How is the heart rate calculated using the RPE formula?

The Rate of Perceived Exertion (RPE) is a subjective measure that allows individuals to evaluate their exercise intensity. The formula for estimating heart rate based on RPE involves multiplying the RPE score by 10. This approach is based on the understanding that an RPE score of 10 usually corresponds to an all-out effort, which, for many individuals, can be linked to a heart rate of around 200 beats per minute. Therefore, when you multiply the RPE by 10, you derive an approximate target heart rate.

For instance, if someone rates their exertion as a 5 on the RPE scale, multiplying by 10 would suggest a heart rate of around 50% of their maximum heart rate, which is a moderate intensity. This method provides a straightforward way to translate perceived exertion into a more quantitative measure for physical training or assessment purposes. Understanding this relationship can help individuals gauge their workout intensity in a practical and subjective manner.
