为评价运动干预对抑郁症大学生的改善效果，探讨其静息态脑电（EEG）的微观状态和功率谱的变化特征。采用Beck抑郁量表-II（BDI-II）和抑郁自评量表（SDS）对40名中度抑郁女大学生进行筛选，其中一半进行为期18周的运动干预。该研究利用EEG来定义静息状态网络，并在干预期间跟踪所有参与者的分数。与抑郁组相比，运动干预组θ、α频段功率谱值显著降低（p < 0.05），微状态C持续时间显著增加（p < 0.05），微状态B频率显著降低（p < 0.05）。运动干预组从B到D的转移概率高于抑郁组（p < 0.01）。此外，运动干预后δ和α波功率与微状态C的发生呈负相关（分别为r =-0.842，p < 0.05和r =-0.885，p < 0.01），β波功率与微状态C持续时间呈正相关（r = 0.900，p < 0.01）。我们的研究结果表明，减少持续时间的微状态C和增加阿尔法功率在抑郁症的学生与认知能力，情绪稳定性和大脑活动降低。运动干预后抑郁症状明显改善，为抑郁症的研究、康复机制和治疗提供了更科学的指标。
This paper aims to assess the effect of exercise intervention on the improvement of college students with depression and to explore the change characteristics of microstates and the power spectrum in their resting-state electroencephalogram (EEG). Forty female college students with moderate depression were screened according to the Beck Depression Inventory-II (BDI-II) and Depression Self-Rating Scale (SDS) scores, and half of them received an exercise intervention for 18 weeks. The study utilized an EEG to define the resting-state networks, and the scores of all the participants were tracked during the intervention. Compared with those in the depression group, the power spectrum values in the theta and alpha bands were significantly decreased (p < 0.05), and the duration of microstate C increased significantly (p < 0.05), while the frequency of microstate B decreased significantly (p < 0.05) in the exercise intervention group. The transition probabilities showed that the exercise intervention group had a higher probability from B to D than those in the depression group (p < 0.01). In addition, the power of the delta and alpha bands were negatively correlated with the occurrence of microstate C (r = -0.842, p < 0.05 and r = -0.885, p < 0.01, respectively), and the power of the beta band was positively correlated with the duration of microstate C (r = 0.900, p < 0.01) after exercise intervention. Our results suggest that the decreased duration of microstate C and the increased alpha power in depressed students are associated with reduced cognitive ability, emotional stability, and brain activity. Depression symptoms were notably improved after exercise intervention, thus providing a more scientific index for the research, rehabilitation mechanisms, and treatment of depression.
