Abstract
Introduction: Regular physical activity plays an important role in the prevention of low back pain, osteoporosis, cardiovascular disease, obesity, diabetes, cancer, hypertension, depression and early death. Also, work ability is related to the interactions between physical and mental ability, working conditions, employee efficiency, and employee health status. In this research, the relationship between work ability and the level of physical activity is investigated.
Materials & Methods: This study was descriptive-analytical and cross-sectional, which was conducted among 120 office workers and operatives. Physical activity and work ability index were measured using physical activity questionnaire and Iranian version of work ability index. Data analysis was performed using SPSS20 and (P <0.05) was considered significant.
Results: In this study, gardeners and office workers respectively,had the highest and lowest levels of physical activity with the mean of 4206.09 and 3567.58. However, work ability almost was the same in all groups. Also, Pearson correlation coefficient showed that there was no significant relationship between work ability index and physical activity.
Conclusion: According to the results,the work ability index of subjects was good and physical activity was high. Also, there was no significant relationship between work ability index and physical activity, thus making plans to promote the work ability index should be a priority in the intervention program.

Volume 7, Issue 3 (Iranian Journal of Ergonomics 2019)
Abstract

Background and Objectives: Musculoskeletal disorders cause about half of all work-related disease, and are the major cause of loss of time, increased costs, and labor injury. This study aims to evaluate the workload and its association with the prevalence of wrist disorders. It was carried out in the assembly workers of a manufacturing industry.
Methods: This cross-sectional study was conducted among 120 female workers employed. Theit mental workload, physical workload and prevalence of wrist MSDs were evaluated using the NASA-TLX, the OCRA method and the Nordic wrist and hand scan questionnaire respectively.
Results: The NASA-TLX showed that the physical demands and effort with mean scores of 78.79 and 78.37 were respectively the most important subjective mental workload (SMWL) scale. Also The results on the basis of the OCRA risk level showed that the highest right-hand risk was at risk level 3 and the highest left-hand risk was at risk level 1 .The Statistical analysis showed that OCRA risk levels and mean scale physical demands and efforts were significantly higher in those with wrist pain than those without pain (P<0.05).There was a direct correlation between the severity of the wrist pain with the OCRA risk index in both hands (P=0.001) and the total score of NASA (r=0.232, P<0.05).
Conclusion: It was revealed that mental load was high in assembly lines of the manufacturing industry and this result was also confirmed by physical evaluation. This study indicated that overall score of SMWL can affect the incidence of MSDs. That is why mental workload should be considered as a risk factor for MSDs.
