O6.3 Inspiratory Muscle Training

Inspiratory muscle training (IMT), performed in isolation using a threshold loading device or target-flow resistive device at loads equal to or greater than 30% of an individual’s maximum inspiratory pressure generated against an occluded airway (PImax) has been shown to produce short-term gains in inspiratory muscle strength and endurance, reduce dyspnoea, improve functional exercise capacity (6 or 12 minute walk distance) and confer small gains in HRQoL in patients with COPD (Geddes 2008, Gosselink 2011) [evidence level I]. Although IMT used in isolation is beneficial, its added benefit when combined with whole body exercise training in people with COPD is questionable and for this reason IMT is not a replacement for whole body exercise training and is not recommended as a routine component of a pulmonary rehabilitation program (Spruit 2013).
