摘要: 为评价施力作业过程中人员肌肉疲劳状态,建立基于肌力(F)的主观肌肉疲劳评价模型。通过模拟拉车作业试验获得不同时刻拉力值以及手臂和腰部主观肌肉疲劳评分(RPE),归一化处理肌力降幅(FD)值,以消除个体差异;通过相关性分析方法研究肌力降幅归一化值(NFD)与RPE之间的关系;通过回归性分析方法,分别构建以NFD为自变量的手臂与腰部RPE回归方程(即RPE-NFD回归方程),并研究手臂与腰部PRE随时间变化特征。结果表明:RPE与NFD显著线性正相关;RPE-NFD回归方程能够描述施力作业过程中RPE随FD变化的情况;所建评价模型能反映肌肉疲劳随时间发展的特征,并可用以获得作业人员不同施力作业以及不同作业时间下的RPE值。

Abstract: A force (F) based evaluation model for subjective muscular fatigue was developed to explore workers' development of muscular fatigue during force exertion tasks. Firstly, pull strength and RPE for arm and waist over time period were obtained by simulated pulling tasks. Then, FD was normalized to describe the variation among participants. Secondly, the relationship between normalized FD (NFD) and RPE was analyzed by correlation analysis. Lastly, RPE regression equations (RPE-NFD regression equation) using the NFD as independent variable for arm and waist, respectively, were constructed via regression analysis. Also, the change of RPE along with time was analyzed. Results showed that RPE of arm and waist were both positive linear with NFD and that RPE regression equations were reasonable to describe the RPE-NFD relationships during force exertion tasks. Also, the constructed evaluation model of muscular fatigue for force exertion task was capable of showing the development of muscular fatigue. According to this model, RPE over time could be obtained for force exertion tasks .

Key words: muscular fatigue, force exertion task, ratings of perceived exertion(RPE), force decrease(FD), evaluation model
