Abstract

Rationale: Cystic fibrosis (CF) is characterized by progressive, chronic, suppurative, obstructive pulmonary disease, pancreatic failure with poor digestion, poor absorption of food and secondary malnutrition. The severity of lung disease leads these children to experience recurring infection and a progressive loss of lung function, leading to intolerance to aerobic exercise, which is likely related to the mechanisms of lung injury. The aim of the present study was the evaluation of the effects of a physical aerobic training program.
Material and methods: CP was confirmed for all patients by the positive sweat test. The participants were twenty Caucasian children, with a mean age of 13.21 years. Two groups of patients with CF were formed: one group submitted to physical training (G1; n= 10) and one group without physical training G2; n=10). A third group was the control (CG). The experimental protocol consisted of medical history, lung function test, 3-minute step test which were administered during both the evaluation and reevaluation. The program consisted of six weeks of training twice a week. Each training session consisted of walking or running on the treadmill for 30 min at the speed that allowed the child to attain 70% of the maximal heart rate obtained during a baseline stress test for 3 weeks and 80% in the last 6 weeks, under strict medical supervision. HR was continuously monitored.
Results: The G1 showed increase in the steps (79.5 +/- 9.8 to 89.67 +/- 6.1 degrees, p<0,05) and a lower in the Borg Scale. The G2 without physical training (77.2 +/- 14.2 to 77.4+/- 15.2).
Conclusion: The training program improves short-term cardiopulmonary fitness in children with CF.
