The difference between running high heart rate people and low heart rate people is that the maximum heart rate is different and the utilization of the maximum heart rate is different. The purpose of running is to promote health, reduce fat and improve endurance. The premise of safety and efficient realization of the purpose of running is to understand the maximum heart rate, and to determine the intensity of exercise through the maximum heart rate, which is calculated by the ratio of the current heart rate to the maximum heart rate during exercise. For people with high heart rate, the base heart rate during exercise is high, and the proportion of maximum heart rate is high. Tolerance during exercise is biased and fatigue is easier. For low heart rate people, the base heart rate during exercise is on the low side, the heart rate rises to the fatigue-prone maximum heart rate percentage of the space is large, and the exercise tolerance is better. Whether it is a high heart rate or low heart rate people exercise, we should pay attention to scientific and reasonable exercise, can not be overdrawn physical strength, so as not to cause the opposite effect.
