This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm).
One way of monitoring physical activity intensity is to determine whether a person's pulse or heart rate is within the target zone during physical activity. For moderate-intensity physical activity, a person's target heart rate should be 50 to 70% of his or her maximum heart rate.This maximum rate is based on the person's age.An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220.
