2. Anaerobic exercise means that the human body does some high-speed and strenuous exercise in a short period of 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.
Extended data aerobic exercise is characterized by low intensity, fast pace and long duration. This kind of exercise, oxygen can fully burn (that is, oxidize) the sugar in the body, but also consume the fat in the body, enhance and improve the cardiopulmonary function, which is the main exercise mode of fitness. Common aerobic exercises include jogging, brisk walking, cycling, going up and down stairs, climbing mountains, skipping rope, long-distance swimming and so on.
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". Common anaerobic exercises include equipment practice, weight lifting and throwing, running, long jump and tug-of-war. Anaerobic exercise helps to increase muscles and shape muscle lines.
