The Effect of 6-week Aerobic Exercise on Pulmonary Function and its Relationship with BMI in Sedentary Men Students

The purpose of this study was to evaluate the effect of 6 weeks of aerobic exercise on pulmonary function due to increasingly high and low BMI index in sedentary students. Therefore, 33 healthy male students aged 25±5 years were selected as the sample into two groups: BMI lower (BMI <25) and high BMI (BMI >25) were divided. Both BMI and Spirometric indices were measured and then they did a progressive aerobic exercise, three times a week, respectively. Spirometry test and BMI were measured again after six weeks (indicators of FVC, FEV1). Paires Sample T-test was used to investigate the effect of exercise on pulmonary function within the group. But in order to determine the effect of exercise on pulmonary function in patients with high BMI and low, Independent- Sample T-test was used. Data analysis showed that after 6 weeks of progressive aerobic exercise FVC, FEV1 in both high and low BMI group, there were significant differences (P<0/05). Generally, we can conclude progressive aerobic exercise can have a positive effect on lung function indices.
