The period of rapid muscle development is during a person’s adolescence, and adolescent development is the fastest, including the growth and lengthening of muscles, the increase in muscle coverage as well as the thickness and toughness of muscles. Secondly, another sensitive period of muscle development is the stimulation of muscles through repeated and continuous physical exercise. Muscle is composed of myocytes, myocytes belong to the body’s stable cells, the so-called stable cells are myocytes do not divide and proliferate, muscle enlargement is mainly due to the hypertrophy of myocytes caused by myocytes, myocyte organelles within the myocyte, organelles repeatedly apply energy, so lead to compensatory enlargement, is the principle of muscle enlargement. If you want to make the muscle grow quickly to continuous, heavy exercise, to ensure adequate anaerobic exercise, and then the energy supply. The energy supply comes from diet, a good diet, high fat, high protein diet helps muscle growth, but also have enough sleep, adequate sleep is the basis of muscle growth. In addition, male muscle growth fast thanks to the secretion of male hormones, androgen helps muscle growth, so to ensure a healthy physical condition as well as sexual function also help muscle growth.
