Regular runners have a heart rate of 60-100 times/minute is considered normal. Regular running can train the strong function of the heart and increase the contraction force of the heart. The age of each person participating in running sports is not the same, and it is normal for the heart rate to be around 60-70 times/min or even lower than 60 times/min when the running training starts in the teenage period, because the long-term training increases the contraction force of the heart muscle, and the heart can meet the blood of the whole body tissues and organs although the contraction is less than 70 times/min. supply. The heart function of the group who started to participate in running only in middle and old age has been improved to different degrees, generally in 70-80 times/minute, they are energetic and also belong to healthy people. Some groups suffering from coronary heart disease also want to improve their physical quality through running, but after running and other quiet down to measure the heart rate, a long time can not be reduced to within 100 times / min, indicating that the amount of exercise is too much, need to adjust the amount of exercise or replace other forms of exercise in time to reduce the load on the heart. In short, the heart rate of normal people is 60-100 times/minute, and the heart rate of people who often run is even lower, which means better heart function.
