Abstract

Transcranial direct current stimulation (tDCS) and high-intensity interval training (HIIT) have been demonstrated to enhance inhibitory control and working memory (WM) performance in healthy adults. However, the potential benefits of combining these two interventions have been rarely explored and remain largely speculative. This study aimed to explore the effects of acute HIIT combined with dual-site tDCS over the dorsolateral prefrontal cortex (DLPFC, F3 and F4) on inhibitory control and WM in healthy young adults. Twenty-five healthy college students (20.5 ± 1.3 years; 11 females) were recruited to complete HIIT + tDCS, HIIT + sham-tDCS, rest + tDCS, and rest + sham-tDCS (CON) sessions in a randomized crossover design. tDCS or sham-tDCS was conducted after completing HIIT or a rest condition of the same duration. The Stroop and 2-back tasks were used to evaluate the influence of this combined intervention on cognitive tasks involving inhibitory control and WM performance in post-trials, respectively. Response times (RTs) of the Stroop task significantly improved in the HIIT + tDCS session compared to the CON session across all conditions (all p values <0.05), in the HIIT + tDCS session compared to the rest + tDCS session in the congruent and neutral conditions (all p values <0.05), in the HIIT + sham-tDCS session compared to the CON session in the congruent and neutral conditions (all p values <0.05), in the HIIT + sham-tDCS session compared to the rest + tDCS session in the congruent condition (p = 0.015). No differences were found between sessions in composite score of RT and accuracy in the Stroop task (all p values >0.05) and in the 2-back task reaction time and accuracy (all p values >0.05). We conclude that acute HIIT combined with tDCS effectively improved inhibitory control but it failed to yield cumulative benefits on inhibitory control and WM in healthy adults. These preliminary findings help to identify beneficial effects of combined interventions on cognitive performance and might guide future research with clinical populations.

高强度间歇训练结合双部位经颅直流电刺激对健康成年人抑制控制和工作记忆的影响。

经颅直流电刺激（tDCS）和高强度间歇训练（HIIT）已被证明能提高健康成年人的抑制控制和工作记忆（WM）能力。然而，人们很少探讨将这两种干预措施结合起来可能带来的益处，在很大程度上仍是一种推测。本研究旨在探索急性 HIIT 与背外侧前额叶皮层（DLPFC，F3 和 F4）双部位 tDCS 相结合对健康年轻人的抑制控制和工作记忆的影响。研究人员招募了 25 名健康大学生（20.5 ± 1.3 岁；11 名女性），采用随机交叉设计完成 HIIT + tDCS、HIIT + 假-tDCS、休息 + tDCS 和休息 + 假-tDCS（CON）训练。实验后分别使用 Stroop 任务和 2-back 任务来评估这种联合干预对涉及抑制控制和 WM 表现的认知任务的影响。在所有条件下，HIIT + tDCS疗程与CON疗程相比，Stroop任务的反应时间（RTs）均有显著改善（所有P值均为0.05），而2-back任务的反应时间和准确性也有显著改善（所有P值均大于0.05）。我们的结论是，急性 HIIT 结合 tDCS 能有效改善健康成年人的抑制控制能力，但未能对抑制控制能力和 WM 产生累积益处。这些初步研究结果有助于确定联合干预对认知能力的有益影响，并可指导未来对临床人群的研究。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
