Slow (Type I) muscle fibers have low myosin ATPase activity and high oxidative capacity, making them fatigue-resistant and suitable for postural muscles, while Fast (Type IIA) fibers have high myosin ATPase activity and high oxidative capacity.
Slow (Type 1) low myosin atpase activity w/ high oxidative capacity (long periods w/o fatigue) ex: postural muscles Fast (Type IIA) High myosin-ATPase activity w/ high oxidative capacity
