Berstein’s Law is defined as “the process of mastering redundant degrees of freedom of the moving organ. In other words, its conversion to a controllable system”. We talked about in the Principles section the best way to control control movement or lack there is to take joints away during moving.
Does everyone agree with this method of joint function assessment? Is there another way to see potential during movement other than reducing joints at a given time?
Variability Question 2:
We have so many things to evaluate at once with movement, context determines function. Do we need to evaluate ROM based on the function that ROM serves or ROM based regardless of Function?
For the first question, I think context plays a role here. Do I have a complete novice that I’m starting at ground zero? Taking joints away and slowly adding them back in based on competency makes sense. It also sets the athlete up for success if they can master it and move on. If we have someone we know has been training well consistently, we’ve worked with previously, and/or have some sort of screening process on, then they’ll probably be able to start a little further up the simple -> complex continuum.
For question 2, I think we need to start with a full ROM. This is arguably the best indicator that we have that someone has “healthy” joints and a good knowledge of their body in space. If you can move pain free through full ranges of motion, I think it’s safe to say I probably don’t have to worry about orthopedic issues. Once that is established, I think it would be appropriate to look at ROM contextually. I immediately go to something like partial reps. It’s easier to do partial reps after a foundation of full reps than the other way around.
I think thats spot on the first answer. The idea of context and getting more detail seem to be really interdependent. Having a situation that requires more information determines the need to get more info.
Second answer, I have to say I am biassed in that the entire movement curriculum is based on that notion. But it does make sense, if we do not have range of motion, how can we have anything else? If we set ROM as the prerequisite, then we can have more form our training.
