Muscle Imbalances for Athleticism

I have a few more clips for you when it comes to Assessment & Exercise (“Advance Screening” starts next Tuesday).

These clips are from Anthony Mychal‘s presentation – Assessment & Exercise for Athleticism.

With this first clip, Anthony has a new way of looking at Da Vinci’s Vitruvian man. I won’t look at it the same again.  Very cool observation.

What Can We Learn from Da Vinci’s Vitruvian Man?

If you are unable to watch or listen to the video above, check out the transcription below.

So this is just a diagram of Da Vinci’s, one of Da Vinci’s work just to illustrate this. But if you start here at the hip, the hip houses the biggest muscle. So if you go in circles, concentric circles from about that point, the further away you get the weaker the muscles are going to get. And as you go the smaller they get, too. So the size, the natural size kind of hints at the natural strength. So the muscles of the hips should be stronger than the muscles of the quadriceps and hamstrings and those muscles should be stronger than the muscles of the calf and those will be stronger than the muscles of the foot and the same holds true for the upper body. So that’s in general the legs are bigger than the arms, too, if you want to compare that and the legs are stronger than the arms and with the hands and feet being the last link in the chain. But that’s just to illustrate that the further away you get from the powerhouse, the largest muscles in the body, the weaker the muscles get.

In the second clip, Anthony talks about dynamic correspondence. It is an advanced concept that will get you thinking if the exercise you are giving is really functional, or if it will transfer over to sport or athleticism.

Enjoy the clip, but make sure to stop the video and read the slide; they have great information in them that you need to know.

Importance of Dynamic Correspondence

If you are unable to watch or listen to the video above, check out the transcription below.

…is defined by this concept of Dynamic Correspondence. And it’s a huge concept, it’s a long concept, it’s a little bit more of a complex concept, but Verkhoshansky and Siff in 1998, one of their published works, give criteria of Dynamic Correspondence. And whenever you think of Dynamic Correspondence really just think of specificity. How closely related is it to the movement in question. And so to give you an analogy, if you’re talking about throwing a shot put, how similar is throwing a discus compared to a shot put. How similar is swinging a bat to throwing a shot put. How similar is throwing a ball to throwing a shot put. That’s basically Dynamic Correspondence.

How well are those movements going to correlate to the movement you have in question. And these are some of the criteria of Dynamic Correspondence. You can read these on your own. I’m not really going to hash them because again it’s all about specificity, the amplitude and direction of movement goes back to the hip thrust. You’re on your back, how well is that going to translate whenever you’re on your feet. Force production has to be considered. What stages of the movement have the most force? Again, just check this out on your own time because there’s another slide here for Dr. Yessis in one of his works in 2006 that kind of puts this into light where he takes a theoretical runner and uses these categories for Dynamic Correspondence and tries to bring it into light. So he uses a runner and number one, where’s the ankle, knee and hip and shoulder? What is it doing and in what phase of the running motion? And it can get real complicated actually, real just intricate as you dial it down and try to become more and more specific. Luckily, for just muscle activation, will keep it on a more general level even though as you’ll see it will be specific, it won’t exactly be this specific.

Assessment & Exercise will be coming out next Tuesday for “Advance Screening”:

 

Rick Kaselj, MS

Before I go, a few kind words from Rebecca Tabbert about the work that I do:

If you are unable to watch or listen to the video above, check out the transcription below.

Hey, guys! This is Rebecca Tabbert at Fit Body Boot Camp Redlands and Calimesa. I just wanted to tell you about my good friend, Rick Kaselj. I am so proud and so excited for him and the success he’s found. I know that my first experience with him was watching him speak at Fitness Business Summit in person. However, I’ve followed his products over the years and if there is anybody that I want to go to in terms of muscle imbalances or corrective type exercises he is the man to go to. So I absolutely back anything that he puts out there. I believe that it’s quality product and I know that it’s based on a lot of time, effort, energy and most importantly research. He does the research so I don’t have to.
