In-Classroom physical activity breaks (IcPAB) are a promising way to promote children’s health behaviors, while contributing to the development of their academic and cognitive ability and health outcomes. Yet the effect of the activity breaks, which are exclusive to classroom settings, are still mixed and unclear. Hence, this review was conducted to identify the characteristics and the effects of IcPAB among primary school children. The review protocol was registered on PROSPERO (CRD42021234192). Following the Cochrane guidelines, PubMed, PsycINFO (ProQuest), MEDLINE (EBSCOhost), Embase/Ovid, SportDISCUS (EBSCOhost), Web of Science, Scopus and Academic Search Premier (EBSCOhost) databases were searched to collect data on randomised control trials without a time restriction. The final database search was conducted on the 8 November 2021. Random effects models were used to calculate the effect sizes. The systematic review identified ten eligible studies, nine of which were also included in the meta-analysis. Few studies used the theoretical frameworks and process evaluations. IcPAB showed mixed effectiveness on academic outcomes: i.e., IcPAB had effects on spelling performance (p < 0.05) and foreign language learning (p < 0.01) but not on mathematics and reading performance. Health behaviors such as moderate-to-vigorous physical activity levels were improved (p < 0.01), but IcPAB did not have an impact on cognition outcomes and health outcomes. Given these mixed results, further research is needed underpinned by strong methodological quality, theoretical underpinnings and reliable process evaluation methods.
课堂内身体活动休息（IcPAB）是促进儿童健康行为的一种有前途的方式，同时有助于提高他们的学业和认知能力以及健康水平。然而，这种仅在课堂环境中进行的活动休息的效果仍然存在差异，并不明确。因此，本综述旨在确定小学儿童课堂内身体活动休息的特点和效果。综述方案已在 PROSPERO（CRD42021234192）上注册。根据 Cochrane 指南，检索了 PubMed、PsycINFO（ProQuest）、MEDLINE（EBSCOhost）、Embase/Ovid、SportDISCUS（EBSCOhost）、Web of Science、Scopus 和 Academic Search Premier（EBSCOhost）数据库，以收集无时间限制的随机对照试验的数据。最终的数据库搜索于 2021 年 11 月 8 日进行。使用随机效应模型计算效应大小。系统综述确定了 10 项符合条件的研究，其中 9 项也纳入了荟萃分析。很少有研究使用理论框架和过程评估。IcPAB 对学业成绩的影响效果不一：即 IcPAB 对拼写成绩（p < 0.05）和外语学习（p < 0.01）有影响，但对数学和阅读成绩没有影响。中等至剧烈体力活动水平等健康行为得到了改善（p < 0.01），但 IcPAB 对认知结果和健康结果没有影响。鉴于这些混合结果，需要进一步研究，这些研究需要有坚实的方法学质量、理论基础和可靠的过程评估方法的支持。
