How do you determine a person's maximum heart rate?

The correct method to determine a person's maximum heart rate is by subtracting their age from 220. This formula provides a general estimate of the maximum number of times your heart can safely beat in one minute during intense physical activity. For example, if a 30-year-old wants to know their maximum heart rate, they would calculate it as 220 - 30, resulting in a maximum heart rate of 190 beats per minute. This approach is widely accepted in exercise science because it takes into account age-related cardiovascular changes, providing a simple yet effective guideline for individuals to monitor their exercise intensity safely.

The other choices do not accurately reflect how maximum heart rate is determined. Multiplying age by 2 or adding 10 to age would yield incorrect numbers that do not correspond to the physiological parameters of heart rate. Taking a pulse for one minute measures current heart rate but does not provide a method for estimating maximum heart rate based on age.
