Investigation of the Acute Effects of Traditional and Functional IMT on Muscle Oxygenation in COPD

Investigation of the Acute Effects of Traditional and Functional Inspiratory Muscle Training on Muscle Oxygenation in Chronic Obstructive Pulmonary Disease

This study aims to compare the effects of functional and conventional inspiratory muscle training (IMT) on post-exercise muscle deoxygenation in individuals with Chronic Obstructive Pulmonary Disease (COPD). Participants will complete both training modalities on separate days. A 2-minute walk test (2MWT) will be performed baseline, and after each session. Muscle oxygenation (SmO₂) will be assessed using near-infrared spectroscopy . Dyspnea and fatigue will be evaluated with the Modified Borg Scale, and heart rate and oxygen saturation (SpO₂) will be measured by pulse oximetry. Measurements will be recorded before, after training and at the end of the walking test.

Inclusion Criteria:

• Being 18 years of age or older,
• Having a diagnosis of COPD,
• Being in stage II-III according to the GOLD classification,
• Being able to mobilize independently.

Exclusion Criteria:

• Having a recent exacerbation or complication requiring hospitalization,
• Having had a respiratory tract infection within the past month,
• Having any disease or medical condition that prevents participation in exercise, -Having cognitive impairment (a score of <24 on the Mini-Mental Test).
