What are the characteristics of aerobic exercise

　　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 Heart, lungs and other organs can 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 cells, and the 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.
