Abstract: The purpose of this research was to determine if self-regulatory strength depletion induced by performing a modified Stroop task would influence rate of perceived exertion (RPE) during 30 minutes of treadmill exercise. Research indicates that self-regulatory strength can be depleted and performance on subsequent tasks that require self-regulation can be diminished (Muraven and Baumeister, 2000). Participants completed the modified Stroop task (experimental condition) and the color word task (control condition) before performing treadmill exercise at ventilatory threshold for 30 minutes. The modified Stroop task and the color word task were completed on separate days, and the order that participants completed tasks was randomly assigned. Self-regulatory strength depletion did not impact RPE, F(1,12) = 1.63, p > .05, partial ç2 = .12, or exercise heart rate, F(1,12) = .01, p > .05, partial ç2 = .00. Yet experiencing selfregulatory strength depletion on the first day resulted in significantly lower RPE when selfregulatory strength was not depleted on the second day, F(1,11) = 9.01, p < .05, partial ç2 = .45. The results of this study have implications for perceptions of future exercise sessions when selfregulatory strength is or is not depleted.
