Abstract
Human muscle has important individual characteristics and variations. We have looked at these individual characteristics and more importantly, the specific muscle fibers. These muscle fibers can be divided into two major types; slow twitch (Type I) and fast twitch (Type IIa and IIb) fibers. On average most muscles are composed of 50 percent Type I fibers and 25 percent each of Type IIa and IIb fibers. It is these fiber types that help the researchers determine a variety of things about the subjects’ abilities to succeed in specific areas of sport. Each person has different percentages of these different muscle fiber types. For example, a person with a high percentage of slow-twitch fibers might have an advantage in prolonged endurance events, while a person with fast-twitch fibers may be better at short term and explosive events.
