Aerobic exercise, also known as aerobic metabolic exercise, refers to physical exercise carried out by the human body under the condition of adequate oxygen supply. The advantages of aerobic exercise are: it can increase oxygen intake and better consume excess calories in the body. That is to say, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. So it is characterized by low intensity, fast pace and long duration. It is required that the exercise time should not be less than 1 hour, and it should be carried out 3 to 5 times a week. Through this kind of exercise, oxygen can fully ferment the sugar in the body, 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.
Common aerobic exercises include: walking, jogging, skating, swimming, cycling, playing Tai Ji Chuan, dancing, doing rhythmic exercises, etc.
Anaerobic exercise refers to the high-speed and vigorous exercise of muscles in the state of "hypoxia" Anaerobic exercise is mostly exercise with high load intensity and strong immediacy, which is difficult to last and the time of fatigue elimination is slow. The biggest feature of anaerobic exercise is that the oxygen intake during exercise is very low. Because the speed is too fast and the explosive force is too strong, the sugar in the human body cannot be decomposed by oxygen, so we have to rely on "anaerobic energy supply". This kind of exercise makes the body produce too much lactic acid, which leads to muscle fatigue, muscle soreness and shortness of breath after exercise. If you want to make your body stronger, you can go to the gym to take part in anaerobic exercise. However, when exercising, it is best to listen to the guidance of the coach and choose a training plan that suits you.
What is aerobic exercise?
Human movement needs energy. If energy comes from aerobic metabolism (oxidation reaction) in cells, it is aerobic exercise. But if energy comes from anaerobic glycolysis, it is anaerobic exercise. During aerobic metabolism, full oxidation of 1 mol glucose can produce 38 atp (energy unit) energy; However, in anaerobic fermentation, 1 mol glucose only produces 2 atp. During aerobic exercise, glucose metabolism produces water and carbon dioxide, which are easily excreted through breathing and are harmless to human body. However, a large number of intermediate metabolites such as pyruvate and lactic acid are produced during glycolysis, which cannot be eliminated by respiration. When these acidic products accumulate in cells and blood, they become "fatigue toxins", which will make people feel tired and weak, muscle aches, difficulty breathing, rapid heartbeat and arrhythmia. In severe cases, acidosis will occur and the burden on liver and kidney will increase. Therefore, after anaerobic exercise, people will always be exhausted, and muscle pain will last for several days before it disappears.
Does light exercise count as aerobic exercise
Light exercise is not aerobic exercise, nor can it achieve the purpose of exercise. Only when aerobic exercise reaches a certain intensity can we exercise the cardiopulmonary circulation function and improve people's physical strength, endurance and metabolic potential, which is the most valuable exercise. In other words, aerobic exercise is meaningful only if it reaches or approaches the upper limit. The limit of this upper limit is different for everyone.
