The school environment is globally recognised as a key setting to promote child and adolescent physical activity. School recess contributes up to 40% of the school day and recommended physical activity levels, providing a critical physical activity promotion opportunity for children and adolescents.
To examine the effectiveness of school recess interventions on children's and adolescents' physical activity (PA) and sedentary behaviour (SED) during this time.
Systematic review and meta-analysis.

Forty-three studies were included in the systematic review, trialling eight different intervention strategies including loose equipment, structured recess, and multicomponent studies. The meta-analysis included 16 studies. Overall, between group mean difference for: (i) time spent in moderate to vigorous-intensity physical activity (MVPA) for randomised controlled trials (RCTs) (n = 6) was 0.18 (95% CI - 0.00 to 0.36) with a marginal significant effect of Z = 1.93 (p = 0.05), (ii) time spent in MVPA for non-RCTs (n = 7) was 0.52 (95% CI - 0.01 to 1.03) with an overall effect of Z = 1.99 (p = 0.05), (iii) time spent in sedentary behaviour for RCTs (n = 3) was - 0.48 (95% CI - 1.38 to 0.43) with an overall effect of Z = 1.03 (p = 0.30). All outcomes had high heterogeneity.
School recess interventions show promise for increasing MVPA. It was difficult to draw strong conclusions due to low study numbers in the meta-analysis and varied intervention designs. Interventions may need to focus on single component strategies (e.g., loose equipment) to improve understanding of outcome effects for future studies.
学校环境被全球公认为促进儿童和青少年身体活动的重要场所。课间休息占学校日的 40%，达到了推荐的身体活动水平，为儿童和青少年提供了一个重要的身体活动促进机会。
研究学校课间休息干预对儿童和青少年在此期间身体活动（PA）和久坐行为（SED）的影响。
系统综述和荟萃分析。
EBSCOhost（学术搜索综合版、教育资源、ERIC、全球健康、MEDLINE 完整版、SPORTDiscus）、Scopus 和 ProQuest 全文电子数据库。
系统综述共纳入 43 项研究，试用了八种不同的干预策略，包括松散设备、结构化课间休息和多组分研究。荟萃分析纳入了 16 项研究。总体而言，随机对照试验（RCT）（n=6）中，（i）中等到剧烈强度身体活动（MVPA）的组间平均差异为 0.18（95%CI -0.00 至 0.36），具有边缘显著的 Z 值为 1.93（p=0.05），（ii）非 RCT 中（n=7）MVPA 时间为 0.52（95%CI -0.01 至 1.03），总效应 Z 值为 1.99（p=0.05），（iii）RCT 中（n=3）久坐行为时间为 -0.48（95%CI -1.38 至 0.43），总效应 Z 值为 1.03（p=0.30）。所有结果均存在高度异质性。
学校课间休息干预措施有望增加 MVPA。由于荟萃分析中的研究数量较少且干预设计多样，因此很难得出强有力的结论。未来的研究可能需要专注于单一的干预策略（例如，松散设备），以提高对结果影响的理解。
