Aerobic exercise can be divided into aerobic exercise, anaerobic exercise and mixed exercise.

Aerobic exercise, also known as aerobic metabolic exercise, refers to the endurance exercise carried out by the human body under the condition of adequate oxygen supply. During the whole exercise, the amount of oxygen inhaled by the human body is roughly equal to the demand, that is, it reaches a balance.

Aerobic exercise is characterized by low intensity, rhythm, uninterrupted and long duration. Generally speaking, aerobic exercise is simple, such as walking, jogging, swimming, cycling, playing tennis, skating, skiing, playing Tai Ji Chuan, dancing and aerobic exercise. Aerobic exercise is the oxidative decomposition of sugar in the body under the condition of sufficient oxygen supply, which produces carbon dioxide and water and releases energy, and can last for 10 minutes to several hours. Because sugar can be fully oxidized and decomposed, there is no lactic acid accumulation in the body, which can consume body fat for a long time.

Aerobic exercise is the main way to lose weight. It requires people to exercise for 45~60 minutes at a time, and the heart rate should reach 120~ 140 times/minute during exercise, and it is advisable to persist for 3~5 times a week.

Anaerobic exercise is the anaerobic glycolysis of sugar when oxygen supply is insufficient, producing lactic acid. Lactic acid system can supply energy 10~ 180 seconds.

For example, 100m or 200m competitions need explosive high jump, long jump, weightlifting and throwing at high speed and for a short time. Because the speed is too fast, the sugar in the body can't be oxidized and decomposed, so we have to rely on "anaerobic energy supply". Exercise and Health Care Anaerobic exercise produces a large amount of lactic acid accumulation in the body, which leads to muscle aches and breathlessness during exercise, which has a great influence on the human body and is not suitable for fitness and health care.

In sports, there are many irregular and mixed events, and there are also the same events, which can be aerobic or anaerobic due to different sports methods. For example, long-distance running, easy jogging is aerobic exercise, and running in the whole race is anaerobic exercise.
