Abstract

The aim of this study was to evaluate the effects of an active lifestyle on the respiratory function in healthy smokers (n=14) and non-smokers (n=14) aged 29-41 years. Respiratory function was measured using a spirometric test yielding the following parameters: FVC (forced vital capacity), VC/IVC (slow vital capacity and ventilatory profile), MVV (maximum voluntary ventilation), FEV1 (volume expiredafter 1 s). The subjects' lifestyles were assessed by questionnaire, and answers concerning level of physical activity were translated into a physical activity score using a modification of the Borg scale. Non smoking subjects were closer to the theoretical index of FEV1 provided by the spirometer than smoking subjects. Since FEV1 was markedly associated with body weight (r=0.64, p=0.003), analysis of covariance was used to assess the effect of physical activity on FEV1 using body weight as covariate. We found that physical activity was significantly associated with respiratory function (p
