Sponsor

Enrollment

20 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Chronic Obstructive Pulmonary Disease (COPD)

Summary

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.

Plain Language Summary

Simplified for easier understanding

This study is testing how two types of inspiratory muscle training (IMT) — traditional IMT and functional IMT — affect the amount of oxygen reaching the muscles (muscle oxygenation) in people with moderate to severe COPD (chronic obstructive pulmonary disease). IMT involves breathing exercises to strengthen the muscles used for inhaling. **You may be eligible if...** - You are 18 or older - You have been diagnosed with COPD - Your COPD is classified as stage II or III (moderate to severe) on the GOLD scale - You are able to move around independently **You may NOT be eligible if...** - You have recently had a COPD flare-up or complication requiring a hospital stay - You have had a respiratory tract infection in the past month - You have any medical condition that prevents you from exercising - You have significant cognitive impairment (score below 24 on the Mini-Mental Test) Talk to your doctor to see if this trial is right for you.

Interventions

OTHERTraditional inspiratory muscle training

Traditional inspiratory muscle training is a form of training performed using a resistive breathing device that provides resistance to the muscles involved in inspiration. Inspiratory muscle training will be performed using a portable pressure-threshold device (POWERbreathe Classic IMT - Light Resistance). IMT will be administered in a seated position with upper extremities supported and the upper chest/shoulders relaxed. The training procedure will be explained to each participant and performed for 15 minutes at 40% of the maximal inspiratory pressure (MIP).

OTHERFunctional inspiratory muscle training (IMT)

Functional inspiratory muscle training (IMT) is defined as inspiratory muscle training performed while maintaining core stabilization and postural control. Functional IMT consists of a warm-up period, core exercises, dynamic trunk activation combined with upper extremity movements, postural control exercises, and a cool-down period. The participant performs these exercises simultaneously with inspiratory muscle training.
