2014-2015赛季CBA季后赛与非季后赛球队攻防竞技能力比较研究

Comparison of offensive and defensive competitive ability between the teams in the 2014-2015 playoffs and regular seasons

运用文献资料法、秩和比法、独立样本T、率的X2检验与录像观察法,对2014-2015赛季CBA季后赛与非季后赛球队的攻防竞技能力给予综合等级评价分析,探求季后赛与非季后赛球队在比赛攻防竞技能力方面的差距。研究结果表明:季后赛球队的攻防能力RSR值为0.7596,隶属于B级水平,非季后赛球队的攻防能力RSR值为0.3688,隶属于D级水平,季后赛球队的攻防能力对比非季后赛球球队,攻防能力具有显著性差异,表现在进攻能力上,季后赛球队二分球、三分球、罚球、命中率,助攻、控制失误次数等相关指标上,明显要高于非季后赛球队;在防守方面,季后赛球队的防守篮板球统计指标也同样高于非季后赛球队。

With the methods of literature review,rank sum ration,the rate of independent sample T,X2 test and video observation research,we made a comparative analysis of the attack and defense ability of the teams in 2014- 2015 CBA playoffs and regular seasons and gave a comprehensive grade evaluation,in a view to find out the disparity between them. The results show that the offensive and defensive ability RSR value of playoff teams is 0. 7596,belonging to the class B level,while the RSR value of teams in regular seasons is 0. 3688,belonging to D level,the difference being obvious. Moreover,in respect of the offensive abilities such as two- point shot,3- point shot,free throw,field goal percentage,assist and control error,the regular season teams fall obviously behind the playoffs; for the defensive ability,the defensive rebound of playoff teams are much better than the regular season teams. Finally,suggestions are given based on the comparative analysis.
