The purpose of the present investigation was to determine the reliability of the Borg (RPE) Scale under a variety of experimental conditions. Fourteen sedentary female subjects performed six repeated work tasks (12 in all) distributed over four experimental testing sessions and presented in a randomized order. Work tasks involved treadmill walking and jogging, cycling, and stool stepping. Work loads were presented in progressive (step-wise), oscillating, or single load submaximal intensities. During work, heart rate (HR) was recorded at regular intervals and ratings of perceived exertion (RPE) were elicited either at regular intervals (interval) or only during the final minute of work (terminal). RPE responses were found to be highly reproducible whether interval or terminal. High correlations were also found between interval and terminal RPE responses. RPE demonstrated a strong relationship with HR and work intensity. It was concluded that category ratings of perceived exertion according to the Borg (RPE) Scale offer a sensitive and reliable measure of stress encountered during work.
本研究的目的是确定在各种实验条件下博格（RPE）量表的可靠性。14名久坐不动的女性受试者进行了六项重复的工作任务（共12项），分布在四个实验测试环节中，并以随机顺序呈现。工作任务包括跑步机行走和慢跑、骑自行车以及踩凳子。工作负荷以渐进式（逐步）、振荡式或单一负荷次最大强度呈现。在工作期间，定期记录心率（HR），并定期（间隔）或仅在工作的最后一分钟（末期）获取自觉用力程度（RPE）评分。发现无论间隔还是末期，RPE反应都具有高度可重复性。间隔和末期RPE反应之间也发现了高度相关性。RPE与HR和工作强度呈现出强烈的关系。得出的结论是，根据博格（RPE）量表进行的自觉用力程度分类评分提供了一种对工作期间所遇压力敏感且可靠的测量方法。
