| Research purpose: According to the theory of event group in sports training,tennis belongs to the antagonistic event of net separation dominated by technical and tactical ability,and the technical and tactical level is the decisive factor of athletes’ competitive ability.The purpose of this paper is to study the technical and tactical characteristics of Zhang Shuai and Stosur in the 2021 US Open women’s doubles competition,analyze their winning factors,and provide theoretical reference for China’s women’s doubles events.Research methods: Using the methods of literature,video analysis,mathematical statistics and comparative analysis,this paper makes data statistics and analysis on the technical and tactical application of the 2021 US Open women’s doubles match between Zhang Shuai and Stother.Research results:1.Serving stage: the scoring rate of the first serve and the second serve are higher than those of the opponent;The landing points of the first and second engines are mainly external angles;The stations are mainly based on one bottom and one website,supplemented by Australian stations;In order to ensure the aggressiveness,the third racket mainly uses diagonal forward and backhand strokes and volleys.2.Receiving and serving stage: most of the stations at the time of receiving the first serve are double bottom line stations,and the second serve station is the first bottom line station and the second serve station.The receiving and serving line is basically diagonal line,and the probability of diagonal line is higher at the time of receiving the second serve;The technique of receiving and serving is mainly backhand stroke;The fourth racket is mainly a forehand draw with a diagonal line.3.Stalemate stage: the hitting technique is mainly the volleying and volleying,and the utilization rate of volleying technique increases with the increase of the number of shots.The position is mainly based on one bottom and one net,but the players will actively seize the double net position in the stalemate stage.At the same time,volleying is also the hitting technique with the highest scoring rate.Research conclusion:1.Serving stage: the scoring rate of the first serve is high,but the change is insufficient.We should strengthen the targeted training on the placement and rotation of the serve,not blindly pursue the Ace ball,and more think about how to mobilize the opponent to pave the way for attack;The service technique and tactics should be combined with the third racket technique and tactics,and the third racket should try to use offensive hitting methods such as volleying.2.Receiving and serving stage: receiving the first serve and receiving the second serve are totally different tactical strategies.The receiving and serving tactical strategy is to defend the counterattack stably and try not to make mistakes;The tactical strategy of the second round is to take the initiative to attack and strive for the first advantage;Strengthen the connection between receiving service and the fourth racket,and look for opportunities to actively surf the net.3.The stalemate stage: both sides have a strong sense of attack since the goal of reaching the net,so the choice of hitting techniques cannot be conservative.Intercept and forehand draw should be the first choice of hitting techniques;The fast pace of attack and defense conversion in the stalemate stage has higher requirements not only in terms of technology,but also in terms of physical ability,psychology and the tacit understanding between teammates. |
