课外活动可以提供一种增加小学学龄儿童身体活动（PA）的机制。这项可行性研究的目的是检验由助教实施的 Action 3:30 干预措施是否有望成为提高 5 年级和 6 年级儿童 PA 的方法。在 20 所小学进行了整群随机可行性试验。 10 所学校接受了行动 3:30 干预，10 所学校被分配到控制组。干预措施包括 40 个一小时的课程，每周两次，由助教进行。计算每所学校招募的参与者的比例。计算干预学校的课程授课情况和课程出席率。通过加速度计在基线 (T0)、干预的最后几周 (T1) 和干预结束后四个月 (T2) 评估平日和放学后（下午 3.30 至 8.30）中等到高强度体力 (MVPA)。估计了实施干预措施的成本。五所干预学校举办了全部 40 场预期课程。其余 5 人中，3 人跑了 39 节，1 人跑了 38 节，1 人跑了 29 节。平均出席率为 53%。 T1 工作日 MVPA 的调整后差异为 4.3 分钟（95% CI -2.6 至 11.3）。性别分层分析表明，男孩在 T1 时获得的工作日 MVPA 比对照组多 8.6 分钟（95% CI 2.8 至 14.5），而女孩则没有影响（0.15 分钟，95% CI -9.7 至 10.0）。没有证据表明俱乐部活动结束后参与该计划会增加 MVPA（T2）。这项干预措施的指示性平均成本为每所学校第一年 2,425 英镑或每个参与儿童 81 英镑，此后每所学校 1,461 英镑或每个参与儿童 49 英镑。 Action 3:30 干预措施的效果与之前的体育活动干预措施相当，但进一步分析表明，存在明显的性别差异，对男孩有积极影响，但没有证据表明对女孩有影响。行动 3:30 干预措施前景广阔，但还需要做更多工作来提高干预措施的有效性，特别是对女孩而言。 ISRCTN58502739
Extracurricular programmes could provide a mechanism to increase the physical activity (PA) of primary-school-aged children. The aim of this feasibility study was to examine whether the Action 3:30 intervention, which is delivered by teaching assistants, holds promise as a means of increasing the PA of Year 5 and 6 children. A cluster randomised feasibility trial was conducted in 20 primary schools. Ten schools received the Action 3:30 intervention and 10 schools were allocated to the control arm. The intervention was 40 one-hour sessions, delivered twice a week by teaching assistants. The proportion of participants recruited per school was calculated. Session delivery and session attendance was calculated for intervention schools. Weekday and after-school (3.30 to 8.30 pm) moderate to vigorous intensity physical (MVPA) was assessed by accelerometer at baseline (T0), during the last few weeks of the intervention (T1) and four months after the intervention had ended (T2). The costs of delivering the intervention were estimated. Five intervention schools ran all 40 of the intended sessions. Of the remaining five, three ran 39, one ran 38 and one ran 29 sessions. Mean attendance was 53%. The adjusted difference in weekday MVPA at T1 was 4.3 minutes (95% CI −2.6 to 11.3). Sex-stratified analyses indicated that boys obtained 8.6 more minutes of weekday MVPA than the control group (95% CI 2.8 to 14.5) at T1 with no effect for girls (0.15 minutes, 95% CI −9.7 to 10.0). There was no evidence that participation in the programme increased MVPA once the club sessions ceased (T2). The indicative average cost of this intervention was £2,425 per school or £81 per participating child during its first year and £1,461 per school or £49 per participating child thereafter. The effect of the Action 3:30 intervention was comparable to previous physical activity interventions but further analysis indicated that there was a marked sex difference with a positive impact on boys and no evidence of an effect on girls. The Action 3:30 intervention holds considerable promise but more work is needed to enhance the effectiveness of the intervention, particularly for girls. ISRCTN58502739
