| Introduction: We conducted a systematic review and meta-analysis to examine the effects of exercise training on postprandial glycemia (PPG) and postprandial insulinemia (PPI) in adults with overweight or obesity, including those with cardiometabolic disorders. Methods: A comprehensive literature search was conducted in the PubMed, Web of Science, and Scopus databases up to May 2022 using the keywords “exercise,” “postprandial,” and “randomized controlled trial.” Eligible studies included original research investigating the effects of exercise training on postprandial glycemia (PPG) and/or postprandial insulinemia (PPI) in adults with a body mass index (BMI) ≥ 25 kg/m². Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated using random-effects models to estimate pooled effect sizes and generate forest plots. Additionally, subgroup analyses and meta-regression models were performed to explore the influence of potential categorical and continuous moderators. Results: A total of 29 studies comprising 41 intervention arms and 1,401 participants were included in this systematic review and meta-analysis. Both aerobic training (SMD = –0.32, p = 0.001) and resistance training (SMD = –0.95, p = 0.006) significantly reduced PPG, whereas combined training did not produce a significant effect. Regarding PPI, aerobic training (SMD = –0.39, p = 0.001) was found to be effective, while resistance and combined training showed no significant impact. Conclusion: The findings of the present meta-analysis indicate that aerobic training is an effective intervention for improving postprandial glycemic control in adults with overweight and obesity. These results underscore the potential of regular aerobic exercise as a key strategy for improving metabolic health and reducing cardiometabolic risk in this population. |
