S…
Speaker 1 (PArabal, video 7)
We are going to watch this interesting gait cycle
0:04
S…
Speaker 1 (PArabal, video 7)
and then I am going to give you my breakdown about it.
0:08
S…
Speaker 1 (PArabal, video 7)
So let's see.
0:09
S…
Speaker 1 (PArabal, video 7)
Okay.
0:24
S…
Speaker 1 (PArabal, video 7)
Can you spot the asymmetries?
0:26
S…
Speaker 1 (PArabal, video 7)
Let's start.
0:27
S…
Speaker 1 (PArabal, video 7)
We are going to start with the frontal
0:32
S…
Speaker 1 (PArabal, video 7)
plane, lateral flexion.
0:33
S…
Speaker 1 (PArabal, video 7)
You can see that there are some asymmetries in
0:37
S…
Speaker 1 (PArabal, video 7)
the lateral flexion and most importantly,
0:40
S…
Speaker 1 (PArabal, video 7)
they all come.
0:42
S…
Speaker 1 (PArabal, video 7)
From the same pattern of compensation,
0:44
S…
Speaker 1 (PArabal, video 7)
if you see the lateral flexion to the left is mostly
0:49
S…
Speaker 1 (PArabal, video 7)
lumbar dominant.
0:50
S…
Speaker 1 (PArabal, video 7)
This is probably,
0:51
S…
Speaker 1 (PArabal, video 7)
let's take the point where the lateral flexion to the left is
0:55
S…
Speaker 1 (PArabal, video 7)
maximum.
0:56
S…
Speaker 1 (PArabal, video 7)
There's going to be somewhere around here.
0:57
S…
Speaker 1 (PArabal, video 7)
You see this segment of the spine is straight.
1:00
S…
Speaker 1 (PArabal, video 7)
All the lateral flexion is concentrated pretty much in this
1:04
S…
Speaker 1 (PArabal, video 7)
few vertebra,
1:06
S…
Speaker 1 (PArabal, video 7)
two or three vertebra doing most of the lateral flexion.
1:08
S…
Speaker 1 (PArabal, video 7)
The lateral flexion to the right,
1:11
S…
Speaker 1 (PArabal, video 7)
however, is different.
1:14
S…
Speaker 1 (PArabal, video 7)
This is probably the maximum lateral flexion to the right.
1:17
S…
Speaker 1 (PArabal, video 7)
It's a little bit higher on the spine,
1:20
S…
Speaker 1 (PArabal, video 7)
but also is not as
1:24
S…
Speaker 1 (PArabal, video 7)
prominent as on the left side.
1:27
S…
Speaker 1 (PArabal, video 7)
So you see this in movement.
1:30
S…
Speaker 1 (PArabal, video 7)
It's going to look like this.
1:32
S…
Speaker 1 (PArabal, video 7)
So what's going
1:37
S…
Speaker 1 (PArabal, video 7)
to happen is that the ribcage is going to shift to the left.
1:41
S…
Speaker 1 (PArabal, video 7)
If you have a lateral flexion at the bottom to the left and lateral flexion at the top
1:45
S…
Speaker 1 (PArabal, video 7)
to the right.
1:48
S…
Speaker 1 (PArabal, video 7)
The ribcage is going to shift to the left
1:52
S…
Speaker 1 (PArabal, video 7)
and you can see it here.
1:53
S…
Speaker 1 (PArabal, video 7)
Let's see it in movement actually.
1:54
S…
Speaker 1 (PArabal, video 7)
See how this part of the ribcage falls outside of
1:59
S…
Speaker 1 (PArabal, video 7)
the hip bone and it doesn't do the same movement to the right side.
2:03
S…
Speaker 1 (PArabal, video 7)
So basically he needs more length on
2:08
S…
Speaker 1 (PArabal, video 7)
the lateral lines at the bottom of the thorax on
2:12
S…
Speaker 1 (PArabal, video 7)
the left side and at the top of the thorax on the right side.
2:18
S…
Speaker 1 (PArabal, video 7)
to make this more even so the top of the lateral flexion has to
2:22
S…
Speaker 1 (PArabal, video 7)
the top of the ribcage has to do more lateral flexion
2:26
S…
Speaker 1 (PArabal, video 7)
to the left and the lumbar has to do more lateral flexion
2:30
S…
Speaker 1 (PArabal, video 7)
to the right to make this more symmetrical the lumbar
2:35
S…
Speaker 1 (PArabal, video 7)
he's compressing when landing this is happening on both sides you see
2:39
S…
Speaker 1 (PArabal, video 7)
that there is a little bit up here you see this
2:44
S…
Speaker 1 (PArabal, video 7)
folds on the skin when he lands here again
2:53
S…
Speaker 1 (PArabal, video 7)
Holds on the skin.
2:54
S…
Speaker 1 (PArabal, video 7)
It's happening more on the right side though.
2:55
S…
Speaker 1 (PArabal, video 7)
But this is a result of
2:59
S…
Speaker 1 (PArabal, video 7)
him landing on his foot.
3:01
S…
Speaker 1 (PArabal, video 7)
So you can see that he lands,
3:04
S…
Speaker 1 (PArabal, video 7)
impact is at his ankle,
3:06
S…
Speaker 1 (PArabal, video 7)
impact is at the knee,
3:07
S…
Speaker 1 (PArabal, video 7)
hip,
3:09
S…
Speaker 1 (PArabal, video 7)
and then it goes up to the lumbar.
3:11
S…
Speaker 1 (PArabal, video 7)
This is a reaction of his body.
3:13
S…
Speaker 1 (PArabal, video 7)
This is probably because of some
3:17
S…
Speaker 1 (PArabal, video 7)
lacking of tension on the posterior chain,
3:20
S…
Speaker 1 (PArabal, video 7)
probably at the calves and feet level.
3:23
S…
Speaker 1 (PArabal, video 7)
When you see him running here from the side,
3:27
S…
Speaker 1 (PArabal, video 7)
you see that his arch is too high
3:33
S…
Speaker 1 (PArabal, video 7)
and the arch doesn't open.
3:35
S…
Speaker 1 (PArabal, video 7)
So that's probably one of the deficiencies that is making him
3:39
S…
Speaker 1 (PArabal, video 7)
not reduce the impact of his landing.
3:42
S…
Speaker 1 (PArabal, video 7)
The arch has to move.
3:44
S…
Speaker 1 (PArabal, video 7)
It has to raise and it has to drop.
3:47
S…
Speaker 1 (PArabal, video 7)
It has to do the two ranges of motion.
3:51
S…
Speaker 1 (PArabal, video 7)
Okay, let's look at the transverse plane.
3:54
S…
Speaker 1 (PArabal, video 7)
We can also see some asymmetries here.
3:56
S…
Speaker 1 (PArabal, video 7)
You can see him running.
3:58
S…
Speaker 1 (PArabal, video 7)
The rotation to the right is a lot more prominent than the rotation
4:02
S…
Speaker 1 (PArabal, video 7)
to the left.
4:03
S…
Speaker 1 (PArabal, video 7)
You can also see it on the arm swing.
4:07
S…
Speaker 1 (PArabal, video 7)
This arm is going way more behind than
4:11
S…
Speaker 1 (PArabal, video 7)
the left arm.
4:12
S…
Speaker 1 (PArabal, video 7)
You can see it more on the
4:16
S…
Speaker 1 (PArabal, video 7)
side view also.
4:17
S…
Speaker 1 (PArabal, video 7)
And the rear cage is rotating more to the side.
4:20
S…
Speaker 1 (PArabal, video 7)
So that's one asymmetry.
4:25
S…
Speaker 1 (PArabal, video 7)
On the transverse plane,
4:26
S…
Speaker 1 (PArabal, video 7)
there is a limited pelvis rotation and also femur rotation
4:30
S…
Speaker 1 (PArabal, video 7)
as a consequence.
4:31
S…
Speaker 1 (PArabal, video 7)
So the pelvis doesn't rotate as much.
4:33
S…
Speaker 1 (PArabal, video 7)
If the pelvis doesn't rotate,
4:35
S…
Speaker 1 (PArabal, video 7)
it's going to do another movement.
4:36
S…
Speaker 1 (PArabal, video 7)
And in this case,
4:37
S…
Speaker 1 (PArabal, video 7)
it's going to be a lateral tilt.
4:40
S…
Speaker 1 (PArabal, video 7)
And it's going to happen more when he lands on
4:44
S…
Speaker 1 (PArabal, video 7)
his foot.
4:45
S…
Speaker 1 (PArabal, video 7)
The thorax
4:49
S…
Speaker 1 (PArabal, video 7)
and the arm sequence is off.
4:52
S…
Speaker 1 (PArabal, video 7)
Usually on elite sprinters,
4:54
S…
Speaker 1 (PArabal, video 7)
let's say that the rib cage is rotating to the left,
4:57
S…
Speaker 1 (PArabal, video 7)
this arm is,
4:58
S…
Speaker 1 (PArabal, video 7)
most of the rotation is going to be swinging forward.
5:01
S…
Speaker 1 (PArabal, video 7)
When he's rotating to the left,
5:02
S…
Speaker 1 (PArabal, video 7)
the arm is swinging back and it has to go forward.
5:05
S…
Speaker 1 (PArabal, video 7)
So the arm and rib cage sequencing,
5:08
S…
Speaker 1 (PArabal, video 7)
it's off,
5:10
S…
Speaker 1 (PArabal, video 7)
it's backwards most of the time.
5:13
S…
Speaker 1 (PArabal, video 7)
That's not going to allow him to do a proper force transfer between
5:17
S…
Speaker 1 (PArabal, video 7)
his arm swing and his ribcage movement.
5:21
S…
Speaker 1 (PArabal, video 7)
On the sagittal plane,
5:22
S…
Speaker 1 (PArabal, video 7)
he has a rigid upper thorax.
5:24
S…
Speaker 1 (PArabal, video 7)
So you can see it here.
5:27
S…
Speaker 1 (PArabal, video 7)
This segment,
5:28
S…
Speaker 1 (PArabal, video 7)
it pretty much doesn't move that much.
5:32
S…
Speaker 1 (PArabal, video 7)
So that's one of the things that's happening.
5:36
S…
Speaker 1 (PArabal, video 7)
If we see it from behind,
5:38
S…
Speaker 1 (PArabal, video 7)
that
5:43
S…
Speaker 1 (PArabal, video 7)
segment doesn't move as much.
5:44
S…
Speaker 1 (PArabal, video 7)
That segment doesn't do extension.
5:48
S…
Speaker 1 (PArabal, video 7)
And there is also limited hip extension on the right leg.
5:52
S…
Speaker 1 (PArabal, video 7)
And he compensates by doing a lumbar extension
5:56
S…
Speaker 1 (PArabal, video 7)
instead.
5:57
S…
Speaker 1 (PArabal, video 7)
So let's watch.
5:58
S…
Speaker 1 (PArabal, video 7)
You see that when he's swinging this leg back,
6:01
S…
Speaker 1 (PArabal, video 7)
his lumbar is doing extension,
6:03
S…
Speaker 1 (PArabal, video 7)
right?
6:04
S…
Speaker 1 (PArabal, video 7)
When he's doing it,
6:05
S…
Speaker 1 (PArabal, video 7)
I'm going to put this actually slower and see if I can slow it down.
6:08
S…
Speaker 1 (PArabal, video 7)
When we slow it down using AI,
6:10
S…
Speaker 1 (PArabal, video 7)
it looks a little bit funny sometimes.
6:14
S…
Speaker 1 (PArabal, video 7)
You see how much this lumbar is doing extension when he swings his
6:18
S…
Speaker 1 (PArabal, video 7)
leg back?
6:18
S…
Speaker 1 (PArabal, video 7)
That doesn't happen with the left leg.
6:21
S…
Speaker 1 (PArabal, video 7)
So this leg has to do more extension.
6:25
S…
Speaker 1 (PArabal, video 7)
You see?
6:27
S…
Speaker 1 (PArabal, video 7)
And hyperextension when he steps with the right leg.
6:33
S…
Speaker 1 (PArabal, video 7)
is not the same as when he steps with the left leg.
6:36
S…
Speaker 1 (PArabal, video 7)
It's not that this hyperextension with the lumbar shouldn't happen,
6:40
S…
Speaker 1 (PArabal, video 7)
but the thing is that he's doing the hyperextension because the
6:44
S…
Speaker 1 (PArabal, video 7)
hip is not extending.
6:44
S…
Speaker 1 (PArabal, video 7)
Usually when you're sprinting,
6:46
S…
Speaker 1 (PArabal, video 7)
the hip does extension first,
6:48
S…
Speaker 1 (PArabal, video 7)
the lumbar does extension after,
6:50
S…
Speaker 1 (PArabal, video 7)
and the thoracic does a hyperextension last.
6:53
S…
Speaker 1 (PArabal, video 7)
But he's doing the hyperextension of the lumbar in the beginning.
6:57
S…
Speaker 1 (PArabal, video 7)
That's one thing.
7:01
S…
Speaker 1 (PArabal, video 7)
On the lower limbs,
7:02
S…
Speaker 1 (PArabal, video 7)
limited knee flexion on the left side.
7:05
S…
Speaker 1 (PArabal, video 7)
We can probably see it better here.
7:06
S…
Speaker 1 (PArabal, video 7)
The right side,
7:08
S…
Speaker 1 (PArabal, video 7)
actually, the knee flexion on the right side is not too bad.
7:11
S…
Speaker 1 (PArabal, video 7)
He could do a little bit more.
7:12
S…
Speaker 1 (PArabal, video 7)
But on the left side,
7:13
S…
Speaker 1 (PArabal, video 7)
it's not the same.
7:14
S…
Speaker 1 (PArabal, video 7)
It's a little bit less.
7:15
S…
Speaker 1 (PArabal, video 7)
So that's something else.
7:17
S…
Speaker 1 (PArabal, video 7)
Right.
7:20
S…
Speaker 1 (PArabal, video 7)
Making better.
7:21
S…
Speaker 1 (PArabal, video 7)
On the left side.
7:23
S…
Speaker 1 (PArabal, video 7)
It's not that bad,
7:26
S…
Speaker 1 (PArabal, video 7)
though.
7:32
S…
Speaker 1 (PArabal, video 7)
foot and ankle hypermobility well hypermobility on the
7:36
S…
Speaker 1 (PArabal, video 7)
arch is too far up he raises his arch too much
7:40
S…
Speaker 1 (PArabal, video 7)
so that's something that he has to
7:44
S…
Speaker 1 (PArabal, video 7)
work on let's see the upper limbs
7:49
S…
Speaker 1 (PArabal, video 7)
there are asymmetries in the arm swing and most notably the
7:53
S…
Speaker 1 (PArabal, video 7)
right arm does too much extension shoulder extension
7:57
S…
Speaker 1 (PArabal, video 7)
doesn't do enough shoulder flexion the left arm doesn't doesn't do
8:02
S…
Speaker 1 (PArabal, video 7)
shoulder extension and it does too much flexion because also
8:07
S…
Speaker 1 (PArabal, video 7)
his ribcage rotates too much to the right so you can see that this
8:11
S…
Speaker 1 (PArabal, video 7)
arm swings back more this arm swings forward more is
8:15
S…
Speaker 1 (PArabal, video 7)
it probably a little bit better from the side view see
8:20
S…
Speaker 1 (PArabal, video 7)
it has
8:25
S…
Speaker 1 (PArabal, video 7)
one thing and
8:27
S…
Speaker 1 (PArabal, video 7)
That makes his scapula hypermobile.
8:30
S…
Speaker 1 (PArabal, video 7)
This scapula retracts too much.
8:32
S…
Speaker 1 (PArabal, video 7)
This scapula protracts too much.
8:35
S…
Speaker 1 (PArabal, video 7)
Also,
8:36
S…
Speaker 1 (PArabal, video 7)
the elbows.
8:37
S…
Speaker 1 (PArabal, video 7)
He needs to do more elbow extension,
8:39
S…
Speaker 1 (PArabal, video 7)
especially on the left side.
8:41
S…
Speaker 1 (PArabal, video 7)
The left side is pretty bad on extension.
8:43
S…
Speaker 1 (PArabal, video 7)
It looks kind of
8:48
S…
Speaker 1 (PArabal, video 7)
like he's walking with an arm brace on his left side.
8:50
S…
Speaker 1 (PArabal, video 7)
When you run,
8:51
S…
Speaker 1 (PArabal, video 7)
that arm has to swing,
8:52
S…
Speaker 1 (PArabal, video 7)
has to do extension,
8:53
S…
Speaker 1 (PArabal, video 7)
has to do flation.
8:56
S…
Speaker 1 (PArabal, video 7)
And what else?
8:57
S…
Speaker 1 (PArabal, video 7)
And there is poor force transfer between the arms
9:01
S…
Speaker 1 (PArabal, video 7)
and the thorax.
9:02
S…
Speaker 1 (PArabal, video 7)
Especially when he rotates the ribcage to
9:06
S…
Speaker 1 (PArabal, video 7)
the left.
9:07
S…
Speaker 1 (PArabal, video 7)
Actually on both sides,
9:09
S…
Speaker 1 (PArabal, video 7)
but more when he rotates the ribcage to the left.
9:11
S…
Speaker 1 (PArabal, video 7)
And that comes from the arm sequencing being
9:15
S…
Speaker 1 (PArabal, video 7)
a little bit off.
9:16
S…
Speaker 1 (PArabal, video 7)
So we have seen that previously with Elite Sprinters.
9:20
S…
Speaker 1 (PArabal, video 7)
How that works.
9:24
S…
Speaker 1 (PArabal, video 7)
And I think that's it for this movement audit.
