What is the secret to muscle growth?

For male friends, a strong body of muscles can make them look stronger and more powerful, so more and more people are engaging in exercise, because exercise is the most scientific and effective way to help grow muscles. But have you ever understood the process of muscle growth? Here I will introduce to you the secrets of muscle growth in detail.

1. Muscles are mainly composed of muscle tissue. Myocytes are long and thin, fiber-like, so they are usually called muscle fibers. In traditional Chinese medicine theory, muscle refers to the general term for the body's muscle tissue and subcutaneous fat tissue. The spleen controls the movement of the whole body, and the nutrition of muscles comes from the spleen's transportation and transformation of water and grain essence.

2. Human muscles can be divided into three types according to their structure and function: smooth muscle, cardiac muscle and skeletal muscle. According to their morphology, they can be divided into long muscle, short muscle, wide muscle and orbicularis muscle. Smooth muscle mainly constitutes the internal organs and blood vessels, and has the characteristics of slow contraction, long-lasting and not easy to fatigue. Myocardial muscle constitutes the heart wall. Both do not contract according to human will, so they are called involuntary muscles. Skeletal muscle is distributed in the head, neck, trunk and limbs, and is usually attached to bones. Skeletal muscle contracts quickly, forcefully, easily fatigued, and can contract and relax according to human will, so it is called voluntary muscle. Skeletal muscle is observed in a horizontal pattern under a microscope, so it is also called horizontal muscle.

3. Skeletal muscle is the power part of the motor system. Under the control of the nervous system, skeletal muscle contracts and pulls bones to produce movement. There are more than 600 skeletal muscles in the human body, which are widely distributed and account for about 40% of body weight. Regardless of the size, each skeletal muscle has a certain shape, structure, position and auxiliary device, and has abundant blood vessels and lymphatic vessels, and is controlled by certain nerves. Therefore, each skeletal muscle can be regarded as an organ.

4. The head muscles can be divided into facial muscles (expression muscles) and masticatory muscles. The trunk muscles can be divided into back muscles, chest muscles, abdominal muscles and diaphragm muscles. The lower limb muscles are divided into hip muscles, thigh muscles, calf muscles and foot muscles according to their location, all of which are thicker and stronger than the upper limb muscles. This is related to supporting body weight, maintaining uprightness and walking.
