Generally, exercise heart rate is used to measure aerobic exercise and anaerobic exercise. The heart rate of aerobic exercise is generally below 140 beats/min, that is, the pulse beats 14 beats /6 seconds, breathing evenly and long, and the body feels happy, which is aerobic exercise. This kind of exercise is beneficial to the burning and consumption of body fat, and at the same time accelerates the excretion of body toxins (sweating and diuresis), and the body function and immune system will be strengthened.

If it exceeds 160 times/min, it means anaerobic exercise, shortness of breath and poor body feeling. In this state, the body is in a state of hypoxia, which leads to passive shortness of breath to fill the negative oxygen state of the body, and the passivity of heart function is strengthened. Anaerobic exercise only increases the body's emergency state ability, which is very bad for the body in the long run.

Aerobic exercise, also known as aerobic metabolic exercise, refers to physical exercise carried out by the human body under the condition of adequate oxygen supply. That is to say, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. So it is characterized by low intensity, fast pace and long duration. It is required that the exercise time should be no less than 1 hour, 3 ~ 5 times a week. This kind of exercise, oxygen can fully ferment the sugar in the body, 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. Common aerobic exercises include: walking, jogging, skating, swimming, cycling, playing Tai Ji Chuan, dancing, doing rhythmic exercises, etc.

The so-called anaerobic exercise refers to the high-speed strenuous exercise of muscles in the state of "hypoxia". Such as running, weightlifting, throwing, high jump, long jump, tug-of-war, muscle strength training and so on. 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 produces too much lactic acid in the body, which leads to muscle fatigue, muscle soreness and shortness of breath after exercise, which has a great influence on the human body and is not suitable for fitness and health care.
