Summary/Abstract: The aging is related with the process of sarcopenia, which is related with loss of muscle power and strength. The cause of the reduction of muscle power is the decreasing of the number of the muscle fibers, and especially the type II white fibers. With aging declines the muscle regeneration, while is disturb the activity of satellite and immune cells taking part in muscle regenerative process. With increasing age occurs loss of motoneurons in the spinal cord, which leads to denervation of the muscle fibers. Reduction of the testosterone level plays an important role for the reducing of muscle power. There are supporting data that endurance and strength training can slow and partially some of the age-depending structural and physiological changes in the human skeletal muscles
