There seems to be a general consensus among researchers that acute aerobic exercise (exercise hereafter) improves mood, but the neural mechanisms which drive these effects are far from being clear. The current study investigated the cortical connectivity patterns that underlie changes in mood after exercise. Twenty male adults underwent three different experimental protocols that were carefully controlled in terms of underlying metabolism and were administered in a randomized order: moderate-intensity continuous exercise, high-intensity interval exercise, and seated rest condition. Before and after each experimental protocol, we collected data on the participants' mood using the UMACL questionnaire and recorded their resting-state EEG. We focused on the effective connectivity patterns exerted by the dorso-lateral prefrontal cortex (dlPFC) over the temporal region (TMP), as these are important cortical structures involved in shaping mood. The cortical connectivity patterns in the resting-state EEG were evaluated using the directed transfer function (DTF), which is an autoregressive effective connectivity method. The results showed that both moderate-intensity exercise and high-intensity interval exercise improved participants' self-reported mood. Crucially, this improvement was accompanied by stronger influences of dlPFC over TMP. The observed changes in the effective connectivity patterns between dlPFC and TMP might help to better understand the effects of exercise on mood.
似乎研究人员普遍认为，急性有氧运动（以下简称运动）可以改善情绪，但驱动这些效果的神经机制还远未清楚。本研究旨在探讨运动后情绪变化所涉及的皮质连接模式。20 名成年男性接受了三种不同的实验方案，这些方案在代谢方面得到了精心控制，并以随机顺序进行管理：中等强度持续运动、高强度间歇运动和坐姿休息条件。在每个实验方案之前和之后，我们使用 UMACL 问卷收集了参与者的情绪数据，并记录了他们的静息态 EEG。我们专注于背外侧前额叶皮层（dlPFC）对颞区（TMP）施加的有效连接模式，因为这些是参与塑造情绪的重要皮质结构。使用定向传递函数（DTF）评估静息态 EEG 的皮质连接模式，这是一种自回归有效连接方法。结果表明，中等强度运动和高强度间歇运动都能改善参与者的自我报告情绪。至关重要的是，这种改善伴随着 dlPFC 对 TMP 的影响增强。观察到的 dlPFC 和 TMP 之间的有效连接模式变化可能有助于更好地理解运动对情绪的影响。
