摘要
运用灰色关联理论,通过文献资料、录像观察和数理统计等多种方法,对第30届奥运会男子篮球比赛各球队的技战术指标进行统计与分析,研究影响本届奥运会比赛成绩的主要因素及发展趋势。研究结果表明:第30届奥运会男子篮球比赛15项技术指标中有7项指标与得失分率、比赛名次关系最密切,这7项指标与比赛成绩有非常显著性差异,存在线性关系;本届奥运会男子篮球比赛的攻防转换速度进一步加快,进攻次数明显增加,进攻效率越来越高,稳定的投篮命中率成为影响本届奥运会篮球比赛成绩的最重要因素;探讨了美国队和中国队成败的关键因素;运用灰色关联分析和秩相关分析研究第30届奥运会男子篮球比赛各球队技战术水平具有实际意义,是一种研究篮球运动技战术水平的有效方法。
