Well, if we look at it as just a change in shape. So as I twist a hip.

Yeah.

Yeah.

Cool.

Good morning. Happy Tuesday. I have neuro coffee in hand and it is perfect. All right. Digging into a very busy Tuesday. Just wrapped the Intensive 16 over the weekend. That was fun. Great group of people had a great time. Intensive 17 prep starts today. So we're rolling right into the next one. So again, very, very busy. So we're going to dig straight into today's Q&A. This was Christian's question about improving balance and preventing falls in an older population. The number one reason for this is we have to restore power output. We talk about how we do that. The cool thing about this is that the principle holds regardless of population in regards to power output. We just have to look at it in context and within the individual's capabilities. So whether we're working with high-level athletes or the older population, we approach this from the same principled standpoint. We're just going to be developing power output in a different context and for different reasons. Christian, this is a very helpful question for many students coming out of school. If you know a student working in extended care facilities with older populations or if you have older clientele in your fitness training facility, you'll find this question very useful. Again, thank you Christian. If you would like to participate in a 15-minute consultation, please go to askbillhartman@gmail.com, put '15 minute consultation' in the subject line so I don't delete it. We will arrange that at our mutual convenience. Don't forget to include your question in the email. Everybody have an outstanding Tuesday and I will see you tomorrow.

He can only turn his leg out so far before he runs out of strategy here.

Okay, would you have a nutated sacrum?

Okay, but if it's not.

One of the easiest ways to see this is to start directly on your side. So let's say that you could be perfectly positioned on your side, which is virtually impossible. But let's just say for the sake of argument. You're on your right side, so your body mass is going to push down into the ground because gravity works, and it's going to compress you front to back. So right away, the people that we talk about that have a lot of superficial muscle activity and get compressed front to back immediately gain expansion anterior to posterior by putting somebody on their side. And we know this; there's literature that supports all of this. Then gravity pushes down, which gives us a mushy spot on the ground, and that allows us to promote shape change. What we have to decide is what shape change we want. So let's say that we were trying to move somebody into a late propulsive strategy. A late propulsive strategy would be an externally rotated representation with superimposition of internal rotation that goes from the top down. This is like somebody that's pushing off the ground. If you're standing on your left foot, you'd be in middle propulsion. If you step forward with your right foot, the left foot would be in a late propulsive representation. So that's what we're trying to promote. If we're trying to do that from this ideal sideline representation, I would want to lead with the upper body because the top-down mechanics will be represented. So this would be moving into an external rotation representation with internal rotation superimposed from the top down. So again, it matches the mechanical representation of an element of propulsion. So that's the shape we want. We want a little more compression on the backside, a little more expansion on the front side, and this is what allows us to move forward. So that's step one. That's your upper body rolling behavior. Now let's go back to this perfect imagined sideline representation. Now let's say that I'm trying to create a delayed representation. This would be if you're standing on both feet, you took a step forward with your left foot and landed on your left foot. So now the forces are actually coming up from the ground into the body. So I need to absorb that internal rotation and I need to have an expansive externally rotated representation to superimpose that internal rotation on. Internal and external rotation are always superimposed until they become the same thing, but that's a different story. So we're now creating a delay strategy. Here's the cool thing. When I was laying on my right side and I initiated that late representation with the left side of my body, the right side was actually in a delay strategy. So right away I've got a delay and a late strategy. But for consistency purposes, if I'm trying to emphasize a delay strategy on the left side, I'm going to initiate that with the lower body because again, that represents the internally rotated mechanics coming from the lower part of the body upward. So again, the mechanics would match. So now I can roll in both directions, but I might have to roll differently. I might have to initiate it differently. If I split the body down into right and left halves, and I say I always want a late strategy on this side and an early strategy on this side, now I know how to initiate my rolls. That allows the client to understand: you get to roll in both directions, that's fine. But when you roll this way, I want you to do the upper body lead. When you roll this way, I want you to do the lower body lead. That's why there's no interference with the intended outcome, because most problems arise because we create our own interference. If we don't understand the mechanical influences that are going into a movement, we tend to do a lot of things that we just get in our own way. So again, this is a great way for us to understand how to not do that. It's just a matter of understanding a little bit about the shape change, a little bit about the propulsive behaviors, and then matching the activities to those behaviors.

So your body position when you're doing your slide push is very similar to an accelerated position. But the magnitude and the duration are a little bit different. Locations may be very, very similar. And so then it becomes very, very useful.

I was wrong. Uh, so is she ER and then just oriented?

Yeah.

Okay.

Yeah, it's simple enough that makes total sense.

There are seven of them and they're all there at the same time to different degrees and different relative importance. Rate is the easiest one to see and discuss, because all I gotta do is pull out my silly putty and you can see the difference in the two.

Not big, but if it is, you don't know until you try. Yes.

Their structure is already going to determine the tibial angle.

So would you say that someone with the varus presentation of the knee is pushed more forward than the one with the valgus?

Any strategy?

Yeah.

Well, you have an anterior orientation, for sure, based on your measures, right? So your HIPPR measures give you that piece of information. So you know that you're forward. The lack of IR, the limited straight leg raise, again, that's a push forward. So you're moving towards a later representation of propulsion. So you're farther forward. You're trying to get past middle, trying to get into a late representation there. That's what this is.

So if you're a bodybuilder, would it? So you ever seen a Mr. Olympia with a 42 inch waist? A 42 inch waist. Yes sir, like 42 inches in circumference, like a big wide waist, big wide hip on an Olympia. Have you seen one? No. Why not? Because it's not pretty. It's not pretty. Right bodybuilding is a beauty contest, right essentially, and there are certain things that are aesthetically pleasing to the eye, right that are more representative of success in that environment. Power lifters would benefit more from a different structure. Right, so they look different and therefore they produce pressure in a different manner. I would also argue that when you get up into the higher classes of power lifters, they are equally as muscular as bodybuilders are but their physical structure is less pleasant. They're carrying a ton of muscle. They also might have a ton of body fat that goes with them because there's a benefit to that. So we can go right back to putting more stuff into a muscle creates more pressure. Well, guess what? If I jam more stuff into your belly, into abdominal body fat, I can compress that and it makes me more rigid and it allows me to lift heavier weights. Right? So again, multi-factorial process, but we're also dealing with structure. So under certain circumstances, if I had a thorax and a pelvis that were about the same width, so I'm built kind of like a refrigerator, it would be easier for me to stack weight on that than if I had a funnel that was sitting on top of a tiny little pelvis. Right? Now, if you go back and you watch the old Ronnie Coleman videos, he had the ability to sort of change shape a little bit under some heavier loads, right? So you watch him do the, you know, the 800 pounds squat. Have you ever seen that?

Sorry. That's not the thing. No problem. into consideration when loading. Is it going to be the same thing? Is it going to be creating a situation that I don't want if I do that on both sides? Did I have one side that's like an EQI, like an asymmetric, almost an EQI? Would that be a better fit for one side or the other? I'm just trying to figure out best way to load.

Is it normal for elite runners and sprinters to have barely any adduction? I mean, they'll have it because of the anterior tilt, if I, you know, if I bring their knees up, they'll have it at a certain degree.

And that's a different curvature than like with the whole back rounding compared to somebody that has just lower back or lumbar rounding that's not an accomplished expansion there that's you know gross flexion. Right. And so I guess my question is if you have to choose which one is worse in terms of how much relative motion they lack.

Does that make sense?

That's really helpful.

OK, how does it get there?

Yeah.

Okay, so if you're just in supine and you're reaching with the right leg across your body and the pelvis hasn't started to move yet.
