The brain mechanisms by which music-related interventions ameliorate fatigue-related symptoms during the execution of fatiguing motor tasks are hitherto under-researched. The objective of the present study was to investigate the effects of music on brain electrical activity and psychophysiological measures during the execution of an isometric fatiguing ankle-dorsiflexion task performed until the point of volitional exhaustion. Nineteen healthy participants performed two fatigue tests at 40% of maximal voluntary contraction while listening to music or in silence. Electrical activity in the brain was assessed by use of a 64-channel EEG. The results indicated that music downregulated theta waves in the frontal, central, and parietal regions of the brain during exercise. Music also induced a partial attentional switching from associative thoughts to task-unrelated factors (dissociative thoughts) during exercise, which led to improvements in task performance. Moreover, participants experienced a more positive affective state while performing the isometric task under the influence of music.
迄今为止，关于音乐相关干预在执行疲劳性运动任务期间改善疲劳相关症状的大脑机制的研究还不够充分。本研究的目的是调查在执行等长疲劳性踝关节背屈任务直至自愿疲劳点的过程中，音乐对大脑电活动和心理生理指标的影响。19名健康参与者在最大自主收缩的40%强度下，分别在听音乐和安静状态下进行了两项疲劳测试。使用64通道脑电图评估大脑的电活动。结果表明，运动期间音乐下调了大脑额叶、中央和顶叶区域的θ波。音乐还在运动期间诱导了部分注意力从联想思维转向与任务无关的因素（解离思维），从而导致任务表现的改善。此外，参与者在音乐影响下执行等长任务时体验到了更积极的情感状态。
