Abstract：
Although exercise training has been shown to enhance neurological function, there is a shortage of research on how exercise training affects the temporal-spatial synchronization properties of functional networks, which are crucial to the neurological system. This study recruited 23 professional and 24 amateur dragon boat racers to perform simulated paddling on ergometers while recording EEG. The spatiotemporal dynamics of the brain were analyzed using microstates and omega complexity. Temporal dynamics results showed that microstate D, which is associated with attentional networks, appeared significantly altered, with significantly higher duration, occurrence, and coverage in the professional group than in the amateur group. The transition probabilities of microstate D exhibited a similar pattern. The spatial dynamics results showed the professional group had lower brain complexity than the amateur group, with a significant decrease in omega complexity in the α (8-12 Hz) and β (13-30 Hz) bands. Dragon boat training may strengthen the attentive network and reduce the complexity of the brain. This study provides evidence that dragon boat exercise improves the efficiency of the cerebral functional networks on a spatiotemporal scale.
摘要：
尽管运动训练已被证明可以增强神经功能，缺乏关于运动训练如何影响功能网络的时空同步特性的研究，对神经系统至关重要。这项研究招募了23名专业和24名业余龙舟赛车手，在测力计上进行模拟划桨，同时记录EEG。使用微状态和omega复杂性分析了大脑的时空动力学。时间动力学结果表明，微态D，它与注意力网络有关，出现显著改变，持续时间明显更长，发生,专业组的覆盖率高于业余组。微状态D的转变概率表现出相似的模式。空间动力学结果显示，专业组的大脑复杂度低于业余组，在α（8-12Hz）和β（13-30Hz）频段中，Ω复杂度显着降低。龙舟训练可以加强专注的网络，降低大脑的复杂性。这项研究提供了证据，证明龙舟运动在时空尺度上提高了大脑功能网络的效率。
