We investigated the effect of anodal transcranial direct current stimulation (tDCS) over the right dorsolateral prefrontal cortex (rDLPFC) on the sensitive decision making of female team sports referees. Twenty-four female referees voluntarily participated in this randomized, double-blind, crossover, and sham-controlled study. In three different sessions, participants received either anodal (a-tDCS; anode (+) over F4, cathode (-) over the supraorbital region (SO)), cathodal (c-tDCS; -F4/+SO), or sham tDCS (sh-tDCS) in a randomized and counterbalanced order. a-tDCS and c-tDCS were applied with 2 mA for 20 min. In sh-tDCS, the current was turned off after 30 s. Before and after tDCS, participants performed the computerized Iowa Gambling Task (IGT) and Go/No Go impulsivity (IMP) tests. Only a-tDCS improved IGT and IMP scores from pre to post. The delta (Δ = post-pre) analysis showed a significantly higher ΔIGT in a-tDCS compared to c-tDCS ( = 0.02). The ΔIMP was also significantly higher in a-tDCS compared to sh-tDCS ( = 0.01). Finally, the reaction time decreased significantly more in a-tDCS ( = 0.02) and sh-tDCS ( = 0.03) than in c-tDCS. The results suggest that the a-tDCS improved factors related to sensitive decision making in female team sports referees. a-tDCS might be used as an ergogenic aid to enhance decision performance in female team sports referees.
我们研究了经颅直流电刺激阳极（tDCS）作用于右侧背外侧前额叶皮层（rDLPFC）对女性团队运动裁判员敏感性决策的影响。24名女性裁判员自愿参与了这项随机、双盲、交叉和假刺激对照研究。在三个不同的阶段，参与者以随机和平衡的顺序接受阳极（a-tDCS；阳极（+）置于F4，阴极（-）置于眶上区域（SO））、阴极（c-tDCS；-F4/+SO）或假tDCS（sh-tDCS）。a-tDCS和c-tDCS均以2 mA的电流施加20分钟。在sh-tDCS中，电流在30秒后关闭。在tDCS前后，参与者进行了计算机化的爱荷华赌博任务（IGT）和停止信号冲动性（IMP）测试。只有a-tDCS使IGT和IMP分数从术前到术后得到改善。差值（Δ=术后-术前）分析显示，与c-tDCS相比，a-tDCS的ΔIGT显著更高（=0.02）。与sh-tDCS相比，a-tDCS的ΔIMP也显著更高（=0.01）。最后，a-tDCS（=0.02）和sh-tDCS（=0.03）的反应时间比c-tDCS显著下降得更多。结果表明，a-tDCS改善了与女性团队运动裁判员敏感性决策相关的因素。a-tDCS可能作为一种机能增进辅助手段来提高女性团队运动裁判员的决策表现。
