00:00:00.530 --> 00:00:03.300
this call smart insight is understanding

00:00:03.300 --> 00:00:06.560
pressure plates versus force plates so

00:00:06.560 --> 00:00:09.030
pressure plates force plates there are

00:00:09.030 --> 00:00:10.590
different ways of measuring how the feet

00:00:10.590 --> 00:00:13.440
interact with the ground now golf

00:00:13.440 --> 00:00:15.660
instructors have long talked about how

00:00:15.660 --> 00:00:17.070
you want to have your feet working

00:00:17.070 --> 00:00:18.420
against the ground now you want your

00:00:18.420 --> 00:00:20.970
swing to start from the ground up we've

00:00:20.970 --> 00:00:23.070
got cool ways to potentially measure it

00:00:23.070 --> 00:00:24.869
but you need to understand how each of

00:00:24.869 --> 00:00:26.699
these systems is measuring either

00:00:26.699 --> 00:00:29.660
pressure or force so they can get too

00:00:29.660 --> 00:00:32.040
confused by the information that you get

00:00:32.040 --> 00:00:34.649
back from the analysis so first let's

00:00:34.649 --> 00:00:36.570
talk about pressure plates the most

00:00:36.570 --> 00:00:38.219
common one would be body track but

00:00:38.219 --> 00:00:42.300
pressure plates are just taking where my

00:00:42.300 --> 00:00:45.210
body is pressing into this mat and then

00:00:45.210 --> 00:00:50.340
averaging it so let's say I've got kind

00:00:50.340 --> 00:00:55.110
of a scale all right if I've got my feet

00:00:55.110 --> 00:00:58.379
along this scale I could have a hundred

00:00:58.379 --> 00:00:59.850
percent on the right I could have a

00:00:59.850 --> 00:01:01.260
hundred percent on the left

00:01:01.260 --> 00:01:03.059
I could have my body over here but be

00:01:03.059 --> 00:01:05.729
pushing down with that the trail foot

00:01:05.729 --> 00:01:07.320
and it would shift this way along the

00:01:07.320 --> 00:01:09.060
scale or I could be over here and

00:01:09.060 --> 00:01:11.610
pushing down with that front foot and

00:01:11.610 --> 00:01:13.530
have it shift towards the target so it's

00:01:13.530 --> 00:01:15.869
not really looking at where my weight is

00:01:15.869 --> 00:01:18.299
or where my mass is it's looking at

00:01:18.299 --> 00:01:20.880
where I'm pressing so for instance I

00:01:20.880 --> 00:01:22.860
could be in a good driver position and

00:01:22.860 --> 00:01:25.229
have this foot almost off the ground so

00:01:25.229 --> 00:01:27.240
we would show that a hundred percent of

00:01:27.240 --> 00:01:29.509
my pressure is over on the front foot

00:01:29.509 --> 00:01:32.400
that could be a little confusing if you

00:01:32.400 --> 00:01:34.470
saw someone who is in this position and

00:01:34.470 --> 00:01:36.930
you said and they said that they had a

00:01:36.930 --> 00:01:39.240
hundred percent of their weight in that

00:01:39.240 --> 00:01:41.610
front foot so pressure plates is really

00:01:41.610 --> 00:01:43.020
just taking the average of how I'm

00:01:43.020 --> 00:01:45.000
pushing down and putting it in this

00:01:45.000 --> 00:01:48.479
left-to-right scale the next step up

00:01:48.479 --> 00:01:50.460
would be looking at force plates so a

00:01:50.460 --> 00:01:52.170
force plate would be looking at

00:01:52.170 --> 00:01:55.020
something like a swing catalyst so swing

00:01:55.020 --> 00:01:57.930
catalyst is able to see the direction

00:01:57.930 --> 00:02:00.540
and the amplitude of where I'm pressing

00:02:00.540 --> 00:02:03.840
so they will typically the swing

00:02:03.840 --> 00:02:05.759
catalyst is one plate and that's an

00:02:05.759 --> 00:02:07.920
important thing to understand because

00:02:07.920 --> 00:02:11.819
since it's a it's a one plate system it

00:02:11.819 --> 00:02:13.600
basically takes

00:02:13.600 --> 00:02:15.880
what both of my feet are doing and then

00:02:15.880 --> 00:02:18.370
presents the net some not what each foot

00:02:18.370 --> 00:02:21.190
is doing the next wave will be in order

00:02:21.190 --> 00:02:23.290
to really see what each foot is doing

00:02:23.290 --> 00:02:27.490
you need two different force plates so

00:02:27.490 --> 00:02:29.830
in the pressure example I could be

00:02:29.830 --> 00:02:32.710
pushing let's say I'm pushing I'm just

00:02:32.710 --> 00:02:34.390
standing here so my weight is in the

00:02:34.390 --> 00:02:35.350
center just like this

00:02:35.350 --> 00:02:38.170
well I'm pushing down and this doesn't

00:02:38.170 --> 00:02:40.540
know if I'm pushing down in any

00:02:40.540 --> 00:02:42.160
different direction it's just measuring

00:02:42.160 --> 00:02:44.770
how much I'm pushing down the force

00:02:44.770 --> 00:02:46.450
plate somewhere dough swing catalyst

00:02:46.450 --> 00:02:48.550
would be able to tell me how much or

00:02:48.550 --> 00:02:51.580
what direction I'm pushing now the

00:02:51.580 --> 00:02:53.650
problem is again because it's one plate

00:02:53.650 --> 00:02:55.690
let's say it's looking at the amount of

00:02:55.690 --> 00:02:58.900
left to right movement I don't know if

00:02:58.900 --> 00:03:02.380
let's say let's say I'm here my setup

00:03:02.380 --> 00:03:07.180
and then as I go to to take away it says

00:03:07.180 --> 00:03:10.270
that I am moving or I'm applying a force

00:03:10.270 --> 00:03:13.150
in that direction which push propels my

00:03:13.150 --> 00:03:15.310
body in this direction I don't know if

00:03:15.310 --> 00:03:17.290
I'm doing it because I'm pushing with

00:03:17.290 --> 00:03:18.910
the left foot or if I'm pushing with the

00:03:18.910 --> 00:03:24.400
right foot so in the easy kind of way to

00:03:24.400 --> 00:03:25.990
see where this complication could come

00:03:25.990 --> 00:03:27.400
up would be if you're looking at the

00:03:27.400 --> 00:03:30.190
amount of twisting right so the torque

00:03:30.190 --> 00:03:33.460
graph or the torque data will show you

00:03:33.460 --> 00:03:36.640
how much my body is creating let's say

00:03:36.640 --> 00:03:40.180
torque in the right direction in order

00:03:40.180 --> 00:03:42.520
to propel myself in the leftward

00:03:42.520 --> 00:03:45.430
direction right so it doesn't

00:03:45.430 --> 00:03:47.560
necessarily it or it doesn't know if

00:03:47.560 --> 00:03:50.470
it's because I'm twisting my right foot

00:03:50.470 --> 00:03:51.970
twisting my left foot

00:03:51.970 --> 00:03:54.970
I could be pushing linearly and creating

00:03:54.970 --> 00:03:57.460
that torque there are lots of different

00:03:57.460 --> 00:04:01.060
combinations that could create the exact

00:04:01.060 --> 00:04:04.300
same pattern so what we really need is

00:04:04.300 --> 00:04:06.100
what the research laboratories have

00:04:06.100 --> 00:04:08.860
which is individual platforms underneath

00:04:08.860 --> 00:04:12.040
each foot so then I could see with this

00:04:12.040 --> 00:04:15.190
if this one foot is it pushing to the

00:04:15.190 --> 00:04:17.320
left to the right what what where is the

00:04:17.320 --> 00:04:19.239
pressure within the foot what direction

00:04:19.239 --> 00:04:21.220
am i pushing what amplitude or what

00:04:21.220 --> 00:04:24.280
magnitude it would give me a whole lot

00:04:24.280 --> 00:04:26.740
of information so you want to be careful

00:04:26.740 --> 00:04:27.389
with

00:04:27.389 --> 00:04:29.969
interpreting too much from these force

00:04:29.969 --> 00:04:33.360
graphs because especially with like a

00:04:33.360 --> 00:04:36.120
body track or a swing catalyst the way

00:04:36.120 --> 00:04:37.639
that they are currently measuring

00:04:37.639 --> 00:04:40.409
there's a lot that could be

00:04:40.409 --> 00:04:42.599
misinterpreted or by either the

00:04:42.599 --> 00:04:45.330
practitioner or by your body so if I say

00:04:45.330 --> 00:04:47.009
get all your pressure into your lead

00:04:47.009 --> 00:04:48.449
foot you may think that you have to

00:04:48.449 --> 00:04:50.159
shift your weight it could be just

00:04:50.159 --> 00:04:53.159
pushing harder if I say that you need to

00:04:53.159 --> 00:04:54.990
twist against the ground more because

00:04:54.990 --> 00:04:57.120
you're not twisting enough I'm not

00:04:57.120 --> 00:04:59.129
telling you how to do it from the right

00:04:59.129 --> 00:05:01.020
foot to do it from the left foot to do

00:05:01.020 --> 00:05:04.740
it from a forced couple I'm hoping that

00:05:04.740 --> 00:05:06.750
you'll be able to match the data in the

00:05:06.750 --> 00:05:08.250
proper way and that's not always the

00:05:08.250 --> 00:05:10.889
case so if you like the way that we

00:05:10.889 --> 00:05:13.469
analyze and breakdown the current trends

00:05:13.469 --> 00:05:14.969
