00:00:00.000 --> 00:00:02.060
In this golf smart insight,

2
00:00:02.060 --> 00:00:05.960
we're going to answer a question about the risk from Michael on Facebook.

3
00:00:05.960 --> 00:00:08.960
So Michael was asking a very technical question,

4
00:00:08.960 --> 00:00:11.380
and if you're a beginning golfer,

5
00:00:11.380 --> 00:00:14.680
please turn this off and just go look at some of the other drills

6
00:00:14.680 --> 00:00:18.560
because this is going to be some high-level theory stuff.

7
00:00:18.560 --> 00:00:21.640
But Michael was asking, on 3D graphs,

8
00:00:21.640 --> 00:00:26.280
you'll frequently see that the trail risk is going to flex through

9
00:00:26.280 --> 00:00:30.440
impact at a rate faster than the left wrist is going to extend.

10
00:00:30.440 --> 00:00:33.080
Now, whether that's one to one,

11
00:00:33.080 --> 00:00:34.160
so they're going the same,

12
00:00:34.160 --> 00:00:35.500
whether it's one to four,

13
00:00:35.500 --> 00:00:38.280
which is about the most that I've ever seen where this is going four times

14
00:00:38.280 --> 00:00:39.640
faster than this one.

15
00:00:39.640 --> 00:00:44.400
That's up to a little bit of different swing styles.

16
00:00:44.400 --> 00:00:49.280
But generally, you're going to see the right wrist going at least twice as fast

17
00:00:49.280 --> 00:00:49.400
as

18
00:00:49.400 --> 00:00:51.600
the left wrist is going to be extending.

19
00:00:51.600 --> 00:00:53.720
So the question is, why?

20
00:00:53.720 --> 00:00:56.220
Well, I don't have the answer,

21
00:00:56.220 --> 00:00:57.840
but I have some things that make sense to me.

22
00:00:57.840 --> 00:01:00.160
So I'll present them to you here in this video.

23
00:01:00.160 --> 00:01:03.920
So anytime I'm looking at a movement,

24
00:01:03.920 --> 00:01:06.520
there's primarily three things that we're going to look at.

25
00:01:06.520 --> 00:01:09.680
We're going to look at path, face, and power.

26
00:01:09.680 --> 00:01:12.520
So how does this movement help me create speed?

27
00:01:12.520 --> 00:01:14.960
How does this movement help me control the path?

28
00:01:14.960 --> 00:01:17.600
How does this movement affect the face to the path?

29
00:01:17.600 --> 00:01:22.440
Now, because this is happening literally inches before impact,

30
00:01:22.440 --> 00:01:27.360
it's probably not going to have a drastic effect on the face and path.

31
00:01:27.360 --> 00:01:32.080
So let's go at power because that's where I think that this difference is

32
00:01:32.080 --> 00:01:33.600
really going to show up more.

33
00:01:33.600 --> 00:01:35.600
So from the power perspective,

34
00:01:35.600 --> 00:01:38.120
there's two things that we need to address.

35
00:01:38.120 --> 00:01:40.840
One, how the heck are we going to create speed?

36
00:01:40.840 --> 00:01:43.160
Two, how are we going to control that speed?

37
00:01:43.160 --> 00:01:47.200
And what I mean by that is how are we going to safely stabilize?

38
00:01:47.200 --> 00:01:49.160
Because in most sports,

39
00:01:49.160 --> 00:01:54.360
there is a follow-through for a reason. It helps you can handle the speed

40
00:01:54.360 --> 00:01:56.520
and the force that you have created with the object,

41
00:01:56.520 --> 00:02:01.720
whether it's my arm and I'm throwing a ball or it's a bat and I'm swinging it.

42
00:02:01.720 --> 00:02:06.520
How am I going to safely handle all this force that's coming back at me

43
00:02:06.520 --> 00:02:08.760
from the implement that I've created?

44
00:02:08.760 --> 00:02:14.040
So one of the studies that I love from baseball,

45
00:02:14.040 --> 00:02:16.600
and I learned about this in one of my Czech classes,

46
00:02:16.600 --> 00:02:22.110
was they took baseball pitchers and they basically monitored their contribution

47
00:02:22.110 --> 00:02:23.720
of speed by joint.

48
00:02:23.720 --> 00:02:26.040
And what they found was,

49
00:02:26.040 --> 00:02:28.920
once you got them up, let's say you were throwing 90 miles an hour,

50
00:02:28.920 --> 00:02:32.280
there was kind of everybody had their own pattern of how much speed they were

51
00:02:32.280 --> 00:02:33.240
creating from their legs,

52
00:02:33.240 --> 00:02:36.280
from their trunk, and from their shoulder, and from their arms.

53
00:02:36.280 --> 00:02:40.280
Well, as they got tired, so as they did through 50, 60 pitches,

54
00:02:40.280 --> 00:02:44.120
the interesting thing was the velocity of what they were throwing the ball

55
00:02:44.120 --> 00:02:45.800
pretty much maintained the same.

56
00:02:45.800 --> 00:02:50.520
The ones who were more prone to injury basically changed their pattern

57
00:02:50.520 --> 00:02:52.520
of how they were creating the speed.

58
00:02:52.520 --> 00:02:55.400
So instead of having let's say 25% coming from the legs,

59
00:02:55.400 --> 00:02:59.000
it was now only 20% and they were getting much more from the arm.

60
00:02:59.000 --> 00:03:01.720
Those players would be much more likely to suffer, you know,

61
00:03:01.720 --> 00:03:04.680
some type of elbow injury when they would get tired.

62
00:03:04.680 --> 00:03:09.800
So the takeaway that I took from this particular study is that

63
00:03:11.160 --> 00:03:15.880
we have kind of this governor in us that allows us to only move something

64
00:03:15.880 --> 00:03:17.880
so fast that we can control it.

65
00:03:17.880 --> 00:03:22.040
It's kind of like when you're sprinting and you come to a downhill

66
00:03:22.040 --> 00:03:25.240
and your legs just start moving so fast that you can't handle it,

67
00:03:25.240 --> 00:03:27.240
you have to kind of throttle yourself back.

68
00:03:27.240 --> 00:03:30.600
So even though you're physically capable of going faster,

69
00:03:30.600 --> 00:03:33.720
because you don't have the stability in place to handle it,

70
00:03:33.720 --> 00:03:37.880
it's going to be a problem in your brain and recognize that and pulls you back.

71
00:03:37.880 --> 00:03:40.840
So how does that apply to this movement in the golf swing?

72
00:03:40.840 --> 00:03:47.480
Well, I think the important question is you've created 100 pounds,

73
00:03:47.480 --> 00:03:51.960
150 pounds of force by getting this light object to swing 100,

74
00:03:51.960 --> 00:03:53.880
you know, 110 miles an hour or whatever.

75
00:03:53.880 --> 00:03:58.600
Well, you have to handle that force in one way or another.

76
00:03:58.600 --> 00:04:03.640
So I always ask people, what muscle pathway would you like to have handling

77
00:04:03.640 --> 00:04:08.200
a 100, 150 pound force going down away from you like so?

78
00:04:08.920 --> 00:04:11.640
And if you look at it from that perspective,

79
00:04:11.640 --> 00:04:15.320
I think it'll start to make sense why the left wrist is going to be

80
00:04:15.320 --> 00:04:18.280
not flexing very, very quickly.

81
00:04:18.280 --> 00:04:21.800
And the reason is the right wrist,

82
00:04:21.800 --> 00:04:27.560
when it flexes and the tricep extends, this is all helping to create speed.

83
00:04:27.560 --> 00:04:30.040
But as we've seen from a lot of golfers,

84
00:04:30.040 --> 00:04:33.000
the right hand is going to be relatively loose.

85
00:04:33.000 --> 00:04:35.720
And in some golfers, it's even coming off the club.

86
00:04:35.720 --> 00:04:39.960
The right hand is in a very poor position for stabilizing that speed.

87
00:04:39.960 --> 00:04:41.480
It's kind of more like baseball,

88
00:04:41.480 --> 00:04:46.120
where you'll typically see after contact with a lot of hitters,

89
00:04:46.120 --> 00:04:49.720
that lead hand or sorry, that trail hand come off the club,

90
00:04:49.720 --> 00:04:52.520
because it's in a poor position to stabilize that force,

91
00:04:52.520 --> 00:04:55.750
where the lead hand is actually in a pretty good position to be able to

92
00:04:55.750 --> 00:04:56.520
stabilize it.

93
00:04:56.520 --> 00:05:00.760
So I think what the lead arm is going to be doing

94
00:05:01.320 --> 00:05:06.200
from about there through till the end of your swing,

95
00:05:06.200 --> 00:05:09.320
is helping to stabilize this force that we've created,

96
00:05:09.320 --> 00:05:11.880
as opposed to contribute much more force.

97
00:05:11.880 --> 00:05:14.120
I think that's going to be coming more from the trail side

98
00:05:14.120 --> 00:05:16.680
based on the movements that the trail side is doing.

99
00:05:16.680 --> 00:05:20.360
So if we're looking at how we're going to stabilize force with the lead arm,

100
00:05:20.360 --> 00:05:23.800
there's a couple of different pathways to get it from my hand to my shoulder,

101
00:05:23.800 --> 00:05:24.280
right?

102
00:05:24.280 --> 00:05:27.000
If I was to supinate, like so,

103
00:05:27.960 --> 00:05:32.040
or if I was to ulnar deviate, that's going to activate muscles down this

104
00:05:32.040 --> 00:05:36.670
inside edge of my arm, which is going to help support kind of my external rot

105
00:05:36.670 --> 00:05:37.880
ators on my shoulder.

106
00:05:37.880 --> 00:05:40.920
So this movement kind of all works well together.

107
00:05:40.920 --> 00:05:43.480
And that movement is going to involve some big muscles,

108
00:05:43.480 --> 00:05:47.640
like my shoulder blade depressors, such as my latin, my mid trap.

109
00:05:47.640 --> 00:05:50.360
So when this weight gets moving very, very quickly,

110
00:05:50.360 --> 00:05:53.480
I'm going to have this shoulder kind of in a good supported position,

111
00:05:53.480 --> 00:05:54.520
so that it can support it.

112
00:05:55.000 --> 00:05:58.840
If I was to have my shoulders kind of shrugged and my elbows out like so,

113
00:05:58.840 --> 00:06:01.320
and I got this weight moving 150 pounds,

114
00:06:01.320 --> 00:06:05.880
it would be the same thing as if I was trying to do a shoulder shrug like this

115
00:06:05.880 --> 00:06:07.400
of 100, 150 pounds.

116
00:06:07.400 --> 00:06:13.560
If I personally was to do that, you know, 80, 90 times a day,

117
00:06:13.560 --> 00:06:17.700
which is roughly around a golf, I would probably end up with shoulder and neck

118
00:06:17.700 --> 00:06:18.680
dysfunctions,

119
00:06:18.680 --> 00:06:22.120
not that I don't already have those, but it would be drastically worse.

120
00:06:23.080 --> 00:06:27.480
So if I was to flex this wrist somewhat aggressively,

121
00:06:27.480 --> 00:06:31.080
it will activate the muscles, and you can see them kind of activate there,

122
00:06:31.080 --> 00:06:33.960
it will activate the muscles more on the top side of my forearm,

123
00:06:33.960 --> 00:06:37.480
which will connect more with my anterior, delt, and upper trap.

124
00:06:37.480 --> 00:06:42.140
So doing this very, very rapidly, you'll see that my arm actually wants to

125
00:06:42.140 --> 00:06:42.840
shrug up,

126
00:06:42.840 --> 00:06:48.280
as opposed to when I go like this, my arm actually wants to kind of shrug down,

127
00:06:48.280 --> 00:06:49.480
or screw into place.

128
00:06:50.040 --> 00:06:55.560
So if I'm going to extend, it wouldn't work well with the rest of my body

129
00:06:55.560 --> 00:07:00.280
as far as destabilizing the force, because the rest of my body,

130
00:07:00.280 --> 00:07:03.320
my arm is going to be extending through that phase,

131
00:07:03.320 --> 00:07:07.800
even if that left wrist is going to be extending a little bit as well.

132
00:07:07.800 --> 00:07:11.240
And it's not really that it's going to be extending,

133
00:07:11.240 --> 00:07:14.200
it's coming from a flex position towards neutral.

134
00:07:15.000 --> 00:07:19.660
It doesn't actually get into its extended position until after I've made

135
00:07:19.660 --> 00:07:19.960
contact

136
00:07:19.960 --> 00:07:21.320
with the golf ball for the most part.

137
00:07:21.320 --> 00:07:26.120
So I think that it's more of a product of how I'm going to stabilize,

138
00:07:26.120 --> 00:07:29.320
and I'm sure that this will lead to more questions, which will be great.

139
00:07:29.320 --> 00:07:34.520
But if we look at kind of how rotation happens in the spine and the rib cage,

140
00:07:34.520 --> 00:07:41.000
where basically if I flex one side of the body and I extend the other,

141
00:07:41.000 --> 00:07:44.980
or if I push away with one side and I pull away with the other, that creates

142
00:07:44.980 --> 00:07:45.480
rotation,

143
00:07:45.480 --> 00:07:50.520
it would start to make sense as to why this right side may be going down and

144
00:07:50.520 --> 00:07:50.760
through,

145
00:07:50.760 --> 00:07:53.080
and this left side would be going back and up.

146
00:07:53.080 --> 00:07:56.520
And if the left side's going back and up, it doesn't make sense for me to

147
00:07:56.520 --> 00:07:58.040
extend this wrist very

148
00:07:58.040 --> 00:08:04.240
aggressively. It may not affect contact, but it would definitely affect how I

149
00:08:04.240 --> 00:08:05.000
would stabilize

150
00:08:05.000 --> 00:08:08.200
the force and the follow through, and I think that would be the bigger issue.
