[Supertraining] Re: Proprioceptive training

Hi,

The discussion on proprioceptive training is getting closer to the
question I asked as "What triggers a motor program". I've been reading
Schmidt's book "Motor Learning and Performance". It describes a
Conceptual model with various feedback loops with different durations.
Something happens even without motor programs and these "reflexes" can
be learned – but it's very difficult.

Eloranta has compared different kinds of jumpers and noticed that
their coordination changes and concluded that this is due to
"proprioceptive training". This is after years of doing a specific
type of exercises.
Eloranta, V. 2003. Influence of sports background on leg muscle
coordination in vertical jumps. Electromyography and Clinical
Neurophysiology, 43, 141–156.

I think that if you are doing a movement correct way and if your motor
system is working, best way to practice "proprioceptive nerves
system", is by doing "normal" Physical activity. BUT what if learned
not to stimulate motor units? Or if you are recovering from an
accident? How do we get the proprioceptive feedback working, if it's
not responding as it should?

This has been an issue in discussion about core stability, deep
muscles – and at the moment knee muscles? (If I understood this
correctly.)

I'd like to think that this is one of motor learning's basic
questions. It's easier when you do not have a "malfunction" – but
still it's the same. Our motor control needs to learn to activate and
get feedback from all the feedback loops – and most of the loops are
unconscious. – but can be affected by conscious control. (I mean the
conscious me still runs the show – even though it can mess up a good
performance.)
