The Research On The Characteristics Of Techniques And Tactics Of Elite Female Tennis Singles On Clay

This article takes four elite female tennis players as the research objects and adopts literature and data method, video statistical method, mathematical statistical method, logical analysis method, from five aspects inculding the basic unit of competitive process, the technology application, the space-time distribution of appling technical and tactical, the technical and tactical of serves and reserves games analyse the features of the technical and tactical on clay game, the results show that:1. The order rank of the ending of the distribution frequency in the competitive basic unit of the process is:two pats, three pats, four pats, five pats, six pats, seven pats, one pats, the ending frequency gradually decreases following the increasing of pats, the sum of ending the frequency of the first four pats is 45.4%, the sum of ending the frequency from five pats to ten is 39.8%, the sum of ending the frequency after ten pats is 16.8%.2. The characteristic of using space the first is backcourt and middle field, the second is midcount and left field, the third is frontcount and right field.The scores are the most at backcount, losing of points are the most too; the scores are more than the loss of points at frontcount and midcount the scores at midcount are more than left and right field; losing of points at midcount are lower than the left and right field.3. The rate of every placement of first serve is different, but the success ratio of sending to the angles and the exterior angles are higher than sending to the midcount; the ratios of every second serve of all players sending to the placement of midcount are the highest, but the success ratio is lower than sending to the interior angle and exterior angle. The utilization ratios of every player at all stages of different tactics are different, but the success ratio at serve tactical stages is higher than that at stand-off tactical stages. Most of pleyers score higher at serve tactical stages than that at stand-off tactical stages, but loss of points are concentrated at stand-off tactical stages.Score by the initial attacks is more than that by unforced error of opponents, the loss of points mostly come from their own unforced errors.4. Receive the first serve, not only the ratio of sending to the opponent’s out-side placement is the highest, but also the success ratio is the highest; Receive the second serve, the ratio of sending to the opponent’s in-side and out-side placement is higher than sending to the opponent’s middle-filde placement, while the success ratio of sending to the opponent’s in-side placement and middle-filde is higher than sending to the opponent’s out-side placementThe utilization ratios of every player at all stages of different tactics are different, but the success ratio at stand-off tactical stages is higher than that at serve tactical stages. Scores are concentrated at stand-off tactical stages, but loss of points are concentrated at reserve tactical stages.Styles of score are different among the plyers, but loss of points are concentrated at unforced error of themselves.
