Inspiratory muscle training for cystic fibrosis

Exercise as medicine – evidence for prescribing exercise as therapy in 26 different chronic diseases

“…Inspiratory muscle training has been suggested as a mode of training to improve the lung function and quality of life of people with cystic fibrosis and a Cochrane study from 2013 evaluated the effect of inspiratory muscle training (Houston et al., ). Eight studies with 180 participants met the review inclusion criteria.…”

Benefits of combining inspiratory muscle with ‘whole muscle’ training in children with cystic fibrosis: a randomised controlled trial

“…It is designed to directly improve the performance of these muscles, which are skeletal in nature and thus trainable 7. The specific training loads to the inspiratory muscles can be applied with either a non-linear resistive device, a threshold or targeted loading device or normocapnic hyperpnoea; and the training regimens vary in terms of intensity and duration or both 8 9. IMT with threshold loading devices involves a series of forced inspirations up to a certain percentage (≥20%) of maximal inspiratory pressure (PI max ) to enhance inspiratory muscle strength; this in turn would theoretically improve pulmonary function and airway clearance in CF patients and ultimately, exercise tolerance 7.…”

Respiratory muscle training improves respiratory muscle endurance but not exercise tolerance in children with cystic fibrosis

“…A recent Cochrane review and meta‐analysis failed to show beneficial effects of respiratory muscle training on exercise tolerance and lung function in cystic fibrosis . However, the few studies included in the meta‐analysis were mostly conducted in middle‐aged populations and there was considerable heterogeneity among the investigated interventions (voluntary eucapnic hyperventilation, resistive loading, threshold loading).…”
