Researchers investigated whether exercise training programs are effective in adults with severe obesity receiving bariatric surgery. Controlled trials that allocated participants to either a preoperative or postoperative exercise training group or a nonexercise group were systematically identified. Employing random-effects models, meta-analyses were performed. Overall, 22 training programs were evaluated (18 conducted post-bariatric surgery). Findings revealed that not only improvement in physical fitness was brought about by exercise training performed after bariatric surgery but also this intervention resulted in a small additional weight and fat loss and may avert bone loss and weight regain following bariatric surgery.
