| 摘要
目的：探究不同应用时间窗（在线或离线）的背外侧前额叶皮质（dorsolateral prefrontal cortex， DLPFC）高精度经颅直流电刺激（high definition transcranial direct current stimulation， HD-tDCS）方案对有氧耐力运动表现的影响。
方法：18例受试者需来访3次，以随机顺序接受3种tDCS干预条件（无刺激/在线刺激/离线刺激）。每次接受一种干预条件并完成5km计时赛（time trial， TT）测试。
结果：与无刺激组相比，在线刺激组和离线刺激组的平均功率均增加（P<0.05）、总时间均降低（P<0.05）。离线刺激组在1000—1500m和2500—3000m的平均功率高于在线刺激组（P<0.05）。在线刺激组和离线刺激组在0—2500m的自觉用力程度（rating of perceived exertion， RPE）均低于无刺激组（P<0.05）。不同干预条件对心率和血乳酸等生理指标没有显著影响（P>0.05）。
结论：聚焦双侧DLPFC的在线或离线HD-tDCS刺激方案均可有效改善有氧耐力运动表现并降低努力感知，离线刺激的改善效果略优于在线刺激。 |

| Abstract
Objective： To investigate the effects of high- definition transcranial direct current stimulation （HD-tDCS）targeting the dorsolateral prefrontal cortex （DLPFC）applied at different application time windows （online vs. offline） on aerobic endurance exercise performance.
Method： Eighteen participants completed three experimental sessions in a randomized crossover design, receiving three stimulation conditions: no stimulation, online HD-tDCS (applied during exercise), and offline HD-tDCS (applied prior to exercise). In each session, participants performed a 5km time trial （TT）.
Result： Compared with no-stimulation group， both online and offline HD-tDCS significantly increased mean power output （P<0.05） and reduced total completion time （P<0.05）. The offline stimulation condition demonstrated higher mean power than the online condition during 1000—1500m and 2500—3000m （P<0.05）. Ratings of perceived exertion （RPE） during 0—2500m were lower in both the online and offline stimulation groups compared with no stimulation group （P<0.05）. There was no significant effect of different intervention conditions on physiological indicators, including heart rate and blood lactate （P>0.05）.
Conclusion： Both online or offline HD-tDCS stimulation programs targeting the bilateral DLPFC can effectively improve aerobic endurance exercise performance and reduce effort perception， with offline stimulation slightly better than online stimulation. |
