The Interactive effect of 12 weeks of aerobic training and the intake of multivitamin minerals supplementation on indicators of male pulmonary function in the expose of urban polluted air

This study studied the interactive effect of 12 weeks of aerobic training and the intake of multivitamin-mineral supplementation on the indicators of male pulmonary function in the exposure of urban polluted air. 46 subjects, with an average age of 25 ± 1.2, took part voluntarily and were completely satisfied in this quasi-experimental study. They were randomly assigned to 4 groups: supplement and exercise (11 subjects), exercise (N = 11), supplement (N = 12), and control (N = 12). This Aerobic exercise was carried out with the same and increasing practice protocol for the first and second groups (including the first week of 12 minutes running with 60% heart rate up to the 12th week, progressively 30 minutes running with 85% heart rate reserve) and with supplementation of multivitamin - minerals which were taken as one capsule each day for the first and third groups of the research. In addition, the variables, including FEV1, FVC, FVC/FEV1, PEF, and FEF50 were measured once before and after 12 weeks using a spirometry device connected to the computer, and Respiratory symptoms were measured by the Respiratory Standard Questionnaire. After 12 weeks of intervention, there was a significant increase in the level of functional parameters of the lung in the combined and supplementary groups and a significant decrease in the exercise group compared with the before the time of the study (p<0.05). The results showed a significant difference between the groups in the measured variables, which was insignificant between the combined group and the exercise. The study results showed that 12 weeks of aerobic exercise and consumption of multivitamin-mineral supplementation leads to a significant increase in the levels of male pulmonary function in urban polluted air. Therefore, using the same amount of vitamins and necessary minerals is recommended to improve pulmonary function, and in case of shortage, use antioxidant supplements, such as the multivitamin-mineral supplement.
