Polygonatum Odoratum Extract Combined With Aerobic Exercise Improves Body Composition, Insulin Resistance, Inflammation and Gut Microbiota-SCFA Profiles in Men With Central Obesity

7 de novembro de 2026 atualizado por: Beijing Sport University

Polygonatum Odoratum Extract Combined With Aerobic Exercise Improves Body Composition, Insulin Resistance, Inflammation and Gut Microbiota-SCFA Profiles in Men With Central Obesity: A Randomized Placebo-Controlled Trial

This is a randomized controlled trial to investigate whether a combination of Polygonatum odoratum extract and aerobic exercise can improve body composition, insulin resistance, and inflammation in men with central obesity. Participants will be randomly assigned to either an intervention group (90 days of supervised aerobic exercise combined with daily Polygonatum odoratum extract supplementation) or a control group (usual lifestyle advice). The investigators will measure changes in body fat percentage, muscle mass, blood glucose, insulin levels, inflammatory markers, gut microbiota, and short-chain fatty acids (SCFAs) before and after the 90-day intervention. The goal is to evaluate whether combining Polygonatum odoratum supplementation with aerobic exercise can improve metabolic health in men with central obesity. Possible benefits include improved body composition and insulin sensitivity, as well as favorable changes in gut microbiota and SCFA profiles. Potential risks may include mild muscle soreness associated with exercise and gastrointestinal discomfort related to the supplement.
