纳达尔红土场比赛技战术特征分析.docx

摘要
本研究通过对纳达尔在 2005-2008 年的 173 场红土场单打比赛进行统计, 利用文献资料法、专家访谈法、数理统计法、录像观察法等科研方法对纳达尔在红土场的单打比赛进行研究,了解纳达尔在红土场地比赛的状况,发现纳达尔在红土场地单打比赛的特征,对影响纳达尔得分能力的相关因素做回归分析, 确定影响纳达尔红土场地比赛得分能力的主要因素并进行解析,最终建立纳达尔红土场地比赛得分能力的数学模型。
研究发现:在红土场比赛中,发球成功率方面,纳达尔与其对手的一发成功率存在非常显著性差异,纳达尔明显优于对手;发球得分率方面,纳达尔的一发得分率和二发得分率均明显优于对手,并且存在非常显著性差异;第一发球落点选择方面,纳达尔一发选择中路落点的次数明显高于对手,具有非常显著性差异,纳达尔与对手在外角和内角的落点选择上相差并不是很大;二发落点选择方面,纳达尔二发偏重于内角和中路,对手二发偏重于外角和内角,相对于对手来说,纳达尔二发突出的特征就是二发更加注重中路落点;ACE 球方面,纳达尔与其对手的 ACE 球数量存在非常显著性差异,对手多于纳达尔;双误方面,独立样本 T 检验的结果显示出二者具有非常显著性差异,纳达尔的双误比对手要少;接发球方面,纳达尔接一发时主要选择打中路战术。接二发时, 纳达尔采用打对方反手的战术,不管是接一发还是接二发,纳达尔的接发球得分率都高于对手;破发方面,纳达尔在比赛中有更多的破发机会,并且比对手更善于把握这些机会;非受迫性失误方面,纳达尔比对手平均每场少 次, 两者之间的非受迫性失误存在非常显著性差异(P<),纳达尔的主动失误较少。影响纳达尔在红土场地得分的主要因素为非受迫性失误、制胜分、发球直接得分和一发得分率 4 个因素,每个因素均具有非常显著性意义。

ABSTRACT
By using the methods of literature, expert interviews, mathematical statistics and video observation, etc, prehend Nadal’s match on clay court, and find the feature of single match on clay court, this paper studies Nadal’s single match which is played on clay court from 2005 to 2008, including 173 matches. Make a regression analyses to the relevant factors of influencing Nadal’s ability to win point, find out the main factors that influence the Nadal’s ability to win point on clay court, and then establish a mathematical model on Nadal’s ability to win point.
The study shows that on the serve points played aspect, the difference is significant on the proportion of first serve points played between Nadal and his opponents on the clay court, and Nadal’s first serve is much better than his opponents; on the serve points won, there are significant difference between Nadal’s first serve points won and second serve points won and his opponent’s, and Nadal’s are much better than his opponent’s; on the first service placement aspect, Nadal choose midtank a lots which is significant difference, the difference is not significant on inside pitch and out part between Nadal and his opponents; on the
