Respiratory muscle training for people after bariatric surgery

Official title: Effects of Respiratory Muscle Training on Cardiovascular, Respiratory, Metabolic and Physical Exercise Capacity Parameters Related to Obesity in Post-bariatric Surgery Patients

Run by University Ramon Llull · NCT07289958 · Data updated 2026-11-12

This study will test whether using an inspiratory muscle training device, alone or together with supervised therapeutic exercise, helps people who recently had bariatric surgery breathe better, sleep better, and improve exercise and metabolic measures.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18–60 who are within one month after bariatric surgery and do not have conditions that contraindicate exercise.

Probably not a fit

Patients with serious heart disease, respiratory conditions that prevent exercise, significant psychiatric disorders, or orthopedic problems limiting physical activity are unlikely to benefit or be eligible.

What this trial studies

This is a 12-week randomized clinical trial in post-bariatric surgery patients that compares inspiratory muscle training (IMT) with a sham device, both alone and combined with institutionalized therapeutic exercise. Participants are randomized into branches comparing exercise+IMT versus exercise+sham, and IMT alone versus sham, to isolate the device's effects and its interaction with supervised exercise. Outcomes measured before and after the program include maximum inspiratory pressure, sleep apnea index and sleep quality, resting heart rate and blood pressure, functional capacity, glycosylated hemoglobin, lipid profile, body composition, and health-related quality of life. The trial is conducted at a hospital site with in-person interventions and follow-up assessments.

Why it matters

Potential benefit: If successful, the intervention could strengthen breathing muscles and lead to improved exercise tolerance, sleep quality, and metabolic and cardiovascular measures after bariatric surgery.

How similar studies have gone: Previous studies have shown that respiratory muscle training can improve respiratory function in obese patients, but its broader effects on metabolic, cardiovascular, and exercise-related outcomes after bariatric surgery remain less well documented.
