本文研究了19名健康受试者在下列条件下的主观疲劳感（RPE）与工作时不同生理变量的关系：（1）用自主神经系统阻断剂改变工作时心率（HR）。2)在不同类型的体力劳动和3）之前和之后，8周的体育锻炼期间分别。在大多数工作情况下，人力资源反映了主观经历的身体紧张。然而，HR和RPE之间的这种良好相关性在使用阻断剂的实验期间被改变。因此，心动过速本身并不是运动期间HR设置的主要因素-对于给定的氧摄取水平，手臂工作期间的RPE高于腿部工作期间，以及骑自行车期间与跑步或游泳相比。在这些实验中发现RPE和血乳酸浓度之间有更好的相关性。训练后，并在平行的降低HR在次最大工作负荷，RPE是较低的一个给定水平的摄氧量，但相同的“相对”（百分比的最大）摄氧量。
The relationship between the subjective rating of perceived exertion (RPE) and different physiological variables during work were investigated in 19 healthy subjects under the following conditions: 1) after heart rate (HR) has been experimentally changed during work by the use of autonomic nervous system blocking agents. 2) during different types of physical work and 3) before and after an 8 week period of physical training, respectively. In most work situations, HR mirrors the physical strain subjectively experienced. However, this good correlation between HR and RPE was altered during the experiments with blocking agents. Therefore, a tachycardia as such is not the primary factor in the setting of HR during exercise — RPE was higher for a given level of oxygen uptake during arm work than during leg work, as well as during bicycling compared to running or swimming. A better correlation was found in these experiments between RPE and blood lactate concentration. After training, and in parallel to the decrease in HR at submaximal work loads, RPE was lower for a given level of oxygen uptake, but was the same when related to the “relative” (per cent of maximum) oxygen uptake.
