Statistical Analysis on Technical Index of 17th Women's World Championship Based on RSR

利用RSR(秩和比)法等研究方法对第17届女排世锦赛各支球队的整体实力进行综合的量化评价及等级评定,并将中国队与4强对手的技术统计进行对比。结果表明:进攻方面,巴西队的进攻指标RSR值最高(0.81),处于A级水平,中国等9支队伍处于B级水平;防守方面,巴西队RSR值为0.81,仍处于A级水平,中国队的防守RSR为0.65,处于B级水平;攻防转换方面,日本队攻防转换RSR值最高(0.90),处于A级,美国和巴西的攻防转换RSR处于B级,中国队的攻防转换RSR处于C级(0.58);整体实力方面,美国队、巴西队和德国队综合实力处于A级水平,中国(0.65)、意大利等6支队伍处于B级水平。本届世锦赛整体实力RSR排名与最终排名具有高度的相关性R=0.829(P<0.01)。对比四强对手,进攻端,中国队扣球指标表现突出,发球指标除局均发球失误外,局均发球得分、发球得分率均不如对手;防守端,中国队局均拦网得分仅次于巴西队,在局均防守起球上低于美国及巴西;攻防转换端,中国队二传发挥较好,但接发球不稳定。建议中国队加强发球攻击性,提高队伍的整体防守及一传能力。

By using the method of RSR comprehensive e-valuation and other research method, this paper makes a＆amp;nbsp;comprehensive quantitative evaluation and grading of all teams in the 17 th women’s volleyball world champion-ships, and make comparison of the Chinese team with three strong opponents stats. The result shows that in of-fensive,The RSR of Brazil（0. 81）ranks the highest,which belongs to level A,China and other seven teams belong to level B. In defensive, The RSR of Brazil is also 0. 81, which belongs to level A,the RSR of China is 0. 65,which belongs to level B. In offense and defense conversion,the RSR of Japan（0. 90） ranks the highest,which belongs to level A,the RSR of America and Brazil belong to level B, while the RSR of China （ 0. 58 ） belongs to level C. In o-verall strength aspect, the RSR of America, Brazil and Germany belong to level A. The RSR of China,Italy and other 6 teams belong to level B. The RSR of all the teams in overall strength and rank correlation coefficient R =0. 829 （ P〈0. 01 ） , which has significantly related each other. Compared with three strong opponents,In offensive, Chinese team spike indicators outstanding,serving indica-tors, except serving errors, aces per set, ace rates were lower than the three opponents. In defense,China blocking score is only lower than Brazil, and in digging, China is lower than America and Brazil.
