【摘要】 文章以24名在役射击射箭运动员为测试对象,引入头低位倾斜状态中人体机能反应及变化的研究理论与方法,解决射击射箭运动训练过程中运动员中枢机能恢复问题。结果显示:倒立训练中脑电指标变化幅度十分显著,P3、P4、O1、O2部位α频段功率值下降十分显著,左右额区、左右颞区的β频段功率值出现明显升高现象。同时所观察的7种脑电参数指标也都显著下降。在倒立训练结束后,被试射击射箭运动员各脑电指标则明显高于训练前,尤其是高清醒度、颞同步化、额优势化以及脑电相干函数P3-P4四个指标的提高显著。通过8周倒立训练后,发现运动员所测试的各心理学指标得分均减低,上述现象表明倒立训练改变了运动员大脑血流状态,从而部分影响了其中枢神经功能,在一定程度上改善了运动员的睡眠质量、减轻焦虑、缓解了其在训练后的焦虑情绪及不适症状,随着倒立训练介入时间的增加,其对运动员中枢机能改善的效果愈加明显。更多还原

【Abstract】 In this study, 24 shooting and archery athletes as the test objects, the paper introduces the theory and method of the head down tilt function of human body reaction and state of change, to solve the shooting and archery athletes central function in the process of sports training recovery. The results show: the inverted index variation amplitude of training of EEG is very significant, P3, P4, O1, O2 parts of alpha power decreased very significantly, the beta band power left and right frontal, left and right temporal areavalues increase phenomenon. At the same time of 7 EEG parameters are also significantly decreased. In the inverted state after the end of the training, the subjects of shooters all EEG index was significantly higher than that before the training, especially the HD awake, temporal synchronization, the amount of dominance and EEG coherence function P3-P4 four indicators improved significantly. Through 8 weeks of inverted training, the athletes psychology index score of the test were all reduced, the phenomenon that the inverted training changed the athletes blood flow to the brain, which impact the central nervous function, to a certain extent, improve sleep quality, anxiety, relieve the athletes in the anxiety after training and the ill symptom, along with the increase of the inverted training time, the more effect on athletes can improve obviously the central.更多还原
