The purpose of this study was to examine the validity of the use of ratings of perceived exertion (RPE) to estimate and regulate exercise intensity during rowing ergometry. Nine competitive male rowers [mean age 28.6 years, (SD 6.3)] completed two rowing trials on an ergometer. The first trial (estimation) consisted of an incremental protocol designed to elicit a range of work outputs (WO) and heart rates (HR). The subjects indicated their perception of effort using a 15-point scale at each intensity level. In the second trial (production), 7-14 days later, the subjects were asked to produce exercise intensities corresponding to five levels of RPE: 15, 11, 17, 13, and 19. Data analysis revealed high Pearson correlation coefficients between HR and RPE (r = 0.95, P < 0.01) and WO and RPE (r = 0.96, P < 0.01) during the estimation trial. In addition, significant correlations (P < 0.01) were obtained between the estimation and production trials for HR (r = 0.82) and WO (r = 0.84). Posthoc analysis of variance revealed that the observed differences in mean HR were not significant (P > 0.05) at three of the five intensity levels (RPE 15, 17 and 19), but were at the two lowest RPE levels (11 and 13). Significant mean differences in WO were seen at all but RPE 17. These data support the validity of the RPE scale as a measure of physiological strain among competitive male rowers, and offer support for its use as a method of regulating the intensity of rowing ergometry, especially at higher levels.
本研究的目的是检验使用主观用力程度分级(RPE)来估计和调节划船测力试验期间运动强度的有效性。九名男性竞技划船运动员[平均年龄28.6岁,(标准差6.3)]在一台测力计上完成了两次划船试验。第一次试验(估计)包括一个递增方案,旨在引出一系列的功输出(WO)和心率(HR)。受试者在每个强度水平使用15分制来表明他们对用力程度的感知。在第二次试验(产生)中,7至14天后,要求受试者产生对应于五个RPE水平的运动强度:15、11、17、13和19。数据分析显示,在估计试验期间,HR与RPE之间(r = 0.95,P < 0.01)以及WO与RPE之间(r = 0.96,P < 0.01)具有高皮尔逊相关系数。此外,在估计试验和产生试验之间,HR(r = 0.82)和WO(r = 0.84)获得了显著相关性(P < 0.01)。事后方差分析显示,在五个强度水平中的三个(RPE 15、17和19),观察到的平均HR差异不显著(P > 0.05),但在两个最低的RPE水平(11和13)差异显著。除了RPE 17外,在所有其他RPE水平上,WO均存在显著的平均差异。这些数据支持了RPE量表作为竞技男性划船运动员生理应激指标的有效性,并为将其用作调节划船测力试验强度的方法提供了支持,尤其是在较高强度水平时。
