Aerobic exercise refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance.
Simply put, aerobic exercise refers to low-intensity, rhythmic exercise, which lasts for a long time (about 30 minutes or more) and has moderate or upper-middle intensity (60% to 80% of the maximum heart rate).
Extended data
The purpose of aerobic exercise is to enhance cardiopulmonary endurance. In the process of exercise, due to muscle contraction, a lot of energy and oxygen are needed, and the demand for oxygen increases. The number of heart contractions, the amount of blood pumped out each time, the number of breaths and the degree of lung expansion all increase. Therefore, when the exercise continues and the muscles contract for a long time, the heart and lungs must strive to provide oxygen to the muscles and take away the waste in the muscles. And this constant demand can improve the endurance of the heart and lungs. With the increase of cardiopulmonary endurance, the body can engage in longer or higher-intensity exercise, and it is less likely to get tired.
The combustion of gasoline is inseparable from oxygen, so we can also call the work of the engine aerobic exercise. Similarly, human beings burn fuel when they exercise. The "fuels" of human beings are sugar, protein and fat. These "fuels" of mankind are stored in human cells. When you exercise, you will consume these "fuels" to gain motivation.
Just as an engine burns gasoline, human beings also need oxygen to support combustion when burning "fuel" (that is, oxidation). People breathe heavily during exercise, so that oxygen in the air enters the blood circulation system through alveoli, and then flows into the tissues and cells of the whole body with arterial blood flow. This is a long process.
Low-intensity, long-term exercise is basically aerobic exercise, such as walking, jogging, long-distance slow swimming, cycling, dancing and so on. Aerobic exercise can effectively exercise the heart, lungs and other organs, and can improve the cardiovascular and pulmonary functions. In the process of using oxygen, there is a considerable time difference, which determines that intense and short-term exercise becomes anaerobic exercise. When you exercise long enough, oxygen has dissolved into cells, and the glucose in your body is fully "burned" and converted into new energy. Such 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 vital capacity and heart function.
Long-term adherence to aerobic exercise can increase the amount of hemoglobin in the body, improve the body's resistance, resist aging, enhance the efficiency of cerebral cortex and cardiopulmonary function, increase fat consumption, prevent arteriosclerosis, and reduce the incidence of cardiovascular and cerebrovascular diseases. If dieters combine aerobic exercise with reasonable food arrangement, not only can they lose weight successfully, but their weight will also be consolidated. Aerobic exercise is also very beneficial to mental workers. In addition, aerobic exercise can also restore physical fitness.
Metabolism needs the participation of oxygen. Aerobic exercise can completely metabolize nutrients in the body, that is, it can realize the final metabolism-nutrients are decomposed into carbon dioxide and water. Carbon dioxide is excreted through breathing, while water enters through the mouth and is excreted through breathing, sweat, urine and feces.
Aerobic exercise can achieve the effect of slimming. Walking for half an hour after dinner can adjust the consumption of fat in dinner, and then the consumption of protein.
