(RPE)

A numerical scale, rating an individual's own subjective assessment of how hard he or she has worked during a physical activity. The Borg scale, devised by the Swedish physiologist Gunnar Borg, originally consisted of 15 grades from very, very light to very, very hard exertion. This has been modified in the New Borg Scale to take into account the fact that exercisers become more sensitive to changes of exertion at higher work rates. The Ratings of Perceived Exertion follow changes in heart rate quite closely and are therefore regarded as reasonably accurate estimates of actual exertion. The average RPE associated with physiological adaptation to exercise is 12–16 (‘somewhat hard’ to ‘hard’) on the Borg scale. See also TRIMP.
