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).
Determining normal heart rates by age depends solely on how in-shape you are, physically. That means how well your lungs and heart work when you're exerting yourself, according to the American Heart Association. For anyone over about 16 years, including seniors, a normal heart rate is between 60-100 beats per minute when youâre at rest. For well-trained athletes it drops to 40-60 beats per minute, regardless of age, the AHA says.
