国际优秀女子佩剑运动员进攻决定性动作速度构成和同步性特征的研究

Research on Velocity Component and Synchronization of Offensive Decisive Action for Elite International Female Saber Fencers

运用理论和统计方法,对世界锦标赛和世界杯女子佩剑冠、亚、季军录像解析数据进行了动作速度构成和同步性的分析,结果显示,优秀的技术有助于佩剑速度的发挥,反之亦然,若要保证比赛的胜利就必须保证速度的占优,特别是水平纵深的速度;随着佩剑速度的提高,重心速度对佩剑速度贡献率提高;手相对重心的最大速度和重心最大速度时间相位差可以客观有效地反映决定性进攻动作同步特性;国际优秀女子佩剑运动员的速度同步方式表现为手超前重心所获佩剑护盘速度小于手滞后方式。

The aim of this paper was to analyze velocity component and synchronization of offen- sive decisive action by the method of theory and statistics, basing on resolved video data of elite international saber female fencers who gained respectively first, second and third place on world cup and world championship. The result shows that the greater velocity than rival＇s in particu- lar horizontal velocity ensures victory, though good skill help to increase of saber velocity. Rati- o of ve[ocity of center of gravity （cg） to hand ＇s velocity increases with velocity of saber. It is effectively parameter to reflect synchronized character that difference of time phase of maximal velocity of hand with respect to cg and maximal velocity of cg. Saber velocity is smaller with synchronized way of hand leads cg than lags behind cg.
