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 maximum heart rate can be estimated using the commonly used formula of 220 minus your age in years (220-age), or a more accurate formula 208 - 0.7 x age (Tanaka et al., 2001). These formula only give an estimation of maximum heart rate-ideally you should measure it.See the discussion on maximum heart rate.he maximum heart rate can be estimated using the commonly used formula of 220 minus your age in years (220-age), or a more accurate formula 208 - 0.7 x age (Tanaka et al., 2001).
