The purpose of this study was to determine the effect of static work on the rating of perceived exertion (RPE). The subject were healthy, relatively fit young adults (16 men). Exercise was performed at 25% MVC both in a commonly-used work posture and in a non-typical working posture (overhead-work). Estimates of effort were recorded using the CR-20-Scale by Borg. A nonparametric analysis was carried out to examine the relationship between the level of static load and RPE. The results show that the level of static load is reflected in the RPE systematically. It is concluded that RPE measurements render possible comparative evaluation of strain by muscular static work demands.
本研究的目的是确定静态工作对主观用力感觉（RPE）的影响。受试者为健康、相对健康的年轻成年人（16名男性）。分别以常用工作姿势和非典型工作姿势（头顶作业），在25%最大随意收缩（MVC）强度下进行运动。使用博格CR-20量表记录用力程度估计值。进行非参数分析以检验静态负荷水平与RPE之间的关系。结果表明，静态负荷水平在RPE中得到系统性反映。得出的结论是，RPE测量使得通过肌肉静态工作需求对劳损进行比较评估成为可能。
