Hello, according to relevant information, aerobic exercise, also known as aerobic metabolic exercise, refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply. That is to say, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. It is characterized by low intensity, fast rhythm and long duration. Several indicators of aerobic exercise: A is carried out in an aerobic environment; B did not reach the level of being out of breath; C 3-5 times a week; D each time more than 20 minutes; E Exercise with an intensity between 60% and 80% of the maximum heart rate (220 years old). Therefore, aerobic exercise not only refers to aerobic exercise, but also belongs to aerobic exercise, such as jogging, cycling, swimming, skipping rope, playing badminton, doing yoga and climbing mountains. Three functions of aerobic exercise 1. Aerobic exercise improves health. As the saying goes, "Life lies in exercise". Aerobic exercise can make people inhale several times more oxygen than usual, promote tissue metabolism, make the body full of nutrition, and enhance muscle strength, endurance and body immunity. At the same time, the large muscle group continues to do rhythmic exercise, which not only exercises the muscles, but also drives the human circulatory system to strengthen its operation, obviously improving the nutrition and lipid metabolism of the heart, thus enhancing the cardiopulmonary function and exercising cardiopulmonary endurance. Therefore, strengthening physical fitness is beneficial to health. Second, shape a beautiful figure. Various aerobic exercises need to consume calories and burn body fat. The longer you exercise, the more fat you burn and the lower your body fat percentage. At the same time, during the exercise, the muscles are well exercised and the flexibility of the body is well enhanced, and finally the purpose of losing weight and shaping is achieved. Third, relieve mental stress. Aerobic exercise is a positive way of mood regulation. By transferring and regulating the excitability of the nervous system, it can relieve mental stress, balance mental state and improve sleep. Precautions for aerobic exercise Wei Qiang suggested that before aerobic exercise, it is best to eat some food one hour in advance, warm up, do some stretching exercises, exercise joint ligaments and stretch limbs and back muscles. These are warm-up activities, and then gradually enter a state of moderate intensity exercise. Don't rush to do strenuous exercise to avoid cramps and other accidents. In aerobic exercise, we should pay attention to the buffering of action and the coordination of breathing, and don't exercise excessively to get better exercise. Don't rush to rest after exercise. You need to do some stretching exercises to gradually relax your body. The aerobic exercise time should be more than 20 minutes each time, but it should not be too long. You need to grasp it according to your own physique to avoid excessive fatigue. After a period of exercise, you should moderately increase the daily exercise and intensity according to your own physique. Doing aerobic exercise also needs to pay attention to diet. In people's daily diet, the scientific proportion of each nutrient element should be: carbohydrate accounts for 50%-55%, protein accounts for 20%, fat accounts for 25%-30%, and the water required by human body is about 2000ml per day. During exercise, it is best to pay attention to replenish some water every 15-20 minutes. These exercises are not aerobic exercises. Light exercise is not aerobic exercise. Only a certain intensity of aerobic exercise can exercise the cardiopulmonary circulation function and improve people's physical strength, endurance and metabolic potential, which is the most valuable exercise. Therefore, walking and doing housework at ordinary times are not aerobic exercise. Strenuous exercise is not aerobic exercise. Because of its high speed and strong explosive force, the sugar in the human body cannot be decomposed by oxygen, so we have to rely on "anaerobic energy supply". These exercises are anaerobic exercises. This kind of exercise can easily lead to muscle fatigue and can't last long. Therefore, running, weightlifting, throwing, high jump and long jump are not aerobic exercises.
