RESUMO

Objectives: Regular physical activity in patients with cystic fibrosis (CF) improves aerobic conditioning and delays disease progression, which results in better quality of life. This study evaluated the effect on functional capacity and quality of life of an aerobic physical activity program based on verbal and written guidelines. Methods: This randomized clinical trial used guidelines for physical exercise in a CF center. Patients were assigned to two groups: intervention (G1), with 17 patients; and control (G2), also with 17 patients. Data were collected from October 2010 to October 2011, and the study population comprised children and adolescents with CF aged 7 to 20 years. The intervention consisted of handing out a manual with guidelines for aerobic physical exercises and reinforcing recommendations in contacts by phone every two weeks. Results: Thirty-four patients were included in the study, 20 of whom were boys (58.5%). The groups were similar at baseline. In G1, 6 patients (35.2%) reported practicing physical exercises regularly; mean age was 13.40±2.81 years, mean percent predicted forced expiratory flow at one second (FEV1%) was 95.53±17.94% and mean peak oxygen uptake (VO2peak) relative to body mass was 34.93±9.09 ml/kg-1.min-1. In G2, four patients (23.5%) reported practicing physical exercises regularly. Mean age was 12.76±3.37 years, mean FEV1 was 100.13±21.27% and mean VO2peak was 33.21±8.26 ml/kg-1.min. In G1, there was a significant increase of physical exercise practice as reported by patients after three months of intervention when compared with G2 (p=0.013). No statistically significant differences were found for the other variables. Conclusion: Verbal and written guidelines for aerobic exercise, together with supervision over the phone, had a positive impact on the report of regular physical exercise practice by children and adolescents. However, no improvement was found in physiological parameters or domains of the quality of life questionnaire.
