Abstract

The study aimed to analyze the effect of anodal transcranial direct current stimulation (a-tDCS) over the left dorsolateral prefrontal cortex on soccer athletes’ decision making and visual search behavior. It was a single-blind, randomized, and experimental investigation. The 23 soccer athletes were pair-matched according to decision-making skill and then randomized into two groups: a-tDCS and sham. The decision making (during small-sided game and screen task) and visual search behavior were measured before and after the 8-week intervention. Only the a-tDCS group reduced response time in the decision-making screen task (p < .05). The a-tDCS group showed a higher number of fixations than sham group (p < .05) during the small-sided game. The a-tDCS group showed a lower duration of fixation than sham group (p < .05) during the small-sided game. Our results indicated that using a-tDCS over left dorsolateral prefrontal cortex changed visual search behavior and improved the response time of decision-making skill.

训练前反复使用经颅直流电刺激背外侧前额叶皮层改变足球运动员的视觉搜索和改善决策反应时间

本研究旨在分析经颅直流电刺激(a-tDCS)对足球运动员左背外侧前额叶皮层决策和视觉搜索行为的影响。这是一项单盲、随机、实验性研究。23名足球运动员根据决策能力进行配对，然后随机分为两组:a-tDCS组和sham组。在8周干预前后测量决策(小面游戏和屏幕任务)和视觉搜索行为。只有a-tDCS组减少了决策筛选任务的反应时间(p < 0.05)。在小面游戏中，a- tdcs组的注视次数高于假手术组(p < 0.05)。在小面游戏中，a- tdcs组的固定时间比假手术组短(p < 0.05)。结果表明，在左背外侧前额叶皮层使用a-tDCS可以改变视觉搜索行为，提高决策技能的反应时间。
