About this study
Official title: Determination of Factors Influencing the Physical Condition of Obese Patients Following Bariatric Surgery. Randomized Controlled Trial
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.
Read the detailed description
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
- Conditions
- Obese Patients With Bariatric Surgery
- Being tested
- Physical activity program : aquabike, Physical activity program : bicycle, Physical activity program : with protein supplementation, Physical activity program : without protein supplementation

Questions about this trial
What is this clinical trial studying?
A study testing Physical activity program : aquabike, Physical activity program : bicycle and Physical activity program : with protein supplementation in people with Obese Patients With Bariatric Surgery, run by University Hospital, Clermont-Ferrand at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Patrick LACARIN (04 73 75 11 95, placarin@chu-clermontferrand.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Distance traveled at the 6-minute walking test (TM6) (time frame: at 4 months post-surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2018; AzTrials last refreshed its copy on 27 Oct 2026.
