[Perceived exertion during simulated static work].

Abstract

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.
