| Abstract | |
Asthma is a disease with a high prevalence leading to important impairment on patients functional status and health and quality of life. Asthma pathophysiology is centered on chronic airway inflammation that associated with a dysfunction in the autonomic nervous system (ANS) increases bronchial hyperactivity and obstruction. In healthy subjects, the physical training can modulate autonomic and immune systems and its regular practice is recommended for asthmatic patients. However, it remains poorly known the effect of the physical training on airway inflammation and autonomic modulation as well as on psychosocial factors and clinical management of asthmatic patients. Objective: To evaluate the effects of an aerobic training program on airway inflammation, ANS and health related quality of life (HRQL) in adult patients with moderate or severe asthma. Methods: Fifty-tree asthmatic adult patients were randomly assigned to either control (CG; n=27) or training groups (TG n=26). Patients in CG (educational program + respiratory exercises) and TG (similar to control group + aerobic training) were followed twice a week during a 3-month period. Maximal aerobic capacity (VO2max), pulmonary function, induced sputum, fractional concentration of exhaled nitric oxide (FeNO), heart rate variability (HRV) and HRQL were evaluated before and after treatment. Asthma symptoms were evaluated monthly. Results: Our results show that patients from the TG presented a decrease on FeNO and number of eosinophils in the induced sputum, a increased on 19 VO2max and a improvement of HRQL and asthma symptoms (p<0.05). No change was observed in lung function and HRV in both groups after treatment. Conclusion: Our results suggest that a physical fitness program can improve aerobic capacity, quality of life and reduce airway inflammation, however without any influence on ANS in asthmatic patients.
