户外休闲空间有可能增加身体活动。本研究采用准实验评估设计来确定游乐场翻新如何影响儿童的使用和身体活动，以及访问是否与儿童的身体活动水平和家长对游乐场的印象相关。在干预公园和对比公园的改造前后，在两周内每天三个 2 小时的时段内，同时收集关于游乐场游客的公园使用和基于公园的活动的观察数据和拦截访谈。随访时未观察到公园之间使用情况存在明显差异。在干预公园中，男孩的出勤率有所增加，但女孩的出勤率有所下降，尽管这种（不显着）下降不如对比公园那么明显。改造后，公园之间参与 MVPA 的儿童数量没有明显差异（公园和时间之间的交互作用：P = 0.73）。在干预公园，随访时参与 MVPA 的女孩人数显着下降（P = 0.04）。使用情况与家长/看护者对游乐场功能的看法相关，但与身体活动水平无关。在更好地了解影响使用和身体活动行为的因素之前，改造限制了增加身体活动的潜力。
Outdoor recreational spaces have the potential to increase physical activity. This study used a quasi-experimental evaluation design to determine how a playground renovation impacts usage and physical activity of children and whether the visitations correlate with children's physical activity levels and parental impressions of the playground. Observational data and intercept interviews were collected simultaneously on park use and park-based activity among playground visitors at pre- and postrenovation at an intervention and a comparison park during three 2-hour periods each day over two weeks. No detectable difference in use between parks was observed at followup. In the intervention park, attendance increased among boys, but decreased among girls although this (nonsignificant) decline was less marked than in the comparison park. Following renovation, there was no detectable difference between parks in the number of children engaged in MVPA (interaction between park and time: P = 0.73). At the intervention park, there was a significant decline in girls engaging in MVPA at followup (P = 0.04). Usage was correlated with parental/carer perceptions of playground features but not with physical activity levels. Renovations have limited the potential to increase physical activity until factors influencing usage and physical activity behavior are better understood.
