Exercise to Fight Obesity

Participants will receive the standard intervention provided by the healthcare service, which includes recommendations for physical exercise, physical activity, and healthy eating. This intervention is delivered by the Endocrinology and Nutrition Department at Hospital Universitario y Politécnico La Fe and consists of periodic individual follow-ups (at least three in-person visits per year, both pre- and post-bariatric surgery) by specialized medical staff in Endocrinology and licensed Nutrition and Dietetics professionals. Additionally, it includes five preoperative group sessions focusing on various aspects of healthy nutrition, physical exercise, and physical activity.

Participants will receive the same standard care as the control group, including the same number of visits with the physician and nutritionist and participation in group sessions. Additionally, they will follow a structured physical exercise program, tailored to individual capabilities, combining aerobic and strength exercises, which will primarily be carried out at home with the assistance of telerehabilitation. Physical exercise will be structured in different phases: prior to surgery (prehabilitation), after surgery (rehabilitation), with maintenance periods in between.
