WebbFast twitch fibers are the predominant fibers in the body. They respond quickly to stimuli and can generate a good deal of force. They have a large diameter due to the large amount of myofibrils. Their activity is fueled by ATP generated from anaerobic metabolism. Slow twitch fibers respond much more slowly to stimuli than fast twitch fibers.

WebbSlow oxidative (SO) fibers contract relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP. Fast oxidative (FO) fibers have fast contractions and primarily use aerobic respiration, but because they may switch to anaerobic respiration (glycolysis), can fatigue more quickly than SO fibers.
