The Borg Rating of Perceived Exertion Scale or RPE scale is a self-report tool to measure the intensity of physical work needed to do a particular activity.[1][2] The RPE scale was developed by Gunnar Borg, a Swedish researcher, in 1982, and measures on the scale have been found to be correlated with heart rate.[3][4]

Borg CR-10[edit | edit source]

Borg also developed the Borg CR-10 scale, which rates perceived from exercise intensity from 0 (no exertion) to 10 (maximum).[5]

Theory[edit | edit source]

The scale scores perceived effort from 6 (no effort at all) to 20 (absolute maximum, exhaustion). Fitter people feel like they are putting in less effort than less fit or deconditioned people who are doing the same activity.[1]

Evidence[edit | edit source]

The RPE scale has a high correlation with heart rate, and is particularly used in sports science.[4]

Cost and availability[edit | edit source]

The RPE scale is copyrighted but is widely available and free to use in many hospitals or health settings, and on websites such as the World Health Organization and CDC.
