Measuring the peak performance of athletes remains a challenge in movement science and sports psychology. Non-invasive quantitative electroencephalography (QEEG) recordings can be used to analyze various factors in sports psychology.
In this context, sports-related psychological factors were used to estimate the performance of Thai professional female soccer players before a competition. The QEEG recordings of thirty-two players were recorded three times: twice before a competition (once a week) and a week after a competition. Four factors of sports psychology were estimated and observed: anxiety, perceptual response to an acute bout of brain activity, assertiveness, and brain central fatigue. A brain topographic map (absolute power) and brain connectivity (coherence and amplitude asymmetry) data were used to analyze sports-related psychological factors. These factors were measurable based on the brain activity of the athletes and could be used to evaluate their performance during competitions by using QEEG values.
Sports-related psychological performance was estimated by Pearson's correlation coefficients, which revealed that a quick perceptual response to an acute bout of brain activity could predict an athlete's performance during competition ( = .584, = .000). Additionally, Spearman's correlation coefficients were used to estimate athletes performance. The results revealed a strong relationship ( =.634, = .000), which was derived from the summation of anxiety and perceptual response to an acute bout of brain activity.
Consequently, the results of the present study can provide information to help staff coaches to choose the best performing players, representing an alternative method for accurately selecting key players in the competitive sports community.
在运动科学和运动心理学中，测量运动员的最佳表现仍然是一项挑战。无创定量脑电图（QEEG）记录可用于分析运动心理学中的各种因素。
在此背景下，利用与运动相关的心理因素来评估泰国职业女子足球运动员在比赛前的表现。对32名运动员的QEEG记录进行了三次：比赛前两次（每周一次）和比赛后一周。评估并观察了运动心理学的四个因素：焦虑、对急性脑活动发作的感知反应、自信和脑中枢疲劳。使用脑地形图（绝对功率）和脑连接性（相干性和幅度不对称性）数据来分析与运动相关的心理因素。这些因素可以根据运动员的脑活动进行测量，并可通过使用QEEG值来评估他们在比赛中的表现。
通过皮尔逊相关系数估计与运动相关的心理表现，结果表明对急性脑活动发作的快速感知反应可以预测运动员在比赛中的表现（r = .584，p = .000）。此外，使用斯皮尔曼相关系数来估计运动员的表现。结果显示存在很强的相关性（r = .634，p = .000），这是由焦虑和对急性脑活动发作的感知反应的总和得出的。
因此，本研究的结果可以为教练人员提供信息，帮助他们选择表现最佳的球员，这代表了一种在竞技体育界准确选拔关键球员的替代方法。
