The ability state of human body changes day and night. Every day from 8: 00 to 12, from 14 to 17, muscle speed, strength and endurance are in the best condition. If you do physical exercise and sports training during this time, the effect will be better. But from 3: 00 to 5: 00, 12 to 14, it is in a relatively low state. If you are engaged in sports during this time, you are easy to get tired, and when the "load" is too large, the probability of sports injury is high.

Extended data:

The best exercise time refers to the best time for exercise, that is, from 3 pm to 5 pm. The study found that high-intensity exercise can be carried out two hours after meals; Moderate exercise should be arranged one hour after meals; Light exercise within half an hour after meals is the most reasonable.

The highest and lowest points of physical strength are controlled by the body's "biological clock", which generally reaches its peak at night.

For example, in the morning, when the human body performs strenuous exercise, it can stimulate the sympathetic nerve. This rapid change will cause a series of changes in the body, affect the mental state of the whole day, and be harmful to health. In addition, at this time, blood sugar is at a low level, and exercise consumes a lot of blood sugar, which easily leads to hypoglycemia. Afternoon sports are influenced by objective factors such as work, work and housework.

The highest and lowest points of human physical strength are controlled by the "biological clock" of the human body, and generally reach the peak in the evening. For example, the lowest point of oxygen absorbed by the body is at 6 pm; Heart beating and blood pressure regulation are most balanced between 5 pm and 6 pm, while the body's sense of smell, touch and vision are also most sensitive between 5 pm and 7 pm. So, on the whole, the effect of exercise at night is better. ?

In addition, the hormone activity of the human body is also in a good state between 4 pm and 7 pm, and the body's adaptability and nerve sensitivity are also the best. Therefore, experts advocate evening exercise, but in the evening time, we should pay attention to the intensity of exercise, otherwise too high intensity will excite sympathetic nerves and hinder sleep.
