Abstract
Extensive research has been undertaken to determine the effects of programs of regular exercise on a variety of organ systems. Limb skeletal muscle, which functions to produce locomotion and maintain body postures, has been shown to adapt both physiologically and biochemically to exercise training. The extent of the adaptations is dependent on the nature and the intensity of the training program. Endurance exercise causes adaptations in rat skeletal muscle that are restricted to the slow-twitch fiber types, while studies evaluating high-intensity exercise (work bouts requiring >90% V02max) have shown exercise-induced adaptations in the biochemical and contractile properties of fast- as well as slow-twitch muscles. It is apparent that high-intensity exercise is more effective in recruiting and thus causing adaptations in the fast-twitch fiber type. The following study was undertaken to determine the effect of high-intensity exercise training on rat single fiber force, Vmax , the force-velocity relationship, stiffness, and force-pea relationship.
