BACKGROUND
The public health benefits of physical activity for children are well known including contributions to metabolic and cardiorespiratory health. Along with physical benefits, engaging in physical activity can support the social and emotional health of youth and promote health and well-being into adulthood. This cluster-randomized controlled trial assesses the impact of an after-school curriculum aimed at improving physically active and inclusive play to promote physical, social, and emotional health. A secondary focus is on the implementation (appropriateness, feasibility, fidelity, sustainability) of the curriculum.
METHODS
The PLAYground (Play and Learning Activities for Youth) project utilizes a social-ecological approach, targeting personal, behavioral, and environmental conditions, and Social Cognitive Theory (SCT) to study how a playground curriculum impacts children's health. All elementary schools with an existing after-school program in a large, public school district in Mesa, Arizona will be eligible to participate. Seven schools will be allocated to the intervention arm in year one using random sampling stratified by school-income. In year two, the seven control schools will receive the intervention. Intervention schools will implement the research-based PlayOn!® playground curriculum to promote active and inclusive play. After-school staff will be trained to teach activities that address social and emotional skills (e.g., conflict resolution) through physical activity. Participating students will be trained as peer leaders to extend the playground activities to the recess setting. This trial will assess between-group differences in physical activity, social and emotional health indicators, and number of health and behavior incidents among students attending intervention schools and control schools. Implementation outcomes will also be assessed among program facilitators at each school site.
DISCUSSION
Enhancement of physical activity opportunities at schools has the potential for high impact and reach due to practicality. Enhancements can also improve quality pedagogy and curricula in after-school settings. Results of this project can inform practical strategies to improve existing after-school programs to prepare leaders (adults and children) to facilitate physical activity, positive social interactions, and emotional well-being.

背景
众所周知，体育活动对儿童的公共健康有益，包括对代谢和心肺健康的贡献。除了身体上的好处，参与体育活动可以支持青少年的社会和情感健康，并促进他们成年后的健康和幸福。这项基于群组的随机对照试验评估了一项旨在改善积极参与和包容玩耍的课后课程对促进身体、社会和情感健康的影响。次要重点是课程的实施（适当性、可行性、忠实性、可持续性）。
方法
PLAYground（青少年玩耍和学习活动）项目采用社会生态方法，针对个人、行为和环境条件，以及社会认知理论（SCT），研究操场课程如何影响儿童的健康。亚利桑那州梅萨市一个大型公立学区内所有有现有课后项目的小学都有资格参加。在第一年，将使用随机抽样按学校收入分层，将七所学校分配到干预组。第二年，七所对照学校将接受干预。干预学校将实施基于研究的 PlayOn！®操场课程，以促进积极和包容的玩耍。课后工作人员将接受培训，通过体育活动教授解决社交和情感技能（如冲突解决）的活动。参与的学生将接受培训成为同伴领袖，将操场活动扩展到课间休息时间。这项试验将评估干预学校和对照学校学生的身体活动、社会和情感健康指标以及健康和行为事件数量的组间差异。还将在每个学校地点评估项目促进者的实施结果。
讨论
由于实用性，增强学校的体育活动机会具有很高的影响力和覆盖面。增强还可以提高课后设置中的优质教学法和课程。该项目的结果可以为改善现有课后项目提供实用策略，使领导者（成人和儿童）有能力促进体育活动、积极的社交互动和情绪健康。
