This "fascia" stuff is fascinating. I looked up 'fascia' in wikipedia
and I thought the following paragraph was interesting:
Deep fascia can contract. What happens during the fight-or-flight response is an example of rapid fascial contraction . In response to a real or imagined threat to the organism, the body responds with a temporary increase in the stiffness of the fascia. Bolstered with tensioned fascia, people are able to perform extraordinary feats of strength and speed under emergency conditions.  How fascia contracts is still not well understood, but appears to involve the activity of myofibroblasts. Myofibroblasts are fascial cells that are created as a response to mechanical stress. In a two step process, fibroblasts differentiate into proto-myofibroblasts that with continued mechanical stress, become differentiated myofibroblasts.  Fibroblasts cannot contract, but myofibroblasts are able to contract in a smooth muscle-like manner.
Question for Mike Sigman: when you talk about "the fascia stuff", does it have anything to do with training the fascia to make it stronger and/or to "teach" it contract and relax?
