Slow oxidative skeletal muscle fibers
WebbClassically, skeletal muscle fibers can be categorized according to their speed of contraction (myosin ATPase rate) and their resistance to fatigue. These classifications are in the process of being revised, but the basic types include: Slow twitch oxidative (type I)muscle fibers, Fast-twitch oxidative-glycolytic (Type IIA)muscle fibers, and Webb2 dec. 2024 · Using these criteria, there are three main types of skeletal muscle fibers. Slow oxidative (SO) fibers contract relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP. Fast oxidative (FO) fibers have fast contractions and primarily use aerobic respiration, but because they may switch to anaerobic respiration ...
