A Comparative Analysis Of The Technical And Tactical Characteristics Of Tim's Clay And Hard Courts

Using literature data method,mathematical statistics method,video analysis method and comparative analysis method,the technical and tactical differences of Tim in clay and hard courts were analyzed.The conclusions are as follows:(1)During the service stage,Tim's technical and tactical differences in clay and hard ground are mainly reflected in: Tim serves faster in the hard ground,but mainly spin and change;in the landing point of the serve,Tim doubles in the hard field to the opponent,while in clay,the middle and inside and outside points are more balanced.At the same time,Tim has a more prominent attack in the hard serve stage,the first shot scoring rate,the third shot scoring rate are significantly higher than the clay court,while Tim is mainly steady and variable,the second shot scoring rate is significantly higher than that of the hard court.(2)in the receiving stage,Tim in clay and hard tactical differences are mainly reflected in: Tim in clay receiving quality,especially for receiving depth control,Tim in the clay court serve back probability is significantly higher than the hard court,which also directly leads to Tim in clay scoring rate is significantly higher than the hard.On the second set,Tim was more active on hard shots and aggressive,while on clay shots,Tim mainly uses the upper spin Angle to move his opponent.(3)In the stalemate phase,Tim's technical and tactical differences in clay and hard ground are mainly reflected in: as a whole,Tim took more shots on clay than hard,Long multi-bat rounds at 4-8 and 9 and above were significantly higher than hard ground;Judging from the use of various technologies,Tim is more abundant on clay,After the bottom line is stalemate,Tim usually uses small and high balls to mobilize opponents,And the Internet is also more active,But Tim doesn't score high in front of the clay net;And Tim is more solid at the bottom line of the US Open,With the bottom line forehand and backhand mainly,Other techniques are less frequently used,I is also very cautious about surfing the Internet,Therefore,Prenet scoring is more efficient.
