Aerobic exercise refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance.
Simply put, aerobic exercise refers to low-intensity, rhythmic exercise, which lasts for a long time (about 30 minutes or more) and has moderate or upper-middle intensity (60% to 80% of the maximum heart rate).
Whether it is "aerobic exercise" is measured by heart rate. Exercise with heart rate 150 beats/min is aerobic exercise, because blood can supply enough oxygen to myocardium at this time; So it is characterized by low intensity, fast pace and long duration. It is required to exercise for at least 30 minutes at a time and insist on 3 to 5 times a week.
This kind of exercise, oxygen can not only fully burn (that is, oxidize) the sugar in the body, but also consume the fat in the body, enhance and improve the cardiopulmonary function, prevent osteoporosis, and adjust the psychological and mental state, which is the main exercise mode of fitness. Therefore, if you are overweight and want to lose weight through exercise, it is recommended to choose aerobic exercise, such as jogging and cycling.
