Maximum heart rate will usually be calculated using 220 – age.
1. Maximum heart rate refers to the highest number of beats per minute that an individual’s heart can make under maximum stress. The “220 – age” is an estimated formula. To know the maximum heart rate more accurately, it needs to be measured in a clinical setting using sophisticated laboratory equipment.
2. The maximum heart rate can be used to guide an individual’s exercise. The best range of heart rate control during physical activity is 65-85% of the maximum heart rate, which is the level of aerobic activity that is more beneficial to the patient’s health. The calculation of the maximum heart rate is also important for doctors to formulate exercise prescription, on the basis of which they can give patients more reasonable and healthier exercise guidance, so that they do not overdo exercise or exercise does not achieve the purpose of cardiopulmonary function.
