“…However, in the last study mentioned, the implementation of active or passive breaks did not have a significant effect on subjective ratings. Bosch et al (2011) did not observe a significant difference between high and low work pace. Finally, Iridiastadi and Nussbaum (2006) demonstrated that CL and DC had a significant effect on perceived discomfort.…”

“…Our search identified 12 studies on tasks that were simulated in the laboratory (Horton et al, 2012;Gooyers and Stevenson, 2012;Bosch et al, 2011;Keir et al, 2011;Wells et al, 2010;Raina and Dickerson, 2009;Iridiastadi and Nussbaum, 2006;Balci and Aghazadeh, 2004;Gerard et al, 2002;McLean et al, 2001;Mathiassen and Winkel, 1996;Sundelin, 1993) and 2 studies on real-life occupational settings (Bosch et al, 2007;Christensen et al, 2000). In general, the laboratory studies had small-sized sample groups.…”

“…The task characteristics included job rotation in 4 studies (Horton et al, 2012;Gooyers and Stevenson, 2012;Keir et al, 2011;Wells et al, 2010;Raina and Dickerson, 2009) work-rest schemes (or pauses or breaks) schedules in 4 studies (Balci and Aghazadeh, 2004;McLean et al, 2001;Christensen et al, 2000;Sundelin, 1993) and 6 studies investigating the effects of work pace, cycle time, duty cycle and work duration (Gooyers and Stevenson, 2012;Bosch et al, 2011;Bosch et al, 2007;Iridiastadi and Nussbaum, 2006;Gerard et al, 2002;Mathiassen and Winkel, 1996). Only one study did not use electromyography (EMG) as an objective measuring method to assess the development of fatigue (Wells et al, 2010).…”

“…In the seven studies reviewed (see Table 3), one analyzed only the influence of work duration (Bosch et al, 2007) and three studies investigated only the effect of work pace on muscle fatigue and/or muscle activity (Gooyers and Stevenson, 2012;Bosch et al, 2011;Gerard et al, 2002). The remaining articles tested experimental protocols with variation of contraction level (CL), duty cycle (DC), cycle time (Iridiastadi and Nussbaum, 2006) and with variation of working time and work pace simultaneously (Mathiassen and Winkel, 1996).…”

Ergonomic interventions such as increased scheduled breaks or job rotation have been proposed to reduce upper limb muscle fatigue in repetitive low-load work. This review was performed to summarize and analyze the studies investigating the effect of job rotation and work-rest schemes, as well as, work pace, cycle time and duty cycle, on upper limb muscle fatigue. The effects of these work organization factors on subjective fatigue or discomfort were also analyzed. This review was based on relevant articles published in PubMed, Scopus and Web of Science. The studies included in this review were performed in humans and assessed muscle fatigue in upper limbs. 14 articles were included in the systematic review. Few studies were performed in a real work environment and the most common methods used to assess muscle fatigue were surface electromyography (EMG). No consistent results were found related to the effects of job rotation on muscle activity and subjective measurements of fatigue. Rest breaks had some positive effects, particularly in perceived discomfort. The increase in work pace reveals a higher muscular load in specific muscles. The duration of experiments and characteristics of participants appear to be the factors that most have influenced the results. Future research should be focused on the improvement of the experimental protocols and instrumentation, in order to the outcomes represent adequately the actual working conditions. Relevance to industryIntroducing more physical workload variation in low-load repetitive work is considered an effective ergonomic intervention against muscle fatigue and musculoskeletal disorders in industry. Results will be useful to identify the need of future research, which will eventually lead to the adoption of best industrial work practices according to the workers capabilities.

“…Work pace is a relevant occupational factor and a control parameter which has been shown to influence temporal movement strategies during repetitive tasks (Dempsey et al, 2010). Specifically, higher pace has been associated with more variability and errors during repetitive assembly work (Bosch et al, 2011). Gait studies revealed that trunk kinematic variability has the lowest magnitude at preferred speeds compared to lower and higher speeds (Dingwell and Marin, 2006).…”
