This study aimed to determine how cognitive control, engaged in a task requiring selective inhibition, is affected by acute steady-state exercise. An adapted version of the Eriksen flanker task, involving three types of trials that varied according to their level of congruency (congruent trials, stimulus-incongruent trials, and response-incongruent trials) was performed during 2 periods of 20-min cycling at a carefully controlled intensity (50% of maximal aerobic power). The results indicated that moderate exercise improves reaction time (RT) performance on the Eriksen flanker task. This facilitating effect appeared to be neither dependent on the nature of the interference (stimulus level conflict vs. response level conflict) nor on the amount of cognitive control engaged in the task (congruent vs. incongruent trials). Distributional RT analyses did not highlight any sign of impairment in the efficiency of cognitive control.
本研究旨在确定在急性稳定状态运动的情况下,参与需要选择性抑制的认知控制任务会受到怎样的影响。在两个 20 分钟的精心控制强度(最大有氧能力的 50%)的自行车骑行期间,进行了一种经过改编的 Eriksen 侧翼任务版本,其中包含三种根据其一致性水平(一致试验、刺激不一致试验和反应不一致试验)而变化的试验类型。结果表明,适度运动可改善 Eriksen 侧翼任务的反应时间(RT)表现。这种促进作用似乎既不依赖于干扰的性质(刺激水平冲突与反应水平冲突),也不依赖于任务中涉及的认知控制量(一致试验与不一致试验)。分布 RT 分析并未突出显示认知控制效率出现任何损害的迹象。
