Running is not necessarily an aerobic exercise. The key to aerobic and anaerobic exercise is whether the body’s oxygen supply can meet the demands of the exercise and whether it can allow the body to metabolize sugar completely. Running can be both aerobic and anaerobic exercise. If it is jogging, long-distance running, etc., the human body is required to supply a lot of energy, in the process of energy conversion to have oxygen participation, the respiratory system, the blood system are constantly running, this time running belongs to aerobic exercise. If it is a sprint, the requirements in a very short period of time to supply more energy, at this time the human body consumes sugar in anaerobic metabolism, this kind of belongs to anaerobic exercise. Therefore, running belongs to aerobic or anaerobic exercise, depends on whether there is enough warm-up, oxygen supply can meet the body’s needs, can not be generalized.
