【 摘 要 】

The aim of this study is to investigate the mediation effects of muscle activities on the relationship between production standard time and work productivity. The work productivity and muscle activities data are collected from twenty workers (10 males, 10 females) while performing industrial repetitive tasks at three different levels of production standard time corresponding to "normal", "hard" and 'very hard". Mediation test was performed on the data and the results showed that muscle activities act as a mediator in the relationship between production standard time and work productivity. The result indicates the importance of assessing muscle activities in relation to work productivity at different levels of production standard time in order to optimize work productivity and reduce WMSDs risks.
