教师们抱怨青少年的注意力越来越不集中，注意力越来越少。运动已被证明对认知表现有积极影响。由于小脑和额叶皮质之间的神经元连接，我们假设认知性能可能会受到双侧协调运动（CE）的影响，并且其对认知的影响在短时间的运动后可能已经可见。115名13-16岁的精英表演学校的健康青少年被随机分配到实验组和对照组，并使用d2测试，注意力和集中力的测试。两组分别在常规学校课程（前测）、10分钟协调运动和正常运动课程（NSL，对照组）后进行d2测试（后测）。运动控制心率（HR）。CE和NSL显著提高了d2-测试从测试前到测试后的表现。方差分析显示，在d2检验中，通过性能相互作用，组（CE，NSL）具有显著性，表明CE的改善高于NSL，两组之间HR无显著差异。CE更有效地完成集中和注意任务。由于两组的HR相同，我们假设运动的协调性可能是造成显著差异的原因。CE可能会导致大脑部分的预激活，这些部分也负责调节注意力等功能。因此，我们的研究结果支持要求更激烈的CE在学校，即使是在精英表演学校。(C)2008爱思唯尔爱尔兰有限公司保留所有权利。
Teachers complain about growing concentration deficits and reduced attention in adolescents. Exercise has been shown to positively affect cognitive performance. Due to the neuronal connection between the cerebellum and the frontal cortex, we hypothesized that cognitive performance might be influenced by bilateral coordinative exercise (CE) and that its effect on cognition might be already visible after short bouts of exercise. One hundred and fifteen healthy adolescents aged 13-16 years of an elite performance school were randomly assigned to an experimental and a control group and tested using the d2-test, a test of attention and concentration. Both groups performed the d2-test after a regular school lesson (pre-test), after 10 min of coordinative exercise and of a normal sport lesson (NSL, control group), respectively (post-test). Exercise was controlled for heart rate (HR). CE and NSL enhanced the d2-test performance from pre- to post-test significantly. ANOVA revealed a significant group (CE, NSL) by performance interaction in the d2-test indicating a higher improvement of CE as compared to NSL HR was not significantly different between the groups. CE was more effective in completing the concentration and attention task. With the HR being the same in both groups we assume that the coordinative character of the exercise might be responsible for the significant differences. CE might lead to a pre-activation of parts of the brain which are also responsible for mediating functions like attention. Thus, our results support the request for more acute CE in schools, even in elite performance schools. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
