Good morning. Happy Monday. I have no coffee in hand and it is perfect. All right, a very busy Monday coming up. So we're going to dive straight into today's Q&A. This question is with Matt, and Matt brings up a great question in regards to how we produce energy, fatigue, and its influence on relative motion. There's a sweet spot where relative motion truly exists, and we tend to associate it with tidal breathing because what we're able to do is actually meet energetic needs very easily under these circumstances, so we don't see a massive recruitment of musculature that would interfere. Now let's superimpose the concept of fatigue onto things. We produce a higher level of fatigue, which means we become more reliant on anaerobic energy sources, increasing the recruitment of certain musculature in the axial skeleton and superficially. Now we start to get interference with relative motions because we have to recruit larger motor units and more forceful motor units, which requires us to reduce our relative motions. There's a very strong relationship here. The thing you want to take away is that everything just tends to be the same. If we can produce energy efficiently and effectively, and offset fatigue, we tend to maintain relative motion for a longer period. This is a great question and gives you a reason to understand how we produce energy and what those influences are depending on how we're doing so. Again, short-term energy systems are going to be more reliant on those high-force motor units. If we can produce energy more efficiently, with a bias towards oxidative energy production, we're probably going to be able to maintain relative motion for a long period of time. Thank you, Matt. Great question to lead off the week. Everybody have an outstanding Monday, and I'll see you tomorrow.

Yeah. Lower foot, right? So she's in that middle space pushing up to try to save her life, so to speak, right?

OK, so I take all of the relative motion out of the towel. I twist it as hard as I can. All right, you ready? And then I twist it harder and it bends. That's what you're seeing in his back. Now, do you see my hand change its orientation? As I twist it, you see my hand move. You see it? See that? And I changed the orientation of my hand relative to the towel. No. The towel bent and it changes the orientation of my pelvis. So it looks like my pelvis changed direction. It looks like my hand changed direction. Not pelvis. I'm thinking about this squat guy. Do you see that I have not changed my relative position of my hand to the spine, but the spine bent. And so it looks like my hand moved up like that. It's just following the bed. It's like, if I do that, there's the orientation of my hand, but there's the bend in the spine. You see it?

Is that it?

It was IFast year. Yeah.

I've seen your feet.

There are a few things that are referred to in that area, but let me give you a little hint to provide some guidance. So if you draw a line straight through the axial skeleton, starting from the back of T4 and go straight through T4 and out the chest, do you know where that line goes out the chest?

Early Nemo, is that what you said?

Okay. Shorter by the traditional representation of a muscle getting shorter. If we use the biceps as the example, that's the shortened representation.

Yeah. So that's why it's like when you're in a pickle and you can't make the change, it's like that's when you got to lay hands and you've got to have the tool in the toolbox. It's like you address that, you reduce the concentration, you take the demand on the bony structure away. And then they tend to feel a lot better. Don't forget that the bones are covered with connective tissues, like the periosteum, okay? Very sensitive. Do you dry needle? Yeah, I do. Okay. Did you ever go too deep on somebody's glute meat? You need the really big needles for that one. No, you poke them in the ilium and they, like their vertical jump increases by 12 and a half inches. It's really sensitive. So if you can take pressure off of the skeleton, they tend to feel a whole lot better.

Do they ask questions like, what is that in the sky?

Sorry about that.

That is correct, sir. Don't be distracted by the sharp shiny objects. Everybody looks at the bony position and they go, no, my arm's moving this way. It's like, no, that's the direction of movement.

Right. And then when you are catching something, like the representation I showed you the other day, you're still getting some of that, but because of the load, you don't have that relative motion. You have it, but you're kind of just orienting inward all of it, the whole, the femur and the tibia.

I understand. I understand. Just like the ankle motion when we jump, just I can extend and just the stretch and. Right. Yeah.

So you're going to promote the expansive strategy that you want to create the delay by going up, right? So we put you on a front foot elevated split squat because that's going up the stairs, isn't it? It's like when you step up onto a step, you're promoting the delay, aren't you?

OK. And it wasn't with an IR substitution of orientation.

Right, but I understand that you have relative positions that are, so I have to have these twists and compressions that are like literally like a spring, all right, that are going to absorb that force because if this is the foot and this is the proximal hip, like the big picture is I'm going to have these twists that are going to compress, I'm going to come up over top of it and then it's going to untwist in the other direction as I go over the foot. Does that make sense?

And then as you go down, it's going to square up towards the front because you're moving more into an IR representation under that circumstance. Right.

Correct. Yeah. So, when you think about the anterior orientation. Okay. So let's just look at the pelvis for a sec. You've got five segments in the lumbar spine. Fair? Yeah. Okay. It doesn't all orient to the same degree at the same time. It's sequential. So if we're a wide ISA with anti-orientation, it goes pelvis, L5, L4, L3, L2, L1 in that sequence. The greater the degree of compression, the greater the degree of anti-orientation, the sequential loss of spine motion will occur as well. So when you have somebody that has like one of those magnified measures, it's like 45 degrees of hip IR. Okay, that's a lot, right? That's somebody that still has a spine that can move in some of those segments. When you have the reduction of both ER and IR, which is a lot of anterior, posterior compression, a lot of anti-orientation, all of that spine motion starts to disappear. This is where you get the people that come in and you measure them and they're like 20, 10, like 20 ER, 10 IR kind of thing. Do you understand?

Oh, OK.

There you go. That's where I wanted you to go. That's what I wanted you to say. Yes. We have to get her back there. It's like where she would start would depend on what she can capture with her foot. You were absolutely right all the way through. It just took you a second to get to that middle representation. So, Michelle, the answer is you've got to get the foot contacts on the right side. You have to find a position that you can actually get the first met head down on the big toe side of your foot. That might mean having to put your right foot slightly forward at first in a stagger, and then slowly bringing it back to where it's slightly behind the left, where you can push it down into the ground and push off of it. Does that make sense?

It's spinal IR, not hip IR. That's why I say internal rotation strategy, because if I say internal rotation, you might assume that I'm talking about the hip. It's like the hip is not creating it. He's pushing into the ground, but he's got to, like, if I do this with my shoulder, we call it a shrug in the shoulder. We call it a hike in the hip. I'm not sure why, but that's how we do it. And so this is my cervical spine internally rotating. So it's going down and forward on the left side to create that position. That's what he's doing in the squat. So he creates ER. He's got IR. So he still has a little bit of IR in the hip and pelvis. And then you put more and more weight on it. And it's like, oh, there's less ER space. Now I got to twist my spine to create the IR. So it's just a progressive increase in the compensatory strategy to produce the internal rotation.

So I'm wondering how a distal joint position affects the ability of the axial skeleton to gain inhalation, for example. And I think it might be a relatively foundational question. But if you, for example, if you have a twisted elbow position, if you don't un-que it, does that prevent you sometimes from acquiring the ER, the IR that you need for pronation?

Yeah.

Okay, so the premise is useful when you're trying to hang onto some internal rotation. Now here's the thing you're going to have to be careful of. Because of the population that you work with, you got to be careful that you're not creating an anti-orientation under those circumstances. Because if you give up foot contacts—like if you give up the lateral foot contacts—then you're not going to be emphasizing relative movement; you're going to create an orientation. From a parallel standpoint, it might not be too bad because you are reinforcing some elements that you would use to pick up heavy things. If the goal is relative motion, which is what it sounds like, then you've got to be aware of how you're pushing through the ground. Because you are pushing through the ground while dragging some weight, I would expect that you would have a fairly strong medial foot contact.

I did not.

You should have guessed the opposite direction, brother. Think about this. Are you inducing the turn?

No.

Okay. Easier to capture.
