Cindy said: In the past few nights, people who insist on exercising to lose weight often feel sore all over. After strenuous exercise, they will feel sore all over, which is related to the energy metabolism inside the 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. 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. It hurts all over. Lactic acid accumulates in large quantities in muscles, which stimulates nerve endings in muscle blocks to feel sore; The accumulation of lactic acid makes the osmotic pressure in muscle increase, which causes muscle tissue to absorb more water and ache all over. People who exercise regularly will not feel sore all over. Muscle can get more oxygen during exercise, and less lactic acid is decomposed by sugar, so muscle will not have obvious pain. Bian Xiao reminded: The best way to avoid physical pain after exercise is to exercise from shallow to deep, and exercise step by step to lose weight, so that the weight loss effect is good and you can exercise well.
