What is aerobic exercise? Usually we call aerobic exercise for the phenomenon of exercise that needs adequate oxygen. Means oxygen is inhaled in the body is equivalent to the oxygen's demand, to reach the state of balance in physiologic.
Is it "aerobic exercise",
that measure with the heart rate, 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, simultaneously burn the calories in vivo, to strengthen and improve the function of myocardial, prevent osteoporosis, adjust psychological and spiritual state, all these are the major ways to physical fitness. So, if you are overweight, 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. Those exercises not only be conducive to burn calories, but also convenient to do.
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. When doing exercise, because of muscle contraction needs a lot of nutrients and oxygen, 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. Hence when the exercise with insistence, the muscle contraction with long time, then myocardial must be effort to supply the oxygen to muscle, and finish the task of waste transportation in the muscle. However the demand with constantly, can improve the myocardial endurance. When the myocardial endurance improve, there will enough energy to consume for training with long time or higher intensity, can keep the vigor.
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. The fuel that we said contains sugar, protein and fat. Human's fuel are stored in the cells of vivo, when you doing sport, need to burn the "fuel" in order achieve power.
Oxygen for human is equivalently important with burning "fuel" (means oxidation), just like engine burns the gasoline. 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, together with artery blood enter into the entire body's tissue cells, it 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. The obesity if can arrange the diet reasonably, simultaneously to combine with aerobic exercise, not only succeed in losing weight, also the weight after losing weight can be gotten consolidation. Aerobic exercise is helpful for mental worker. Additionally, aerobic exercise can impact on physical recovery, bring about the positive effect.
