本文综述了肌纤维的组织化学、超微结构、生化和生理特性。据报道，肌纤维收缩的速度与相对肌球蛋白atp酶活性（pH值9.4）成正比，而疲劳性与相对氧化能力有关。I型纤维atp酶活性低（pH值为9.4），收缩缓慢，氧化能力高，糖酵解能力低，抗疲劳能力相对较强。IIA型纤维具有较高的肌球蛋白atp酶活性（pH值9.4），收缩快，具有较高的氧化和糖酵解能力，并且相对抗疲劳。IIB型纤维肌球蛋白atp酶活性高（pH值9.4），收缩快，氧化能力低，糖酵解能力高，易疲劳。
This review describes muscle fiber types based on their histochemical, ultrastructural, biochemical, and physiologic properties. Reportedly the speed of muscle fiber contraction is directly proportional to relative myosin ATPase activity (at pH 9.4) while fatigability relates to relative oxidative capacity. Type I fibers have low ATPase activity (at pH 9.4), are slow twitch, have high oxidative and low glycolytic capacity, and are relatively resistant to fatigue. Type IIA fibers have high myosin ATPase activity (pH 9.4), are fast twitch, have high oxidative and glycolytic capacity, and are relatively resistant to fatigue. Type IIB fibers have high myosin ATPase activity (pH 9.4), are fast twitch, have low oxidative and high glycolytic capacity, and fatigue rapidly.
