摘 要:为了探讨职业网球运动员比赛获胜的制胜因素,采用Logistic回归分析法,以2019年温布尔登网球公开赛男子单打比赛254场比赛的"胜、负"作为因变量,以128名网球运动员的比赛中各技术数据及网球运动员基本情况指标因素作为自变量,构建基于logistic回归的职业网球运动员制胜因素判断模型。结果表明:影响职业网球运动员制胜的关键因素为一发得分率、二发得分率、一发接发球得分率、二发接发球得分率和反手握拍类型。提出职业网球运动员要进一步提高发球得分率和接发球得分率,且使用双手反手握拍获胜的概率较高,这对于我国男子网球运动员的科学化训练具有一定的指导意义。In order to explore the winning factors of professional tennis players'winning,this study uses Logistic regression analysis to take the"wins and losses"of the 254 games of the 2019 Wimbledon men's singles match as the dependent variable,with 128 tennis players The technical data and basic factors of tennis players in the game are used as independent variables to build a winning model for professional tennis players based on logistic regression.The results show that the key factors influencing the success of professional tennis players are the first serve scoring rate,second serve scoring rate,first receive serve scoring rate,second receive serve scoring rate and backhand grip type.It is proposed that professional tennis players should further improve the service scoring rate and service scoring rate,and the probability of winning with two-handed backhand grips is high,which has certain guiding significance for the scientific training of Chinese male tennis players.
