Understanding the impacts of the built environment on physical activity (PA) is essential to promoting children's PA. The purpose of this study was to investigate the effects of schoolyard renovations and a PA recess curriculum alone and in combination on children's PA. This was a 2 (learning landscape [LL] vs. non-LL) × 2 (curriculum intervention vs. no curriculum intervention) factorial design with random assignment to the curriculum intervention, and six elementary schools per condition. PA outcomes were assessed preprogram, mid-program, immediate postprogram, and one year postprogram. No meaningful intervention effects were found. Lack of an effect may be due to the brief dose of recess, the curriculum not being integrated within the schoolyard, the LL implementation occurring prior to the study, or the already high levels of PA. Potential avenues to promote PA include making recess longer, integrating recess into the school curricula, and developing recess PA curricula integrating schoolyards.
了解建筑环境对身体活动（PA）的影响对于促进儿童 PA 至关重要。本研究旨在调查单独和结合使用操场改造和 PA 课间休息课程对儿童 PA 的影响。这是一项 2（学习景观[LL]与非 LL）×2（课程干预与无课程干预）的因子设计，随机分配到课程干预组，每组有六所小学。PA 结果在预方案、方案中期、方案即刻后和方案一年后进行评估。没有发现有意义的干预效果。没有效果的原因可能是课间休息时间短，课程没有融入操场，LL 的实施发生在研究之前，或者是 PA 水平已经很高。促进 PA 的潜在途径包括延长课间休息时间、将课间休息时间融入学校课程以及开发融入校园的课间休息 PA 课程。
