1. Increase the total blood volume. Oxygen is supplied to all parts of the body with blood, and the increase of blood volume correspondingly enhances the oxygen delivery ability.

2. Enhance lung function. Aerobic metabolism accelerates the breathing of exercisers, thus increasing vital capacity and improving oxygen absorption ability.

3. Improve heart function and prevent the occurrence of heart disease. Aerobic metabolic exercise makes the heart muscle strong, excretes more blood at a time, and increases the proportion of high-density lipoprotein in the blood that can prevent coronary heart disease.

4. Increase bone density and prevent osteoporosis. With the increase of age, the calcium in human bones gradually decreases, so the elderly are prone to fracture. Aerobic metabolic exercise can effectively prevent the loss of calcium.

5. Reduce body fat and prevent obesity-related diseases. 6. Improve mental state and increase the ability to cope with various pressures in life. When a person lacks exercise, he often feels tired, depressed, has poor memory and even loses interest in work. Aerobic metabolic exercise can reverse this state and make people feel full and relaxed.
