WebbAnd there are actually two forms of this enzyme; slow twitch fibers have an ATPase that hydrolyzes ATP slowly, and fast twitch fibers have an ATPase that hydrolyzes ATP quickly. Since myosin heads need ATP to reset, a lot of ATP is used by muscle fibers, and the main source for ATP is glucose. Webb3 dec. 2012 · Generally people are born with an average of 50% slow and 50% fast twitch fibres. Sprinters with proper training change this ratio to 80% fast twitch fibres in the leg muscles while marathon runners change the ratio with advanced training to 80% slow twitch fibres in the lower limbs muscles. Because fast twitch fibers use anaerobic …
