What does aerobic exercise refer to?

　　Aerobic exercise refers to physical exercise performed by the human body with sufficient supply of oxygen. exercise . That is, during exercise, the oxygen inhaled by the human body is equal to the demand, reaching a physiological balance state. Simply put, aerobic exercise refers to any rhythmic exercise with a long exercise time (about 15 minutes or more) and a moderate or upper-moderate exercise intensity (maximum heart rate 75% to 85%).

　　Common aerobic sports include: walking, brisk walking, jogging, skating, swimming, cycling, Tai Chi, fitness dance, rope skipping/aerobic exercise, ball sports such as basketball, football, etc. Aerobic exercise is characterized by low intensity, rhythm, uninterrupted and continuous, and long time. Compared with explosive non-aerobic exercises such as weightlifting, running, high jump, long jump, and throwing, aerobic exercise is a constant exercise that lasts for more than 5 minutes and still has energy left.

　　The purpose of aerobic exercise is to build cardiorespiratory endurance. During exercise, due to muscle contraction, a large amount of nutrients and oxygen are required. The number of heart contractions increases, and the amount of blood sent out per pressure is greater than usual. At the same time, the demand for oxygen also increases, the number of breaths is greater than normal, and the degree of contraction of the lungs is also greater. Therefore, when exercise continues and muscles contract for a long time, the heart and lungs must work hard to supply oxygen to the muscles and transport waste products from the muscles. This continuous demand can improve cardiopulmonary endurance. When cardiorespiratory endurance increases, the body can engage in exercise for longer periods of time or at higher intensity, and is less prone to fatigue.

　　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 "fuels" are sugars, proteins and fats. These "fuels" of humans are stored in the cells of the human body. When you exercise, these "fuels" will be consumed to obtain power.

　　Just like an engine burning gasoline, humans also need oxygen to support combustion when burning "fuel" (that is, oxidation). People breathe heavily when exercising, allowing oxygen in the air to enter the blood circulation system through the alveoli, and then flow to tissue cells throughout the body as the arterial blood flows. This is a long process.

　　Low-intensity, long-term exercise is 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 improve cardiovascular and pulmonary functions.

　　There is a considerable time difference in the process of people using oxygen. This time difference determines that intense, short-term exercise becomes anaerobic exercise. And when you exercise for a long enough time, oxygen has been dissolved into the fine running, and the oxygen in your body Grape Sugar is fully "burned" and converted into new energy. This kind of exercise is aerobic exercise.

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

　　Long-term aerobic exercise can increase the amount of hemoglobin in the body, improve the body's resistance, anti-aging, enhance the work efficiency of the cerebral cortex and cardiopulmonary function, increase fat consumption, prevent arteriosclerosis, and reduce cardiovascular and cerebrovascular diseases. disease incidence rate. If a dieter arranges food reasonably and combines it with aerobic exercise, not only can he lose weight successfully, but the weight after losing weight will also be consolidated. Aerobic exercise is also very beneficial for mental workers. In addition, aerobic exercise also has the effect of restoring physical fitness.

　　Type 2 diabetes patients, obese patients and fatty liver Patients must do aerobic exercise. People with arrhythmia, cardiovascular and cerebrovascular sclerosis, and older people should also do aerobic exercise. If you want to strengthen your muscles, build your body, and prevent intervertebral disc herniation, cervical spondylosis, osteoporosis, and osteomalacia, you should do anaerobic exercise.
