WebbSkeletal muscle is made up of thousands of muscle fibres that run the length of the muscle. Each muscle fibre consists of many contractile units called myofibrils which run the length of each muscle fibre. Individual muscle fibres are wrapped with fascia and then further bound together by more fascia into bundles called fascicules. WebbPower athletes have a higher ratio of fast-twitch fibers (e.g., sprinters 70-75% type II), whereas for endurance athletes have more slow-twitch fibers (e.g., marathon/distance runners 70-80% type I) (2).
