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's features are 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.
With aerobic exercise, it makes full use of oxygen to glycols absolutely the sugar in the body, simultaneously burn the calories in vivo, 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, advise you to select the aerobic exercise, like swimming, skating and other exercises. 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 performances of aerobic exercise that used widespread contain: jogging, swimming, skating, and the basketball as well as football is also a good choose.
The principle of aerobic exercise is to strengthen myocardial endurance. When doing exercise, because of muscle contraction needs a lot of nutrients and oxygen, and result in frequency of heart contraction to become faster, and every time, volume of the blood is transported more than as usual, at the same time, the demand of oxygen goes with increasing, accompany with the volume of breath getting more, and lung's relaxation 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 transports the waste of muscle. With the continuously demand, the myocardial endurance get improvement. When the myocardial endurance improve, there will enough energy to consume for training with long time or higher intensity, can keep the vigor.
Learn from the practices, the burning of gasoline needs the resistance of oxygen, therefore we can regard 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. The burning of the "fuel" that stored in the body cells could offer a large amount of energy for doing exercise.
As the same as burning gasoline for engine, for human, when it involves in burning "fuel" (means oxidation), needs oxygen to assist. Once people take exercise, need to breath with high frequency, the oxygen in the air according to alveolus to reach the system of the blood circulation directly, 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 lasts long time, the quantity of hemoglobin will rise in the body, the immune system obtains improvement, control the aging, improve the working efficiency of cerebral cortex and the function of myocardial, burn the calories, avoid arteriosclerosis, reduce the occurrence of cardiovascular and cerebrovascular diseases. The obesity if can arrange the diet reasonably, 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. In addition, aerobic exercise has the effect of physical recovery.
