Knowing your maximum heart rate helps determine how hard you are working out.
Knowing your maximum heart rate helps you measure how hard you are working when you exercise. The traditional formula for finding your maximum heart rate is subtracting your age from 220. For example, a 70 year old would have a maximum heart rate of 150. Other formulas, such as the Miller formula or the Londeree and Moeschberger formula, are more complicated.
Instructions
1. Multiply your age by 0.711 and subtract the result from 206.3 to find your maximum heart right, according to Londeree and Moeschberger. For example, if you are 45, multiply 45 by 0.711 to get 31.995 and subtract 31.995 from 206.3 to find your maximum heart rate to be 174.305.
2. Multiply your age by 0.85 and subtract the result from 217 to find your maximum heart right, according to Miller. For example, if you are 45, multiply 45 by 0.85 to get 38.25 and subtract 38.25 from 217 to find your maximum heart rate to be 178.75.
3. Compute your maximum heart rate by multiplying your age by 0.7 and subtract the result from 207, according to researchers at Oakland University. For example, if you are 45, multiply 45 by 0.7 to get 31.5 and subtract 31.5 from 207 to find your maximum heart rate to be 175.5.
4. Multiply your age, if you are a male, by 0.55 and subtract the result from 202 to find your maximum heart right, according to John Moores University. For example, if you are 45, multiply 45 by 0.55 to get 24.75 and subtract 24.75 from 202 to find your maximum heart rate to be 177.25.
5. Multiply your age, if you are a female, by 1.09 and subtract the result from 216 to find your maximum heart right, notes John Moores University. For example, if you are 45, multiply 45 by 1.09 to get 49.05 and subtract 49.05 from 216 to find your maximum heart rate to be 166.95.
