The lack of oxygen. Lack of oxygen.

The female is party is he are that.

Bottom back.

There you go. That's it. Right there. Yes. So that's why they land there. If I wanted to push them back to the starting condition, I want to push them back to starting.

Yeah.

Yes. Because what you're not getting under that circumstance, the eccentric orientation would cause the joint change of position, but the timing would be associated with the connective tissue behavior.

Okay. Yeah. So now you just have to look at this and say, okay, where is the restriction that is not allowing this to turn like I got the femur to turn. Right. Okay. It'll take some thinking. Break out your favorite anatomy book and start looking at the stuff that crosses through there. And you go, okay, I got to reduce that muscle orientation. I don't have enough eccentric orientation to allow the normal capture of IR. That's why you can't get the foot context. It's because I don't have IR that's coming through the foot from heel to forefoot. I got IR that's dropping dead right on that first metatarsal phalangeal joint. It's going too fast. I got to slow her down. Well, how do you slow it down? I have to get the relative motions back through the entire foot. Once you get that rotation back, now you capture foot contact. Now you get a tibia that will actually turn into internal rotation and allow the knee to bend. But until then, don't try to bend your knee.

OK, so like I said, that expression right there lends me to maybe you just need a little bit more elevation. But number two, think about what you're also trying to do. So you're going to use a reduced IR foot position, and you're going to drive an IR on top of it. And again, I'm OK with the conflict because I understand what you're trying to do. Again, that might be part of the issue. What you may need to do is actually do this in pieces. Think about the degree of coordinate of capabilities of this human being that has no sensation of how that foot should move in the first part. And so you may have to account for that. Right. Get the rear foot in a really good position first. Um, you may be able to actually capture some of the IR that you're going after just by doing like translating the tibia over the foot with the max P foot representation. Right. Okay. That may actually be helpful. You could get some tibial IR relative to the starting conditions. That actually might buy you the IR more proximal as well. Either way, like if you capture it that way, awesome. If I get the better foot and tibial representation, remember, you got to stack all this stuff up on top of that foot, it might make the job easier.

Yes.

Okay. Okay.

Gotcha. And then for something dynamic like a squat as we were talking about, it would be like ball between the knee versus band. One way to look at it is potentially just like what part of the range are they having trouble accessing.

Yes. So you can constrain it because a lot of times that shows up in context. For instance, take two sprinters. One has great acceleration, lesser top speed. One has lesser acceleration, but great top speed. Both can run the exact same time and yet achieve the outcome in a different way. Take two people with vertical jumps that are equivalent. Then you look at ground contact time. Again, there can be a difference in the duration of force application and yet still achieve the same result. One might need more time to do it. One might need lesser time to do it. If I increase the duration of one too long, they're going to spend too much time on the ground. They won't be able to store and release the energy. If I reduce the ground contact time and I don't have time for peak force, I won't jump as high.

Yeah. It is, it is, it is the, right. You can get everything right and then, and then you do it too long and you stick them to the ground. Right. Absolutely. Absolutely. So, okay, so let's look at this from a couple of perspectives. So don't just think about the duration of the overcoming element, okay? You think about the rise, okay? And then how quickly can they turn it off? Right. When you look at, when you look at movement efficiency, the ability to go from peak force to low to low no force, there's your velocity, right? Right. Right. And I was, I always go back to, uh, uh, Stu McGill has, has stuff on this where he was looking at martial artists and kicking. And, um, he had him, all wired up and the MG was on their trunk, I believe. And I think it was George St. Pierre, don't quote me. But I think it was. And there's two peaks of force output in something like that. So when they initiate the kick, there's a very high force, and then it disappears. Because what this is is the leg going through space very quickly, which means there has to be as little force as possible. And then at contact, there's another peak force. So you have to look at it from that perspective. It's like, OK, I need you to be able to ramp this baby up very, very quickly and then shut it down very quickly and then sustain for whatever it is you determine is the optimal time frame.

Yeah, where are we talking on the left foot?

There is no ideal.

You didn't have any internal rotation.

It's not going to go like that. In my observation so far, this has typically been in narrows. It was one of the other reasons that I thought perhaps she was a narrow, albeit she's obviously wide, but I watch—do you get that often in wides as well when you press down hard enough?

That makes a lot of sense. Got some stuff.

What makes muscles?

You're up in the left.

Okay, so that is, yes, it's really helpful. I also watched a video where you explained the time limit about force. For power lifters, they don't need to have really good power output because they don't have time limits on each lift. You explained the velocity and time limit stuff. Yeah, I don't see it. Yeah, and that's the move into and I'm sorry, moving inside and out of the car is same with gate. Same. Yes, walking. Absolutely the same.

The lateral at the elbow would be like medial knee pain. Yes.

Thank you, that's actually very helpful.

Yeah.

Yeah, right.

Gotcha. That's helpful. Do you see the difference? I will probably have a follow up at some point, but that gets me going.

It's starting to IR. Yes. As you descend, the internal rotation is increasing from the bottom up.

I mean, is that what we're

and you'll orient to.

Awesome. Perfect. OK. My center of gravity passes over the foot. So I have a reduction in this IR representation, but it's coming up from the ground, so it's going to be ER from the bottom up. So as I reach the later stages where the foot's still on the ground, still pushing in the ground to some degree, but I'm increasing the ER representation, I got the ER that comes up into the pelvis. So if you're going up into the pelvis, what does that answer outlet look like now?
