title: The properties of skeletal muscle.
abstract: The authors review the musculoskeletal system and the controversy that surrounds methods for improving and strengthening it. Disorders brought on by over utilization, deficient working habits, lack of appropriate maintenance care and intercurrent stress and fatigue from repetitious daily tasks and poor sleeping habits are recognized and discussed. Also discussed are muscle structure and its relation to the contractive state, muscle energy requirements, motor control, source of muscle strength and factors modulating it, training adaptations in skeletal muscle, methods of strength training, erogenic aids including anabolic steroids and electrical stimulation and the pathologic states in muscles.
