Exercise program to improve weight, strength, and recovery around bariatric surgery

Impact of a Structured Physical Exercise Program on Body Composition in Morbid Obesity: A Randomized Controlled Trial

Not applicable Interventional Instituto de Investigacion Sanitaria La Fe · NCT06934681

This program will test whether a structured exercise plan supported by telerehabilitation helps adults with severe obesity who are having bariatric surgery lose more body fat and gain more strength than usual care.

What this trial studies

This is a randomized clinical trial that will assign 72 adults with severe obesity to either a structured exercise program (with supervised and home-based sessions delivered partly via telerehabilitation) or to usual care including nutritional counseling. The intervention spans the pre- and post-operative periods around bariatric surgery and includes strength and aerobic training components. Primary outcomes include body fat loss and muscle strength, with secondary measures of body composition, functional capacity, quality of life, cardiorespiratory fitness, and selected genetic and metabolic markers. Participants will be evaluated at scheduled in-person visits at the study sites in Valencia and remotely for telerehabilitation sessions.

Who should consider this trial

Good fit: Adults aged 18–65 with BMI ≥40 (or ≥35 with comorbidities) who are scheduled for bariatric surgery and are medically cleared to participate in an exercise program are ideal candidates.

Not a fit: People with uncontrolled cardiovascular disease, uncontrolled diabetes with severe complications, musculoskeletal or systemic conditions that prevent exercise, recent participation in a structured exercise program, or inability to use telerehabilitation may not benefit or be eligible.

Why it matters

Potential benefit: If successful, the program could help people having bariatric surgery lose more body fat, improve strength and fitness, and recover functional ability more quickly than standard care.

How similar studies have performed: Previous prehabilitation and rehabilitation exercise programs around bariatric surgery have shown improvements in fitness and body composition, but telerehabilitation delivery has been less extensively tested and evidence is still limited.
