Understood, but okay. They are applying force against the resistance. Okay. So what is required to increase a synovial joint's ability to move? Is it muscle orientation or connective tissue behavior?

Right, so what would happen if you did create an extensive delay strategy and you're trying to sprint?

No, I haven't.

Yes. Get one. Because everything you just said, everything you just said will be in that text. Like, there's a lot of stuff like that.

That is what I don't know. Answer my question.

I mean, you'd lose the race.

Okay, so let me talk about what scuba diving is for a second. And again, you'll be able to picture this, okay. So when you go scuba diving, you have to put weight on you to push you down underwater, but once you get underwater a certain depth, there's enough force above you that will push you down. Like you will accelerate into the ocean floor if you allow it to happen. So you have to wear what's called a buoyancy compensator. It's actually like a life vest that you fill up with air to create a balance between the forces that are pushing you down. Then you get enough expansion to hold you up. So you want to try to get what's called neutral buoyancy. So literally you put enough air in the buoyancy compensator to balance the force, and you literally sit at the same place in the water. So you don't sink and you don't go up. But if you sit still and you take a breath in, you go up, and when you exhale, you go down. So you have this little excursion as you breathe in and out. One, if you have some frame of reference, you can actually see yourself going up and down, and you can feel yourself going up and down. So it's a great little representation of this concept. So you take the same thing—it's like, okay, this is a fluid-based kind of representation, but guess what? On Earth, this exact same thing is happening to you as you breathe. We don't feel it as much because we're so grounded by this perception of gravity. So the ground is pushing up against you constantly, and so you feel this sense of acceleration, of perceived gravity. So you don't feel the up and down, but the reality is that as you breathe in, your density is reduced, you go up, and as you breathe out, your density increases and you go down. That's why I always describe ERS as up and IRS as down, is because that's what's happening. But it's based on the behavior of how these helices change the physical shape of the cylinder, and you, sir, are the cylinder.

Like, on a timeline.

Okay. So that's the question.

Well, without question, right?

Gotcha. So is the resultant force of going up with extra rotation, is that more based on just fluid dynamics or is that some other physical property that I'm not appreciating?

There's a lot of good prone mobilizations that work really, really well in regards to what you're describing. Is that in the Greenmans manual textbook? Yes. Usually, I spent a long time since I looked at Greenmans, but that's a pretty good place to start. And again, I don't know how many I've got. I've got a few. But those techniques are useful because, again, all you're doing is you're promoting the shape changes, but you're using the relationships just like we're talking about. It's like you apply pressure to the posterior rib cage. You're going to promote a compressive strategy. You're going to get the response of expansion elsewhere. That's going to promote the turn that you're seeking, which will potentially reduce the concentric orientation that's promoting the turn in the first place. They work quite well. They're not the solution, but they will buy you space to work in, for sure.

Yeah.

Yeah.

Well, you have mass per unit area. Because of the expansion, your mass per unit area changes. So that's going to alter some influences. The physical shape change. So you get a little bit bigger. So you're going to go up. So it's the wacky wavy tube guy. So the wacky wavy tube guy stands up when you fill them up with air. That's you. I mean, you have to follow the same principles. So it's really no different. You take the air out of the wacky wavy tube guy, he goes down.

Okay. That's really helpful. Yeah. As far as the thoracic spine goes, I mean, I understand how if you lie someone on their side, you can get AP expansion, but from like, I mean, there's not that much force directly going into the vertebrae, I would assume to directly induce a shape change. Like you would with the pelvis, like you get the direct pressure on it.

Awesome. So we're basically talking about static stretching, right?

Yeah, so you're trying to minimize that because your ground contact time is like super fast when you're sprinting.

You see it? Yeah.

Really?

I don't understand how we got there.

Right.

We can't ignore the rules. The rules exist. We just have to recognize as a human being based on what structural elements that I bring to the table, it's like, how do I behave within the rules? That's all I'm trying to do is create a coherent representation of what's actually happening as we move through space. Because again, it's like, I can't change the rules. And thankfully, there's very few rules, right?

Like you would with the pelvis, like you get the direct pressure on it.

Okay, so you're at the bottom of a fly?

But there still has to be one. There still has to be one.

No, actually, I would love that point. I love when you said, but talking to Paul, looking at all systems, like, because they all work to an extent, but they have a limit. And then you look at- We're all looking at the same thing.

Yeah.

Yes.

Which would literally be probably an effect of the footing ground or that occurred in the different phases of sprinting.
