乒乓球技战术能力分析中的代理模型方法研究

Research on Surrogate Model Method of Analysis of Table Tennis Technical and Tactical Ability

研究了用于乒乓球技战术能力分析的代理模型方法,针对高校大学生乒乓球运动员比赛的得失分情况进行了分析整理,在“四段指标评估法”的框架下,计算了发抢得分率、接抢得分率、发球相持得分率、接发球相持得分率四项能力指标.在此基础上,利用基于径向基函数的代理模型方法,构建了四项能力指标与局得分率的函数关系.利用该函数,可以实现局得分率的预测,并且通过求导运算能够分析得到各项能力指标的变化对局得分率的影响程度,找到其中应该重点改进的环节,可为今后实施有针对性的训练提供一定的理论依据和参考.

The surrogate model method for analyzing table tennis technical and tactical ability is studied.Through analyzing the scores of table tennis players in colleges and universities,four ability indexes are calculated under the framework of four-segment index evaluation method.The four ability indexes are the scoring rates of attack after service,receive and attack,stalemate stage Ⅰ and stalemate stage Ⅱ.On this basis,the surrogate model based on radial basis function is used to construct the functional relationship between the four ability indexes and the scoring rate in a game.Using this function,it is possible to realize the prediction of the scoring rate in a game.Through the derivative calculation,the influence degree of the change of various ability indicators on the score rate of the game can be analyzed,and the key improvement links can be found,which can be targeted for future implementation,and provide a certain theoretical basis and reference for targeted training.
