Because everyone's health and physical condition are different, the aerobic heart rate range of fitness exercise should also vary from person to person and from time to time. The following methods to determine the range of aerobic heart rate can be used for reference: 1, the aerobic heart rate of healthy people with good physique can be controlled at 120 ~ 180 beats/min, and can be subdivided into light exercise 120 ~ 140 beats/min and moderate exercise/kloc-. 2. If individualization is needed, a general formula can be used to calculate the reasonable heart rate in aerobic exercise = (maximum heart rate-quiet heart rate-age) ×q+ quiet heart rate. Maximum heart rate in formula ≈ 2 10; Quiet heart rate refers to the heart rate in a relatively quiet state before exercise; Q stands for the amount of exercise, less than 50% is a small amount of exercise, 50% ~ 75% is a moderate amount of exercise, and more than 75% is a large amount of exercise. If someone is 50 years old with a quiet heart rate of 76 beats/min and wants to do aerobic exercise with a small amount of exercise, determine the aerobic heart rate = (210-76-50) × 50%+76 =118 beats/min. 3. For middle-aged and elderly people, the simplest and safest method can be adopted, and the suitable aerobic exercise heart rate = 170- age. If you are 60 years old, when you take part in aerobic exercise, your heart rate should be controlled at170-60 =110 times per minute. For frail and elderly people, (170- age) ×0.9 can be selected for safety. It is worth noting that the above content is only a general rule, and it must be applied flexibly according to the specific situation in implementation. Health status, environment, season and mood in different periods will have certain influence on the choice of exercise amount. At this time, the intensity and time of exercise should be reduced accordingly, and the heart rate index should be reduced accordingly to ensure safety. In short, you should learn to count your heart rate (pulse) during exercise to control the amount of exercise. It not only provides a safety guarantee for people who participate in sports, but also helps to ensure the fitness effect of sports. We can practice touching the radial artery of the wrist or the submandibular artery of the mandible (chin) to count the pulse. If conditions permit, it is certainly more ideal to wear a heart rate meter.
