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.

Where are you? What do you mean?

So you would compensate in the lumbar spine most likely first because it's the easiest access, right? But again, it's like, so if I keep going forward, then the pelvis and the lumbar spine become a single segment too. Okay, because you have more muscle activity that is trying to keep you forward. And so then the only way that you're going to create the ER space under those circumstances is to actually create a bend in the axial skeleton, which is not expansion. It's just a bend, right? So that would be a later representation where you're essentially losing all of your segmental motion there. And you just like literally it's the, you know, just take any tube and, you know, bend it. That's what basically would be happening. And that's why the posterior structures then become compromised because they have to elongate. It's not this nice distributed thing. So just take like a string from the base of your head to the sacrum, right? they will try to elongate that string. Like literally that's where the lengthening would have to occur, but it's not like this nice AP expansion that you would associate with the volume change. There's no volume change in it, it's just a bend.

And in that case, how likely are you to speed up the healing process of herniation? If you create a nice heal that the posterior superficial musculature.

You're going to have, they're going to get pushed forward on the left first. So this is your left limited straight leg raise. This is your inability to capture an early propulsive representation. Then you got to say, okay, they're most likely going to be forward on the left, but they go forward and then to the right as well. Good morning. Happy Tuesday. I have no coffee in hand and it is perfect. Okay. A busy Tuesday. As usual, we're going to dig right into today's Q&A. And this is with Pradesh. And Pradesh works with throwers, more specifically cricket bowlers, but this is going to apply to just about any throwing athlete. Whether we're talking about baseball pitchers, we do mention Javelin in this discussion as well because of the similarities between Javelin and cricket bowling. But essentially what Pradesh is just dealing with is his throwers are presenting in a late propulsive representation, which means that they're not truly capturing any representation of middle propulsion. Therefore, they're having to use compensatory strategies to drive force downward into the ground as a substitution for their internal rotation. One of the common findings you're going to find here is the limited straight leg raise as a KPI. That's going to be indicative of that thrower that is pushed more forward towards that late propulsive representation. The concern here is twofold. Number one, we're going to have a reduction in force application into the ground. So that's a performance related issue. But from an injury standpoint, what we're going to see is we're going to see these prolonged phases of ER. So the inability to capture the early propulsive representation where we're starting to superimpose internal rotation is either delayed or nonexistent and so we're gonna end up with prolonged ER phases and this is we're gonna see a potential medial elbow stress. And again, I think this is going to be useful for a lot of folks and we talk about some solutions as well to recapture that early propulsive representation. So I hope you find this useful. If you would like to participate in a 15-minute consultation, please go to askbillhartmanedgmail.com, askbillhartmanedgmail.com, put 15-minute consultation in the subject line, so I don't delete it. We will arrange that at our mutual convenience. Everybody have an outstanding Tuesday, and I will see you tomorrow.

So I see why the eccentric, why it needs to go eccentric orientation in the left anterior outlet, but why does the right anterior outlet also need to be eccentrically oriented?

And that's the same thing that we're kind of talking about here. It's like, so by fixing that foot to the wall, you're kind of sticking in towards a middle representation. And then I move you back into a late representation and an early representation back and forth by doing the stepping activity. So just stepping forward and back on sideline.

Okay, start on your side.

Like at the rubber, they sort of like lighten, or you're talking about at least.

So always remember that you're measuring in reference to the table. It's like the arm really doesn't weigh as much as the leg does. So if you had like a big, gigantic arm on one side and a normal sized arm on the other side, chances are you try to internally rotate it with a big, giant arm. It wouldn't have turned the spine nearly as much. And so you would have a measurement that would be more representative of a limitation. So again, it's like what's moving as you perform these measures. When you bring the leg up over the hip and it pushes the hip into the table, you'll get a true representation of the limitation of internal rotation. The arm being lighter, everything just kind of turns with it. That's how you got to discern these things. Whenever you're measuring a limb, you're measuring the entire body moving. If the question is how much does the hip move? How much does one side of the pelvis move? How much does the spine move as you're performing these measures? That's how we figure this stuff out.

All the herniated disc is a focal delay strategy. You want a distributed delay strategy. So no tissue is under its maximum load where it's not this focal stress. If it's distributed, that's how you do everything.

Yes.

So here's what you have: some people, when you ask them to jump or land, land in a late foot position where they're just on the ball of their foot with their heels up. The yield occurs at the first metatarsophalangeal joint. If that's what you want, then you've got it. If you want the yield distributed elsewhere—like in a middle propulsive representation—you may want to capture that middle propulsive representation first and then apply an activity that produces yielding in that position. This is because muscle activity can restrict your ability to access a position. That might be where you need to start versus trying to produce a randomly applied yielding action. For example, if you drop a medicine ball and say 'catch it and absorb it,' they'll yield. But the question is how and where? Do you want the yield in the medial knee? We've all seen people who jump off a box and their knees slam together when landing. Again, that's a yield—but is it where you want it? So acquiring the position may be the first step to ensure yielding actions occur where you want them to be.

Cool. Thank you, Bill.

And that is predominantly done through your connective tissues. Muscles are just tuning.

No, yeah, okay.

Generally speaking, yes. I mean, yes, it's turning. Sure.

It makes sense. But see, okay, so what direction do the forces go? If you're not locked into a single piece, what direction do they go? Do they go up into the bar or do they go all different directions like the exploding car? Yeah, you see? So again, it's like you have to direct the force to produce the outcome that you want, right? There's no way to do it if you don't lock everything into one piece.

Yeah.

Right. Okay. So, what I need to do then is move you back on the same axis that they got here. So I need to do that. Okay. Right. Which is why right foot lead kind of activities on those oblique people is I'm going to push you back into the left.

Yeah.

It's higher force. Yes, yes, yes. But yeah, I like how you, yeah, okay.

Right? It's like being in a car accident. You ever been in a car accident?

Okay. So based on my current understanding, there are no levers in the body because bones don't touch under normal circumstances. Yes. And so when bones do touch bad things tend to happen. So given that information, I'm looking to specifically visualize, because sometimes I have a hard time visualizing things even though conceptually maybe they come a bit more easily. So for something like the lat or the pec, a lot of people who are in this hypertrophy world where we're looking to take origin to insertion, line of pull, we're trying to manipulate all those things, axes of rotation. How does the model sort of fit into hypertrophy? And I know you've discussed hypertrophy on sort of the level of your model before, but for something like a single arm lat pull down or just anything with the pecs, those two muscles really, from a visual perspective, look like they're using the rib cage as leverage and I've heard a lot of people say that the rib cage serves as a fulcrum to that sort of rotation. So I was wondering from the perspective of your model how you conceptualize that with fluid movement, because with the rib cage it's a little bit trickier for me to visualize it rather than talking about something like a knee.

Gotcha.

Does that make sense?

Have a great day.

And then if I pull the knee forward, I'm going to start in a more right oriented position. So I'm not going to hit that mutated position as much when I go down because I'm starting in a more churned position.

Four things. That's it. And it's not four concepts. You have four things that you'll be able to make use of in that time frame. Because number one, it's like you have to pay attention to what you have to appreciate people's attention span. They're not going to be able to walk away with an overwhelm of all this information.

Yeah, yeah. So it's very simple when you look at it that way, you go, oh, well, that makes total sense now, right? And then you've got any number of variations on a theme as to what you can do in regards to the movement velocity, load. I can throw my offsets on there so I can capture a lot of things and manipulate this one activity in many different ways to accomplish many different tasks. And I can create these little micro progressions where, yeah, it's the same activity, but today it's just going to be a little bit harder than it was last time. So I have a joint lever question and I'm going to give away some free stuff. Good morning. Happy Friday. I have no coffee in hand and it is perfect. Man, hadn't had this in a week. Truly missed it. That's a good batch, Dr. Mike. Way to go. So Friday, just got back from vacation. Need a massive catch up day. The one drawback from going on vacation is the accumulation of stuff while you're gone. So the Q&A email box is full. And we'll get to those things as we can over the next week or so. I do have some housekeeping stuff and then we'll get to a joint lever question here in just a second. While I was on vacation, I thought, well, how's another way that we could take this transaction thing off the table and help some more people? And so here's what we're going to do. So pay attention. I'm going to do a series of free 15 minute consultations. So here's what you're going to have to do. You've got to go to the Ask Bill Hartman at gmail.com email. In the subject line, put free 15 minute consultation request. If you put anything else in the subject line, I will delete it. Free 15-minute consultation request. So here's how it's going to work. You get to ask me anything that you want in that 15 minutes. We're going to record the whole thing on Zoom because chances are, if you've got a specific question, someone else does too. So we'll be able to help other people with this. At the end of the week or so, when we get around to the Coffee and Coaches Conference call on Thursday mornings, I'm going to have those fine folks do a little bit of voting and they'll vote on the best question of the week. And if you get picked as the best question person, here you go. You get the t-shirt hoodie, and one of those, you get a hat too. So a little incentive, I don't know how big an incentive that is. For some, maybe a lot. For some, maybe very little. Doesn't really matter to me. This is what we're going to do. So like I said, we'll be able to help a lot of other people and we'll be able to get your questions answered as well. So again, one more time, subject line, free 15 minute consultation request at askbillhartman@gmail.com. Okay. So let's dig into a little bit of a Q&A question to wrap up the week for you guys leading into a great weekend. And this comes from Patrick. And Patrick says, hi, Bill. Hi, Patrick. He goes, is looking at joint levers totally, is looking at joints as levers totally useless? And I would say, Patrick, that I don't look at joints as levers for various reasons that we'll get into, but there may be some use in some of this two-dimensional representation that we typically use by Euclidean geometry. So they break things into the imaginary planes, and they try to calculate forces, and they look at joints as levers. There may be some good reasoning for that, because what it does allow us to do is potentially identify where we might be seeing loads or stressors being applied in certain aspects of movement, which might be helpful to determine causation of damage, pain, injuries, however you want to look at this thing. But from the reality standpoint, the reason that I don't like to look at joints as levers is because we need one specific thing for a lever system and that is a fulcrum. To quote Archimedes, it's like give me a lever long enough and a fulcrum on which to place it, and I shall move the world. So without the fulcrum, you don't really have a good lever system. The problem with the fulcrum in a joint is that we have friction and we have heat. And both of those are going to be destructive to the hyaline cartilage at the ends of the bones. As durable as it may seem, it is still delicate in regards to its ability to wear away. The other aspect of it that we haven't talked about, I don't think before, is that this friction would actually slow down joint movement, which would make movement very, very difficult. So if we think about normal walking, the hip joint's going to move at about 200 degrees per second. If we look at throwing a baseball, it's about 7,000 to 9,000 degrees per second. And so if you want to get an idea how fast that is, swing your arm around in a circle 20 times in one second, and that's how fast Major League baseball pitchers' arm is moving. And so if we did have joint levers and we did have fulcrums and we did have that friction, I don't think we'd be able to produce these movements. And they would be incredibly destructive all at the same time. So rather than me digging deeper into this, what I'm going to do is I'm going to cut away. We're going to go to a video that I did previously where I was talking about why bones don't touch and why the joints aren't levers. Because I think it would be a good video for you to reference Patrick. So for the rest of you, have a great weekend. Have a terrific Friday. I will see you guys next week. We'll be digging into some Q&As and hopefully we'll get a few of these free 15 minute Zoom calls scheduled over the weekend. And we'll present some of those for you next week. Everybody have a great weekend. I'll see you later.
