Abstract

Objective The aim of this study was to propose a new method that allows for the estimation of critical power (CP) from non-exhaustive tests using ratings of perceived exertion (RPE). Methods Twenty-two subjects underwent two practice trials for ergometer and Borg 15-point scale familiarization, and adaptation to severe exhaustive exercise. After then, four exercise bouts were performed on different days for the estimation of CP and anaerobic work capacity (AWC) by linear work-time equation, and CP15, CP17, AWC15 and AWC17 were estimated using the work and time to attainment of RPE15 and RPE17 based on the Borg 15-point scale. Results The CP, CP15 and CP17 (170–177 W) were not significantly different (P > 0.05). However, AWC, AWC15 and AWC17 were all different from each other. The correlations between CP15 and CP17, with CP were strong (R = 0.871 and 0.911, respectively), but the AWC15 and AWC17 were not significantly correlated with AWC. Conclusion Sub-maximal RPE responses can be used for the estimation of CP from non-exhaustive exercise protocols.
