After "heart rate 130" fitness exercise, the pulse can't be restored for several minutes, which means that the exercise is too large and it is necessary to mediate in time.

If you are over 55 years old, the most suitable exercise pulse is 120- 130 beats/min (or less than10-120 beats/min). For young people, 140- 150 times/minute is the appropriate amount of exercise.

It usually takes 5 minutes to return to a quiet heart rate (the heart rate drops very quickly after just stopping exercise). )

The pulse frequency of 6 seconds immediately after exercise was measured as the exercise heart rate, and the pulse frequency of 6 seconds was measured again at 1 min after exercise as the recovery heart rate.

Heart recovery rate = (exercise heart rate-recovery heart rate)/10

The higher the value calculated according to this formula, the faster and healthier the heart will recover.
