Quantitative electroencephalography (QEEG) was used to investigate the brain activity of Thai professional female soccer team players who exhibit high performance. The QEEGs of 29 players were recorded three times: twice before a competition (once a week) and a week after a competition. The results of the brain topographic map (absolute power) in the alpha frequency band and the brain connectivity (coherence) in the delta frequency bands represented their anxiety and decision-making levels, respectively. These phenomena occurred in the brain activities of the athletes, which could be used to predict their performances during the competition. Moreover, the value of the correlation coefficient between the brain activity ranking and average performance score revealed a moderate to good relationship (r = .586, = .001). These results support the association between brain activity and performance level during competition.
定量脑电图(QEEG)被用于研究表现优异的泰国职业女子足球队队员的大脑活动。对29名队员的QEEG进行了三次记录:比赛前两次(每周一次)以及比赛后一周。阿尔法频段的脑地形图(绝对功率)结果和德尔塔频段的大脑连通性(相干性)结果分别代表了她们的焦虑水平和决策水平。这些现象出现在运动员的大脑活动中,可用于预测她们在比赛中的表现。此外,大脑活动排名与平均表现得分之间的相关系数值显示出中度到良好的关系(r = 0.586,p = 0.001)。这些结果支持了比赛期间大脑活动与表现水平之间的关联。
