Respiratory function and inspiratory muscle training for adults with obesity
Official title: Functional Respiratory Tract Dysfunctions in Individuals With Obesity Undergoing Experimental Inspiratory Muscle Training.
Run by Wroclaw University of Health and Sport Sciences · NCT07307417 · Data updated 2026-11-12
This will test whether inspiratory muscle training can improve breathing and lower inflammation in adults aged 30–60 with obesity (BMI ≥30).

Is this trial a fit for you?
✓Likely a 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.
✕Probably 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.

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.
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 gone: 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.
