经颅直流电刺激（tDCS）已被用来增强耐力表现，但其确切机制和效果仍不清楚。研究双侧经颅直流电刺激 (tDCS) 对神经肌肉功能和循环任务失败时间 (TTF) 测试的影响。 12 名参与者按随机顺序接受安慰剂 tDCS (SHAM) 或真实 tDCS，其中双侧运动皮层有两个阴极 (CATHODAL) 或两个阳极 (ANODAL)，同侧肩部有相反的电极对。每个会话持续 10 分钟，电流设置为 2mA。在 tDCS 之前和之后进行神经肌肉评估，然后进行循环任务失败时间 (TTF) 测试。测量心率 (HR)、感知用力等级 (RPE)、腿部肌肉疼痛 (PAIN) 和血乳酸积累 B[La−] 以响应自行车 TTF 测试。阳极条件下皮质脊髓兴奋性增加（P < 0.001），而其他神经肌肉参数没有显示任何变化。在 SHAM 和 CATHODAL 条件下神经肌肉参数没有变化。与 CATHODAL 和 SHAM 条件相比，阳极（P = 0.003）中的 TTF 明显更长（分别为 12.61 ± 4.65 分钟；10.61 ± 4.34 分钟；10.21 ± 3.47 分钟），RPE 显着降低，B[La−] 积累显着升高（P < 0.001）。在循环 TTF 测试期间，不同条件下的 HR (P = 0.803) 和 PAIN 没有差异 (P = 0.305)。我们的研究结果表明，使用双侧脑外参考将阳极置于两个运动皮层上的 tDCS 可以提高耐力表现。
Transcranial direct current stimulation (tDCS) has been used to enhance endurance performance but its precise mechanisms and effects remain unknown. To investigate the effect of bilateral tDCS on neuromuscular function and cycling time to task failure (TTF) test. Twelve participants in randomized order received a placebo tDCS (SHAM) or real tDCS with two cathodes (CATHODAL) or two anodes (ANODAL) over bilateral motor cortices and the opposite electrode pair over the ipsilateral shoulders. Each session lasted 10 min and current was set at 2mA. Neuromuscular assessment was performed before and after tDCS and was followed by a cycling time to task failure (TTF) test. Heart rate (HR), ratings of perceived exertion (RPE), leg muscle pain (PAIN) and blood lactate accumulation B[La−] in response to the cycling TTF test were measured. Corticospinal excitability increased in the ANODAL condition (P < 0.001) while none of the other neuromuscular parameters showed any change. Neuromuscular parameters did not change in the SHAM and CATHODAL conditions. TTF was significantly longer in the ANODAL (P = 0.003) compared to CATHODAL and SHAM condition (12.61 ± 4.65 min; 10.61 ± 4.34 min; 10.21 ± 3.47 min respectively), with significantly lower RPE and higher B[La−] accumulation (P < 0.001). No differences were found for HR (P = 0.803) and PAIN between conditions during the cycling TTF test (P = 0.305). Our findings demonstrate that tDCS with the anode over both motor cortices using a bilateral extracephalic reference improved endurance performance.
