Effects of Training
Training of muscle is typically divided into 2 major categories: endurance and strength training. Endurance training refers to exercise directed at improving stamina (the duration that a person can maintain strenuous activity) and aerobic capacity (V ̇ o2max), whereas strength training refers to exercise directed at improving the maximum force-generating capacity of muscle. There is evidence that training has a positive effect on aging skeletal muscle.2,27–30 Training-induced adaptations in skeletal muscle depend on the intensity, frequency, duration, and mode of exercise.30 –32 Appropriate exer- cise can alter, slow, or even partially reverse some of the age-related physiological changes that occur in skeletal muscle, including sarcopenia, reduced lean muscle
