The aim of this project is to investigate in obese patients the changes induced by bariatric surgery on the various components of the physical condition and their postoperative evolution following an intervention combining a physical activity program (aquabike vs bicycle) with or without protein supplementation.


Physical condition will be evaluated in obese patients before surgery and 1, 4, 6, 12, 18 and 24 months after surgery.

Between 1 and 4 months after surgery, participants will be assigned to one of the postoperative care groups:

  • Control
  • Control + protein supplementation
  • Training in aquabike
  • Training in aquabike + protein supplementation
  • Bicycle training
  • Bicycle training + protein supplementation
