The aim of this study was to examine the facilitating effects of physical exercise on the reaction process. Eleven participants with specific expertise in decision-making sports performed a choice reaction time task during moderate sub-maximal exercise (90% of their ventilatory threshold power). Participants were tested at rest and while cycling. During exercise, the participants were faster, without being more variable. We suggest that the effect of exercise on cognitive performance was due to a major generalized improvement of the whole distribution of response time and, although the benefit effect was small, it was consistent throughout the entire range of reaction times.
本研究的目的是检验体育锻炼对反应过程的促进作用。11名在决策类运动方面具有特定专业技能的参与者在中等强度亚最大运动（其通气阈值功率的90%）期间执行了选择反应时任务。参与者在休息时和骑自行车时接受测试。在运动过程中，参与者的反应更快，且反应变异性没有增加。我们认为，运动对认知表现的影响是由于反应时间整体分布的主要普遍改善，尽管益处效应较小，但在整个反应时间范围内是一致的。
