In sport and everyday activities, the most important attribute of skeletal muscle is the ability to generate power, a product of strength and speed of movement. Many factors influence the muscle's ability to generate power. Training for muscular power requires special care in developing the proper exercise prescription. The need for muscular power runs across a spectrum of people from elite athletes attempting to optimize sports performance to the frail elderly trying to perform simple tasks. Power development is paramount to optimal neuromuscular function.
