为了解不同水平竞走运动员的脑电α波特点,探讨其项目内稳态的EEG信号特征,利用高级运动训练监控仪采集5名健将级竞走运动员不同训练阶段56个样本的EEGα波数据,采用主成分分析和序参量理论提取竞走运动员SpSH所隐含的竞技水平信息进行统计分析。结果发现：状态优秀运动员SpSH品质明显高于状态一般运动员。说明竞走运动员EEGα波的序参量（优势频率10 Hz）可以表征其SpSH品质。
為瞭解不同水平競走運動員的腦電α波特點,探討其項目內穩態的EEG信號特徵,利用高級運動訓練鑑控儀採集5名健將級競走運動員不同訓練階段56箇樣本的EEGα波數據,採用主成分分析和序參量理論提取競走運動員SpSH所隱含的競技水平信息進行統計分析。結果髮現：狀態優秀運動員SpSH品質明顯高于狀態一般運動員。說明競走運動員EEGα波的序參量（優勢頻率10 Hz）可以錶徵其SpSH品質。

In order to understand the EEG α wave characteristics of race walkers at different levels,and to probe into the EEG signal characteristics of their sport-specific homeostasis,the authors collected the EEG α wave data of 56 specimens of 5 master race walkers at different stages of training by using an advanced sports training monitor,extracted competitive performance information implied in the SpSH of the race walkers,did a statistical analysis by means of principal component analysis and order parameter theory,and revealed the following finding： the SpSH quality of a race walker in excellent condition is significantly higher than that of a race walker in ordinary condition,which means that the order parameter（dominant frequency at 10 Hz） of the EEG α wave of a race walker may represent his/her SpSH quality.
