  1. BMI, body mass index; DAP, diastolic arterial pressure; FEV1, forced expiratory volume in the first second; FEV1/FVC, ratio between FEV1 and FVC; FVC, forced vital capacity; %F, percentage of body fat; SAP, systolic arterial pressure; WC, waist circumference. Values are expressed as the mean ± SD. †Significant difference between non-smokers and active smokers (p = 0.04). *Significant difference between non-smokers and active smokers (p = 0.03). Significance was accepted at p < 0.05.
