| This body type typically has very little medium-fast-twitch muscle fibers and a very fast metabolism. Because of the basic electrophysiology of nerve fibers, "induced exercise" necessitates use of relatively long pulse durations that will satisfy the prolonged chronaxies of denervated muscle fibers (pulse durations of at least 1 millisecond, but often 10-40 milliseconds and even up to 200 milliseconds are reported). You can also tear muscle fibers by stretching when you're cold, especially if you plop down into a split right before class. |
