Effects of anaerobic training in children with cystic fibrosis: a randomized controlled study.
BACKGROUND Children 's physical activity patterns are characterized by short-term anaerobic activities . Anaerobic exercise performance in children with cystic fibrosis ( CF ) has received little attention compared to aerobic performance . This study investigated the effects of anaerobic training in children with CF . DESIGN AND METHODS Twenty patients were r and omly assigned to the training group ( TG ) [ 11 patients ; mean ( + /- SD ) age , 13.6 + /- 1.3 years ; mean FEV(1 ) , 75.2 + /- 20.7 % predicted ] or the control group ( CG ) [ 9 patients ; mean age , 14.2 + /- 2.1 years ; FEV(1 ) , 82.1 + /- 19.1 % predicted ] . The TG trained 2 days per week for 12 weeks , with each session lasting 30 to 45 min . The training program consisted of anaerobic activities lasting 20 to 30 s. The control subjects were asked not to change their normal daily activities . Body composition , pulmonary function , peripheral muscle force , habitual physical activity , aerobic and anaerobic exercise performance , and quality of life were reevaluated at the end of the training program , and again after a 12-week follow-up period . RESULTS Patients in the TG significantly improved their anaerobic performance , aerobic performance , and quality of life . No significant changes were seen in other parameters , and no improvements were found in CG . After the follow-up period , only anaerobic performance and quality of life in TG were significantly higher compared to pretraining values . CONCLUSIONS Anaerobic training has measurable effects on aerobic performance ( although not sustained ) , anaerobic performance , and health-related quality of life in children with CF . Therefore , anaerobic training could be an important component of therapeutic programs for CF patients
