COPD is a multisystem disease affecting the skeletal muscle both peripheral and respiratory.
Weakness of respiratory muscle in COPD patients leads to hypercapnia, dyspnea, and decreased exercise capacity.
In COPD ; inspiratory muscle traning (IMT) as a monotherapy improves inspiratory muscle strength, exercise, capacity, and decreases dyspnea.
However, the valve of addition of IMT to a general exercise traning program is still questionable.
The aim of this work was to evaluate the effectiveness of IMT as a part of exercise traning program in patients with COPD.
