Physiology of weight-lifting exercise.
This review describes the major features of skeletal muscle adaptation to weight-lifting exercise. Changes in contraction time, fiber size, and possibly fiber number may result in response to prolonged weight-training. Effective strength-training programs, both for athletics and rehabilitation, require recognition of the concept of "specificity of training," realization of the tendency of human skeletal muscle to adapt differently to different forms of physiologic stress.
