I've been reading about different kinds of muscle fibers (all for this huge exam I have on Wednesday--I swear I'm not obsessed!), and it occurred to me to wonder which kind martial artists have more of. The fast glycolytic fibers are the 'fast twitch' ones we're all familiar with, and are really only good for short bursts of intense energy. They tend to be smaller than the others, because of less blood and stuff. Then there's the slow oxidative fibers, which are the 'slow twitch' ones. These, as we know, are best at sustained contraction--ie: endurance. But what about the fast oxidative-glycolytic fibers? These are sort of in between, from what I've read, and have smaller capacities for both systems of ATP production. I'd think martial artists have more oxidative-glycolytic fibers, because they need strength to power their techniques, as well as stamina to keep from collapsing in an exhausted heap.
