| Popis: | Objective: To evaluate the doseâresponse relationship between smoking load and cardiopulmonary fitness, as measured with cardiopulmonary exercise testing (CPET), in adult smokers free of respiratory diseases. Methods: After a complete clinical evaluation and spirometry, 95 adult smokers (35 men and 60 women) underwent CPET on a treadmill. Results: The physiological responses during CPET showed lower cardiorespiratory fitness levels, regardless of smoking load, with a peak Vâ²O2 lower than 100% of the expected value and a lower maximum heart rate. We observed a significant moderate negative correlation between smoking load and peak Vâ²O2. The smoking load also presented a significant negative correlation with maximum heart rate(r = â0.36; p |
