Aerobic exercise means people carry out physical training when there is enough oxygen to supply. Means oxygen is inhaled in the body is equivalent to the oxygen's demand, to reach the state of balance in physiologic.

How to measure aerobic exercise, the heart rate is an important indicator, the exercise volume that heart rate keeps 150 times every minutes is called aerobic exercise, as at the time adequate oxygen need to be offered by the blood for myocardial; so aerobic exercise comprises of the characteristics of low intensity, rhythm, longer duration. People are required to keep the training time at least one hour every exercise, and reach the goal of three to five times each week.

This kind of training, the oxygen can glycols completely the sugar in vivo, as well as consume the fat in the body, apart from that, myocardial function also be gotten the improvement, avoid osteoporosis, regulate psychological and spiritual, they are the main methods of exercise for physical fitness. Therefor when you are bothering about the weight, would like to use exercise to reach the target of losing weight, suggesting you to choose the aerobic exercise, such as jogging, riding bicycle and so on. These movements, on the hand that can play an important role of burning fat, on the other hand can be easy to carry out.

The common aerobic exercise includes these items: walking, jogging, skating, swimming, riding bicycle, of course like basketball together with football is a good option.

The principle of aerobic exercise is to strengthen myocardial endurance. While carry out exercise, it is necessary to supply a number of nutrients and oxygen for muscle contraction, cause the number of heart contraction to increase, and every time, volume of the blood is transported more than as usual, meanwhile, that requires more oxygen to be supplied, and the number of breathing are more than normal, the closing up degree of lung is larger. So movement constantly ought to cause muscle contraction for long time, and myocardial must offer adequate oxygen to muscle as possible as it can, and finish the task of waste transportation in the muscle. With the continuously demand, the myocardial endurance get improvement. Once increase the myocardial endurance, physical body just can engage in sport which needs time longer or higher intensity, and not easy to feel fatigue.

As we know, the gasoline can not be burnt alone, must burn with oxygen, so we also call the work of engine as aerobic exercise. The same to people, human also need to burn the fuel during doing sport. And the fuel comprises of sugar, fat and protein. Human's fuel are stored in the cells of vivo, when you doing sport, need to burn the "fuel" in order achieve power.

As the same as burning gasoline for engine, for human, when it involves in burning "fuel" (means oxidation), needs oxygen to assist. Usually people should open the mouth to breath when doing sport, make the oxygen in the air enter into the system of the blood circulation through alveolus, then along with artery blood flow to whole body's tissue cells, this is a long process.

Aerobic exercise needs a large amount of air to breath, it is good to train for heart and lung, can strengthen lung and heart function.

Aerobic exercise with insistence long time, can increase the number of hemoglobin in vivo, improve the immune system, resist the aging, strengthen the working efficiency of cerebral cortex and the function of myocardial, increase fat consumption, prevent arteriosclerosis, cut down the incidence rate of cardiovascular and cerebrovascular diseases. People who are overweight with balanced diet, meanwhile the effect will be better if training with aerobic exercise, the result of losing weight also will be stability. Aerobic exercise is beneficial to worker with brain. Additionally, aerobic exercise can impact on physical recovery, bring about the positive effect.
