Examined the effects of an exercise of moderate intensity (60% of maximal aerobic power) on specific information-processing mechanisms. 22 college students completed 3 10-min exercise bouts on a bicycle ergometer. Concomitantly, Ss performed 6 manual choice-reaction tasks manipulating task variables (signal intensity, stimulus-response compatibility, and time uncertainty) on 2 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. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
