The physiological function of the Mu rhythm (8-13 Hz in the central region) is still unclear, particularly its role in visuomotor performance in sports (shooting vs. golf putting), as both the complexity of the motor skills (i.e., simple vs. complex visuomotor skills) and the skill level (e.g., novices vs. experts or low-skilled vs. highly skilled) may modulate Mu rhythm. To gain a broader understanding of the association between Mu rhythm and visuomotor skill performance, a study design that considers both a control moderator (the difference in skill level) and the ability to manipulate Mu rhythm (i.e., either increase or decrease Mu rhythm) is required. To achieve this, we recruited 30 novice golfers who were randomly assigned to either the increased Mu rhythm group (IMG), decreased Mu rhythm group (DMG), or sham group (SG) and used electroencephalographic-neurofeedback training (EEG-NFT) to manipulate Mu rhythm during a golf putting task (complex visuomotor skill). The aim was to determine whether the complexity of the motor skill was a potential moderator of Mu rhythm. We mainly found that Mu power was significantly decreased in the DMG following EEG-NFT, which lead to increased motor control and improved performance. We suggest that (1) the complexity of the motor skill, rather than the difference in skill level, may be a potential moderator of Mu rhythm and visuomotor performance, as our results were not consistent with a previous study that reported that increased Mu rhythm improved shooting performance (a simple visuomotor task) in novices.
缪波节律（中枢区域8-13赫兹）的生理功能仍不清楚，尤其是其在体育运动中视觉运动表现（投篮与高尔夫球推杆）中的作用，因为运动技能的复杂性（即简单与复杂的视觉运动技能）和技能水平（例如新手与专家或低技能与高技能）都可能调节缪波节律。为了更全面地理解缪波节律与视觉运动技能表现之间的关联，需要一种既考虑控制调节因素（技能水平差异）又具备操纵缪波节律能力（即增加或减少缪波节律）的研究设计。为此，我们招募了30名新手高尔夫球手，他们被随机分配到缪波节律增强组（IMG）、缪波节律减弱组（DMG）或假刺激组（SG），并在高尔夫球推杆任务（复杂视觉运动技能）期间使用脑电图神经反馈训练（EEG-NFT）来操纵缪波节律。目的是确定运动技能的复杂性是否是缪波节律的潜在调节因素。我们主要发现，EEG-NFT后DMG组的缪波功率显著降低，这导致运动控制增强和表现改善。我们认为：（1）运动技能的复杂性而非技能水平差异可能是缪波节律和视觉运动表现的潜在调节因素，因为我们的结果与之前一项研究不一致，该研究报告称缪波节律增强可改善新手的投篮表现（简单视觉运动任务）。
