Physical training for cystic fibrosisBradley JM, Moran F

SummaryPhysical training to improve exercise capacity in people with cystic fibrosisThe progress of lung disease in cystic fibrosis leads to abnormal breathing during exercise. This limits people exercising, which in turn affects health and body image. Physical training is designed to improve physical, heart and muscle strength through aerobic and anaerobic activity. Aerobic exercise involves training for a length of time such as distance cycling or running. Anaerobic exercise involves training intensely for a short time such as weight training or sprinting. A lack of regular physical training may lead to more severe lung disease and a reduced ability to perform day-to-day tasks. The side effects of exercise include dehydration, damage to muscles and bone fractures in those with low bone mineral density. This review includes seven studies with 231 participants. Due to different study designs, we were not able to combine any data. Some studies were short-term and did not show differences between treatments. However, it is not likely that training for less than one month would be beneficial. There is some evidence that physical training produces benefits and that these are influenced by the type of training programme. There are not enough studies in this review to compare aerobic training to anaerobic training or to a mixture of these two. The review provides some evidence that the benefits of training are maintained after training has ceased, but it is not clear for how long. Physical training is already part of the care package offered to most people with CF and there is no evidence to discourage this.

April 22. 2002 AbstractBackgroundPhysical training may form an important part of the care package for people with cystic fibrosis. ObjectivesTo determine whether a prescribed regimen of physical training produces improvement or prevents deterioration in physiological and clinical outcomes in cystic fibrosis compared to no training. Search strategyWe searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Date of the most recent search: 28 August 2008. Selection criteriaAll randomised and quasi-randomised controlled clinical trials in which a prescribed regimen of physical training is compared to no physical training in people with cystic fibrosis. Data collection and analysisTwo authors independently selected studies for inclusion, assessed methodological quality and extracted data. Main resultsOf the 26 studies identified, seven studies which included 231 participants, met the inclusion criteria. This review does provide some limited evidence from both short- and long-term studies that aerobic or anaerobic physical training has a positive effect on primary outcomes (exercise capacity, strength and lung function) but improvements are not consistent between studies. Authors' conclusionsConclusions about the efficacy of physical training in cystic fibrosis are limited by the small size, short duration and incomplete reporting of most of the studies included in this review. Physical training is already part of the care package offered to most people with cystic fibrosis and there is a lack of evidence to actively discourage this. The benefits obtained from including physical training in a package of care may be influenced by the type of training programme. Further research is needed to assess comprehensively the benefits of exercise programmes in people with cystic fibrosis and the relative benefits of the addition of aerobic versus anaerobic versus a combination of both types of physical training to the care of people with cystic fibrosis. |
