"Aerobic exercise" is not a movement of oxygen.

<P> Many people know that "aerobic exercise" good for you, but what exactly is "aerobic exercise", most people can not clear where we stand, and some even think that aerobic exercise is intuitive enough in oxygen environment .movement. .In fact, is not "aerobic exercise", the standard measure of heart rate. .</ P> <P> former director of China Institute for Tourism Studies Department of diet, acupuncture, Chinese Academy of International Esperanto Association Class Speaker Speaker Professor Zhao Hongbin told reporters: heart rate remained at 150 beats / minute of exercise is aerobic exercise, because blood can be supplied at this time .adequate myocardial oxygen; </ P> <P> If the heart rate of 150 ~ 160 times / min, this time the blood on myocardial oxygen supply is not sufficient, then the semi-aerobic exercise; if the heart rate reached 160 beats / min or more, then .as anaerobic exercise, and that oxygen in the blood is in short supply on cardiac. .</ P> <P> metabolism requires the participation of oxygen, because oxygen-rich aerobic exercise, metabolism of nutrients the body can completely, that is, to achieve the ultimate metabolism of nutrients --- decomposed into carbon dioxide and water. .</ P> <P> carbon dioxide excreted through the breath, the water is "into a four": from the mouth into, through breathing, sweat, urine, feces discharged four ways. .Anaerobic exercise the lack of oxygen, the body material in the metabolic process can not be completely decomposed into carbon dioxide and water. .</ P> <P> but produce ethanol, acetic acid and lactic acid, and many other harmful acids --- that people on the stairs or walking legs are sore, it is the body in anaerobic conditions, lactic acid caused by excessive .The. .</ P> <P> healthy human body fluids were slightly alkaline PH value, 7.4. .A lot of ethanol, acetic acid and lactic acid can make fluid changes, so that his body acidosis, a serious but also death. .Anaerobic exercise in damage of the heart, but also to the whole body metabolic failure. .</ P> <P> strong movement in the sudden death occurs, one of the reasons is the anaerobic exercise on the body of such damage. .In addition, in the workplace in the "death from overwork", Yongnaoguodu fatigue syndrome and other phenomena are related to the body that insufficient supply of oxygen. .</ P> <P> often say, "Movement in moderation", is based on the above reason, and regular exercise also vary. .For most people, how to grasp the degree of it? Professor Zhao Hongbin to tell the reader, exercise to keep the "aerobic" state is: Weihan basis, not sweating. .</ P> <P> In addition, the movement generated by the next day whether the elimination of fatigue, is also a measure of aerobic exercise is not a standard: are fatigue after exercise, but if that is able to resume the next day, then is normal; if .Fatigue can not be eliminated the next day, then the excessive movement, and is beyond the scope of aerobic exercise. .</ P> <P align=right> (internship Editor: He Lili) </ P>.
