This study assessed the reliability of ratings of perceived exertion (RPE) for the prescription of exercise intensity during cycling. Ten healthy men (21 to 62 years) and six women (25 to 50 years) attended the laboratory four times, 5 to 7 days apart. On the first visit each subject's maximal oxygen uptake was measured and, subsequently, they cycled at constant work rates based on their perception of ratings 9, 13 and 17 of the Borg 6-20 scale by regulating the resistance of the ergometer without reference to the instrument display panel. Analysis of variance revealed no significant between-trial differences with regard to oxygen uptake (VO2) or heart rate for men or women. The relative exercise intensities corresponding to the 3 ratings of exertion did not differ between men and women. Between-trial correlations for VO2 were highest for visits two and three at RPE levels 9 and 13 (r = 0.83 and r = 0.94) and consistently high (r = 0.92 or greater) for the three trials at RPE17. These data suggest that RPE is a useful frame of reference for the regulation of high levels of exercise intensity in healthy men and women. Small amounts of practice with the scale improve its applicability at lower exercise levels.
本研究评估了在骑行运动强度处方中，自感用力度（RPE）评级的可靠性。10名健康男性（21至62岁）和6名女性（25至50岁）分4次到实验室，每次间隔5至7天。首次就诊时测量了每位受试者的最大摄氧量，随后，他们根据自己对Borg 6 - 20量表中9、13和17级的感觉，通过调节测力计阻力来进行恒定功率骑行，而不参考仪器显示屏。方差分析显示，男性或女性在摄氧量（VO2）或心率方面，各次试验之间没有显著差异。男性和女性对应3个用力等级的相对运动强度没有差异。在RPE水平为9和13时，第2次和第3次就诊时VO2的试验间相关性最高（r = 0.83和r = 0.94），在RPE17的3次试验中相关性一直很高（r = 0.92或更高）。这些数据表明，RPE是调节健康男性和女性高水平运动强度的有用参考标准。对该量表进行少量练习可提高其在较低运动水平时的适用性。
