This study is a monocentric longitudinal study conducting in obese patients: candidates to sleeve gastrectomy and these same patients 6 months after.The primary aim of this study is to describe the effects of sleeve gastrectomy on habitual physical activity, physical fitness (cardiorespiratory and muscular fitness) and gait parameters in severely obese patients. Functional capacity will be assessed during a 6-min walk test, habitual physical activity with accelerometers during 7-day recordings in habitual life conditions (Actigraph GT3X® and activPAL®), cardiorespiratory fitness during a maximal exercise test on a cycle ergometer with a direct measure of peakVO2, muscle strength with an isokinetic dynamometer (Contrex®), muscle power and postural stability with force platforms (Kistler® and Satel®) and gait parameters with a gait analysis system (GaitRite®). Fatigue, quality of life and joint pain will be assessed with questionnaires (MFI-20, SF36 and WOMAC, respectively).
This study aims to describe the effects of sleeve gastrectomy, the most commonly performed bariatric procedure worldwide, on functional capacity, habitual physical activity, physical fitness (cardiorespiratory and muscular fitness) and gait parameters in severely obese subjects undergoing bariatric surgery. Functional capacity, physical activity, physical fitness and gait parameters will be objectively assessed and compared among candidates seeking sleeve gastrectomy and 6 months after sleeve gastrectomy.
