Inspiratory Muscle Training on Exercise Capacity, Dyspnoea and Health Status in Pulmonary Hypertension: A Randomised Controlled Trial.

ABSTRACT:

Background and objective

To evaluate the effects of a high-intensity inspiratory muscle training on respiratory muscle strength, exercise capacity, dyspnoea, and health-related quality of life (HRQL) in patients with pulmonary hypertension (PH).

Methods

Single-blinded, randomised controlled trial 35 women with clinically stable PH (subgroups 1 and 4), functional class II and III, were randomly assigned to a high-intensity inspiratory muscle training (IMT) or sham training. Daily 8-week IMT protocol with 50% (IMT-50%) of maximal inspiratory muscle pressure (PImax) or sham training with a fixed load of 3 cmH₂O (IMT-S). Daily training time consisted of 2 cycles of 30 dynamic inspiratory efforts twice daily, 7 days/week, for 8 weeks using an inspiratory threshold-load
