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.
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。
