It is specific to each joint and depends on a number of variables, including the tightness of ligaments and tendons. Different exercises will promote fast twitch fibers, slow twitch fibers, or both. For example, a sprinter will have comparatively more fast twitch fibers, whereas a long distance runner will have more slow twitch fibers.
