Yes.

You would have a combination of factors. So, for example, if you have somebody who's a funnel shape, like they have that upward bias but with varus, that would—if they had that yielding capacity—make them a really good squat jerk performer. You know, because you can drop down really fast but still have the funnel shape to stand up with it.

Yes. Yes.

So in this sense, what you said when you have a wide and you would try to bring them back, would you, if I refer to the foot position, would you keep it more in the medial propulsion, more than not in such a negative tibial angle as you would keep a narrow?

Okay.

So joy is to get you to recognize the importance of this moment. That's a really strong emotion. And then everything else in between is peace and happiness. But the strong emotions are just attention-getters. That's it. And then you decide. Then you decide, okay, where's the value in this? And again, life or death situation, you better be angry. Like to the nth degree and then use it to your full capabilities. But other than that, words don't threaten me. You could try to your heart's content to insult me right now. Listen to me. You can try to insult me. It's impossible. I allow myself to be insulted because that's my choice. But if I don't allow that, you can't insult me. You can't hurt my feelings unless I let you. And people don't recognize that fact. They think that, well, this is how it should be. They watch movies and they say, oh, this is normal behavior. It's like, no, it's not.

Yeah, it does.

Yes, it's just, I don't know, conceptualizing it is definitely a roadblock sometimes for me.

Get it? Yeah, I do. I do. Yeah. So it's sneaky. But if you understand what the possibilities are, then it helps you get out your chest boards, right? Okay. Yeah. As I say, all measurements are dirty, which means that the whole body is represented in each of your measures, so let me give you another for instance. So when you look at the shoulder internal rotation measure on the left side, right, which you got a pretty decent measure there compared to what your left hip was representing, right? So the left hip IR is only like five and you get 60 IR on the shoulder and you go, what the heck's going on there? Well, if you're laying on the table and you're twisted this way, guess what? My neck is turning this way, right? My lower cervical spine is going this way. That's going to magnify your internal rotation measurement of your shoulder because you're not measuring just shoulder motion. You're measuring internal rotation. Right. And so if that spine's turning away, that magnifies your internal rotation. So that's how you identify these things.

So one isn't great for force production, but one is also great for speed versus the other one, right? Because it takes time for the deformation to occur. One deforms faster, so as it releases its energy, it does so at a higher rate. For instance, which one would you prefer to be snapped in the arm with—someone pulling back a basketball and releasing it, or the balloon? The one that snaps you fastest is the one that will hurt. Again, that's where yielding comes into play. This is why there's concern about secondary consequences in training. We can trace this back to the beginning of the call where we discussed distribution of resources. The question is: how stiff do we want this tissue to be? What's the optimum stiffness? For high-force production, it may be beneficial to be more stiff. For high-velocity production, it may be beneficial to be less stiff because we need the tissue to deform at a higher rate—that's what speed is. So the balloon represents a more yielding action, while the basketball represents a more stiff or overcoming action.

Yeah.

Middle. If I put you in the left sideline, what should you have on the left side? I should have middle on the left side, shouldn't I? I have to be able to approach it. So that means I have to have a superimposition of internal rotation on the left side to even put you in left sideline to be successful. Exceptions to the rule, certainly. If I got somebody that's pointy and I need to go manual on somebody, I might put them there. But generally speaking, to do an activity, an intervention on the left side where they're actively participating, I would need to have some internal rotation on that side.

So is rounding in the thoracic spine, like having that hump versus lower backgrounding, is one person later than the other in either of those two cases?

Well, that's exactly what we just talked about. So that's the yield, right? So the yield is post-year expansion. Well, how do you create, post your expansion of discs? Well, you have to have compression on the opposite side.

Yes.

Okay, how can that possibly be if I have a concentric orientation of the anterior outlet?

For example, the down leg and then you're just using the right leg to move back and forth.

And another question. This is something that I also have some trouble with. If you're initiating a roll with a lower extremity, and your leg is relatively straight—so you're just doing it, let's say, going from right to left. In your video on rolling, you said that you're going to have a yielding strategy on the right side. Correct. Which is confusing to me because the right side is moving forward, the left side is staying back.

Not only does this reduce power output, but it's going to slow me down. And so we have to attend to this anti-orientation. Good morning. Happy Tuesday. I have neuro-coffee in hand, and it is perfect. All right. Man, busy Tuesday. Got to dig straight into today's Q&A, which is dealing with the influence of an anterior-oriented pelvis on change of direction. And so I'm going to show you a clip that's associated with how this influences a baseball pitcher's ability to change direction as they push off the rubber. But we can also apply this to any athlete that has to perform some form change of direction. So if we had a soccer player, a court sport player of any kind, where they have to do some cutting, this is going to be a similar influence. And this is in regards to the influence of an anti-orientation. So remember, the way we're going to identify anti-orientation is the entire pelvis is moving as a unit into its anti-orientation. This is to create an IR force downward into the ground, but we're also going to sacrifice external rotation, ranges of motion in the hip. The other byproduct of this, and this is the part that's probably a bigger influence, is that I'm going to move the center of gravity forward very, very quickly. So if we were looking at a foot, remember as I get this ankle rocker element, as I'm pushing force down into the ground, this is my IR force into the ground, if I anteriorly orient the pelvis above the foot, what I'm going to see is I'm going to see this tibia translate very, very quickly. So what's going to happen, I'm going to move towards max P very, very quickly, and I'm going to lose my heel contact. My center of gravity is going to be moving forward really quickly over the foot. As far as a sprinter, I wouldn't be so concerned about this because they're going to try to translate themselves forward in this direction. But if I'm going to change direction, which is perpendicular to this orientation of the foot, what's going to happen is I'm translating so quickly in one direction that I have to create a delay strategy by lifting up the heel, moving towards ER. So I'm going to go upwards first. I'm literally going to be lifting my center of gravity up to slow down in that forward direction before I change direction. And then we get this little hop off of the forefoot as I'm sort of pivoting off of that forefoot. So not only does this reduce power output but it's going to slow me down and so we have to attend to this anti-orientation. So from a strategy standpoint there's any number of ways that we're going to be able to posteriorly orient this pelvis.

Get it?

I gotcha. How would, yeah, that's gonna be a conundrum. So it's not worth pushing at this point. I can see how balancing like what they're coming in for—just pain alleviation—with what your preconceived, okay, gaining relative motions, like that internal battle would definitely be, I feel like that would be a struggle, especially early on, for someone like me who's learned from your model as much as I can online instead of imposing my ideas on that person, just giving them what they want, but also needing to understand the consequences of what I'm doing. You got a new point.

Okay.

You did that exercise. Would I get some sort of benefit out of that from a yielding capability?

Yeah. Go ahead.

Everything we've demonstrated shows that if we didn't have the connective tissue behaviors, we would not be able to do anything. We'd be like boneless chickens.

I don't doubt you for that. I don't doubt you.

Sounds like fun.

Yeah, that makes sense. When you were talking about relative motions, this brought up another question that I've had. Why increasing relative motions seems to decrease force production and vice versa. I'm having a hard time understanding why that would be.

Okay, so let's be very clear on what the goal is. So is the goal to acquire best depth, which would be the early representation of the pelvis and the deep squat? Is that correct?

The whole thing would just orient over the best.
