Shandong Institute Of P.e.and Sports Two Different Gait Analysis Of The Bottom Line In Tennis Forehand Stroke Effects

Today's best tennis player in the complex of high strength,technique as well as to the physical demands higher competition condition,the gait of the flexible use of guarantee for the hitting effect is plays a vital role,the athletes according to particular case is particular analysis of the game,to be in the shortest possible time to timely adjust transform mobile footwork,achieve the optimal effect,if the athletes use of footwork movement is not reasonable,effective complete it will be difficult for us to ensure that strokes,so any ground position,to any nature and any height to ball player is flexible coping,this article through to compare the effects of different footwork movement.This paper USES literature,expert interview,mathematical statistics and comparative analysis research method,the two different gait bottom line in tennis forehand stroke effect comparison.Use independent sample t-test analysis way and they in fixed route and the ball in different lines,eight athletes in the return time,success rate,target respectively to compare the accuracy and depth.Through the study found that athletes after using different footwork to hit the ball in the return time,success rate,depth and target accuracy is different,by watching the tennis match test video,visiting experts,coaches,data access,etc.,to the point of view that the two different footwork drive effect,test to study the way and they respectively study of effect of bottom line forehand footwork,and sums up the way they and movement characteristics and training means,for training and teaching of the coaches and the athletes' ability to provide the reference.Through the experimental results the following conclusions:(1)when simulating swing 2 m way and they return time no significant difference,the 4 m way and time after they return no significant difference;(2)the bottom line on the forehand return time is: 2 m way and they return time no significant difference,the 4 m way and time after they return no significant difference;(3)the bottom line on the forehand the success rate for: 2 m distance way mobile shots success rate than the 2 m distance after they move the success rate ishigher;And 4 m distance way moving when hitting the highest success rate;(4)the bottom line on the forehand shot on target: athletes at 2 m distance is the same way movement and they move the shot;4 m distance after they than 4 m distance way shooting small;(5)the bottom line on the forehand depth: 2 m distance,way to hit the ball deep depth is significantly higher than after they hit the ball.Higher than 4 m distance,they shot the depth way depth.
