People all know that "life lies in sports". The latest research and statistics of scientists today show that "life lies in regulating one's physiological balance". Moderate and appropriate exercise contributes to health and longevity; Excessive strenuous exercise can only lead to premature aging and death. Anaerobic metabolic exercise refers to the strenuous exercise of muscles without continuous oxygen supply. Typical anaerobic metabolic sports include 100 m and 200 m races, as well as sports that use explosive force in high-intensity time, such as high jump, long jump, weightlifting and throwing. When engaged in these sports, although our heart and lungs try their best to enhance the oxygen supply to the muscles, they still can't meet the rapidly increasing demand for oxygen from the muscles of the limbs. Therefore, the blood vessels of brain, liver, kidney and gastrointestinal tract all contract, and blood is "squeezed out" to supply the muscles of limbs, which makes these organs in a state of hypoxia during exercise, which is very harmful to the body. Aerobic metabolic exercise is to speed up breathing and heartbeat through the efforts of the heart and lungs during exercise to meet the demand of limb muscles for oxygen, and the supply and demand of oxygen are in a dynamic balance during exercise. Aerobic metabolic exercise is a kind of exercise with light and moderate intensity, aiming at training physical endurance. In recent years, the most important breakthrough in sports and health research is to realize that light and moderate exercise (not strenuous exercise) is beneficial to health and longevity. Many people think that only after exercise, sweating, backache and leg pain are enjoyable, and there is a fitness effect. This is a completely wrong concept. Aerobic exercise includes brisk walking, jogging, cycling, skipping, yangko, fitness dance, skating and swimming. An important difference between aerobic and anaerobic metabolic exercise is the amount of exercise. How to judge whether our exercise belongs to aerobic metabolism? Heart rate is an index to measure exercise intensity. No matter what kind of exercise you do, if your heart rate is within the range of (220- age) ×60% to 80%, it is aerobic exercise. You can do this intensive exercise for 20 to 30 minutes three to five times a week, and the rest can do exercises such as Qigong, Tai Ji Chuan or walking to control tension. The way for the ancients to keep in good health is to recuperate and keep in good health, with a combination of movement and static, and movement cannot be neglected. It is not comprehensive to emphasize that "life lies in sports". It should be "life lies in adjusting one's physiological balance", and excessive strenuous exercise is not helpful to adjust one's physiological balance.

Therefore, it should be said that moderate and appropriate exercise contributes to health and longevity.
