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).
The basic formula for calculating maximum heart rate is to subtract your age from 220. Your target heart rate during exercise ranges from 50 percent to 85 percent of your maximum heart rate, depending on the intensity of the activity.However, this method for calculating maximum heart rate and target heart rate zones might be inaccurate for well-conditioned individuals or athletes.hile the normal resting heart rate for adults ranges from 60 to 100 beats per minute, conditioned athletes and other highly fit individuals might have normal resting heart rates of 40 to 60 beats per minute.
