 00:26:57.340
kind of really gradually moving the outer segment faster than the inside, well

474
00:26:57.340 --> 00:26:58.480
if you remember,

475
00:26:58.480 --> 00:27:03.090
you know that would be typically using more of my big muscles first before I

476
00:27:03.090 --> 00:27:04.320
used my small muscles,

477
00:27:04.320 --> 00:27:11.840
so this guy will almost always complain about power, we also see that there's

478
00:27:11.840 --> 00:27:13.280
no real peaking,

479
00:27:13.280 --> 00:27:18.400
there's no decelerations, especially you can see this is going to be a release

480
00:27:18.400 --> 00:27:23.000
issue here where we see the club is decelerating coming into impact, that's a

481
00:27:23.000 --> 00:27:24.000
long plateau,

482
00:27:24.000 --> 00:27:28.860
don't like to see that, so that's more of kind of the classic amateur issues

483
00:27:28.860 --> 00:27:29.920
that we'll see,

484
00:27:29.920 --> 00:27:39.120
so here we have the three pros, again you can kind of take a look, there's lots

485
00:27:39.120 --> 00:27:40.080
more similarities

486
00:27:40.080 --> 00:27:44.790
there rather than disc differences, and then here we have the three amateurs,

487
00:27:44.790 --> 00:27:45.440
so we've got

488
00:27:45.440 --> 00:27:53.620
classic, all of them have this cast pattern varying kind of degrees of plateaus

489
00:27:53.620 --> 00:27:54.480
versus

490
00:27:54.480 --> 00:27:59.600
peaks and the downswing peaking orders are all off, but none of them have this

491
00:27:59.600 --> 00:28:00.320
really good

492
00:28:00.320 --> 00:28:08.030
torso continuing to basically green line above the blue line, which is a sign

493
00:28:08.030 --> 00:28:09.280
of a really good

494
00:28:09.280 --> 00:28:15.200
release, so we're going to look at these videos in the other classes as well,

495
00:28:15.200 --> 00:28:18.000
but let's take a quick look, you know I'm sure you know what

496
00:28:18.000 --> 00:28:24.000
grant weight, Henrik Stenson, what those graphs kind of look like visually, but

497
00:28:24.000 --> 00:28:29.120
here's, we'll look at the top one here first, so let's just see what these

498
00:28:29.120 --> 00:28:30.960
graphs kind of look like,

499
00:28:30.960 --> 00:28:37.580
okay so I repositioned it, so this is the graph right here, so if we take it up

500
00:28:37.580 --> 00:28:38.160
towards the top

501
00:28:38.160 --> 00:28:43.880
of the swing, we'll see in the position graphs and some of these other ones,

502
00:28:43.880 --> 00:28:46.000
kind of what's giving

503
00:28:46.000 --> 00:28:52.750
the look, but here we can see transition order where everything, remember the k

504
00:28:52.750 --> 00:28:53.920
inematic sequence

505
00:28:53.920 --> 00:29:00.540
is done by right around here, so that right there is all up till this blue peak

506
00:29:00.540 --> 00:29:01.600
right about there,

507
00:29:02.480 --> 00:29:08.880
so we're really looking at some of these kind of like micro timings, we've got

508
00:29:08.880 --> 00:29:12.000
upper body rotating

509
00:29:12.000 --> 00:29:18.400
a little bit faster, and we can't see the club quite as well here, because he's

510
00:29:18.400 --> 00:29:19.520
, the club is

511
00:29:19.520 --> 00:29:25.440
across the line, so it's kind of at an angle like this, and then he's kind of

512
00:29:25.440 --> 00:29:26.080
going this,

513
00:29:26.080 --> 00:29:31.440
that's where the club is getting a lot of its speed right there, where the club

514
00:29:31.440 --> 00:29:31.840
is getting

515
00:29:31.840 --> 00:29:37.410
accelerated even faster than this arm is pulling, but you can see that the

516
00:29:37.410 --> 00:29:38.720
lower body is moving

517
00:29:38.720 --> 00:29:45.600
kind of the slowest, and then he does kind of peak down there, but you can see

518
00:29:45.600 --> 00:29:46.400
there's the lead

519
00:29:46.400 --> 00:29:51.450
arm kind of getting pulled off the chest as the chest stalls, that's why this

520
00:29:51.450 --> 00:29:52.960
has a look of that

521
00:29:52.960 --> 00:30:02.320
peaking order there, so higher handicap golfer, kind of classic, poor kinematic

522
00:30:02.320 --> 00:30:03.120
sequence right there,

523
00:30:03.120 --> 00:30:14.800
okay second golfer here, again we see a similar transition issue where, okay it

524
00:30:14.800 --> 00:30:15.280
looks like he

525
00:30:15.280 --> 00:30:19.840
was loaded up and he's ready to start down, but everything kind of starts down

526
00:30:19.840 --> 00:30:21.360
together,

527
00:30:22.160 --> 00:30:27.760
possibly that lower body, you know here we can see that plateau before impact,

528
00:30:27.760 --> 00:30:28.960
that's similar,

529
00:30:28.960 --> 00:30:34.000
or that's because of this like lower body stopping as he does that little squat

530
00:30:34.000 --> 00:30:34.240
move,

531
00:30:34.240 --> 00:30:38.800
so it's hard to get a stretch short in that way, which means it's then hard to

532
00:30:38.800 --> 00:30:40.400
fire that lower body,

533
00:30:40.400 --> 00:30:44.910
he does get the lower body to lead compared to the trunk, but you can see, boom

534
00:30:44.910 --> 00:30:46.080
, that club,

535
00:30:47.040 --> 00:30:53.850
the club shaft is moving out that way kind of angrily a lot faster compared to

536
00:30:53.850 --> 00:30:54.640
the forearms

537
00:30:54.640 --> 00:31:00.320
than the rest of the body is moving, now if we took, if we were able to get the

538
00:31:00.320 --> 00:31:01.840
arms to match the body

539
00:31:01.840 --> 00:31:05.500
a little bit better, he actually does have decent peaking where everything is

540
00:31:05.500 --> 00:31:06.480
moving at the similar

541
00:31:06.480 --> 00:31:10.410
rate, you know, compared that to that first golfer we looked at, but we will

542
00:31:10.410 --> 00:31:12.880
see on the way through

543
00:31:12.880 --> 00:31:18.240
that left arm gets pulled around the body and moves faster than the trunk,

544
00:31:18.240 --> 00:31:23.600
so that's kind of some classic,

545
00:31:23.600 --> 00:31:31.780
some classic amateur action there, we'll dive into more of like what makes this

546
00:31:31.780 --> 00:31:33.360
not quite as

547
00:31:33.360 --> 00:31:39.120
functional when we look at some of the position graphs, okay last one we got

548
00:31:39.120 --> 00:31:41.120
Ron here, he always

549
00:31:41.120 --> 00:31:46.360
throws me off with that waggle, okay, so this is the classic kind of casting

550
00:31:46.360 --> 00:31:47.840
pattern where

551
00:31:47.840 --> 00:31:53.530
on its whole, you know, not too bad, lower body looks like it's leading, but if

552
00:31:53.530 --> 00:31:54.160
we look at,

553
00:31:54.160 --> 00:31:59.440
if we break it down and look at this segment, so lead hip to ribs kind of there

554
00:31:59.440 --> 00:32:00.880
, we'll see that

555
00:32:00.880 --> 00:32:06.100
there's no increase in stretch, it's kind of, they're moving together, if we

556
00:32:06.100 --> 00:32:08.080
look at the left

557
00:32:08.080 --> 00:32:12.800
shoulder during that phase, we can see the left shoulder is kind of pulling

558
00:32:12.800 --> 00:32:14.240
down and off, it's not

559
00:32:14.240 --> 00:32:20.280
increasing its stretch, if we look at the wrists up here, this is the most

560
00:32:20.280 --> 00:32:21.600
obvious, you can see that

561
00:32:21.600 --> 00:32:28.000
the club is kind of widening or casting compared to that, so head to toe he's

562
00:32:28.000 --> 00:32:29.520
kind of accelerating

563
00:32:29.520 --> 00:32:36.410
the outer stuff first, and then this is one where visually typically I'll see

564
00:32:36.410 --> 00:32:37.680
that plateau

565
00:32:37.680 --> 00:32:43.760
more with kind of a pronounced chicken wing, I wouldn't have guessed that it

566
00:32:43.760 --> 00:32:44.320
would be that

567
00:32:44.320 --> 00:32:48.440
big of a plateau if I hadn't measured him, so that's where the 3D graphs can

568
00:32:48.440 --> 00:32:49.520
definitely add a

569
00:32:49.520 --> 00:32:54.370
layer of understanding that you might not see from video, so remember I said

570
00:32:54.370 --> 00:32:55.600
the 3D graphs can

571
00:32:55.600 --> 00:33:00.720
help you guide where to look on video, so if I'm looking at this segment, that

572
00:33:00.720 --> 00:33:01.920
's kind of like

573
00:33:01.920 --> 00:33:06.960
right around there, you can see that that left elbow starts to bend a little

574
00:33:06.960 --> 00:33:07.920
bit more,

575
00:33:07.920 --> 00:33:12.720
and the right elbow kind of stalls, so that's going to have a little bit more

576
00:33:12.720 --> 00:33:13.680
of kind of this

577
00:33:13.680 --> 00:33:18.180
pulling force here, which is going to be a lot slower than if I was continuing

578
00:33:18.180 --> 00:33:19.120
to accelerate

579
00:33:19.120 --> 00:33:24.240
kind of down the hill with the club, so that'll probably show up more when we

580
00:33:24.240 --> 00:33:25.200
look at some of the

581
00:33:25.200 --> 00:33:32.160
arm graphs, but this is kind of the classic, consistent, but short golfer

582
00:33:32.160 --> 00:33:32.880
always looking for

583
00:33:32.880 --> 00:33:36.470
more speed, so hopefully you enjoyed this, but if you have any questions about

584
00:33:36.470 --> 00:33:37.360
any of the

585
00:33:37.360 --> 00:33:42.700
the kinematic sequence stuff that we discussed, please comment below or or let

586
00:33:42.700 --> 00:33:43.280
us know and we'll

587
00:33:43.280 --> 00:33:47.360
get out some type of clarification, otherwise enjoy the rest of the series

588
00:33:47.360 --> 00:33:48.240
where we're going

589
00:33:48.240 --> 00:33:54.480
to go through the different position graphs, and how to look at them, and how

590
00:33:54.480 --> 00:33:55.120
to understand

591
00:33:55.120 --> 00:33:59.360
them just like we did this one, so hopefully this will help you really

592
00:33:59.360 --> 00:34:00.240
understand and not

593
00:34:00.240 --> 00:34:04.800
be intimidated whenever you see one of these individual graphs.
