Certainly I have been vocal, as are many, many others, against this notion that you need a neurological program for ill movement so that when they do happen in real life, you have some level of preparation for them.
I insist this is nonsense. I know full well the fastest way to dive on the floor for a loose ball or crouching to get a tupperware out of the cupboard does not allow for perfect joint by joint mechanics. I get that. I really do.
I just don’t think you need to practice it.
Here’s some verbage and thoughts that I have tried to think through…..
So an exercise with poor form is poor because you have shifted stress away from active muscles to passive ligaments, capsules, joint appoximations.
You can agree, right? (Heads shaking.)
And remember, I know passive ligaments, capsules, joints, discs, etc. all need some levels of stressful input on a regular basis for normal health. We agree more than you think, Michigan folks.
So if bad movement, like the real movements we have to do in regular life, put stress to ligaments, we should consider the ligaments. And we should consider the goal of why we are here in the first place, the preparation of a neural program for a movement.
Can I assume that a neural program for movement is a combination of afferent input from the system and efferent signals from the brain to control the pattern?
Well, my suggestion is that ligaments don’t have afferent pathways. The brain doesn’t tell ligaments what to do. The brain tells muscles what to do, and muscles move joints, which can then stress ligaments. But in that senario, the ligaments just do what they’re told. The very first time you go into an uncommon pattern, the ligaments get stressed. The program you are developing is neuromuscular. There are no ligaments in the neuromuscular system. The ligaments will do what they are told whether you are “prepped” for the movement or not. They are like pillars in your basement. Based on their constituency, they hold up the house without you telling them to. And if you bang into them a lot, they will progressively weaken. If you don’t bang into them, they will have as much strength to resist the bang when it comes.
The brain sends no efferent signals to ligaments.
Now there are tons of afferent signals that the ligaments send back to the brain for sensory integration. And when the ligament requires the inflammatory response or remodeling, the brain sends efferent signals for that to happen. That I agree with, but there is no communication with the brain and ligaments in movement organization.
So if the whole idea of training bad movement is to program the brain for preparedness and resiliency, and……
bad movement stresses ligaments that have only a finite capacity to resist stress, but……
the ligaments are not part of the neural connections of practicing movement, then………..
what is the point of training bad movement, if………
you can’t train a ligament’s capacity to resist stress?
