本研究评估了急性中度踏车运动对儿童注意认知控制行为和神经电指标的影响，以及对学校学习成绩认知应用方面的影响。受试者内设计包括20名青春期前参与者（年龄= 9.5±0.5岁；8名女性），以评估在修改侧卫任务和大范围成就测试3中运动引起的表现变化。休息阶段包括认知测试，随后是心肺健康评估，以确定有氧健康。锻炼过程包括在电动跑步机上以估计最大心率的60%行走20分钟，然后在心率恢复到运动前水平的10%以内时进行认知测试。结果表明，与休息相比，有氧运动后反应准确性提高，P3振幅增大，学业成绩测试表现更好。总的来说，这些发现表明，单次急性中等强度有氧运动（即步行）可能改善青春期前儿童对注意力的认知控制，并进一步支持将中度急性运动作为提高注意力和学习成绩的一个因素。这些数据表明，单次锻炼会影响支持认知健康的特定潜在过程，可能是整个生命周期有效运作所必需的。
The effect of an acute bout of moderate treadmill walking on behavioral and neuroelectric indices of the cognitive control of attention and applied aspects of cognition involved in school-based academic performance were assessed. A within-subjects design included twenty preadolescent participants (Age = 9.5 ± 0.5 years; 8 female) to assess exercise-induced changes in performance during a modified flanker task and the Wide Range Achievement Test 3. The resting session consisted of cognitive testing followed by a cardiorespiratory fitness assessment to determine aerobic fitness. The exercise session consisted of 20 minutes of walking on a motor-driven treadmill at 60% of estimated maximum heart rate followed by cognitive testing once heart rate returned to within 10% of pre-exercise levels. Results indicated an improvement in response accuracy, larger P3 amplitude, and better performance on the academic achievement test following aerobic exercise relative to the resting session. Collectively, these findings indicate that single, acute bouts of moderately-intense aerobic exercise (i.e., walking) may improve the cognitive control of attention in preadolescent children, and further supports the use of moderate acute exercise as a contributing factor for increasing attention and academic performance. These data suggest that single bouts of exercise affect specific underlying processes that support cognitive health and may be necessary for effective functioning across the lifespan.
