Aerobic exercise means people carry out physical training when there is sufficient 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 key standard of judging is heart rate, in the process of exercise, the heart rate gets to 150 times very minutes that is regarded as 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. It asks the time of every training not less than one hour, to insist three to five times every week.
With aerobic exercise, it makes full use of oxygen to glycols absolutely the sugar in the body, as well as consume the fat in the body, to strengthen and improve the function of myocardial, prevent osteoporosis, adjust psychological and spiritual state, all these are the major ways to physical fitness. Therefor when you are bothering about the weight, try to loss weight with doing exercise to get to the goal, advise you to select the aerobic exercise, like swimming, skating and other exercises. Those exercises not only be conducive to burn calories, but also convenient to do.
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 goal of aerobic exercise aims at strengthening myocardial endurance. While carry out exercise, it is necessary to supply a number of nutrients and oxygen for muscle contraction, and result in frequency of heart contraction to become faster, however the transportation of the blood is more than common, at the same time, the demand of oxygen goes with increasing, 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. 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. 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. Once people take exercise, need to breath with high frequency, 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. 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. In addition, aerobic exercise has the effect of physical recovery.
