We tested a low-cost and scalable set of classroom equipment, called Active Classroom Equipment, which was designed to promote physical activity while children learn. We hypothesized the Active Classroom Equipment would be associated with increased physical activity without impairing learning.
Fourteen first-grade students in a public elementary school (7 females, 7 males, aged 6.9 ± (SD) 0.4 years, 24 ± 5.4 kg, BMI 15.8 ± 2.6 kg/m2) used the Active Classroom Equipment for 30 minutes each day throughout the school year. Five-day physical activity was measured using validated triaxial accelerometers at baseline (before the intervention began) and on 4 sequential occasions during the 9-month intervention.
For the baseline period, 5-day physical activity averaged 157 ± 65 AU/min. When the 14 children accessed the Active Classroom Equipment, their mean 5-day physical activity was 229 ± 103 Acceleration Units (AU)/ min (P < .0001). There were sequential increases in physical activity over the 9-month intervention (Quarter 1: 163 ± 94 AU/min, Quarter 2: 227 ± 108 AU/min, Quarter 3: 278 ± 61 AU/min, Quarter 4: 305 ± 65 AU/min). Students' Dynamic Indicators of Basic Early Literacy Skills (DIBELS) scores improved.
Active Classroom Equipment may be one approach to increase physical activity.
我们测试了一套低成本且可扩展的课堂设备,称为主动式课堂设备,其设计目的是在儿童学习时促进身体活动。我们假设主动式课堂设备会在不影响学习的情况下增加身体活动。
一所公立小学的14名一年级学生(7名女生,7名男生,年龄6.9±(标准差)0.4岁,体重24±5.4千克,体重指数15.8±2.6千克/平方米)在整个学年每天使用主动式课堂设备30分钟。在基线期(干预开始前)以及9个月干预期间的4个连续时间点,使用经过验证的三轴加速度计测量5天的身体活动情况。
在基线期,5天的身体活动平均为157±65加速度单位/分钟。当这14名儿童使用主动式课堂设备时,他们5天的平均身体活动为229±1,03加速度单位(AU)/分钟(P<.0001)。在9个月的干预过程中,身体活动呈连续增加趋势(第1季度:163±94 AU/分钟,第2季度:227±1,08 AU/分钟,第3季度:278±61 AU/分钟,第4季度:305±65 AU/分钟)。学生的基本早期读写技能动态指标(DIBELS)分数有所提高。
主动式课堂设备可能是增加身体活动的一种方法。
