Background: The reason why table tennis can be called China’s national ball is because table tennis symbolizes the prosperity of the country,and it is also the perfect embodiment of the rapid rise of China’s comprehensive national strength,national honor and patriotic spirit.In recent years,table tennis in various countries in the world has flourished,and the level of table tennis players in various countries has gradually approached China,especially in the mixed doubles final of the 2020 Tokyo Olympic Games,the combination of Ito Mishimasa and Mizutani Hayabusa defeated China and won the championship.Objective: The purpose of this study is to study the use of Wang Chuqin’s techniques and tactics in important competitions,to find out the advantages and disadvantages of Wang Chuqin’s use of techniques and tactics in important competitions,and to provide some feasible reference for Wang Chuqin’s future technical and tactical training to focus on improving,so as to continuously maintain and improve the world-leading level of Chinese national football.Methods:Using the currently recognized four-stage index evaluation method,taking the famous young national player Wang Chuqin as an example,the mathematical statistical analysis of the scores gained and lost,the scoring techniques of serving and receiving the ball,the scoring techniques of the serve and the serve technique,and the stale holding scoring techniques were analyzed mathematically.Results: Through the analysis,the technical and tactical indicators are summarized,which have the following characteristics:[1] Wang Chuqin has many fake actions before and after the serve action,which has a very strong confusion,in the choice of serve route,mainly the forehand position or middle road of the opponent,the landing point is mainly distributed in the positive short or short,and the serve is its dominant technology.[2] In the handling of the docking serve,Wang Chuqin dared to get started first,and mostly used the backhand twisting or forehand rubbing techniques to use the most frequently,and the swing arc was low.In the round of receiving the ball,Wang Chuqin’s 4th cricket was mainly offensive,and his scoring rate in defense was low and his performance was poor.In the use of 2 and 4 board tactics,the scoring rate is not high and does not occupy an advantage,in addition,the scoring rate of the serve round is slightly lower than the scoring rate of the serve round,which proves that Wang Chuqin does not have a significant advantage in the receiving link,and the performance of the receiving section is average.[3] Wang Chuqin will choose to use offensive techniques for the handling of the3 rd cricket,supplemented by control technology,and in the use of tactics on the 1st and 3rd boards,the scoring rate is slightly lower and does not dominate,but from the overall performance of the serve round,it is its dominant segment.[4] In the phase Ⅰ stage,Wang Chuqin’s continuous attack is powerful,the front and backhand connections are very smooth,and when standing in the middle and close platforms,the counterattack speed is fast and the rotation is strong,which is the most advantageous section in the four stages,and the performance is the most outstanding.The flexible use of the return line after the 5 boards,always catching the opponent’s gap,and the angle of the counterattack is large,which is its dominant segment.[5] In the second stage of the holding,Wang Chuqin is easy to be passive or moved by the opponent and lead to loss of points,and his ability to smoothly enter the second stage of the holding is relatively small compared to other paragraphs,and the second stage of the holding has the lowest scoring rate and low utilization rate in the four paragraphs,which is its disadvantaged segment.In summary,from the overall point of view,Wang Chuqin’s strength in each section is relatively balanced,the proportion of each section is more reasonable,there is no more obvious defective technology,each section has different playing characteristics,and the strategic and tactical means are diverse. |
