With the continuous promotion of national fitness and the increasing awareness of public health, more and more people realize the importance of exercise. Let's talk about how to determine the intensity of exercise.

Heart rate, the simplest method is to determine the intensity of exercise by testing the heart rate during or after exercise.

Exercise intensity can also be determined by using some intelligent products. At present, some smart wearable products, such as smart bracelets and watches, can also monitor the heart rate through light sensing technology, but this light sensing technology is easily affected by the surrounding environment, so the measurement error during exercise is large and the accuracy is poor. However, these smart wearable products are relatively accurate when they are quiet and have certain reference value.

In sports data, the maximum oxygen uptake is the most basic and important data. It will directly reflect the running ability of runners.

Avoid excessive exercise, which will make the body tired, reduce immunity, and easily catch a cold and other upper respiratory diseases. Scientific hydration should be small, and it is not advisable to drink more water during exercise.
