As we all know, automobile engines work by burning gasoline, thus generating power.
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.
However, sports with high intensity, large amount of exercise and short time are generally anaerobic, such as 100m, 200m sprint, 100m swimming, high jump, weight lifting, push-ups, quick sit-ups, horizontal bar and parallel bars. The main function of anaerobic exercise is to exercise bones, muscles, joints and ligaments, strengthen tendons and bones, and prevent and treat cervical spondylosis, disc herniation and osteoporosis.
When people are doing strenuous and short-term sports, such as 100 meter race, the world-class elite sprinter has passed the finish line in about 10 second, but the oxygen he inhaled at the start has not yet reached the cells to participate in the activity of "burning" glucose, which means that the oxygen has not yet worked and the sports have ended.
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 jogging, and the glucose in your body has been 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.
Patients with type II diabetes, obesity and fatty liver must do aerobic exercise. People with arrhythmia and arteriosclerosis of the heart and brain, and the elderly should also do aerobic exercise. If it is to strengthen muscles, keep fit and prevent disc herniation, cervical spondylosis, osteoporosis and osteomalacia, then people should do anaerobic exercise.
