Aerobic training:

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).

The purpose of aerobic exercise is to enhance cardiopulmonary endurance. In the process of exercise, due to muscle contraction, a lot of energy and oxygen are needed, and the demand for oxygen increases. The number of heart contractions, the amount of blood pumped out each time, the number of breaths and the degree of lung expansion all increase. Therefore, when the exercise continues and the muscles contract for a long time, the heart and lungs must strive to provide oxygen to the muscles and take away the waste in the muscles. And this constant demand can improve the endurance of the heart and lungs. With the increase of cardiopulmonary endurance, the body can engage in longer or higher-intensity exercise, and it is less likely to get tired.

Anaerobic training, namely strength training;

The classification of anaerobic exercise comes from the classification of skeletal muscle metabolism during human exercise. At present, the concept of anaerobic exercise is mainly based on anaerobic metabolic energy supply system. For example, anaerobic exercise refers to the exercise of human muscles under anaerobic energy metabolism. But what we think of as anaerobic exercise in our daily life refers to the high-speed and strenuous exercise of muscles in the state of "hypoxia". 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.
