| In 2003,China took women's tennis as a breakthrough to carry out professional reform.Since then,China's women's tennis network has ushered in a golden age.The "Golden Flower of China" represented by Li Na has blossomed in the international arena and won the title of Grand Slam for many times.However,with the retirement of Li Na in 14 years,the competitive status of Peng Shuai and other veterans began to decline,and the record of Chinese women's tennis was gradually criticized by fans.Under the background of the overall decline of China's women's tennis net,Wang Qiang,a Chinese women tennis player,has sprung up in recent years.First,in 2018,she scored in the TOP20 for the first time in the world rankings.In 19,the US Open successfully reached the Grand Slam quarter-finals,and in 2020,the Australian Open defeated Serena Williams for the first time.Behind a series of brilliant achievements made by Wang Qiang,its advanced techniques and tactics played an important role.In this paper,the technical and tactical characteristics of the 19-year-old U.S.Open Wang Qiang in five rounds of competitions are studied by using the methods of literature review,mathematical statistics,comparative analysis,case study and expert interview.The paper analyzes various technical and tactical indicators between Wang Qiang and his opponents from the stage of serving,receiving and sending,and stalemate,and explores their differences.Through systematic research,the paper draws the following conclusions:1.Compared with European and American players,Wang Qiang's service speed is not superior,but her high stability,many rotational changes,reasonable distribution of landing points and high second serve score rate are the key to her victory in the first four rounds.2.In the receiving stage,Wang Qiang has a high success rate of receiving and receiving service,and the depth of returning service is well controlled.Wang Qiang received the opponent's first shot,nearly half of the balls returned to the middle,and there were more slashes.Facing the opponent's second shot,Wang Qiang returned to the middle less and attacked the opponent's two sideline more.3.In the stalemate stage,Wang Qiang and his opponent scored the highest in the stalemate ball with more than 9 beats,followed by 5-9 beats,and Wang Qiang scored the lowest in the short stalemate with less than 5 beats.In the five rounds of competition,Wang Qiang played the most forward and backhand slashes,but the most efficient offensive line in Wang Qiang was the forehand straight line,followed by the backhand straight line and forehand sideways.4.Facing Serena in the fifth round,the success rate of the first round and the low score rate of receiving and sending are the most important factors for Wang Qiang's defeat.In addition,in the stalemate stage,it is difficult for Wang Qiang to keep up with Serena's high-quality and fast-paced return,thus being passive on the court,making it difficult to take the initiative to change the linear growth and stalemate,resulting in a large number of simple points loss. |
