我国优秀击剑运动员神经活动特性的研究

Research on Characteristics of the Chinese Elite Fencers' Nerve Activity

选取国家击剑队,江苏省击剑队和江苏省体校击剑队员为被试,共115名。采用MANOVA分析了不同运动等级、不同剑种运动员的神经活动特性,研究结果发现:击剑运动员神经活动的平衡性、强度、灵活性和稳定性指标随着运动等级的提高表现出了明显的递进式变化,健将级以上运动员较健将级以下运动员的优势显著。在神经活动的稳定性上,佩剑运动员显著低于重剑和花剑运动员。顶尖水平佩剑运动员在"刺激-反应"任务上倾向于适度控制准确性而追求最快反应速度。运动员神经活动平衡性、强度、灵活性和稳定性的4项观测指标具有较高的鉴别力,可以作为高水平击剑运动员选材和训练水平的评价指标。

The study examined the characteristics of fencers＇ nerve activity.Ss were 115 fencers,who were from National fencing team,Jiangsu team and Jiangsu physical education school.Grade and category were tested with MANOVA.The results indicated that there were significant differences in equitability,intensity,flexibility and stability across grades-the higher grade,the better performance.The top two grade fencers show the very significant superiority to the third one.The sabre fencers＇ stability was significantly lower than epee and foil fencers＇.The top level sabre may prefer to react fast in performing a ＂stimulus-response＂task on condition that he could control the accuracy within his limit.The four observed variables of athletes＇ nerve activity were effective and could be used as indexes of talent selection and training assessment.
