摘要/Abstract

摘要： 为了解间歇静态拉力作业中人员肌肉疲劳发展特征及其与连续静态拉力作业肌肉疲劳发展的差异,减少肌肉疲劳累积,降低罹患工作相关肌肉骨骼疾患(WMSDs)风险,设计并开展间歇静态拉力作业试验,招募8名大学男生参与试验,测量不同工休比下不同时刻的肌力(F),并记录主观疲劳评分(RPE),然后运用统计学方法分析F和RPE。研究表明:间歇静态拉力作业不同工休比下F曲线走向基本一致,作业结束时刻F值和RPE值均未见统计学显著性差异;组内不同时刻相同部位以及相同部位不同时刻的一些RPE存在显著差异;间歇静态和连续静态拉力作业肌肉疲劳发展存在显著差异,间歇作业中肌肉疲劳累积显著低于连续作业,可考虑采用本文所研究工休比进行拉力作业工作安排,需人力完成的静态作业宜采用间歇静态施力以减缓肌肉疲劳累积。

Abstract: In order to explore features of the development of muscular fatigue in intermittent static pulling task and the difference between it and continuous static pulling task, and to reduce the accumulation of muscular fatigue and risk of getting work-related musculoskeletal disorders, a pulling task was designed and 8 male college students were recruited to participate in the experiment. Then the force (F) and RPE at different time over different ratio of work and rest were measured and analyzed by statistical method. The results show that F curves were almost the same over experiments with different ratio of work and rest during intermittent static pulling task, that values of F and RPE at the end of each trial show insignificant difference, that remarkable differences were found in some RPE over time period and body parts, that there were distinct differences between intermittent and continuous static pulling task and the accumulation of muscular fatigue in intermittent task was much slower than that of continuous task, that it was suggested that pulling task be arranged according to ratios of work and rest in this study, and that workers should adopt intermittent static force application for man-handling static work to reduce the accumulation of muscular fatigue.

Key words: intermittent static pulling task, muscular fatigue, ratings of perceived exertion(RPE), force, work-related musculoskeletal disorders(WMSDs)
