Walking Training on Different Slopes for Chronic Obstructive Pulmonary Disease

This trial is testing how different types of walking exercise affect people with chronic obstructive pulmonary disease (COPD). You would participate in an 8-week walking program on a treadmill, where your group walks on either a flat surface, an uphill slope, or a downhill slope. Researchers want to see which type of slope helps patients breathe better, feel stronger, and move around more easily.

People with COPD often struggle with shortness of breath and low exercise capacity, which limits their daily activities. This study explores whether varying the challenge of walking exercise—by using different slopes—might help patients recover better lung function and physical strength than standard flat-ground walking.
