Anaerobic exercise comes from the classification of skeletal muscle metabolism during human exercise, and the concept of anaerobic exercise is also based on anaerobic metabolic energy supply system. For example, anaerobic exercise refers to the movement of human muscles in anaerobic energy metabolism. Anaerobic exercise is mostly exercise with high load intensity and strong immediacy, which is difficult to last and the time of fatigue elimination is slow.

Anaerobic exercise is relative to aerobic exercise. The metabolism of the body is accelerated during exercise, and the accelerated metabolism needs to consume more energy. The energy of human body comes from the catabolism of sugar, protein and fat. When there is not much exercise, such as jogging and dancing, the energy supply of the body mainly comes from the aerobic metabolism of sugar. The exercise that mainly depends on the aerobic metabolism of sugar is what we call aerobic exercise. When the sports we are engaged in are very intense or explosive, such as weightlifting, 100-meter sprint, wrestling and so on. At this time, the body needs a lot of energy instantly, but under normal circumstances, aerobic metabolism can't meet the needs of the body at this time, so sugar quickly produces a lot of energy through anaerobic metabolism. Exercise in this state is anaerobic exercise.

Features: The biggest feature of anaerobic exercise is that the oxygen uptake during exercise is very low. Because the speed is too fast and the explosive force is too strong, the sugar in the human body cannot be decomposed by oxygen, so we have to rely on "anaerobic energy supply". This kind of exercise makes the body produce too much lactic acid, which leads to muscle fatigue, muscle soreness and shortness of breath after exercise.

1 Aerobic exercise refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. Simply put, aerobic exercise refers to low-intensity, rhythmic exercise, which lasts for a long time (about 30 minutes or more) and has moderate or upper-middle intensity (60% to 80% of the maximum heart rate).

2 Evaluation criteria: whether it is "aerobic exercise" or not is measured by heart rate. Exercise with heart rate 150 beats/min is aerobic exercise, because blood can supply enough oxygen to myocardium at this time; So it is characterized by low intensity, fast pace and long duration. It is required to exercise for at least 30 minutes at a time and insist on 3 to 5 times a week. This kind of exercise, oxygen can not only fully burn (that is, oxidize) the sugar in the body, but also consume the fat in the body, enhance and improve the cardiopulmonary function, prevent osteoporosis, and adjust the psychological and mental state, which is the main exercise mode of fitness. Therefore, if you are overweight and want to lose weight through exercise, it is recommended to choose aerobic exercise, such as jogging and cycling.
