Research On Characteristic Of Technique And Tactics Outstanding Man's Serve And Reserve In 2006 Shanghai Master Cup

In recent years,along with tennis rapidly develop,the tennis technique and tactics have had very big change.Serve and reserve occupied the important position in the competition similarly have had a very big change in the technique and tactics aspect,needed our earnest research to the stage of serve and reserve technique and tactics characteristic.This research take in eight players who take part in the 2006 Shanghai master cup as the object of study,use literature research technique and so on material law,the mathematical method of average,expert talk law and observation video recording law,to study the stage of serve and reserve of 14 competitions,and makes the analysis,finally draws the following conclusion.(1)Eight outstanding player's ACE ball number differences are obvious,the mean value about 8,the double fault integer about 2,the difference is not obvious;The serve direct score rate to 31.9%.(2)In the different serve area's service winning score and serve winning rate do not have the obvious difference;The percentages of first serve and second serve have obvious difference;there is obvious different between rate of first serve score and second,Should cut the second serving success ratio suitably,increases winning rate of second serve;Eight player's right areas first serves in serves in line's choice not to have the obvious difference,the right area second serves,the left area first serve,the left area second serves to have the obvious difference;The wining rate of different serve line does not have obvious difference.(3)The rate of use drive return the first serve to occupies half proportion,block and cut occupy another half;The rate of use drive return the second serve to occupies about 70%.Takes the straight line when returns the inside corner serve to account for 41.5%,Takes the oblique line when returns the outside corner serve to account for 59.5%; The deep of reserve by the baseline ball primarily,surpasses 65%.(4)The direct score rate of reserve achieve at 14.9%;The number and winning rate of first reserve and second reserve,in meets quantity which first serves and meets second serves and in the score rate have the obvious difference,although has the very big difference,but the score is not obvious difference.
