The interest in the effect of physical activity on children’s brain and cognition has grown in recent years. Preschool period is critical for children’s neuro-cognitive development. However, little is known about the effects of acute exercise on neuro-cognitive function during preschool age. As such, the purpose of this study was to investigate the effect of acute step exercise on preschool children’s neuro-cognition. Twenty preschool children participated and were divided into experimental group and control group (10 children each group). The experimental group completed 10 min of acute step exercise, whilst the control group took a 10 min rest. The reaction time and event-related potential during the Flanker test were recorded before and after the intervention. A series of T-test were employed on the reaction time, N100 latency, N100 amplitude, P300 latency, and P300 amplitude to examine the difference between the two groups. The result indicated that after acute exercise, the P300 latency of experimental group is shorter than that of control group. The findings support the notion that acute exercise has a positive impact on neuro-cognitive function of preschool children.
