Is the rating of perceived exertion (RPE) a valid tool for monitoring high-intensity interval exercise intensity compared to heart rate and oxygen uptake in adolescents?
Rating of perceived exertion shows acceptable validity for monitoring heart rate-based intensity during lab-based high-intensity interval exercise in adolescents, with scores of 4 or 5 corresponding to target thresholds.
Effect estimate: r = 0.53-0.74
p-value: p=<0.01
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 (V˙O2) data were retrospectively extracted from 3 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-V˙O2, and receiver operator characteristic curve analysis was used to establish RPE cut points. RESULTS: The results showed that RPE-HR demonstrated acceptable criterion validity (r = .53-.74, P < .01), while RPE-V˙O2 had poor validity (r = .40-.48, P < .01), except for HIIE at 100% peak power (r = .59, P < .01). RPE cut points of 4 and 5 were established in corresponding to HR/V˙O2 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.
Liu et al. (Mon,) conducted a observational in Healthy adolescents (n=45). Rating of perceived exertion (RPE) vs. Heart rate (HR) and oxygen uptake (VO2) was evaluated on Criterion validity of RPE-HR (within-participant correlation) (r = 0.53-0.74, p=<0.01). Rating of perceived exertion demonstrated acceptable criterion validity for monitoring high-intensity interval exercise in adolescents when correlated with heart rate (r = 0.53-0.74, p < 0.01).
