A Comparative Study On Technical And Tactical Characteristics Of Chinese Female Table Tennis Players Ding Ning And Liu Shiwen

Based on the literature of table tennis technique and tactics,this paper makes statistics on the technique and Tactics Application of world excellent female table tennis players Ding Ning and Liu Shiwen in the 22 game videos in 2018 and 2019,analyzes the technique and tactics performance in three stages,and compares and tests the difference between them.The purpose of this paper is to analyze the advantages and disadvantages of the two athletes,to provide some theoretical support for the technical and tactical development of Ding Ning and Liu Shiwen,and to provide some technical and tactical theoretical analysis for them to better participate in the Tokyo Olympic Games.The results show that: the total score rate and total utilization rate of hair snatch section and Ding Ning are higher than Liu Shiwen,but both of them show a downward trend;the total score rate and the total utilization rate of the two parts are equal;the total score rate and the total utilization rate of Liu Shiwen in the stalemate section are higher than Ding Ning.Among them,in 2018 and 2019,the scoring rate and utilization rate of Ding Ning in the hair snatching section were better than Liu Shiwen,but they all showed a downward trend.The scoring rate of Ding Ning decreased from 69.1% to 55.7%,the utilization rate decreased from21.7% to 18.5%,and the scoring rate of Liu Shiwen decreased from 57.1% to 52.8%,with significant difference(P = 0.046),and the utilization rate decreased from 17.6% to 17.5%.Both scoring rate and utilization rate are in the excellent standard.In 2018,the score rate of Ding Ning's receiving and robbing section is higher than Liu Shiwen's,and the utilization rate is lower than Liu Shiwen's;in 2019,the score rate of Ding Ning's receiving and robbing section is lower than Liu Shiwen's,and the utilization rate is higher than Liu Shiwen's.Ding Ning scored 54.0% and 51.6% respectively,and the utilization rate was 23.9% and 30.4%respectively.Liu Shiwen's score rate increased from 50.7% to 55.4%,and the utilization rate was 27.8% and 29.9% respectively.In 2018 and 2019,the scoring rate and utilization rate of Ding Ning's stalemate segment were far lower than Liu Shiwen's.The scoring rate of Ding Ning's stalemate segment decreased from 45.4% to 43.1%,and the utilization rate decreased from 54.4% to 51.1%.The score rate of Liu Shiwen's stalemate decreased from 53.8% to51.5%,and the utilization rate decreased from 54.6% to 52.6%.According to the specific analysis of the three indexes,it is concluded that:(1)when Ding Ning and Liu Shiwen are against different types of players,the overall scoring rate of the three segments is more than 50%;(2)ding Ning is better than Liu Shiwen in the performance of the hair snatching segment;(3)there is little difference between Ding Ning and Liu Shiwen in the scoring rate and utilization rate of the receiving snatching segment;(4)the scoring rate difference between them is obvious in the stalemate segment.Corresponding suggestions are put forward:(1)both Ding Ning and Liu Shiwen should improve the overall scoring rate of the three stages of technology and tactics in the process of innovation;(2)Liu Shiwen should improve the scoring rate and utilization rate of the sending and grabbing stages;(3)ding Ning should improve the scoring rate of the receiving and grabbing stages;(4)ding Ning should improve the overall competitiveness by improving the scoring rate of the holding stages.
