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.

Conditions

  • Chronic Obstructive Pulmonary Disease (COPD)

Interventions

OTHER

Traditional 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).

OTHER

Functional 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.
