aerobic exercise is an adequate supply of oxygen the body in the conduct of the exercise. That process in motion, the human body needs oxygen inhaled equal to physical balance. In short, aerobic exercise is the rhythmic feel any movement, the movement takes longer (about 15 minutes or more), exercise intensity in the middle or upper level (maximum heart rate of 75-85%).

Common aerobic exercise include: walking, fast walking, jogging, skating, swimming, biking, tai chi, dance fitness dance, rope skipping / do aerobics and so on. Aerobic exercise is characterized by low intensity, rhythmic, uninterrupted and continuous, long time. With weight lifting, running, high jump, long jump, throwing a explosive compared to the non-aerobic exercise, aerobic exercise is a regular movement, for 5 minutes or more have the energy of movement.

The purpose of aerobic exercise improve heart and lung endurance. In the exercise, because the muscle contractions need a lot of nutrients and oxygen, will increase the number of heart contraction and blood volume of each pressure sent more than usual, while also increasing the demand for oxygen, respiratory rate was more than normal , Zhang received the degree of lung large. So when the campaign continued, prolonged muscle contraction, heart and lung would be hard to supply oxygen to the muscles divided, and carried away muscle waste. This continuous demand, can improve cardiovascular endurance. When the increase in cardiovascular endurance, body can be engaged in longer or higher intensity exercise, and less likely to fatigue.

Gasoline combustion can not do without oxygen, so we can work the engine is called aerobic exercise. Similarly, humans have to burn fuel in the movement, the human "fuel" is a carbohydrate, protein and fat. These human "fuel" is stored in the body's cells when you exercise, you consume these "fuel" for power.

With the engine burning gasoline, as human beings burn "fuels" (ie oxidation), they also need oxygen for combustion. People in the movement, breathing to breathe the air of oxygen into the blood through the alveoli into the circulatory system, and then with the blood flow to the body tissues, this is a long process.

Low-intensity, prolonged exercise, basically aerobic exercise, such as walking, jogging, slow long-distance swimming, biking, dancing. Aerobic exercise can effectively exercise the heart, lungs and other organs, can improve the cardiovascular and pulmonary function.

Use of oxygen in the process, there is a considerable time lag, the time difference determines the intense, short-term movement has become anaerobic. When you exercise long enough, the oxygen has been integrated into the small run, the body's glucose was sufficient "burn", which translated into new energy, such a campaign is aerobic exercise.

Aerobic exercise requires a lot of breathing, heart, lung is a very good exercise that can increase lung capacity and heart function.

In brief, aerobic exercise is sufficient supply of oxygen the body in the conduct of physical exercise. That process in motion, the human body needs oxygen inhaled equal to physical balance. And sports a long time (about 15 minutes or more), exercise intensity in the middle or upper level (maximum heart rate of 75-85%). Such as walking, brisk walking, jogging, skating, swimming, cycling, dance fitness dance, rope skipping / do aerobics and so on. Brisk walking which is recognized as a simple and effective aerobic exercise, because it does not require specialized facilities and equipment, and did not run impact on the knees (knees when running the impact).
