The effect of the predominant playing position of elite basketball players on executive functions using both behavioral and electrophysiological measurements was investigated in the present study. Forty-six elite basketball players, including 27 guards and 19 forwards, were recruited. Event-related potential (ERP) signals were simultaneously recorded when the athletes performed the visual Go/NoGo task. Analyses of the results revealed that the guards and forwards groups exhibited comparable behavioral (i.e., reaction time (RTs) and accuracy rates (ARs)) performance. With regards to the electrophysiological indices, the guards relative to the forwards exhibited a shorter N2 latency in the Go condition, a longer N2 latency in the NoGo condition, and a smaller P3 amplitude across the two conditions. These results suggested that although the guards and forwards exhibited similar abilities in terms of behavioral inhibition, different neural processing efficiencies still exist in the basketball playing positions, with guards showing divergent efficiencies in the target evaluation and response selection of the target and non-target stimuli and fewer cognitive resources during premotor preparation and decision-making as compared to the forwards.
本研究通过行为学和电生理学测量方法，探究了精英篮球运动员的主要比赛位置对其执行功能的影响。招募了46名精英篮球运动员，其中包括27名后卫和19名前锋。当运动员执行视觉Go/NoGo任务时，同时记录事件相关电位（ERP）信号。结果分析显示，后卫组和前锋组在行为表现（即反应时间（RTs）和准确率（ARs））上具有可比性。在电生理指标方面，与前锋相比，后卫在Go条件下N2潜伏期较短，在NoGo条件下N2潜伏期较长，且在两种条件下P3波幅较小。这些结果表明，尽管后卫和前锋在行为抑制能力方面表现相似，但篮球比赛位置仍存在不同的神经加工效率，与前锋相比，后卫在目标和非目标刺激的目标评估和反应选择方面表现出不同的效率，并且在前运动准备和决策过程中认知资源较少。
