What this trial studies

BARIMOV is a prospective cohort study in adult women with obesity planning bariatric surgery. Participants engage in an online sedentary behavior reduction program started about 6 months before surgery, with education and personalized guidance delivered via mobile apps. The study tracks five timepoints: baseline, just-before-surgery reassessment, during surgery for biopsies, and post-surgery follow-ups up to 12 months to examine physical fitness, surgical outcomes, and potential molecular changes in blood and tissues. It also explores how improvements in fitness might influence weight loss and related health factors after surgery. The approach combines behavioral intervention with biological sampling to understand mechanisms behind any observed effects.
