Sprint is an anaerobic exercise. Anaerobic exercise, as its name implies, is strenuous exercise in a state of "hypoxia". High load intensity, strong immediacy, difficult to last, such as weightlifting, sprint, fighting, bodybuilding training, etc.
2. Anaerobic exercise refers to the high-speed and strenuous 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. Anaerobic exercise is relative to aerobic exercise. The metabolism of the body is accelerated during exercise, and the accelerated metabolism needs to consume more energy.
The energy of human body comes from the catabolism of sugar, protein and fat. When there is not much exercise, such as jogging and dancing, the energy supply of the body mainly comes from the aerobic metabolism of fat. The exercise that mainly supplies energy through the aerobic metabolism of fat is what we call aerobic exercise. When the sports we are engaged in are very intense or explosive, such as weightlifting, 100-meter sprint, wrestling and so on. At this time, the body needs a lot of energy instantly, but under normal circumstances, aerobic metabolism can't meet the needs of the body at this time, so sugar quickly produces a lot of energy through anaerobic metabolism. Exercise in this state is anaerobic exercise.
3. The difference between anaerobic exercise and aerobic exercise
Aerobic exercise means that during exercise, the human body mainly decomposes and metabolizes oxygen, which reflects that the human body exercises physically under the condition of sufficient oxygen supply, and the energy generated by the metabolism of sugar, fat and amino acids is supplied to the body. It is characterized by low intensity, fast rhythm and long duration. The main purpose of aerobic exercise is to raise the heart rate and exercise the heart, which is why aerobic exercise is also called cardiovascular exercise.
In addition, aerobic exercise needs a lot of oxygen, and the energy consumed by the body is mainly carbohydrates and fat, so people who lose weight choose to do aerobic exercise. Moreover, aerobic exercise can prevent osteoporosis and adjust psychological and mental state, which is the first choice for fitness. Anaerobic exercise means that the human body does some high-speed and strenuous exercise in a short time, but when the human body tries its best to exercise, the oxygen supply is insufficient, or the sugar in the human body can't be decomposed by oxygen, so it has to rely on "anaerobic energy supply", that is, the sugar in the body generates energy in the form of anaerobic glycolysis to supply the needs of the body. Metabolites of anaerobic metabolism can only be sugar, not fat and protein. Therefore, the effect of slimming is far less than aerobic metabolism.
