2. Control the amount of exercise according to age: In physical exercise, age is closely related to the amount of exercise. With the increase of age, the exercise ability of human body gradually decreases, and the amount of physical activity also decreases. At present, the value of 180- age is commonly used in sports activities as the highest heart rate of physical exercisers, that is, the heart rate of a 30-year-old person should not exceed 150 beats/min during physical exercise. However, the maximum heart rate of 70-year-old people participating in physical exercise should not exceed 1 10 beats per minute. This formula is widely used in physical exercise for the purpose of fitness.
3. Adjust the amount of exercise according to the morning pulse of the next day: Morning pulse refers to the number of pulses after waking up every morning. Generally, there are no special circumstances, and everyone's morning pulse is relatively stable. If the pulse does not change the next morning after physical exercise, it means that you are in good health or adapted to exercise; If the morning pulse on the second day after physical exercise increases more than 5 times/minute, it means that the activity on the previous day is too large, and the amount of exercise should be adjusted appropriately; If the long-term morning pulse increases, it means that the recent exercise is too large, so we should reduce the exercise or temporarily stop physical exercise until the morning pulse returns to normal.
