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。
Through the analysis and research on the analytical data of the decisive offensive process, the results of the analysis are as follows: The increase rate of the horizontal speed of the speed-type player’s center of gravity is small, The contribution rate of center of gravity in multi-step attack is about 50%, while the speed of synchronized acceleration is too large. The increase of horizontal speed of acceleration player is bigger, and the contribution rate of center of gravity is more than 50% when multi-step attack. The maximum speed of the sword; the premise of safeguarding the victory is higher than the average number of opponents in the attack speed is greater than the number of opponents, but not undoubtedly the pursuit of speed; offensive players to use more advanced synchronization method, High efficiency; synchronous and unsynchronized with the contradictory technical characteristics: unsynchronized Saber 5% ~ 12% of the horizontal speed loss, while reducing the center of gravity and hand the maximum horizontal speed, the establishment of the appropriate time difference will be out of balance two Who, the perfect individual synchronization technology the best choice.
