世界杯女子佩剑决定性动作起动和时机距离值的准定量研究

Semi-Quantitative Research on Start and Opportune Distance of Decisive Action for World Cup's Female Sabre Fencers

为使佩剑研究可定量化,将技术类别划分为一单步和多单步对攻以及单纯进攻和单纯防守,通过录像解析数据对世界杯女子佩剑冠、亚、季军技术进行了定量和统计分析。结果显示,以身体重心水平速度为基准,参考录像表象分析,所确定决定性动作的起动时刻更客观有效可信,由此确定的时机距离较好地反映了运动员对进攻时机和进攻有机组合距离值的把握能力;双方的前脚间距是培养适宜时机距离感的重要指标,双方后脚间距离是诊断时机距离准确可靠的单选指标;对攻时,相对对手略微晚起动和缩小时机距离是女子佩剑优秀运动员的原则性特征技术。

This paper made dividing saber technique into one foot both attack, many feet both attack, single offense and single defense for analyzing quantificational and statistically it of 3 world cup＇s female saber fencers by its video date. It concluded that in the light of body weight minimum horizontal velocity the start time of decisive action is differentiated, and then defining the opportune distance which reflects effectively and objectively controlling opportunity and well-timed synthetic distances ability. The distant between both front foots is important parameter to train distant sense. The distant between both behind foots is select accuracy parameter to diagnose opportune distance. The elite female saber fencers possess the characteristic technique in principle with actively decreasing opportune distance and delaying start a little in both attacks.
