Slow oxidative skeletal muscle fibers

Webb2 dec. 2024 · Exercise-induced signaling pathways in skeletal muscle that determine specialized characteristics of slow-twitch and fast-twitch muscle fibers. Oxidative fibers rely on aerobic respiration to fuel muscle contractions, and consist of slow-twitch (Type I) fibers, which are characterized as muscles with long contraction duration, associated … Webb12 dec. 2024 · This is likely explained by the fact that these slow oxidative mouse muscles contain a fiber type distribution in which 40–50% of fibers are type IIA . Thus, like in human skeletal muscle, it appears SLN may be expressed within mouse type IIA fibers where it can regulate SERCA1a; however, single fiber data from mice are required to confirm this.
