In the process of physical exercise, it is best to control the heart rate between 80% and 90%, which is beneficial to mental health. High-intensity physical activity is equivalent to 70%~80% of the maximum oxygen uptake, that is, 80% ~ 90% of the highest heart rate; Moderate intensity is equivalent to 50%~60% of the maximum oxygen uptake, that is, 65% ~ 75% of the maximum heart rate; Small intensity is equivalent to about 40% of the maximum oxygen uptake and 60% of the maximum heart rate.

Extended data:

Controlling scientific exercise load means controlling the intensity, duration and frequency of physical exercise. Activity intensity is the work done by an individual in unit time. There is a corresponding relationship between human maximal oxygen uptake and heart rate. The intensity of physical exercise is closely related to oxygen consumption, and there is a certain percentage relationship between oxygen consumption and maximum oxygen intake. Therefore, people generally use heart rate index as the basis for evaluating exercise intensity.
