Abstract(s)
Muscle fatigue is a complex phenomenon that has been suggested to be an important precursor for work-related upperlimb musculoskeletal disorders. The assembly work is an example of low-moderate intensity work with elevated risk of muscle fatigue development. This review was performed to summarise and analyse the studies that investigated the influence of work requirements on muscle fatigue development in workplaces or experimental setting. This review was based on relevant articles published from 2000 to 2013 in the research platform Web of Knowledge. The studies included in this review were performed in humans and assess peripheral muscle fatigue in upper limbs during occupational activities. The search yielded 103 articles and 10 were included, according to inclusion criteria. Few studies were conducted in real work environment and the most common methods used to assess muscle fatigue were surface electromyography (EMG). The work duration and intensity level were the determinants of muscle fatigue that had more consistent results in terms of EMG- based parameters. In the studies that report subjective measurement of muscle fatigue, the subjective ratings increase. More research is needed to understand the impact of work requirements on muscle fatigue and work-related performance.
