Investigating the Role of Physical Activity on Pulmonary Function Among Cement Factory Workers

Introduction: Inhalation of suspended particulates in cement plants is one of the most important risk factors for pulmonary and respiratory problems for workers of these factories. The purpose of this study was to investigate the role of physical activity on pulmonary function among cement factory workers. Methods: This  cross-sectional descriptive-analytical study was conducted among 82 cement factory workers. They were selected based on the available sampling method and volunteers were included in the study. According to Beck questionnaire, 48 people were categorized in the inactive and 34 in the active groups. Pulmonary function indices included VC, FVC, FEV1, FEV1, to FVC ratio. Furthermore, the forced expiratory flow of 25-75% (FEF 25-75%) and Spirometry were used to determine the pulmonary capacity of workers. Independent T-test was applied for comparing the two groups and SPSS software ver. 23 was run for data analysis. Results: The results showed that VC, FEV1 / FVC, and FEF 25–75% indices in the active group were significantly higher than the inactive group (p /0,000) (p≥0.01) (p≥0.03). ). Moreover,  FVC and FEV1 indices in the active group were not significantly different (p≥ 0.18) (p 14 0.14) from the inactive group. Conclusion: Our investigations showed the positive effect of physical activity and exercise on the pulmonary parameters and respiratory function of the cement factory workers. Therefore, these people are recommended to exercise regularly during the week to prevent respiratory and health problems caused by high concentrations of cement dust.
