Objectives

To investigate the effect of one bout of moderate-to vigorous-intensity physical activity (MVPA) on executive function in preschoolers, and the moderating effect of children's habitual physical activity (PA) levels.

Method

Based on accelerometer data from three weekdays and one weekend, 63 children aged 3–5 years were divided into tertiles. Children in the upper (n = 21) and lower (n = 20) tertiles participated in an intervention experiment. Using a within-subject design, 41 children participated in 25 min of PA (20 min of MVPA) and a sedentary control condition in random order on 2 separate days. The day–night Stroop, Corsi block, and dimensional change card sort (DCCS) tasks were administered individually in counterbalanced order after completion of each intervention activity. Repeated-measures analysis of variance was used to examine pre–post-test changes in task performance in the high and low PA groups.

Results

Flexibility performance on the DCCS task was temporarily enhanced by one bout of PA in preschoolers [F (1, 39) = 5.95, p = 0.02, η2 = 0.13]. An interaction effect was observed between the habitual PA level and acute PA on cognitive control [F (1, 39) = 5.47, p = 0.03, η2 = 0.12]. The acute PA intervention improved day–night Stroop reaction times in children with high (F = 9.15, p < 0.01), but not low, habitual PA levels (F = 0.10, p = 0.75).

Conclusion

Acute MVPA temporarily improves the cognitive performance of preschoolers, with a greater benefit for children with higher habitual PA levels.

习惯体育活动量高和低的学龄前儿童急性体育锻炼对执行功能的差异作用

目标

调查一轮中度至剧烈运动量(MVPA)对学龄前儿童执行功能的影响,以及儿童习惯性运动量(PA)水平的调节作用。

方法

根据三个工作日和一个周末的加速度计数据,将63位3至5岁的儿童分为三分位数。较高(n  = 21)和较低(n  = 20)的儿童参加了干预实验。采用受试者内部设计,41名儿童在2天中随机参加了25分钟的PA(20分钟的MVPA)和久坐控制条件。完成每个干预活动后,以平衡的顺序分别管理昼夜Stroop,Corsi街区和尺寸变更卡分类(DCCS)任务。重复测量方差分析用于检验高和低PA组的任务绩效的测试前-测试后变化。

结果

在DCCS任务灵活性性能暂时由在学龄前儿童PA中的一个回合[增强˚F(1,39)= 5.95,p  = 0.02,η 2  = 0.13]。惯常PA水平与急性PA对认知控制之间观察到的相互作用效应[ ˚F(1,39)= 5.47,p  = 0.03,η 2  = 0.12]。急性PA干预改善了 习惯性PA水平较高(F  = 9.15,p <0.01)但并非较低的儿童(F  = 0.10,p  = 0.75)的昼夜Stroop反应时间。

结论

急性MVPA暂时改善了学龄前儿童的认知能力,对习惯性PA水平较高的儿童有更大的好处。
