You should keep practicing until the fatigue period is over. Muscle aches are caused by sudden exercise leading to excessive lactic acid. It is suggested that drinking some milk will relieve it. At this time, you can appropriately reduce the amount of exercise, and slowly your body will keep up with your rhythm. \x0d\ In one case, muscle training causes pain. It is believed that after long-term contraction and relaxation of muscles, creatine metabolism between muscles increases, leading to soreness and pain. \x0d\ Suggestion: You can reduce the amount of exercise according to your own situation and let your body recover slowly. \x0d\ Acute soreness: muscle aches during exercise or in a short time after exercise. Acute soreness is related to the interruption of blood flow caused by muscle exertion. In the case of ischemia, metabolites can not be eliminated, but accumulate in muscles, thus stimulating pain receptors. You will fully recover in about a minute after you stop exercising. \x0d\ Chronic soreness: Chronic muscle soreness often occurs between 24 and 48 hours after training. The degree of chronic muscle soreness is related to the form of muscle contraction. Centrifugal contraction is the most likely to form chronic muscle soreness, while isotonic contraction is the least significant. When chronic muscle aches, muscle strength drops obviously. \x0d\ Causes of muscle soreness: During strenuous exercise, the human body not only breathes aerobically, but also breathes anaerobically (at this time, the energy provided by aerobic breathing is not enough for human consumption). The product of anaerobic respiration is lactic acid, which is acidic. The body absorbs lactic acid relatively slowly, and most of it stays in the body, so the muscles will feel sore. \x0d\ Hot compress sore local muscles to promote blood circulation. Static stretching exercise on sore parts is helpful to relieve spasm; Massage sore parts and relax muscles.
