Aerobic metabolic exercise is a durable exercise that aims at the body’s ability to inhale, transport and use oxygen. Throughout the exercise process, the body inhales roughly the same amount of oxygen as it needs, i.e., it achieves equilibrium. Therefore it is characterized by low intensity, rhythm, uninterrupted, long duration and low requirements for exercise skills. Aerobic metabolic exercise has the following effects: 1, control blood pressure, hypertensive effect on patients with hypertension; 2, increase the total amount of blood, enhance oxygen delivery capacity; 3, enhance the function of the lungs, improve the ability to inhale oxygen; 4, improve heart function, prevent heart disease; 5, increase bone density, prevent osteoporosis; 6, reduce excess body fat, prevent the occurrence of diseases related to obesity; 7. Improve the mental state and increase the ability to cope with various stresses in life. Aerobic metabolic exercise is a form of exercise that can promote overall physical and mental health, both to enjoy the pleasure of exercise and to get the effect of exercise. The ideal aerobic metabolic exercise must at least meet the following conditions. 1. A suitable exercise program. The criteria for this program are: (1) Comprehensive large muscle group activity that raises the exerciser’s heart rate to a certain range and maintains it for more than 20 minutes. (2) easy to do, interested, preferably lifelong can adhere to the exercise program. (3) Less restricted by conditions, can be carried out in most occasions and climatic conditions. According to the above conditions, the basic projects are: (1) walking: it is suitable for the elderly and overweight people, the advantage is that the movement is soft, not easy to be injured, the disadvantage is time-consuming. (2) running: it is a comprehensive movement of the perimeter, not only to improve the aerobic metabolic function, but also to enhance bone density, the advantage is that it does not require any technology, no equipment and venues, as long as there is a smooth road and cleaner air on it. The disadvantage is that the lower limb joints are under greater stress, such as incorrect posture or too much exercise prone to injury. (3) swimming: can improve the overall function of the cardiovascular system and enhance physical fitness, the buoyancy of the water to reduce the burden on the joints and ligaments, so it is very suitable for the elderly and overweight people, but the limitations are greater, the need for swimming pool conditions. (4) cycling: is the movement of the large muscle groups of the legs, but not very beneficial to the lower back, upper limb muscles also do not get enough exercise, (5) aerobics: is a newly emerging fitness program, popular among people, especially women, a set of 45 minutes of aerobics, can give a comprehensive exercise effect. 2, determine the heart rate of aerobic metabolic exercise. After choosing a suitable exercise program, we must determine the intensity of exercise should be achieved, usually measured by heart rate. Cardiovascular system can only be improved under a certain exercise intensity stimulus, but this intensity can not be too high, otherwise it becomes anaerobic metabolic exercise, the intensity of the heart rate range is called “effective heart rate zone”, usually calculated by age after the maximum heart rate, the formula is as follows: the highest heart rate for men = 205 – age / 2 Women’s maximum heart rate = 220 – age. For ordinary exercisers when exercising the effective heart rate range between 60% and 85% of the maximum heart rate is most appropriate, if less than 60% effect is not good, higher than 85% is too strenuous, especially the elderly is not very safe. This point varies from person to person, should pay attention to master. 3, the last point about the time of exercise, aerobic metabolic exercise three, four, five times a week can be, not necessarily every day practice, because its effectiveness is not much greater than five times. Each exercise must reach the effective heart rate range, and in this area to maintain more than 20 minutes.
