本研究的主要目的是确定以课堂为基础的运动休息（energizer; Mahar, Kenny, Shields, Scales, & Collins, 2006）对学生在校期间身体活动水平的影响。采用跨一年级（N = 3）和二年级（N = 3）教室的多重基线设计来检验Energizers计划的效果。每间教室大约有15名学生得到了家长的同意。在每个教室的基线和干预阶段之间计算d指数效应量。课堂活动水平随时间变化的图表，并计算每个教室的基线和干预阶段之间的非重叠数据（PND）值的百分比。Energizers计划的实施显著增加了参与者在学校的步数，这些步数是用加速度计活动监测器测量的。此外，参与研究的教师表示，劲量并没有对学术教学时间产生不利影响，并计划在研究结束后继续在课堂上使用劲量活动。
The primary aim of this study was to determine the effects of classroom-based exercise breaks (Energizers; Mahar, Kenny, Shields, Scales, & Collins, 2006) on students' physical activity levels during the school day. A multiple baseline design across first grade (N = 3) and second grade (N = 3) classrooms was used to examine the effects of the Energizers program. Approximately 15 students per classroom had parental consent to participate. D-index effect sizes were calculated between baseline and intervention phases for each classroom. Classroom activity levels were graphed over time, and percentage of nonoverlapping data (PND) values were calculated between baseline and intervention phases for each classroom. Implementation of the Energizers program significantly increased participants' school-based steps, which were measured using accelerometer activity monitors. In addition, participating teachers indicated that Energizers did not adversely affect academic instructional time and planned to continue using Energizers activities in their classrooms beyond the study.
