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.

急性有氧运动增强参与塑造情绪的结构之间的皮质连接并改善自我报告的情绪:一项针对年轻男性的脑电图有效连接研究

研究人员似乎普遍认为,急性有氧运动(以下称为锻炼)可以改善情绪,但驱动这些效果的神经机制尚不清楚。目前的研究调查了运动后情绪变化的皮层连接模式。20 名成年男性接受了三种不同的实验方案,这些方案在基础代谢方面受到仔细控制,并以随机顺序进行:中等强度的连续运动、高强度的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 问卷收集参与者情绪的数据并记录他们的静息状态 EEG。我们专注于由背外侧前额叶皮层 (dlPFC) 在颞区 (TMP) 上施加的有效连接模式,因为这些是参与塑造情绪的重要皮层结构。使用定向传递函数 (DTF) 评估静息状态 EEG 中的皮质连接模式,这是一种自回归有效连接方法。结果表明,中等强度的运动和高强度的间歇运动都能改善参与者的自我报告情绪。至关重要的是,这种改进伴随着 dlPFC 对 TMP 的更强影响。观察到的 dlPFC 和 TMP 之间有效连接模式的变化可能有助于更好地了解运动对情绪的影响。使用定向传递函数 (DTF) 评估静息状态 EEG 中的皮质连接模式,这是一种自回归有效连接方法。结果表明,中等强度的运动和高强度的间歇运动都能改善参与者的自我报告情绪。至关重要的是,这种改进伴随着 dlPFC 对 TMP 的更强影响。观察到的 dlPFC 和 TMP 之间有效连接模式的变化可能有助于更好地了解运动对情绪的影响。使用定向传递函数 (DTF) 评估静息状态 EEG 中的皮质连接模式,这是一种自回归有效连接方法。结果表明,中等强度的运动和高强度的间歇运动都能改善参与者的自我报告情绪。至关重要的是,这种改进伴随着 dlPFC 对 TMP 的更强影响。观察到的 dlPFC 和 TMP 之间有效连接模式的变化可能有助于更好地了解运动对情绪的影响。自我报告的心情。至关重要的是,这种改进伴随着 dlPFC 对 TMP 的更强影响。观察到的 dlPFC 和 TMP 之间有效连接模式的变化可能有助于更好地了解运动对情绪的影响。自我报告的心情。至关重要的是,这种改进伴随着 dlPFC 对 TMP 的更强影响。观察到的 dlPFC 和 TMP 之间有效连接模式的变化可能有助于更好地了解运动对情绪的影响。
