Exercise Physiology

Abstract

The knowledge about the broad range of exercise responses that can occur across time, intensities, and modes of exercise can help to improve work capacity and physical performance of humans in health and disease. Exercise alters physiological function in the organism, regardless of whether the effect is beneficial or harmful. Muscle contraction has both mechanical that produces movement and metabolic properties producing energy. Isotonic dynamic exercise shortens the muscle fibers. Static isometric exercise is an effort without fibers shortening. However, most physical activities involve both dynamic and static contractions and aerobic and anaerobic metabolism. Thus, activities tend to be classified on the basis of their dominant mechanical and/or metabolic characteristics.
