What this trial studies
This project aims to evaluate the effects of a structured four-week exercise program on fitness, metabolic rate, and weight in patients preparing for bariatric surgery due to obesity. The study will involve a randomized controlled trial with 48 participants, who will be assigned to either a usual care group or an exercise intervention group. Participants in the intervention group will engage in both supervised and self-led exercise sessions, totaling 14 sessions over the four weeks leading up to their surgery. The study will measure various health metrics before and after the intervention to assess its effectiveness.
Why it matters
Potential benefit: If successful, this program could enhance the fitness and metabolic health of patients before bariatric surgery, potentially leading to better surgical outcomes.
How similar studies have gone: Other studies have shown positive outcomes with preoperative exercise interventions in similar patient populations, suggesting this approach is promising.
