People who don't exercise regularly will have local muscle pain after strenuous exercise, which is related to energy metabolism inside muscles. Various forms of human movement are mainly accomplished through muscle contraction. Muscle contraction needs energy, which is mainly provided by the decomposition of carbohydrates in muscle tissue. In the case of sufficient oxygen, such as when the human body is resting, the sugar in the muscle is directly decomposed into carbon dioxide and water, releasing a lot of energy. However, when the human body is in strenuous activity, skeletal muscle needs a lot of energy urgently. Although the respiratory movement and blood circulation are greatly enhanced at this time, it still cannot meet the oxygen demand of muscle tissue, resulting in the muscle being temporarily in a state of hypoxia. Results Sugar was decomposed into lactic acid, and less energy was released. Lactic acid accumulates in large quantities in muscles, which stimulates nerve endings in muscle blocks to feel sore; The accumulation of lactic acid increases the osmotic pressure in muscle, causing muscle tissue to absorb more water and local swelling.

People who exercise regularly can get more oxygen and less lactic acid from carbohydrates during exercise, so muscles will not feel obvious pain. Therefore, we should do more exercise at ordinary times, get ready before exercise, and do some muscle relaxation activities after exercise to promote blood circulation, so that muscle pain can be relieved.

In addition, washing hot water can relieve muscle soreness.
