subject: Aerobic exercise, is a new fitness way for people [print this page] Is it "aerobic exercise", the key standard of judging is 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, 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. 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. 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. 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, however the transportation of the blood is more than common, 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. However the demand with constantly, can improve the myocardial endurance. 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.
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. Usually people should open the mouth to breath when doing sport, 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.
Adequate oxygen supply, is indispensable for aerobic exercise, it is beneficial for heart and lung, improve the function of lung and heart.
Aerobic exercise lasts 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, 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 beneficial to worker with brain. Additionally, aerobic exercise can impact on physical recovery, bring about the positive effect.
