Different excursion of the connected tissue behavior, and therefore he doesn't have as much energy going into the jump. The amount of time that he's applying the forces, they're all the same as what your great vertical jumpers would be, right? But now you don't have the other components.

Yes, the right-handed pitchers throw with their right arm, the left-handed pitchers throw with their left arm. I made a little joke. The lefties are throwing against some of the internal dynamics. The rules don't really change a whole lot. But I would look at them from an archetypical perspective first. He's a wide ISA that has been flattened front to back. You have to get him on his side because it's going to give you the best opportunity to get the anterior posterior expansion and start to create some measure of turn. He's never going to turn like a tall skinny guy. That doesn't mean you don't have to create some of the turn. His helical angles don't give him a lot of verticality. So his release point as a lefty is going to be very horizontal looking under most circumstances. He's always going to have to side bend a little bit, most likely. If you look at some of his old video, chances are you're going to see some IR compensatory strategy anyway. The thing about it is, it's like you don't want to not have any available motion from a relative motion standpoint. Okay, so look at this thing systemically. Don't just look at the arm; just because he throws with his left arm doesn't mean that all the other stuff wasn't contributing in the first place.

I don't know if I can. So, all right. So you have a direction. Let's use the IR. Can we do that? Can we use the IR representation? OK. So as I'm descending into the squat, I have the IR that's going to be coming this away. And so what happens is this is going to compress downward right here. I'm going to increase the load on the femur. That's going to start to bend this because I got to bring IR. It's actually in a squat. It's going to go this way and then towards the center. So it's going to make like an L. L-shaped there like that. So as I descend in the squat, I put more pressure on the head of the femur. It's going to change its angle. So as I change this angle, it's going to create a force against the pelvis. And for me to maintain pressure, I have to push back against it. You see it like that? I have to push back against it. So there's the IR coming up from the ground. Yes. So I started, so I'm standing, I start my descent. I got to put pressure down on. So this is why, this is why the sacrum has to push forward. Like the illing has to move forward because I got to push down on the femur so I can, so I can create an IR position to bring the, the internal rotation centrally. And so I get a shape change through the femur that comes up to promote the shape change into the pelvis. You see it? So I put pressure there. That allows the IR to come this way. I got to push back against it. There's the IR representation there. And then I get the pressurization of the outlet coming up. I get the nutation of the sacrum to squeeze. And then there's my higher pressure representation. As I descend past that, if I want to keep going in the downward direction, the IR representation is going to stop me. That upward pressure is what you use to get out of the squat. So I got to let that go. If I let the motor output decrease, Dante now knows that if I reduce the motor output, I have greater potential for yielding in the connected tissues. That's what happens at the bottom of the squat. And I go back into my ER representation, which is that. To get out of the squat, I got to push this back up so that pelvis will do this. So I can push the IR back down into the femur and stand back up. So in the descent, the IR is coming this way. In the ascent, the IR is going that way.

You're asking how to change the orientation of the muscle? You do that by position. So number one, you have to be put in a position where you don't need concentric action in the limiting musculature.

That's a great thought. It just like until the, if you were at the tail end of a heavy set of work of some description and we're into high threshold motor units and we're getting one muscle fatiguing relative to another one, then we might be able to go, hey, yeah, we're seeing this occur. But if you're at rest or you're at the midpoint or you're just holding a, could be a scapula or a patella or whatever. How much effort is required by those muscles and should they really be contract when you extend to see any difference and it occurred me that that doesn't make sense.
