Abstract

The differences in the executive attention network and the related blood oxygen characteristics of the right frontal-parietal network brain area between athletes from interceptive and strategic sport were investigated. Strategic athletes had higher accuracy and longer reaction time (RT) compared with interceptive sports athletes, lower flanker conflict effects on accuracy compared to the other two group. It was accompanied by significant activation of the rdLPFC and the rIFG. Strategic athletes had higher flanker conflict effects on RT compared with interception athletes under the invalid cue condition, which was accompanied by significant activation of the right IFG. The strategic athletes complete the task under the condition of invalid clues indicating top-down control, and which is closely related to the activation of the right frontal-parietal network.

摘要

研究了拦截型和策略型运动员在执行注意力网络和右额顶叶网络脑区相关血氧特征的差异。与拦截型运动员相比，战略型运动员具有更高的准确性和更长的反应时间 (RT)，与其他两组相比，侧翼冲突对准确性的影响较小。它伴随着 rdLPFC 和 rIFG 的显着激活。在无效提示条件下，策略型运动员的侧翼冲突对 RT 的影响高于拦截运动员，同时伴有右侧 IFG 的显着激活。战略运动员在指示自上而下控制的无效线索的情况下完成任务，
