The accuracy of regulating exercise intensity by Ratings of Perceived Exertion (RPE) was examined. Subjects underwent 4 production trials, 2 on a treadmill (P1A, P1B) and 2 on a cycle ergometer (P2A, P2B). 9 untrained subjects used only their perceptions of effort to regulate exercise intensity. Target intensity was the RPE equivalent to 60% VO2max. Exercise intensity (VO2) during P1A, P1B, and P2A did not differ from the target, but during P2B was lower than target. During P1A and P1B heart rate did not differ from the target but was lower than target during P2A and P2B. RPE seems a valid means of regulating exercise intensity during repeated bouts of treadmill exercise at 60% VO2max; however, exercise intensity during repeated bouts on the cycle ergometer may be lower than target.
研究了通过主观用力感觉等级（RPE）来调节运动强度的准确性。受试者进行了4次测试，其中2次在跑步机上（P1A、P1B），2次在自行车测力计上（P2A、P2B）。9名未经训练的受试者仅根据自己的用力感觉来调节运动强度。目标强度是相当于60%最大摄氧量的RPE。P1A、P1B和P2A期间的运动强度（最大摄氧量）与目标强度无差异，但P2B期间低于目标强度。P1A和P1B期间心率与目标心率无差异，但P2A和P2B期间低于目标心率。在以60%最大摄氧量进行重复的跑步机运动期间，RPE似乎是调节运动强度的有效方法；然而，在自行车测力计上进行重复运动期间，运动强度可能低于目标强度。
