Identification of training status differences using perceived exertion threshold.

We investigated if the rate of perceived exertion (RPE) threshold is as sensitive as the lactate threshold to detect training differences. Lactate and RPE thresholds were identified in well-trained cyclists and physically active males. Power output was higher in well-trained cyclists than in physically active individuals for both thresholds (p < 0.05). Our results suggest that RPE threshold is successful in discriminating differences between well-trained cyclists and physically active individuals.
