“双减”政策是对宏观社会经济进行的调控，课后服务作为重要的社会工程，对促进社会进步、教育公平、青少年健康成长、核心素养的形成等具有重要的指导意义。运用文献资料法、历史研究法、逻辑分析等方法，对“双减”政策下课后延时体育服务的演进历程、机遇挑战及实现路径进行了分析。研究发现,课后延时体育服务的机遇为：国家政策支持体育类培训开展，为课后延时体育服务提供保障；重塑健康成长教育生态，为课后延时体育服务创造机遇；严禁学科类补课行为，为课后延时体育服务提供支持；学生体质发展切实需求，为课后延时体育服务创造条件。课后延时体育服务的挑战为：校内资源不足制约了课后延时体育服务的普及性；绩效保障不足影响了学校落实课后服务的积极性；管理体系不健全阻碍了社会力量的参与性；校外培训资本化混淆了教育结果的公平性。课后延时体育服务实现路径为：提升课后延时体育服务质量，丰富课后体育服务育人新理念；构建课后延时体育服务体系，明确各级管理职能新举措；引进社会力量参与，促进多元主体协同共育新格局；明确学校育人主体地位，践行五育并举的新航向。
