The purpose of this study was to evaluate the use of the rating of perceived exertion (RPE) as a means of regulating the intensity of exercise during running. The subjects were healthy, relatively fit young adults (16 men and 12 women). Estimates of effort were recorded using the Borg 6-20 Scale whilst the maximal oxygen uptake of the subjects was measured as they ran on an electrically driven treadmill. In a further session, the same subjects were requested to run on the treadmill at constant exercise intensity based on their interpretation of levels 9, 13 and 17 of the Borg Scale. They regulated their running speed and the treadmill gradient but had no knowledge of performance from the equipment display panel. A linear regression analysis was carried out to examine the relationship between heart rate, perceived exertion and relative metabolic demand. This revealed that the rating of perceived exertion was at least as good a predictor of exercise intensity as heart rate in both the graded exercise test and effort production test. The results support the view that RPE may be used to predict relative metabolic demand, especially at higher workloads and could be a useful medium for controlling intensity of effort during vigorous exercise in such subjects.
本研究的目的是评估自觉用力程度（RPE）作为跑步运动强度调节手段的应用情况。受试者为健康、身体状况相对良好的年轻人（16名男性和12名女性）。在受试者在电动跑步机上跑步时，使用Borg 6 - 20量表记录用力程度估计值，同时测量其最大摄氧量。在另一次测试中，要求相同的受试者根据他们对Borg量表9级、13级和17级的理解，以恒定的运动强度在跑步机上跑步。他们调节跑步速度和跑步机坡度，但不知道设备显示屏上的表现数据。进行了线性回归分析，以检验心率、自觉用力程度和相对代谢需求之间的关系。这表明，在分级运动测试和用力产生测试中，自觉用力程度至少与心率一样是运动强度的良好预测指标。结果支持以下观点：RPE可用于预测相对代谢需求，尤其是在较高工作负荷时，并且可能是控制此类受试者剧烈运动时用力强度的有用媒介。
