Effects of Inspiratory Muscle Training on Functional Capacity in Patients With Heart Failure.

"Patients received IMT for 30-minute per day, 3 days per week for 3 weeks using the Threshold Inspiratory Muscle training device (product Phillips). During training, patients were instructed to maintain diaphragmatic breathing, and try to maintain 10-15 breaths, and rested 5-10 between breaths. As soon as the patients managed; they were encouraged to maintain 25-30 breaths at each workload. All patients wore nose-clip during training.~Inspiratory muscle training diaries were checked weekly. The inspiratory load was set at 40%of maximal inspiratory pressure."
