| In this paper the use of literature, video observation statistical method and mathematical statistics, comparative analysis and other methods, the2011Australian Open, French Open and Wimbledon3Tennis Open women’s singles, strong athletes to participate in the46×3=138gamestechnical, tactical indicators for the main object of study, the site characterization of three major tennis tournament, the game time, the use of the technical and tactical characteristics of a comprehensive analysis reveals the nature of the different types of sites in three major tennis tournament, the athleteson the technical, tactical play is different. The results show that:1、Analysis of the characteristics of a three venuesTennis Grand Slam venues are different types, in accordance with the materials of the site constitutes divided into four kinds:the concrete field of plastic field such as the Australian Open, U.S. Open, Wimbledon pastures, and the French Open on clay.However, due to the different materials, site surface elasticity coefficient k and the friction coefficient μ, the effect of the site of the surface of the ball there is a bigdifference, such as the ball landed after the rebound height, rebound speed and direction. According to the research needs, in accordance with the site of the ball rebound of the four Grand Slam arena is divided into:fast site (Wimbledon), medium-speed site (Australian Open, U.S. Open) and slow site (French) types. Through the analysis of the principles of mechanics, three major stadium on the ball rebound characteristics expressed as follows:Australian Open venue is a medium speed for faster ball rebound characteristics of the performance of a high degree of relatively fast pitch higher and bounce than the rule, hit the ball the way effectiveness of performance is moderate, the effectiveness of the relatively slow knuckleball pitch decreased; French Open venue is a slow field, the slow rebound of the ball, rebound high and irregular, greatly improve the effectiveness of the spinning ball, especially obvious advantage of topspin; Wimbledon venue is a fast field, the ball rebound speed, the running route of the ball after the rebound is very low, and sliding, bouncing the performance of irregular low performance of the validity of the rotating ball (especially rotation), but strong backspin effect mainly caused by the multiple roles in the fast field of the Earth’s rebound height of very low trajectory and backspin bounce lower. Therefore, three tennis venue on the role of the ball, there are some differences, are bound to athletes in training and competition to master its regularity in order to deal with it smoothly.22011Australian Open, French Open, Wimbledon3Open Tennis women’s singles quarterfinals Players Bureau number, number, number, comparative analysis withAustralian Open hard tennis courts, averaging93minutes with the game on the clay courts at Roland Garros, the average per game with94.4minutes in the clay courts of Roland Garros match the averagefor100.2minutes. French each more than the Australian Open in7.2minutes,5.8minutes more than the Wimbledon; the Australian average use of each plate is39.7minutes, the French Open was43.5minutes, Wimbledon was40.2minutes, the French game of each plate with than when the Australian Open more than3.8minutes,3.3minutes more than Wimbledon, time-consuming from the three major tennis tournament per game average point of view, the French Open Australian Open more than0.3minutes,0.2minutes more than Wimbledon. Consolidated Table12, Table13, Table14, multiple comparison analysis available:Tennis Open at least two games between athletes per game average difference (P<0.05) but not significantly; Tennis Open at least two two athletes per plate between the average difference (P<0.05), but not significantly. Through the above analysis to this conclusion:2011Australian Open, French Open, Wimbledon Women’s Singles8athletes in the race, the existence of such a law:French Open (clay), Wimbledon (grass)> Australian Open (hard).3The technical features of different venues in the world’s outstanding women’s singles,8athletesACES ball out of scoring rate, average fastest serve speed, an average of two rounds of the fastest ball speed, average out of the fastest serve speed is the key factor to win three major tennis tournament, the top8athletes, and compared with ACES ball of the Wimbledon stadium, out of the scoring rate more prominent; the fastest ball speed, the average first serve speed of the fastest serve, an average of two rounds of three indicators of the fastest serve speed, the French Open> Australian Open and Wimbledon.The French Open, Australian Open and Wimbledon significant difference (P <0.05), French Open and Australian Open different, but not significant (P<0.05). It can be seen in tennis training, similar to the Wimbledon grass types of sites, according to the characteristics of the grassland sites, to improve the situation on the offensive, you should do some appropriate adjustments to improve the situation offensive performance to suppress the direct opponents score tactical arrangements. Furthermore, according to the characteristics of pasture:the ball landed small friction with the ground, the ball’s rebound speed fast, can do the combination of four athletes in four aspects of strength, speed, rotation, placement, and in the race for more victory.4Different venues in the world’s outstanding women’s singles,8athletes serve receive technical featuresReturn of serve different venues nature, its technical, tactical play is not the same, get on the fast site performance and the most prominent, low scoring rate, but it is one of the key reasons for victory.and the scoring rate of return of serve is one of the key factors of the three major tennis tournaments Women’s Singles Top8athletes win Wimbledon Top8athletes Receiving scores were lower than the Australian Open and French Open, Australian Open> French> Wimbledon; Wimbledon break were higher than the French Open and Australian Open and a significant difference (P<0.05), Wimbledon> French> Australian Open, which fully demonstrates the characteristics of the site is very associated, indicating that the break in the Wimbledon stadiumthe validity of the rate is the highest, and it is decided a very important factor towards the tennis tournament. It can be learned tennis training and competition should be based on site characteristics unique to a special reception training, special individual training to the opportunity to grasp the ball to break their competitive abilities in the game, especially targeted reception training should be strengthened in the type of grass such as Wimbledon venue game.5Different venues in the world’s outstanding women’s singles,8athletes skills, the use of tactical analysisTechnical, tactical use of indicators in2011, proactive awareness of the three major tennis tournament athletes stronger and compared to the analysis under Wimbledon8athletes take the initiative to the highest scoring efficiency, from the winning goal/unforced errors ratio of1.49(Figure4) can be seen, Wimbledon eight athletes to the smallest mistakes and get more victory points; lower the stability of the Australian Open and French Open8athletes at the Australian Open and French Openunder the technical and tactical play of stability compared to Wimbledon is relatively critical. Our findings suggest a training and competition can start from the analysis of track characteristics, looking for opportunities in the race and take the initiative to launch oppressive offensive, like the Wimbledon stadium strong athletes with minimal mistakes and get more winning points. |
