Specific Effects of Acute Moderate Exercise on Cognitive Control
Davranche, Karen; McMorris, Terry
Brain and Cognition, v69 n3 p565-570 Apr 2009
The main issue of this study was to determine whether cognitive control is affected by acute moderate exercise. Twelve participants [4 females (VO[subscript 2 max]=42 ml/kg/min) and 8 males (VO[subscript 2 max]=48 ml/kg/min)] performed a Simon task while cycling at a carefully controlled workload intensity corresponding to their individual ventilatory threshold. The distribution-analytical technique and the delta plot analysis [Ridderinkhof, K. R. (2002). Activation and suppression in conflict tasks: Empirical clarification through distributional analyses. In W. Prinz & B. Hommel (Eds.), "Common mechanisms in perception and action. Attention and performance" (Vol. 19, pp. 494-519). Oxford: Oxford University Press.] were used to assess the role of selective response inhibition in resolving response conflict. Results showed that cognitive processes appeared to be differently affected by acute moderate exercise. Reaction time results confirmed that performance is better (faster without change in accuracy) when the cognitive task is performed simultaneously with exercise. Between-trial adjustments (post-conflict and post-error) highlighted that cognitive control adjustments are also fully efficient during exercise. However, the effect of congruency (Simon effect) appeared to be more pronounced during exercise compared to rest which suggests that the response inhibition is deteriorated during exercise. The present findings suggest that acute moderate exercise differently affects some specific aspects of cognitive functions. (Contains 2 tables and 4 figures.)
