Football is one of the most played sports in the world and kicking with adequate accuracy increases the likelihood of winning a competition. Although studies with different target-directed movements underline the role of distinctive cortical activity on superior accuracy, little is known about cortical dynamics associated with kicking. Mobile electroencephalography is a popular tool to investigate cortical modulations during movement, however, inherent and artefact-related pitfalls may obscure the reliability of functional sources and their activity. The purpose of this study was therefore to describe consistent cortical dynamics underlying target-directed pass-kicks based on test-retest reliability estimates. Eleven participants performed a target-directed kicking task at two different sessions within one week. Electroencephalography was recorded using a 65-channel mobile system and behavioural data were collected including motion range, acceleration and accuracy performance. Functional sources were identified using independent component analysis and clustered in two steps with the components of first and subsequently both sessions. Reliability estimates of event-related spectral perturbations were computed pixel-wise for participants contributing with components of both sessions. The parieto-occipital and frontal clusters were reproducible for the same majority of the sample at both sessions. Their activity showed consistent alpha desyhronization and theta sychnronisation patterns with substantial reliability estimates revealing visual and attentional demands in different phases of kicking. The findings of our study reveal prominent cortical demands during the execution of a target-directed kick which may be considered in practical implementations and provide promising academic prospects in the comprehension and investigation of cortical activity associated with target-directed movements.

足球是世界上最受欢迎的运动之一，以足够的精度踢球会增加赢得比赛的可能性。尽管针对不同目标导向运动的研究强调了独特的皮质活动对卓越精度的作用，但对于与踢球相关的皮质动力学知之甚少。移动脑电图是研究运动过程中皮质调制的常用工具，然而，固有的和与伪迹相关的陷阱可能会掩盖功能源及其活动的可靠性。因此，本研究的目的是基于重测信度估计来描述目标导向传球踢球背后一致的皮质动力学。11名参与者在一周内的两个不同时间段执行了目标导向的踢球任务。使用65通道移动系统记录脑电图，并收集行为数据，包括运动范围、加速度和准确性表现。使用独立成分分析识别功能源，并分两步进行聚类，第一步和随后的两个时间段的成分都参与聚类。对参与两个时间段成分的参与者逐像素计算事件相关频谱扰动的信度估计。顶枕叶和额叶簇在两个时间段的大多数样本中都是可重复的。它们的活动显示出一致的α去同步化和θ同步化模式，具有较高的信度估计，揭示了踢球不同阶段的视觉和注意力需求。我们的研究结果揭示了在执行目标导向踢球过程中突出的皮质需求，这在实际应用中可能会被考虑，并为理解和研究与目标导向运动相关的皮质活动提供了有前景的学术前景。
