Despite findings showing that acute exercise may help enhance emotion regulation, the neurophysiological mechanisms of these effects remain poorly understood. In this study, we examined whether acute exercise influences cognitive emotion regulation, and, in particular, an implicit cognitive reappraisal. Twenty sedentary young women were randomly assigned to either a control group (n = 10) or an exercise group (n = 10). Participants underwent an implicit cognitive reappraisal task twice, before and after the 30-min acute exercise or control, alongside functional near-infrared spectroscopy recordings (NIRS). The left dorsolateral prefrontal cortex (dlPFC) and left orbital frontal cortex (OFC) were activated during implicit cognitive reappraisal at baseline, but only the left dlPFC activation was linked with behavioral performance. Acute exercise enhanced the activation of these regions, reflective of the partial neural bases of implicit cognitive reappraisal, in the left dlPFC and left OFC, but did not alter the behavioral performance. Results also showed that acute exercise moderated the positive effect of left dlPFC activation on implicit cognitive reappraisal performance; specifically, this effect was stronger in the exercise group. In conclusion, the enhanced activation of the left dlPFC by acute exercise and the increased link between behavioral performance and its neural indices may point to acute exercise as a promoter of implicit cognitive reappraisal.
尽管有研究发现急性运动可能有助于增强情绪调节，但这些影响的神经生理机制仍知之甚少。在这项研究中，我们研究了急性运动是否会影响认知情绪调节，特别是内隐认知重评。二十名久坐的年轻女性被随机分配到对照组（n=10）或运动组（n=10）。参与者在急性运动或对照前和后两次进行内隐认知重评任务，同时进行功能近红外光谱记录（NIRS）。在基线时，左背外侧前额叶皮层（dlPFC）和左眶额皮层（OFC）在进行内隐认知重评时被激活，但只有左 dlPFC 的激活与行为表现相关。急性运动增强了这些区域的激活，反映了内隐认知重评的部分神经基础，在左 dlPFC 和左 OFC 中，但并没有改变行为表现。结果还表明，急性运动调节了左 dlPFC 激活对内隐认知重评表现的积极影响；具体来说，这种影响在运动组中更强。总之，急性运动增强了左 dlPFC 的激活，并且行为表现与其神经指标之间的联系增加，这可能表明急性运动促进了内隐认知重评。
