Acute Mucociliary Clearance Response to Aerobic Exercise in Smokers

摘要: BACKGROUND: Mucociliary clearance is the main defense mechanism of respiratory system, and it influenced by several stimuli, including aerobic exercise cigarette smoking. We evaluated acute response mucociliary to in smokers nonsmokers compared with that found after smoking combined exercise. Also, we investigated whether there was a correlation between autonomic nervous system under these conditions. METHODS: Twenty-one were for saccharin transit time (STT), heart rate variability exercise, followed smoking, rest. For comparison, 17 also assessed during Repeated-measures analysis variance Tukey test or Friedman Dunn used evaluate STT, response, other variables and/or smokers. A paired t Wilcoxon analyze responses nonsmokers. Correlations using Pearson Spearman coefficients. RESULTS: The STT reduced both groups, similar them. Other stimuli STT. showed negative sympathetic activity positive parasympathetic CONCLUSIONS: Although impaired smokers, responded stimulus as demonstrated STTs This correlated groups. In
