Impact of Physical Activity Levels on Pulmonary Function among Female Office Workers

다국어 초록 (Multilingual Abstract)

Purpose : This study aimed to evaluate the effect of physical activity levels on the pulmonary function of female office workers. Methods : The participants were 27 female office workers from small- and medium-sized enterprises in Seoul.
Physical activity levels were assessed using the international physical activity questionnaire, being calculated as METs.
Pulmonary function was measured using a hand-held spirometer, focusing on the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, and peak expiratory flow (PEF). The Mann–Whitney test was used to compare lung function according to the physical activity level. Correlation and regression analyses were performed to examine the relationship between physical activity levels and pulmonary function. Results : Participants with high physical activity levels demonstrated significantly higher FVC and FEV1 than those with moderate physical activity levels (p<.05). Correlation analysis showed significant associations between physical activity levels and pulmonary function variables (FVC, FEV1, and PEF; p<.05). Simple linear regression analysis revealed that physical activity levels significantly predicted FVC, FEV1, and PEF, explaining approximately 47%, 44.6%, and 16.8% of the variances, respectively. Conclusion : This study reveals that higher physical activity levels positively affect the pulmonary function of office workers. Therefore, promoting physical activity among female office workers is crucial for enhancing pulmonary health.
