I guess this would be a good place to ask this question:
To my understanding, static stretching should not be done before CNS stressful activities because it lessens the degree of power output.
Also, I have been told that static stretching longer than a few seconds (something like 4-5 seconds, not sure) causes proprioreceptors to fight against the stretch thereby eliminating the point of stretching any longer than that.
Having been told those two things, is this the reason that static stretching is not good before CNS stressful activities, because propriorecption has caused a tightening of these muscles and thereby decreases the ability for a stretch-reflex which is so important for such activities?
I'm not sure of the validity of any of this, could someone please clear up this matter for me?
