Application And Research On The Technical And Tactical Benefit Value Of The First Four Boards Of Xu Xin And Liu Shiwen In The Competition Based On Boston Matrix

In order to further improve the efficiency of the tactical assessment of mixed doubles athletes,improve the accuracy of my country’s table tennis in the mixed doubles competition,in order to prepare for the Paris Olympic Games.Based on the method of literature and data method,expert consultation method and video statistics,this study applies the Boston matrix analysis model to the analysis of table tennis skills and tactical benefits,and uses three segment indicators to evaluate the "Boston Matrix Tactical Analysis Model".Feasibility.This article accurately obtained the tactical combination of Xu Xin/Liu Shiwen’s mixed combination in major competitions through the Boston matrix tactical model.Xin/Liu Shiwen combined against the left and right hands pairing and the problems existing on the right-handed skills and the advantages of the tactics,so as to conduct targeted scientific training to provide strong theoretical support and scientific science for winning the Paris Olympic Ping Pong Dual Gold Medal Suggestions.The following conclusions are obtained through the analysis of tactical benefits through the Boston matrix tactical model:The highest tactical value in the right-handed combination is(100%,14.29%)in the pairing pairing.;Tactical benefits are the lowest(20%,8.93%),which is the tactical combination B3 of Xu Xin’s sending wheel.After the tactical combination is the opponent’s short-handed ball,Xu Xin uses the twisting technology to return to the opponent’s backhand to the opponent’s backhand.Long ball,the opponent used the backhand attack technology to return the ball to Liu Shiwen’s backhand long ball,Liu Shiwen used the backhand technology.The highest tactical benefits in the combination of the left and right hands are(100%,10.71%),and the tactical combination E1 in the tactical combination of Xu Xin,the tactical combination is directly scored by Xu Xin through a short-handed ball;tactical benefits are tactical benefits;tactical benefits;tactical benefits;The lowest tactical combination is Liu Shiwen’s tactical combination H6(0%,5.08%).After its tactical combination is the opponent’s short-handed ball,Liu Shiwen uses a short technology to return to the opponent’s positive and short ball.Pulling back the ball to the long ball,Xu Xin judged that the mistake was not used in time to use the positive players.And give the corresponding suggestions for its conclusions:When combining the right right hand,Xu Xin’s training should pay attention to increase Xu Xin’s tactical exercise after the screwing.Pulling back the ball to the opponent’s backhand long ball,the opponent used the backhand attack technology to return the ball to Liu Shiwen’s backhand long ball,Liu Shiwen should pay more attention to the training of the tactical combination of backhand technology.When the combination of the left and right hands,Liu Shiwen’s training should increase the opponent’s short-handed ball or side spinning ball in the training of the ball.The backhand attack technology counterattacks back to Xu Xin’s backhand long and positive long balls.Xu Xin used the tactical combination exercise of positive arc ball technology to reduce the scoring rate of such tactics.
