There are few practical methods available for evaluating training loads (TL) during swimming. The purpose of this study was to examine the ecological validity of the session-rating of perceived exertion (RPE) method for quantifying internal TL in competitive swimmers using heart rate (HR)-based methods and distance as criterion measures. This study also examined the correspondence between athlete and coach perceptions of internal TL using the session-RPE method. Twelve (six male, six female) well-trained swimmers (mean +/- SD: age 22.3 +/- 3.1 years, weight 71.8 +/- 11.6 kg, height 175.0 +/- 9.0 cm) participated in this study. All subjects completed a swimming step test to evaluate individual HR zones and blood lactate profile before undertaking 20 swim training sessions where RPE, HR, and distance covered were recorded. Training load was then calculated for each session using the session-RPE, HR-based methods, and session distance. The session-RPE scores were correlated to HR-based methods for measuring internal TL as well as training distance for each swimmer. All individual correlations between session-RPE, HR-based methods (r = 0.55-0.94; p < 0.05), and distance measures (r = 0.37-0.81; p < 0.05) were significant. Two-way ANOVA showed that there was a significant interaction for training intensity x coach-athlete perception, indicating that coach RPE was lower than athlete RPE for low-intensity sessions and higher than athlete RPE at high-intensity sessions. The results of this study suggest that session-RPE may provide a practical, noninvasive method for quantifying internal TL in competitive swimmers.
目前几乎没有实用的方法可用于评估游泳过程中的训练负荷（TL）。本研究的目的是使用基于心率（HR）的方法和距离作为标准测量指标，检验主观用力程度分级（RPE）方法在量化竞技游泳运动员内部训练负荷方面的生态效度。本研究还使用训练课RPE方法检验了运动员和教练对内部训练负荷感知的一致性。12名（6名男性，6名女性）训练有素的游泳运动员（平均±标准差：年龄22.3±3.1岁，体重71.8±11.6千克，身高175.0±9.0厘米）参与了本研究。所有受试者在进行20次游泳训练课之前完成了一项游泳阶梯测试，以评估个人心率区间和血乳酸水平，在训练课中记录RPE、HR和游过的距离。然后使用训练课RPE、基于心率的方法和训练课距离为每个训练课计算训练负荷。训练课RPE分数与基于心率的测量内部训练负荷的方法以及每名游泳运动员的训练距离相关。训练课RPE与基于心率的方法（r = 0.55 - 0.94；p < 0.05）和距离测量值（r = 0.37 - 0.81；p < 0.05）之间的所有个体相关性均具有显著性。双向方差分析表明，训练强度×教练 - 运动员感知存在显著交互作用，表明在低强度训练课中教练的RPE低于运动员的RPE，而在高强度训练课中高于运动员的RPE。本研究结果表明，训练课RPE可能为量化竞技游泳运动员的内部训练负荷提供一种实用的、非侵入性的方法。
