目的：比较幼儿在体育课、课间休息和运动游戏中不同强度的体力活动水平。方法：参与者是140名一年级和二年级儿童（73名女孩;平均年龄= 7.88岁）。除了每天20分钟的休息时间，参与者每周参加75分钟的体育课和另外75分钟的运动游戏课。采用ActiGraph GTX 3加速度计对3个项目中3个阶段的儿童PA水平进行评估。结果变量为久坐、轻度PA和中度至剧烈PA（MVPA）所用时间的百分比。结果：项目和年级的主效应显著，项目与年级的交互效应显著。具体来说，儿童的MVPA在运动和休息高于体育课。二年级儿童表现出较低的久坐行为和MVPA比一年级儿童在休息时，更少的轻PA比一年级儿童在休息和exergaming;和更少的久坐行为，但更高的MVPA exergaming比一年级儿童。结论：幼儿产生较高的PA水平，在休息和运动相比，体育课。因此，其他以学校为基础的PA计划可以作为一个全面的学校PA计划的重要组成部分。提供了教育工作者和卫生专业人员的影响。
Purpose: To compare young children's different intensity physical activity (PA) levels in physical education, recess and exergaming programs. Methods: Participants were 140 first and second grade children (73 girls; Mean(age) = 7.88 years). Beyond the daily 20-minute recess, participants attended 75-minute weekly physical education classes and another 75-minute weekly exergaming classes. Children's PA levels were assessed by ActiGraph GTX3 accelerometers for 3 sessions in the 3 programs. The outcome variables were percentages of time spent in sedentary, light PA and moderate-to-vigorous PA (MVPA). Results: There were significant main effects for program and grade, and an interaction effect for program by grade. Specifically, children's MVPA in exergaming and recess was higher than in physical education. The 2nd-grade children demonstrated lower sedentary behavior and MVPA than the first-grade children during recess; less light PA in both recess and exergaming than first-grade children; and less sedentary behavior but higher MVPA in exergaming than first-grade children. Conclusions: Young children generated higher PA levels in recess and exergaming as compared with physical education. Hence, other school-based PA programs may serve as essential components of a comprehensive school PA program. Implications are provided for educators and health professionals.
