To review the effects of physical activity on health and behavior outcomes and develop evidence-based recommendations for physical activity in youth.
A systematic literature review identified 850 articles; additional papers were identified by the expert panelists. Articles in the identified outcome areas were reviewed, evaluated and summarized by an expert panelist. The strength of the evidence, conclusions, key issues, and gaps in the evidence were abstracted in a standardized format and presented and discussed by panelists and organizational representatives.
Most intervention studies used supervised programs of moderate to vigorous physical activity of 30 to 45 minutes duration 3 to 5 days per week. The panel believed that a greater amount of physical activity would be necessary to achieve similar beneficial effects on health and behavioral outcomes in ordinary daily circumstances (typically intermittent and unsupervised activity).
School-age youth should participate daily in 60 minutes or more of moderate to vigorous physical activity that is developmentally appropriate, enjoyable, and involves a variety of activities.
回顾体育活动对健康和行为结果的影响，并为青少年体育活动制定基于证据的建议。
一项系统的文献综述确定了850篇文章；专家小组成员又确定了其他论文。一名专家小组成员对已确定结果领域的文章进行了审查、评估和总结。证据的强度、结论、关键问题和证据空白以标准化格式提取，并由小组成员和组织代表进行展示和讨论。
大多数干预研究采用每周3至5天、每次持续30至45分钟的中等至剧烈体育活动的监督计划。小组认为，在日常普通情况下（通常是间歇性且无监督的活动），需要更多的体育活动才能对健康和行为结果产生类似的有益影响。
学龄青少年应每天参加60分钟或更长时间的中等至剧烈体育活动，这些活动应适合其发育阶段、有趣且包含各种活动。
