The perceptual responses of individuals at different levels of physical fitness to absolute exercise intensities were compared. Perceived exertion, as measured by the Rating of Perceived Exertion scale, did not discriminate between subjects who were physically fit and those who were not, despite differences in physiological strain.

The differential results obtained when the perceived exertion levels of 19 high-fit and 17 low-fit women were assessed according to Borg's Rating of Perceived Exertion Scale and magnitude estimation suggests that the RPE scaling procedures may be tapping a very select component of the perceptual process. These results do indicate that the scaling…
