WebThere are two types of skeletal muscle fibres: fast-twitch - contract quickly - do not use oxygen well - tire quickly; slow-twitch - contract slowly - use oxygen well - keep going for a long time; WebReportedly 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.
