| 摘 要： | 运用高速摄像机现场获取了世界杯和世锦赛女子佩剑冠亚季军决赛和半决赛的影像资料,通过对决定性进攻过程解析数据的分析和研究,结论如下:速度型选手重心水平速度增加量较小,多步进攻时重心速度贡献率约为50%,同步提速期屈臂过大,加速型选手重心水平速度增加量较大,多步进攻时重心速度贡献率大于50%;选手的爆发力决定着佩剑最大速度;保障胜利的前提是进攻中高于对手的平均水平速度的数量要大于对手,但不片面追求速度;进攻中选手多采用手超前的同步方式,相比手滞后同步方式其速度小防守有效性高;同步与不同步具有矛盾的技术特征:不同步造成佩剑水平速度5%~12%的损失,同步则降低重心和手的水平最大速度,确立适宜的不同步时间差将是均衡两者、完善个体同步技术的最佳选择。

| Abstract: | By high-speed camera on the spot,video data was obtained of which the first,the second and the third of elite female saber fencer who were playing in the final and the half final on the World Cup and World Championship.This paper was designed to study on technical character of the process of decisively offense basing on the resolved video data.It showed that the ratio of horizontal velocity of center of gravity(cg.) to the velocity saber is about 50% for the fencers of speed style while it is more than 50% for the fencers of accelerative style in many feet attack.Horizontal acceleration of cg is smaller and bending extent of upper arm is larger for the fencers of speed style than accelerative style.Maximal horizontal velocity of hand holding saber depends on the power.It ensured win that the number of greater mean horizontal velocity is more than the rival’s,but not only the velocity.Horizontal saber velocity is smaller and the security is higher with synchronized way of hand leads cg than lags behind cg in decisively offense,although the majority uses frequently the way of hand leads cg.It is contradictious in the technique that not synchronizing decreases 5%~12% of the saber horizontal velocity,while synchronizing reduces maximal horizontal velocity of hand and cg.To search optimum nonsynchronous time is very likely to balance the both and to perfect individual synchronous technique. |
