WebbSkeletal muscle fibers can be classified based on two criteria: 1) how fast do fibers contract relative to others, and 2) how do fibers regenerate ATP. Using these criteria, there are three main types of skeletal muscle fibers recognized (Table 10.5.1). Slow oxidative (also called slow twitch or Type I) fibers contract relatively slowly and use ...

WebbThe I- and H-bands are areas where thick and thin filaments do not overlap (this is why these bands appear paler under the microscope). The I-band exclusively contains thin filaments whereas the H-band contains exclusively thick filaments. Skeletal muscles are divided into two muscle fiber types:
