Lactic acid as a metabolic product in the muscle, there is no favorable role, a large accumulation can lead to muscle discomfort, a small number of people can appear lactic acidosis, the exercise process should pay attention to reduce the accumulation of lactic acid and strong lactic acid discharge. During intense or prolonged exercise of human skeletal muscles, due to the need for rapid energy production or the relative lack of oxygen supply to the skeletal muscles, glucose is oxidized anaerobically in the cells and lactic acid and ATP (the most important form of energy in the human body) are produced. Lactic acid buildup can lead to muscle swelling, soreness, and limitation of movement. In a small percentage of the population, lactic acidosis can occur, with low blood pressure, hyperventilation, impaired consciousness, vomiting, nausea, and rapid heartbeat. It is important to exercise in moderation, as this will reduce the buildup of lactic acid in the muscles. In addition, muscle relaxation, massage, warm baths, and rest can be performed after exercise, which will help the lactic acid that has been produced to be discharged from the body. You should also take care to replenish sugar, electrolytes, and protein after exercise. If a patient develops the above symptoms of lactic acidosis after exercise, he or she should be taken to the hospital immediately for resuscitation.
