Respiratory function and inspiratory muscle training for adults with obesity

Functional Respiratory Tract Dysfunctions in Individuals With Obesity Undergoing Experimental Inspiratory Muscle Training.

Not applicable Interventional Wroclaw University of Health and Sport Sciences · NCT07307417

This will test whether inspiratory muscle training can improve breathing and lower inflammation in adults aged 30–60 with obesity (BMI ≥30).

What this trial studies

Adults with obesity will be enrolled at a single center and randomly assigned to receive inspiratory muscle training or a placebo IMT protocol. Respiratory mechanics will be measured using techniques such as the forced oscillation technique, and inflammatory markers will be tracked to link breathing changes with inflammation. Participants with active respiratory disease requiring medication or other major medical exclusions are not eligible. The protocol focuses on supervised, repeated IMT sessions compared with a sham device to determine functional and inflammatory effects.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 30–60 with a BMI of 30 kg/m2 or higher who can attend in-person visits and give informed consent.

Not a fit: People with respiratory diseases that require pharmacological treatment, those with acute illnesses or certain implants (pacemaker, electronic or metal implants), pregnant individuals, or those unable to cooperate are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, IMT could improve respiratory function and reduce inflammation in people with obesity, potentially easing breathlessness and lowering risk of ventilation problems.

How similar studies have performed: Similar inspiratory muscle training approaches have shown improvements in respiratory muscle strength in other populations, but evidence specifically showing reduced inflammation or clear clinical benefit in obesity is limited.
