BACKGROUD: The effect of the physical exercise in the workplace (PEW) to health promotion of the worker is contradictory.
OBJECTIVE: to evaluate the effects of the PEW in musculoskeletal disorders (MSDs), perception of stress and quality of life in workers.
METHODS: The participants were divided in two groups: control group (n=46) were included nonparticipants workers of PEW program and PEW group (n=50) were included workers who regularly participate in the exercise program. All workers answered the Nordic general questionnaire, the perceived stress scale and and quality of life questionnaire.
RESULTS: PEW group reported a lower prevalence of MSDs for the trunk in the last seven days and twelve months (p=0.021 and p=0.001, respectively), and for the upper limbs in the last twelve months (p=0.001) compared to the control group . The results for the perception of stress and quality of life showed no significant differences between the groups.
CONCLUSION: PEW is a potential method to reduce the MSDs in workers, but it was not efficient in reducing stress levels or improving the quality of life of the workers.
