简要总结

This research program aims to comprehensively investigate the clinical, physiological, metabolic, and molecular effects of reducing sedentary behavior in post-bariatric patients. To this aim, we will conduct a crossover trial and a randomized controlled trial. The crossover trial aims to unravel potential mechanisms underlying the metabolic, physiological and molecular effects of breaking up sedentary time with light-intensity physical activity versus carrying out the minimum amount of daily exercise at once and then remaining sedentary versus simply remaining sedentary throughout all sessions, in a well-controlled laboratorial condition. The 4-month parallel-group randomized controlled trials aim to investigate the feasibility and efficacy of a newly developed personalized intervention focused on replacing sedentary time with light- (or very light-) intensity physical activity in these patients. A multitude of gold-standard techniques will be applied to evaluate the effects of the intervention on several outcomes, including sedentary time (primary outcome), physical activity levels, clinical parameters specific to each condition, cardiometabolic risk factors, immune function, and health-related quality of life.
