1
00:00:00.000 --> 00:00:04.880
In this analysis video, we're going to discuss the look of rate of closure.

2
00:00:04.880 --> 00:00:09.860
So I've had a couple of questions about Sasha Mackenzie, Johnson-Claire

3
00:00:09.860 --> 00:00:11.600
presentation regarding

4
00:00:11.600 --> 00:00:13.680
the look of rate of closure.

5
00:00:13.680 --> 00:00:19.930
So I wanted to just do a quick video to kind of put in a couple of thoughts and

6
00:00:19.930 --> 00:00:20.800
give you

7
00:00:20.800 --> 00:00:27.480
a way that you can have a better way of looking at rate of closure on video.

8
00:00:27.480 --> 00:00:31.670
So historically, what a lot of guys have done is looked at two different points

9
00:00:31.670 --> 00:00:31.960
.

10
00:00:31.960 --> 00:00:36.030
So when the club's about parallel and the follow through and when the club is

11
00:00:36.030 --> 00:00:36.440
about

12
00:00:36.440 --> 00:00:40.680
parallel and the downswing, then basically advocating a certain look here in

13
00:00:40.680 --> 00:00:41.320
the follow

14
00:00:41.320 --> 00:00:42.320
through.

15
00:00:42.320 --> 00:00:47.090
Now, this is Phil Mickelson, flipped to a right hand golfer over here as Matt K

16
00:00:47.090 --> 00:00:47.600
uchar.

17
00:00:47.600 --> 00:00:51.610
You can see that they've got the club face pointed roughly in the same

18
00:00:51.610 --> 00:00:52.920
direction compared

19
00:00:52.920 --> 00:00:58.200
to the camera, golf balls started right of their target, so they were both kind

20
00:00:58.200 --> 00:00:58.720
of starting

21
00:00:58.720 --> 00:01:00.440
on a push trajectory.

22
00:01:00.440 --> 00:01:04.200
That means the club face is turned about the same amount between these two

23
00:01:04.200 --> 00:01:04.840
frames.

24
00:01:04.840 --> 00:01:10.320
Well, coming into impact, we're looking at their 3D's of Matt Kuchar as one of

25
00:01:10.320 --> 00:01:11.080
the lower

26
00:01:11.080 --> 00:01:15.640
rate of closures, and Phil Mickelson has one of the higher rate of closure.

27
00:01:15.640 --> 00:01:20.680
So this frame by itself doesn't give you enough to go off of.

28
00:01:20.680 --> 00:01:23.400
And there's a couple reasons that that might happen.

29
00:01:23.400 --> 00:01:29.820
One would be looking at contact location, so when you're looking at where the

30
00:01:29.820 --> 00:01:30.800
golf balls

31
00:01:30.800 --> 00:01:35.660
hit on the face compared to the COG, that can cause some funky twisting looks

32
00:01:35.660 --> 00:01:36.360
in the follow

33
00:01:36.360 --> 00:01:37.680
through.

34
00:01:37.680 --> 00:01:46.160
One other piece that might be relevant is in order to have a lower rate of

35
00:01:46.160 --> 00:01:47.440
closure at

36
00:01:47.440 --> 00:01:52.510
impact oftentimes golfers then are holding off or delaying the things that

37
00:01:52.510 --> 00:01:54.160
close the face.

38
00:01:54.160 --> 00:01:59.110
And so as a result, after impact, they have a rapid spike or a speed up in rate

39
00:01:59.110 --> 00:02:00.080
of closure,

40
00:02:00.080 --> 00:02:05.330
where oftentimes golfers who have a faster rate of closure at impact may have a

41
00:02:05.330 --> 00:02:05.920
look of

42
00:02:05.920 --> 00:02:09.280
a slower rate of closure after impact.

43
00:02:09.280 --> 00:02:14.140
And then lastly, the piece that we can't really tell from here is this is a 3D

44
00:02:14.140 --> 00:02:15.120
image.

45
00:02:15.120 --> 00:02:20.080
So we can look at the distance the club is away from where that T was.

46
00:02:20.080 --> 00:02:24.480
And often golfers who have the lower rate of closure have the later arc width.

47
00:02:24.480 --> 00:02:30.780
And so because their arms are extending more through the shot and the club is

48
00:02:30.780 --> 00:02:31.960
essentially

49
00:02:31.960 --> 00:02:37.770
working away from their body, the club may be further away, even though it's at

50
00:02:37.770 --> 00:02:38.320
the same

51
00:02:38.320 --> 00:02:42.200
angle, therefore it traveled a greater distance and therefore it moved a little

52
00:02:42.200 --> 00:02:42.960
bit slower.

53
00:02:42.960 --> 00:02:48.630
But one of the keys is, okay, this is a hard position right here in order to

54
00:02:48.630 --> 00:02:49.680
really look

55
00:02:49.680 --> 00:02:50.680
at rate of closure.

56
00:02:50.680 --> 00:02:55.240
So where do we want to look?

57
00:02:55.240 --> 00:03:00.110
The classic other position that I've heard discussed is looking pretty much at

58
00:03:00.110 --> 00:03:00.480
when the

59
00:03:00.480 --> 00:03:07.600
club is parallel to the ground or shaft parallel right around here.

60
00:03:07.600 --> 00:03:12.240
And you will see that if we look back at that position.

61
00:03:12.240 --> 00:03:17.840
So probably closest to this frame here, you will see that there's enough of a

62
00:03:17.840 --> 00:03:18.840
difference

63
00:03:18.840 --> 00:03:19.840
here right?

64
00:03:19.840 --> 00:03:22.360
Phil Mickelson's club is pointing above the horizon.

65
00:03:22.360 --> 00:03:24.240
Matt Cooches is already pointing down.

66
00:03:24.240 --> 00:03:28.710
So in order to get the club face to rotate a certain amount around the shaft,

67
00:03:28.710 --> 00:03:29.440
it's going

68
00:03:29.440 --> 00:03:35.260
to have to rotate less covering about the same distance so it's going to move

69
00:03:35.260 --> 00:03:36.200
slower.

70
00:03:36.200 --> 00:03:39.680
But I would challenge you to look even closer.

71
00:03:39.680 --> 00:03:46.880
So whether it's a foot before impact or basically it's close to impact as you

72
00:03:46.880 --> 00:03:48.160
can, seeing how

73
00:03:48.160 --> 00:03:52.520
early they get the face pointed roughly at the golf ball.

74
00:03:52.520 --> 00:03:59.060
So you'll see with Phil through this phase right through here, there's not a

75
00:03:59.060 --> 00:03:59.900
lot of club

76
00:03:59.900 --> 00:04:02.560
face rotation right through here.

77
00:04:02.560 --> 00:04:06.280
There's not a lot of club face rotation, so the club is still pointing well out

78
00:04:06.280 --> 00:04:06.600
to the

79
00:04:06.600 --> 00:04:11.640
right and then it's not until well down here that it starts to straighten and

80
00:04:11.640 --> 00:04:12.520
it's straightening

81
00:04:12.520 --> 00:04:18.480
more from a result of straightening that right arm rather than twisting the

82
00:04:18.480 --> 00:04:19.320
club with

83
00:04:19.320 --> 00:04:20.720
the wrist.

84
00:04:20.720 --> 00:04:24.070
And when you're doing it more from straightening that arm, you're going to tend

85
00:04:24.070 --> 00:04:24.640
to reach that

86
00:04:24.640 --> 00:04:29.060
low or widest point sooner, which is going to decrease the resistance to

87
00:04:29.060 --> 00:04:29.920
twisting and

88
00:04:29.920 --> 00:04:34.240
therefore it's going to twist much higher.

89
00:04:34.240 --> 00:04:40.780
So looking before impact, you can see that roughly when I've used when the club

90
00:04:40.780 --> 00:04:41.200
is in

91
00:04:41.200 --> 00:04:45.470
front of the right foot, if it's still pointing well out to the right, you're

92
00:04:45.470 --> 00:04:46.280
going to have

93
00:04:46.280 --> 00:04:48.800
a higher rate of closure.

94
00:04:48.800 --> 00:04:53.870
Alright, so one of the better places to look at rate of closure is looking at

95
00:04:53.870 --> 00:04:54.520
the face

96
00:04:54.520 --> 00:04:55.520
on view.

97
00:04:55.520 --> 00:04:58.960
Actually one of the best is the overhead view, but that one's really hard to

98
00:04:58.960 --> 00:05:00.480
come by unless

99
00:05:00.480 --> 00:05:03.480
you have your own studio and have a fair amount of pros.

100
00:05:03.480 --> 00:05:07.620
So from the face on view, you can basically look at about how much of the club

101
00:05:07.620 --> 00:05:08.160
face you

102
00:05:08.160 --> 00:05:09.160
can see.

103
00:05:09.160 --> 00:05:15.020
And you'll see over here with Phil, the club face really is apparent well into

104
00:05:15.020 --> 00:05:15.880
the downswing.

105
00:05:15.880 --> 00:05:19.520
So roughly when it's even with his trail foot, you can still see a fair amount

106
00:05:19.520 --> 00:05:20.480
of it.

107
00:05:20.480 --> 00:05:25.440
So now over here on the right, we've got Matt Coocher and you'll see that by

108
00:05:25.440 --> 00:05:26.200
that right

109
00:05:26.200 --> 00:05:31.320
foot, it's really rotating and pointing more at the golf ball.

110
00:05:31.320 --> 00:05:35.240
So right about here where it's even with the right foot, you can see pretty

111
00:05:35.240 --> 00:05:35.920
much the whole

112
00:05:35.920 --> 00:05:36.920
face.

113
00:05:36.920 --> 00:05:39.840
We're here, you can see a lot less of it.

114
00:05:39.840 --> 00:05:44.030
So he's already got it rotated towards the face or towards the golf ball, so

115
00:05:44.030 --> 00:05:44.640
then it's

116
00:05:44.640 --> 00:05:47.840
not going to have to rotate quite as much going into it.

117
00:05:47.840 --> 00:05:51.670
Phil on the other hand still has a fair amount of closing that he's going to

118
00:05:51.670 --> 00:05:53.120
have to do and

119
00:05:53.120 --> 00:05:56.840
he does it really in those last few frames.

120
00:05:56.840 --> 00:06:01.840
So even though they get to a similar look of club face rotation at that follow

121
00:06:01.840 --> 00:06:02.440
through

122
00:06:02.440 --> 00:06:06.120
position, they got there in very different ways.

123
00:06:06.120 --> 00:06:11.880
You can also see from this view, you can see more of that width aspect where he

124
00:06:11.880 --> 00:06:12.440
's reaching

125
00:06:12.440 --> 00:06:15.960
the widest point of his swing sooner.

126
00:06:15.960 --> 00:06:21.620
So when the down the line camera we're looking from this view here, the club is

127
00:06:21.620 --> 00:06:22.280
going to

128
00:06:22.280 --> 00:06:27.960
reach about the same height as Matt Coocher's would a little bit later and that

129
00:06:27.960 --> 00:06:28.720
can also

130
00:06:28.720 --> 00:06:33.240
kind of skew the look of how much the club face is actually rotated.

131
00:06:33.240 --> 00:06:37.790
So when you're trying to analyze club face rate of closure, you want to look at

132
00:06:37.790 --> 00:06:38.240
it just

133
00:06:38.240 --> 00:06:43.840
before impact, not after and sometimes down the line is a harder camera view to

134
00:06:43.840 --> 00:06:44.680
see rather

135
00:06:44.680 --> 00:06:47.120
than face on or overhead.

136
00:06:47.120 --> 00:06:51.390
Now here's a quick image to help with that idea of looking at the club after

137
00:06:51.390 --> 00:06:52.160
impact.

138
00:06:52.160 --> 00:06:56.520
Now these are amateurs hit on the swing vision and you'll see that when it's

139
00:06:56.520 --> 00:06:57.600
hit outside

140
00:06:57.600 --> 00:07:03.800
of the center of mass, it's going to cause a fair amount of club face rotation.

141
00:07:03.800 --> 00:07:07.820
So if you were to take a look at the image right about there, you might say

142
00:07:07.820 --> 00:07:08.520
that that

143
00:07:08.520 --> 00:07:13.030
was held open and therefore be slower, but if you were to look at this image

144
00:07:13.030 --> 00:07:13.680
here, it's

145
00:07:13.680 --> 00:07:15.200
still pointed fairly to the right.

146
00:07:15.200 --> 00:07:20.060
So my guess is that it's higher and unfortunately a lot of the golf swings that

147
00:07:20.060 --> 00:07:20.920
have a higher

148
00:07:20.920 --> 00:07:27.070
rate of closure tend to have more of a toe miss and therefore it's going to

149
00:07:27.070 --> 00:07:27.920
skew the

150
00:07:27.920 --> 00:07:30.280
look of it after impact.

151
00:07:30.280 --> 00:07:36.160
This would be more of the vertical gear effect from hitting it really low on

152
00:07:36.160 --> 00:07:37.200
the face.

153
00:07:37.200 --> 00:07:43.340
So now here we have Jim Furek, another lower rate of closure golfer and you'll

154
00:07:43.340 --> 00:07:44.120
see that

155
00:07:44.120 --> 00:07:48.390
he gets to a very different look here in the follow through than Matt Coocher

156
00:07:48.390 --> 00:07:49.080
did, but

157
00:07:49.080 --> 00:07:52.440
the rate of closure numbers are very similar.

158
00:07:52.440 --> 00:07:57.060
Now you can see that he gets the club through that key zone here pointing at

159
00:07:57.060 --> 00:07:57.960
the golf ball

160
00:07:57.960 --> 00:08:02.740
or closer to the target pretty early, it's not pointed out to the right quite

161
00:08:02.740 --> 00:08:03.440
as much.

162
00:08:03.440 --> 00:08:07.550
From this face on view, again by the time he gets even with that right foot,

163
00:08:07.550 --> 00:08:08.080
you'll

164
00:08:08.080 --> 00:08:12.090
see that the club is pointing more at the golf ball or more at the target so it

165
00:08:12.090 --> 00:08:12.480
's not

166
00:08:12.480 --> 00:08:15.600
going to have to rotate a ton through there.

167
00:08:15.600 --> 00:08:20.550
So I hope this helps you clarify the rate of closure discussion and how you can

168
00:08:20.550 --> 00:08:22.240
use video

169
00:08:22.240 --> 00:08:23.680
to identify.

170
00:08:23.680 --> 00:08:26.930
You're definitely not going to be able to get a numeric range as far as how

171
00:08:26.930 --> 00:08:27.400
fast you're

172
00:08:27.400 --> 00:08:32.600
actually closing, but you may be able to categorize yourself as more of a high

173
00:08:32.600 --> 00:08:33.800
rate, low rate,

174
00:08:33.800 --> 00:08:34.800
medium rate.

175
00:08:34.800 --> 00:08:36.640
So here's one last example.

176
00:08:36.640 --> 00:08:41.010
By looking at rate of closure in this way, you'll be able to understand why

177
00:08:41.010 --> 00:08:41.680
Jordan's

178
00:08:41.680 --> 00:08:47.710
beef has more of a medium rate of closure, he's not even really on the super

179
00:08:47.710 --> 00:08:48.800
low side,

180
00:08:48.800 --> 00:08:53.390
even though he has that kind of hold off look in the follow through that often

181
00:08:53.390 --> 00:08:54.440
gets attributed

182
00:08:54.440 --> 00:08:56.320
to a lower rate of closure.

183
00:08:56.320 --> 00:08:59.420
You can see that the club face is pointing a bit out to the right, not as much

184
00:08:59.420 --> 00:09:00.080
as Phil's,

185
00:09:00.080 --> 00:09:05.840
not as low as Furex or Kuchar, he's kind of more in the middle of the pack.

186
00:09:05.840 --> 00:09:09.700
From that face on view, you can still see a bit of the club face as it

187
00:09:09.700 --> 00:09:10.840
approaches more

188
00:09:10.840 --> 00:09:14.840
that right foot and then it closes there on the way through.

189
00:09:14.840 --> 00:09:18.860
So by using a more of a scientific or critical eye, hopefully you can

190
00:09:18.860 --> 00:09:20.160
understand a little

191
00:09:20.160 --> 00:09:22.400
bit better the rate of closure discussion.
