To investigate the relationship between general physical activity level and the cognitive functions of executive control in young adults using behavioral measures and event-related brain potentials.
Forty young adults (mean age=21.1 yrs; 19 females) were differentiated on the basis of their regular physical activity level into two groups: active and sedentary. They performed a spatial priming task consisting of three conditions: control, positive, and negative priming. Spatial priming effects, which are related to executive control and occur automatically, were assessed as indicators of cognitive functioning.
Negative priming effects on reaction time and P3 latency in the active group were larger than in the sedentary group. By contrast, positive priming effects were only observed in the sedentary group.
The cognitive effects of regular physical activity could be observed using a relatively simple paradigm. The results indicate that regular physical activity has a beneficial effect on the cognitive processes on executive control in young adults.
The present study provides additional evidence of the beneficial effects of regular physical activity on cognitive functioning in young adults.
采用行为测量和事件相关脑电位，研究年轻成年人的总体身体活动水平与执行控制认知功能之间的关系。
40名年轻成年人（平均年龄=21.1岁；19名女性）根据其日常身体活动水平分为两组：活跃组和久坐组。他们执行了一项空间启动任务，该任务由三种条件组成：控制、正启动和负启动。与执行控制相关且自动发生的空间启动效应被评估为认知功能的指标。
活跃组对反应时间和P3潜伏期的负启动效应大于久坐组。相比之下，正启动效应仅在久坐组中观察到。
使用相对简单的范式可以观察到规律体育活动的认知效应。结果表明，规律体育活动对年轻成年人执行控制的认知过程有有益影响。
本研究为规律体育活动对年轻成年人认知功能的有益影响提供了更多证据。
