Abstract
Background: Anti-inflammatory markers play a crucial role in chronic diseases.. Regular training is a valuable method to control inflammation.
Aim: This meta-analysis aims to explore the impact of exercise training on anti-inflammatory indicators like IL-10 and IL-4.
Martials and methods: Various databases, including PubMed, Cochrane, Embase, Web of Science, EBSCO, and Google Scholar, were systematically searched for randomized controlled trials from 2007 to 2023. Studies focusing on IL-10 and IL-4 indicators in individuals undergoing exercise training were selected. According to the study inclusion criteria, ultimately, 40 articles were finally selected as study samples for the meta-analysis. The meta-analysis was conducted using fixed and random effects models to analyze the effect sizes, taking into account factors such as age, gender, health status, type and duration of exercise, and BM..
Results: Aerobic training significantly increased IL-10 levels (p=0.00, 95% CI=0.267:0.723, ES=0.495), while the increase after resistance training was not significant (ES=0.295, 95% CI-0.020:0.610, p=0.067). Both aerobic training (ES=-282, 95% CI=-0.795:0.185, p=0.237) and resistance training (ES=0.227, 95% CI=-0.389:0.843, p=0.471) had no significant effect onIL-4 levels. Subgroup analysis revealed a significant increase in IL-10 associated withBMI subgroups (p=0.019), with the highest increase in BMI group 18 to 25 (p=0.001). Subgroup meta-analysis for IL-4 showed no significant differences between subgroups (p>0.05).
Conclusion: Aerobic training was associated with a significant increase in IL-10 levels in healthy and unhealthy subjects, but aerobic and resistance training had no significant effect on IL-4 levels. Further randomized controlled studies are essential, especially focusing on resistance training and different training scenarios.
