The short-term after effects of a bout of moderate aerobic exercise were hypothesized to facilitate children's executive functioning as measured by a visual task-switching test. Sixty-nine children (mean age=9.2 years) who were overweight and inactive performed a category-decision task before and immediately following a 23-min bout of treadmill walking and, on another session, before and following a nonexercise period. The acute bout of physical activity did not influence the children's global switch cost scores or error rates. Age-related differences in global switch cost scores, but not error scores, were obtained. These results, in concert with several studies conducted with adults, fail to confirm that single bouts of moderately intense physical activity influence mental processes involved in task switching.
有假设认为，一段适度有氧运动的短期后续效应能够促进儿童的执行功能，这是通过一项视觉任务转换测试来衡量的。69名超重且不活跃的儿童（平均年龄=9.2岁）在进行23分钟跑步机步行前后，以及在另一次测试中，在非运动期前后，都完成了一项类别决策任务。这次急性体育活动并未影响儿童的总体转换成本得分或错误率。研究获得了总体转换成本得分方面与年龄相关的差异，但错误得分方面未获得此类差异。这些结果，与针对成年人开展的多项研究结果一致，未能证实单次适度强度的体育活动会影响任务转换所涉及的心理过程。
