Skeletal muscle fibers have been classified into fiber types based on contraction speed and metabolic capacity (Pette and Staron, 1990). The three classical fiber types are fast-twitch glycolytic (type IIB), fast-twitch oxidative/glycolytic (type IIA), and slow-twitch oxidative (type I), which vary from high to...
