本研究调查了使用Halo Sport器械的经颅直流电刺激（tDCS）对重复短跑骑行能力和认知能力的影响。在这项三盲、随机、假对照研究中，9名身体活动参与者接受安慰剂刺激（假）或真实的刺激（Halo）20分钟。然后参与者在自行车测力计上进行5 × 6 s短跑，其间穿插24 s的主动恢复。峰值和平均功率输出测量每个冲刺。此外，通过刺激前和刺激后的Stroop测试评估反应时间（RT）和准确性（ACC）方面的认知表现。平均功率输出存在显著的相互作用[F（4，32）= 2.98，P = 0.03]。除初始冲刺外，在所有重复冲刺中均观察到主要治疗效应。Halo在一致或不一致条件下均不影响RT，但在不一致条件下增加ACC [F（1，8）= 10.56，P = 0.012]。这些结果表明，带有Halo Sport系统的tDCS能够增强短跑自行车能力和认知表现。
The present study investigated the effects of transcranial direct current stimulation (tDCS) using the Halo Sport device on repeated sprint cycling ability and on cognitive performance. In this triple-blind, randomized, sham-controlled study, nine physically active participants received either a placebo stimulation (Sham) or real stimulation (Halo) for 20 min. Participants then performed 5 × 6-s sprints interspersed with 24 s of active recovery on a cycle ergometer. Peak and mean power output were measured for each sprint. In addition, cognitive performance in terms of reaction time (RT) and accuracy (ACC) was assessed via Stroop test pre- and post-stimulation. There was a significant interaction for mean power output [F(4,32) = 2.98, P = 0.03]. A main treatment effect was observed in all of the repeated sprints apart from the initial one. Halo did not affect RT in either the congruent or incongruent condition but did increase ACC in the incongruent condition [F(1,8) = 10.56, P = 0.012]. These results suggest that tDCS with the Halo Sport system is able to enhance aspects of sprint cycling ability and cognitive performance.
