The immediate and short-term after effects of a bout of aerobic exercise on young adults' information processing were investigated. Seventeen participants performed an auditory two-choice reaction time (RT) task before, during, and after 40 min of ergometer cycling. In a separate session, the same sequence of testing was completed while seated on an ergometer without pedalling. Results indicate that exercise (1) improves the speed of reactions by energizing motor outputs; (2) interacts with the arousing effect of a loud auditory signal suggesting a direct link between arousal and activation; (3) gradually reduces RT and peaks between 15 and 20 min; (4) effects on RT disappear very quickly after exercise cessation; and (5) effects on motor processes cannot be explained by increases in body temperature caused by exercise. Taken together, these results support a selective influence of acute aerobic exercise on motor adjustment stage.
研究了一轮有氧运动对年轻人信息处理的即时和短期后续影响。17名参与者在测力计骑行40分钟之前、期间和之后进行了听觉二选一反应时（RT）任务。在另一次测试中，坐在测力计上不踩踏板的情况下完成了相同的测试序列。结果表明，运动（1）通过激发运动输出提高反应速度；（2）与响亮听觉信号的唤醒作用相互作用，表明唤醒与激活之间存在直接联系；（3）逐渐缩短反应时，并在15至20分钟之间达到峰值；（4）运动停止后对反应时的影响很快消失；（5）对运动过程的影响不能用运动引起的体温升高来解释。综上所述，这些结果支持急性有氧运动对运动调整阶段的选择性影响。
