The benefits of aerobic exercise, what are the benefits and purposes of aerobic exercise

The purpose of aerobic exercise is to enhance cardiopulmonary endurance. During exercise, a large amount of nutrients and oxygen is required due to muscle contraction, and the number of contractions of the heart increases, and the amount of blood sent out per pressure is also higher than usual. At the same time, the demand for oxygen also increases, the number of breaths is more than normal, and the degree of contraction of the lungs is also greater. Therefore, when exercise continues and the muscles contract for a long time, the heart and lungs must work hard to supply oxygen to the muscles and transport waste from the muscles. This continuous demand can improve the endurance of the heart and lungs. When the endurance of the heart and lungs increases, the body can engage in longer or higher intensity exercises, and is less likely to be tired. 　　The combustion of gasoline cannot be separated from oxygen, so we can also call the work of the engine aerobic exercise. Similarly, humans also need to burn fuel during exercise. Human "fuel" is sugar, protein and fat. These "fuels" of humans are stored in human cells. When you exercise, you will consume these "fuels" to gain power.

Same as engines burn gasoline, humans also need oxygen to help combustion when burning "fuel" (i.e. oxidation). People breathe in big mouths during exercise, so that the oxygen in the air enters the blood circulation system through the alveoli, and then flows into tissue cells throughout the body with arterial blood. This is a long process.

Low-intensity and long-term exercise are basically aerobic exercise, such as walking, jogging, long-distance slow swimming, cycling, dancing, etc. Aerobic exercise can effectively exercise the heart, lungs and other organs, and can improve the function of the cardiovascular and lungs. In the process of using oxygen, there is a considerable time difference, which determines that vigorous and short-term exercise becomes anaerobic exercise. When you exercise for a long time, oxygen has been dissolved into the cells, and the glucose in the body is fully "burned", thus transforming into new energy. Such exercise is aerobic exercise.

A lot of air is required, which is a good exercise for the heart and lungs, and can enhance lung capacity and heart function.

Long-term persistence in aerobic exercise can increase the hemoglobin in the body The amount of whitening can improve the body's resistance, anti-aging, enhance the work efficiency and cardiopulmonary function of the cerebral cortex, increase fat consumption, prevent arteriosclerosis, and reduce the incidence of cardiovascular and cerebrovascular diseases. If weight loss people arrange food reasonably while combining aerobic exercise, not only can they lose weight successfully, but their weight after losing weight will be consolidated. Aerobic exercise is also very beneficial for mental workers. In addition, aerobic exercise also has the effect of restoring physical fitness.

Patients with type 2 diabetes, obese patients and fatty liver patients must do aerobic exercise. People with arrhythmia, cardiocerebral artery sclerosis, and older people should also do aerobic exercise. If it is for strengthening muscles and tone body shape, prevent intervertebral disc herniation, cervical spondylosis, osteoporosis, and bone softening, Anaerobic exercise should be done.

If the heart rate reaches 150 to 160 beats/minute, the blood supply oxygen to the myocardium is insufficient, so it is semi-aerobic exercise.

If the heart rate reaches more than 160 beats/minute, it is anaerobic exercise, that is, the oxygen in the blood is already in short supply to the myocardium.

Methods require the participation of oxygen. Due to sufficient oxygen, aerobic exercise can completely metabolize nutrients in the body, that is, the final metabolism is achieved - nutrients It is explained into carbon dioxide and water. Carbon dioxide is excreted from the body through respiration, and water is "in and out of four": enter from the mouth and discharged through four channels: breathing, sweat, urine and defecation.
