The aim of the present study was to examine the effects of an exercise of moderate intensity (60% of maximal aerobic power) on specific information-processing mechanisms. 22 students completed 3 10-min. exercise bouts on a bicycle ergometer. Concomitantly, participants performed six manual-choice-reaction tasks manipulating task variables (Signal Intensity, Stimulus-Response Compatibility, and Time Uncertainty) on two levels. Reaction tests, randomly ordered, were administered at rest and during exercise. A significant underadditive interaction between Time Uncertainty and exercise was found for the highest quartiles of the distribution of reaction times. No other interaction effects were obtained for the other variables. These results reasonably support that moderate aerobic exercise showed selective rather than general influences on information processing.
本研究的目的是检验中等强度运动（最大有氧能力的60%）对特定信息处理机制的影响。22名学生在自行车测力计上完成了3次10分钟的运动回合。同时，参与者在两个水平上执行六项手动选择反应任务，这些任务操纵任务变量（信号强度、刺激-反应兼容性和时间不确定性）。反应测试随机排序，在休息时和运动期间进行。在反应时间分布的最高四分位数中，发现时间不确定性和运动之间存在显著的次加性相互作用。对于其他变量，未获得其他相互作用效应。这些结果合理地支持了中等强度有氧运动对信息处理显示出选择性而非一般性的影响。
