背景体育（PE）可以提供参与日常中等至剧烈体力活动（MVPA）的机会，但许多班级的 MVPA 水平较低。本研究考察了接受 SPARK（儿童运动、游戏和积极娱乐）计划之前和之后中学体育课中的 MVPA。方法 16 所学校参与了这项研究。八所学校的体育教师接受了干预。对所有学校（N = 561）的体育课进行了两年多的观察。分层线性回归模型检查了干预措施对 MVPA 的数量和一致性以及久坐行为的影响。结果观察到的课堂时间平均有 13.7% 用于 MVPA（每节 60 分钟的课程中约 5 分钟），而久坐行为的时间为 27.5%。没有证据表明该课程会导致 MVPA 增加或一致 MVPA，或者减少久坐行为。研究结果还表明，情境因素可能会影响体育运动中的体力活动水平。 结论 SPARK 中学课程的混合评估结果表明，开箱即用的课程在所有情境下都不会产生相同的结果。根据调查结果描述了对学校健康的影响。需要进一步研究以确定增加体育内外青少年 MVPA 的有效策略。
BACKGROUNDPhysical education (PE) can provide opportunities to engage in daily moderate‐to‐vigorous physical activity (MVPA), but MVPA levels in many classes are low. This study examines MVPA during middle school PE lessons before and after receiving the SPARK (Sports, Play, and Active Recreation for Kids) program.METHODSSixteen schools were enrolled in the study. PE teachers at eight schools received the intervention. PE lessons at all schools (N = 561) were observed over 2 years. Hierarchical linear regression models examined the effect of the intervention on the amount and consistency of MVPA and sedentary behavior.RESULTSAn average of 13.7% of observed class time was spent in MVPA (approximately 5 minutes of a 60‐minute class), compared to 27.5% of time spent sedentary. There was no evidence that the curriculum resulted in increased MVPA or consistent MVPA, or that it decreased sedentary behavior. Findings also suggested that contextual factors may contribute to physical activity levels in PE.CONCLUSIONSMixed evaluation findings of the SPARK middle school curriculum demonstrate that an out‐of‐the‐box curriculum does not have the same results in all contexts. Implications for school health are described based upon findings. Further research is needed to identify effective strategies to increase MVPA for adolescents both in and outside of PE.
