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. WebGlycogen can be broken down to quickly generate glucose for glycolysis. Function: seen in higher proportion in muscles which do fast, high precision movements (e.g. eye movements).
