Introduction: Smoking habit is a global public health problem and its long-term use deteriorates overall health, leading to damage to the cardiorespiratory system and therefore to functional capacity, as well as causing significant psychological effects. Aims: To analyze the impact of smoking on functional aspects (nasal mucociliary transportability, pulmonary function and submaximal functional capacity) evaluating the correlation between these variables; to analyze the acute effects of smoking on the cardiorespiratory kinetics and the subjective perception of symptoms during exercise, addressing the psychological effects caused by smoking cessation and immediate smoking. Methods: Article I: A cross-sectional study with 78 smokers, age between 40 and 60 years old, in which pulmonary function (spirometry), functional capacity (six-minute walk test – 6MWT) and nasal mucociliary transportability (Saccharin Transport Time Test – STT) were evaluated; Manuscript II: Non-COPD smokers were stratified in groups according to their nicotine dependence level as low and high nicotine dependence (LND and HND, respectively), and performed treadmill exercise tests in two conditions: smoking abstinence (control) and immediately after smoking. Results: Article I: The sample presented low pack-years and so low smoking history and normal values for pulmonar function and STT. Submaximal functional capacity were normal and spirometry variables related to the pulmonary function had a positive correlation with 6MWT, while STT did not presente any correlation with 6MWT; Manuscript II: Ventilatory variables were lowest across the last stages for LND control. HR were lower on control days for LND and HND when comparing to smoking days. Dyspnea and leg fatigue presented a significant increase for HND control when comparing to smoking day and the opposite was observed in LND smokers. Conclusion: Light smokers presented normal values for pulmonar function, mucociliary clearance and submaximal functional capacity. Pulmonary function presented positive correlation with functional capacity, however it did not happen with between STT and TC6 in light smokers; Besides that, the perceived symptoms of dyspnea and leg fatigue during exercise were diferente between low and high nicotine dependente smokers, suggesting that smoking may hide the symptoms during exercise in smokers with higher nicotine dependence.
