Prebariatric Surgery Physical Activity Program
A study testing Supervised physical activity in people with Obesity, run by Université de Sherbrooke at 1 site in Canada.
Trial summary
Introduction: According to studies, a low physical capacity before surgery is linked with smaller weigh loss after surgery and increases risks of peri-surgical complications. Practice of regular physical activity in obese individuals improves their physical capacity. Read more about this study

About this study
Official title: Effectiveness and Efficacity of Presurgery Supervised Physical Activity Training on Health of Obese Individuals Waiting for Bariatric Surgery
Introduction: According to studies, a low physical capacity before surgery is linked with smaller weigh loss after surgery and increases risks of peri-surgical complications. Practice of regular physical activity in obese individuals improves their physical capacity. No specific recommendation on physical activity prescription is currently available for this reduced fitness population. This project aims to evaluate if a Pre-Surgical Physical Activity Training (PreSPAT) improves physical capacity, surgery effectiveness and decreases peri-surgical complications in morbidly obese individuals.
Methods: This pilot project will be divided in 2 phases:

Phase 1: Ten candidates for bariatric surgery will be included in this phase. In a pre-training focus group, subjects will be interviewed about their expectations and their availability for a PreSPAT. These results combined with those of the literature will be used to design the PreSPAT. To measure its effectiveness, anthropometric parameters, body composition, physical capacity, motivational stage, perceived benefits and barriers facing physical activity and quality of life will be evaluated before and after the PreSPAT. Subjects satisfaction with the physical activity intervention will be measured with a questionnaire at 6 weeks and at the end of the PreSPAT.
Phase 2: 50 candidates for bariatric surgery will be randomized in 2 groups:
Control group: receiving usual care from the integrated medical and surgical treatment obesity clinic of the Centre Hospitalier Universitaire de Sherbrooke, which includes individual counselling by an exercise physiologist every 6 weeks.
Intervention group: will attend for three months before surgery sessions of supervised physical activity as developed during phase 1 in addition to usual care of the integrated medical and surgical treatment obesity clinic.
Physical capacity, anthropometry, body composition, readiness to change, comorbidities, perceived benefits and barriers of physical activity, usual practice of physical activity, quality of life and patient satisfaction with physical activity intervention will be evaluated in the two groups before and after intervention and every 3 months after the surgery during one year. Each occurrence of peri-surgery complications, and the duration of surgery and hospitalization will be recorded.
Impacts: Feasibility and effectiveness of supervised physical activity training will be assessed before the beginning of the randomized controlled study. Phase 2 of the project may generate information that will improve the management of obese candidates for bariatric surgery in order to ensure optimal results for their health. This project will also allow a better understanding of criteria leading to successful surgery and the effects of exercise training in morbidly obese individuals.
Read the detailed description
Introduction: Bariatric surgery appears to be the most effective solution to improve health in morbidly obese individuals. However, this intervention is associated with risks than could be lower with pre-surgery intervention. According to studies, a low physical capacity before surgery is linked with smaller weigh loss after surgery and increases risks of peri-surgical complications. Practice of regular physical activity in obese individuals improves their physical capacity. No specific recommendation on physical activity prescription is currently available for this reduced fitness population. This project aims to evaluate if a Pre-Surgical Physical Activity Training (PreSPAT) improves physical capacity, surgery effectiveness and decreases peri-surgical complications in morbidly obese individuals. Hypotheses: In bariatric surgery patients, the PreSPAT should improve:
- subjects'health (physical capacity, weight, comorbidities, quality of life)
- subjects' motivation to do regular physical activity, their perceived benefits and barriers to do physical activity including pain, discomfort and dyspnea and their satisfaction with their physical activity management
- the duration of surgery and complications
- the postoperative management (duration, complications, re-operation, re-hospitalization). These two last items will probably require a larger population in a future project to complete data if they are conclusive.
Materials and methods: This pilot project will be divided in 2 phases:
Phase 1: Ten candidates for bariatric surgery will be included in this phase. In a pre-training focus group, subjects will be interviewed about their expectations and their availability for a PreSPAT. These results combined with those of the literature will be used to design the PreSPAT. To measure its effectiveness, anthropometric parameters, body composition, physical capacity, motivational stage, perceived benefits and barriers facing physical activity and quality of life will be evaluated before and after the PreSPAT. Subjects satisfaction with the physical activity intervention will be measured with a questionnaire at 6 weeks and at the end of the PreSPAT.
Phase 2: 50 candidates for bariatric surgery will be randomized in 2 groups:
Control group: receiving usual care from the integrated medical and surgical treatment obesity clinic of the Centre Hospitalier Universitaire de Sherbrooke, which includes individual counselling by an exercise physiologist every 6 weeks.
Intervention group: will attend for three months before surgery sessions of supervised physical activity as developed during phase 1 in addition to usual care of the integrated medical and surgical treatment obesity clinic.
Physical capacity, anthropometry, body composition, readiness to change, comorbidities, perceived benefits and barriers of physical activity, usual practice of physical activity, quality of life and patient satisfaction with physical activity intervention will be evaluated in the two groups before and after intervention and every 3 months after the surgery during one year. Each occurrence of peri-surgery complications, and the duration of surgery and hospitalization will be recorded.

Questions about this trial
What is this clinical trial studying?
A study testing Supervised physical activity in people with Obesity, run by Université de Sherbrooke at 1 site in Canada.
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 6 inclusion and 6 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: finished, as of the sponsor's last update on 15 Oct 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 Canada. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in physical fitness 2 weeks before surgery (time frame: 2 weeks before surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01452230, which also lists 2 linked publications.
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 15 Oct 2018; AzTrials last refreshed its copy on 28 Oct 2026.
