Abstract：
OBJECTIVE: 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.
CONCLUSIONS: 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.

摘要：
目的：感知劳累评分（RPE）是一种方便且具有成本效益的工具，可用于监测高强度间歇运动（HIIE）。然而,在这种情况下，没有方法学研究证明RPE的有效性。因此,本研究的目的是验证和校准用于监测青少年HIIE的RPE.
方法：RPE，心率(HR),和摄氧量(V•O2)数据从3个基于实验室的交叉研究中回顾性提取，合并样本为45名青少年，执行基于循环或基于运行的IIIE会话。计算了RPE-HR和RPE-V•O2的参与者内相关性，并使用接收器操作员特征曲线分析来建立RPE切点。
结果：结果表明，RPE-HR表现出可接受的标准有效性（r=.53-.74，P<.01），而RPE-V−O2的有效性较差(r=.40-.48，P<.01)，除了HIIE在100%峰值功率(r=.59，P<.01)。对应于基于HR/V•O2的阈值，建立了4和5的RPE切点。
结论：RPE在评估青少年实验室跑步或骑自行车HIIE时的强度方面具有一定的实用性。未来的研究应扩大RPE的验证和校准，以在基于现场的背景下在儿童和青少年中处方和监测HIIE。
