Summary

The goal of this clinical trial is to evaluate the impact of supervised training program on body composition, muscular strenght, insulino-resistance profile, heart rate variability and on heart structure and function between 3 to 6 months after mixed bariatric surgery or restrictive bariatric surgery. This study will be conducted in men and women with severe obesity. Respectively for each type of surgery (mixed vs. restrictive), participants will be randomized either to the exercise group or to the control group. For participant randomized in the exercise group, 3 months after the bariatric surgery, they will started a supervised exercise program for 3 months. In contrast, for participant randomized in the control group, they will have consultation with kinesiologist to receive general information about physical activity practice. Each participants will perform 4 evaluations; one before bariatric surgery and 3 after bariatric surgery (3 months, 6 months and 12 months). Thoses evaluations will be assessed at each visit : fasting blood draw, anthropometric measurements, cardiac echocardiography, heart rate variability measurement, mid-thigh and abdominal computed tomography scan, maximal exercise test, six-minute walk test, assessment of lower-limb endurance and strength, assessment of physical activity level and energy expenditure.

12-week supervised exercise program

The exercise program will take place at the Pavillon de Prévention des Maladies Cardiaques, following a personalised exercise program with at least 3 scheduled 60-minute training sessions every week. The ACSM certified kinesiologist in charge of patients will adjust the progression of patients programs on a weekly basis, based on their needs. Length and intensity of training will increase in the first three weeks. The first week will have 20 minutes of cardio (40-60% reserve heart rate) and 10 minutes of muscle training (2 series of 10-15 repetitions). The second week will have a 30 minutes of cardio and 15 minutes of muscle training (2 series of 10-15 repetitions). The third week will have 35 minutes of cardio (50-75% reserve heart rate) and 25 minutes of muscle training (3 series of 10-15 repetitions).
