Abstract

Abstract: Objective To explore the relationship between aerobic exercise and cognition of children by Meta-analysis, so as to provide new orientation for researches on this field. Methods Randomized controlled trial studies on aerobic exercise and children's cognition published from January 2011 to December 2021 were retrieved by searching CNKI, Wanfang, VIP, PubMed and Web of Science databases. According to the inclusion and exclusion criteria of the literature, the quality of the literature was evaluated using the PEDro scale. Then literature with high quality was included. Revman5.4 and Stata12 software were used for Meta-analysis of the included literature. Random effect model or fixed effect model were selected according to heterogeneity test results.The SMD value and 95%CI were calculated and publication bias was assessed. Results A total of 2 052 subjects were included in 11 articles, including randomized controlled trials (n=10) and quasi-experimental designs (n=1). Aerobic exercise can significantly improve children's attention (SMD=0.97, 95%CI:0.34 - 1.61, Z=2.99, P=0.003), and inhibition control, the sub-component of executive function (SMD=0.59, 95%CI:0.07 - 1.10, Z=2.51, P=0.01). However, it had no significant influence on working memory and cognition flexibility (P＞0.05). Conclusion Aerobic exercise can significantly improve the cognitive function of children, but it has a selective influence on inhibition control, the sub-component of the execution function.

摘要： 目的运用Meta分析方法探索有氧运动与儿童认知的关系,为有氧运动和儿童认知的关系提供借鉴。方法通过检索中国知网、万方、维普、PubMed以及Web of Science等中英文数据库,筛选2011年1月—2021年12月关于有氧运动与儿童认知的随机对照试验研究。根据文献的纳入和排除标准,纳入较高质量的文献,使用PEDro量表对文献质量进行评估。使用Revman5.4和Stata12软件对纳入文献进行Meta分析,根据异质性检验结果选择随机效应模型或固定效应模型,计算合并SMD和95%CI,评估发表偏倚。结果共纳入11篇文献,包括随机对照试验(n=10)和准实验设计(n=1)两种,共计2 052例被试。有氧运动可以提高儿童的注意(SMD为0.97,95%CI为0.34~1.61,Z分数为2.99,P=0.003),及高级认知执行功能-抑制控制(SMD为0.59,95%CI为0.07~1.10,Z分数为2.51,P=0.01),差异有统计学意义(P<0.05);而对工作记忆和认知灵活性的影响差异无统计学意义(P>0.05)。结论有氧运动可以改善儿童的认知功能,但是对执行功能的子成分-抑制控制功能具有选择性影响。
