【摘要】 为评价世界精英男子网球运动员比赛表现特征,选取德约科维奇职业生涯2004至2016年间908场、穆雷职业生涯2005至2016年间804场单打比赛为研究对象。运用多元线性回归法对两位优秀网球选手竞技能力技战术指标特征进行分析,运用综合指数法对两人36场比赛对决进行综合评定。结果显示:(1)决定德约科维奇的比赛胜负指标由强到弱依次为二发得分率(0.915)、一发得分率(0.882)、挽救破发点成功率(0.749)、一发成功率(0.700),决定穆雷的比赛胜负指标由强到弱依次为一发成功率(0.803)、二发得分率(0.675)、破发成功率(0.645);(2)德约科维奇与穆雷10场大满贯比赛对决的综合指数平均值分别为3.997和3.862。研究表明:从整体上看,虽然两人职业对决在竞技状态上都有起伏,但并不存在显著性差异,且两人在比赛中均展现出一流的技战术水平。更多还原
