Abstract
Purpose: Rating of perceived exertion (RPE) is a convenient and cost-effective tool that can be used to monitor high-intensity interval exercise (HIIE). However, no methodological study has demonstrated the validity of RPE in this context. Therefore, the aim of this study was to validate and calibrate RPE for monitoring HIIE in adolescents. Methods: RPE, heart rate (HR) and oxygen uptake (V̇O2) data were retrospectively extracted from three lab-based crossover studies, with a pooled sample size of 45 adolescents, performing either cycling-based or running-based HIIE sessions. Within-participant correlations were calculated for RPE-HR and RPE-V̇O2, and receiver operator characteristic curve analysis was used to establish RPE cutpoints. Results: The results showed that RPE-HR demonstrated acceptable criterion validity (r = 0.53 - 0.74, p < 0.01), while RPE-V̇O2 had poor validity (r = 0.40 - 0.48, p < 0.01), except for HIIE at 100% peak power (r = 0.59, p < 0.01). RPE cut-points of 4 and 5 were established in corresponding to HR/V̇O2 based thresholds. Conclusion: RPE has some utility in evaluating intensity during lab-based running or cycling HIIE in adolescents. Future studies should expand the validation and calibration of RPE for prescribing and monitoring HIIE in children and adolescents in field-based contexts.
