초록
The decrease of muscle power and muscle size between twenties and seventieswas about 30% and 40% respectively. The loss of muscle mass by aging resulted inthe decrease of muscle power. The loss of muscle mass was due to the decrease ofnumber of Type 1 fiber and Type II fiber and size of each muscle fiber. Theaging skeletal muscle didn’t show the loss of glycolysis capacity but showed 20%decrease of the oxidative enzymes and muscle vascularization. The vigorousendurance exercise training with graded intensity played a role in the vascularproliferation, increase of activity of oxidative enzymes and improvement of V02max. The graded resistance exercise also played a role in the muscle hypertrophyand increase of muscle power, if it performed with adequate intensity and period. The exercise adaptation of aging skeletal muscle prevented it from sarcopenia,provided the activity of daily living with great effect and provided the aging relateddisease, that is Type II diabetes mellitus, arteriosclerosis, hypertension, osteoporosisand obesity, with great effect.
