Rate of Perceived Exertion (RPE)

Rate of Perceived Exertion (RPE): Rate of perceived exertion (RPE) is a subjective 1-10 scale for measuring exercise intensity based on how hard the effort feels, commonly used alongside heart rate in rowing training.

What is Rate of Perceived Exertion (RPE)?

RPE is a subjective intensity scale where 1 represents minimal effort and 10 represents maximal, all-out effort. In rowing, RPE correlates with but does not perfectly match heart rate zones: RPE 3-4 corresponds to UT2/steady state, RPE 5-6 to UT1/threshold, RPE 7-8 to anaerobic threshold, and RPE 9-10 to maximal effort. RPE is useful when heart rate data is unavailable or unreliable (e.g., during short intervals where HR lags behind effort). However, RPE is subjective and can be influenced by sleep, stress, hydration, and motivation. Most coaches use RPE alongside heart rate and split time for a complete picture of training intensity.

How Watta Uses Rate of Perceived Exertion (RPE)

Watta's Effort Score provides an objective alternative to subjective RPE by combining mechanical output (watts) with physiological data (heart rate). The 0-100 score and four-zone system (Recovery, Building, Training, Peak) give you a data-driven effort rating that eliminates the subjectivity of RPE.
