| In recent years, the rapid development of tennis, Li Na won the French Open women’s singles champion, was the first woman to win the grand slam tennis singles champion Asians, Wu Di became the first Grand Slam tournament is in the China men, created the history, China players break set off a wave of irresistible tennis boom.In this paper, using the method of literature, video observation and statistics, mathematical statistics, comparative analysis and other methods, to participate in the2013Australian Open, the French Open and Wimbledon3grand slam tennis men’s singles top8athletes of the46×3=138game technical, tactical index as the main research object, the venue, the characteristics of3grand slam tennis by using characteristic time, technical and tactical analysis, reveals the3Grand Slam Tennis of different types of sites are different in nature, the athletes in the technical, tactical play effect is different. Comparative analysis the following conclusions:1, international standard tennis court is composed of four different materials, the most famous of the four Grand Slam Tennis venue is formed, by these four different materials are:plastic ground Australian Open, Wimbledon Lawn, clay’s French, concrete ground U. s.. However, because the tennis courts of different materials, different site index, coefficient are also different, such as elastic and friction, the two important factor has very big difference in different site, it reflects the bounce rate, bounce height and bounce direction. Because the research needs, according to different site indexes of the ball, the difference of the coefficients, which represent different site of the four Grand Slam site is divided into:Fast Pitch (Wen Wang), medium pitch (Australian Open, US Open), slow pitch (French) three types of site. The three grand slam the ball mechanics analysis, the elastic characteristics of the ball:the Australian Open tennis tournament is medium field, elastic characteristics of ball is faster, the bounce is regular, and bounce to fast pitch high, was relatively modest in the batter’s method, compared with the slow the stadium, the decrease of relative effectiveness of rotating the ball; the French Open tennis tournament to slow the site, elastic characteristics of ball is slower, the bounce of the ball is irregular, and bounce high, effective rotating ball has been greatly improved, in the French site use top spin technology advantage especially; Wimbledon belongs to rapid field, ball elastic character is very fast, the bounce of the ball is very irregular, and route running the ball bounces very low, after the rebound ball and slide forward signs, spin is not dominant in the Wimbledon area (especially with topspin, backspin) but in the Wimbledon area obvious advantages, mainly because the ball on the lawn after jumping line operation is very low, coupled with the use of underspin shot at any site on the ball bounces and the track is Low, however in the Wimbledon Lawn use, trajectory is more lower. So it is, the three Grand Slam venues on ball functions also have some differences, so the athletes in competition and training in daily to different sites, to understand its characteristics, such ability in the game should ease.2, in the hard court tournament games, averaging177minutes when, in the grassland site on the Wimbledon Championships, averaging168minutes when, in the clay of Roland Garros in, the average time is194minutes. The averaged with highest, more than17minutes for the Australian Open, Wimbledon and more than26minutes; the Australian average per disk for51.4minutes to55.5minutes, French Open, Wimbledon for48.8minutes, the game each plate with4.1minutes more than the Australian Open, Wimbledon and the more than6.7minutes from time, an average of three Grand Slam each bureau, the French Open more than0.4minutes,1minutes more than net. Through the above game analysis we can draw such a conclusion:in2013three different sites (Australian Open, French Open, Grand Slam Wimbledon) the existence of such a rule of men’s singles top8athletes in the game with:French (red), Wimbledon (grassland), Australia (hard).3, ACE ball, a round of score rate, average fastest serve speed, average two fastest serve speed, average a fastest serve speed is the key factor of3tennis open top8players to win, and in contrast, Wimbledon stadium ACE ball, a round of score rate is prominent; the fastest serve speed, average a fastest serve speed, average two fastest serve speed on three index, the Australian Open, French Open, wimbledon. Thus it can be seen, in tennis training, for the type of grassland site similar to Wimbledon. according to the characteristics of grassland sites, in improving the offensive a hair, should make some adjustments, so as to improve the performance of an offensive to suppress opponents score directly tactical arrangement, and according to the characteristics of friction:grassland the ball hit the ground and the ground is small, the bounce of the ball speed, jumping height and low sliding phenomenon, athletes can achieve the combination of the four and more victory in the competition in four aspects of power, speed, rotation, placement. Similar to the red clay of the French Open Type site, should be concentrated on the rotation of the control on the serve, ready to back technology.4, in the return of serve, due to the different nature of the site, technical, tactical play effect is different, in the rapid site on the performance of the most prominent, the scoring rate is relatively low, but it is one of the key reasons for success, and the scoring rate is one of the key factors the3grand slam men’s singles top8athletes win, through the table data display, receive serve scoring rate is less than the Australian Open and French Open Wimbledon, the French Open>> Wimbledon; break rate, the Australian law>> Wimbledon, this fully illustrated5, in the use of skills, tactical index,3open8strong players active attack consciousness is stronger, and compared analysis, Wimbledon’s net score was71.5, the average winner for30.8, non damage failure was28.9, while the French network before scoring rate was68, the average the winner was36.9, non damage error is37, the Australian net score was70.8, the average winner for30.9, non damage error is30, which is the highest active Wimbledon8strong players scoring efficiency, seen from the winner/non hand errors ratio1.06, Wimbledon8athletes with minimal error and obtain more stability winner; Australian Open and French Open Top8athletes is low, at the Australian Open and French Open technical, tactical play under the stability compared to Wimbledon becomes relatively key. Therefore, the training and competition can start from the analysis of different site field characteristics, looking for opportunities in the competition and take the initiative to start pressing attack, like Wimbledon stadium8athletes with minimal errors and acquisition points winning more. |
