Abstract: BACKGROUND: Worksite exercise to promote health is a relatively new concept in the industries of developing countries. OBJECTIVES: The aim of this study was to investigate the first-time feasibilities and effects of worksite exercises on physical capabilities of workers in an industry with limited sport facilities. METHODS: A randomized controlled-study was conducted. Ninety-one female workers were randomly assigned to one of the three study groups: two exercise groups and a control group. The workers in the exercise groups participated in group exercises 3 times per week. Maximal oxygen consumption (VO2max), the level of hand skill, and hand grip strengths of the workers were measured before and after the 8-week intervention. RESULTS: Approximately 75% of the workers (n= 68) completed the study. Adherence was higher in the exercise groups. Overall, no improvement was observed in the control group. VO2max increased in both exercise groups (p< 0.05) but no difference was recorded between the groups. The level of hand skill was the least affected in all groups. Strengthening exercises conducted with elastic bands were superior to the repetitive movements in terms of strength gains. CONCLUSION: Exercises capable of improving physical fitness and strength can be integrated into the usual workflow of an industrial workplace with minimal cost. Ensuring sport facilities and instruments during all working hours may improve adherence to worksite exercises.
