Girl Scouts (GS) is a setting with large reach to target increased moderate-to-vigorous physical activity (MVPA) in girls. The Scouting Nutrition and Activity Program (SNAP) increased MVPA during intervention troop meetings; therefore, further examination of implementation of SNAP components is warranted to determine the processes contributing to intervention success. The purpose of this study is to examine variability in implementation of an active recreation (AR) policy into GS troop meetings. Troop leaders (n = 7) were randomized to receive SNAP, an intervention training on implementing a policy promoting AR, or a standard control. Meetings (seven meetings/troop) were observed, and girls in attendance (n = 76, 9-13 years, mean ± SD = 10.51 ± 1.19 years) wore ActiGraph GT1M accelerometers. Two observers attended each meeting and recorded start/stop points of AR time segments, as well as other tasks (i.e., opening/closing, snack, and Girl Scout curriculum [GSC]). Time-segmented accelerometer data were analyzed using Evenson cut points and paired with observation data. Researchers observed 181 segments (mean/day ± SD = 3.77 ± 1.24). Intervention troops implemented more AR segments/day (mean/day = 0.86; 95% CI = 0.62-1.09) than control troops (mean/day = 0.18; 95% CI = 0.00-0.39). A greater percentage of time (%time) was spent in MVPA during AR segments (mean = 10.99; 95% CI = 7.16-14.82) compared with GSC segments (mean = 0.73; 95% CI = 0.00-4.10), opening/closing (mean = 3.96; 95% CI = 0.54-7.38), and snack (mean = 0.74; 95% CI = 0.00-4.10) segments, and during opening/closing segments compared with GSC and snack segments. Intervention troops implemented more AR segments than control troops. Troop meeting patterns of PA were influenced by task. Adding time segments conducive to PA could increase the %time spent in MVPA during GS troop meetings.
女童子军（GS）是一个覆盖面广的组织，可以针对女孩增加中等至剧烈强度的身体活动（MVPA）。童子军营养和活动计划（SNAP）增加了干预性部队会议期间的 MVPA；因此，有必要进一步检查 SNAP 组件的实施情况，以确定有助于干预成功的过程。本研究的目的是检查将积极娱乐（AR）政策纳入 GS 部队会议的实施情况的可变性。部队领导人（n = 7）被随机分为接受 SNAP、实施促进 AR 政策的干预培训或标准对照组。观察了会议（每个部队 7 次会议），并佩戴 ActiGraph GT1M 加速度计的出席女孩（n = 76，9-13 岁，平均值 ± SD = 10.51 ± 1.19 岁）。两名观察员参加了每次会议，并记录了 AR 时间片段的开始/停止点，以及其他任务（即开幕/闭幕、小吃和女童子军课程 [GSC]）。使用 Evenson 切点对时间分段的加速度计数据进行了分析，并与观察数据相关联。研究人员观察了 181 个片段（平均/天 ± SD = 3.77 ± 1.24）。干预部队每天实施的 AR 片段更多（平均/天= 0.86；95%CI = 0.62-1.09）比对照组（平均/天= 0.18；95%CI = 0.00-0.39）。在 AR 片段中花费的时间百分比（%time）更高（平均值= 10.99；95%CI = 7.16-14.82）与 GSC 片段（平均值= 0.73；95%CI = 0.00-4.10）、开幕/闭幕片段（平均值= 3.96；95%CI = 0.54-7.38）和小吃片段（平均值= 0.74；95%CI = 0.00-4.10），开幕/闭幕片段与 GSC 和小吃片段相比。干预部队实施的 AR 片段多于对照组。童子军会议 PA 模式受到任务的影响。增加有利于 PA 的时间片段可以增加 GS 童子军会议期间 MVPA 所占的时间百分比。
