Motor units may have different sizes. Small have separate thin nerve fibers innervate several muscle fibers, while the thicker nerve fibers of larger motor units are innervated by several thousand muscle fibers. At the beginning of the motion to include a thick nerve fiber, the need for stronger stimulation than that required for "inclusion" is more subtle. Thus, smaller, so-called slow twitch muscle fibers begin to decline sooner than the larger, fast twitch.
