Experimental Study On Stability Of Bottom Line Forehand Stroke Of Teenagers Tennis Players By Suspension Training

Tennis is a sport with strong competition,delicate movements,complicated techniques and tactics.It requires high hitting depth and accuracy.In the high level tennis match,in order to hit the high quality depth and accuracy ball,the high quality hitting ball not only requests the hitter to control own body movement,but also requests the fast movement and the accurate judgment landing spot.In tennis,forehand stroke is the most basic action,and it is also the skilled movement that the most practical and easy to control the ball.Therefore,young tennis players should make full use of different training methods to improve the training level in order to win the game.The suspension training is a kind of training method which borrows the equipment and lets some part of the body be in the unstable state.The athlete relies on the muscle strength to maintain the body balance and the stability.This study explores the effect of suspension training on the stability of baseline strokes of junior tennis players through two training programs: suspension training and general strength training.It provides a theoretical basis for the development of tennis and the improvement of the technical level of Chinese tennis players.This paper used literature method to collect the relevant research on suspension training and forehand hitting stability,and it usedd interviews with experts and questionnaires to determine the content of training.Twelve players from the Tai'an junior tennis team were divided into several groups and trained for eight weeks.In this study,the subjects were divided into control group and experimental group on the basis of the score of hitting depth and accuracy in ITN.The experimental group used routine training plus suspension training in physical fitness training,and the control group used routine training plus general strength training.Before and after the training,the two groups of subjects were tested on hitting strength and hitting accuracy,and the data were recorded.The obtained test data are statistically analyzed by mathematical statistics method.Results: 1.Before and after the experiment,the hitting depth of the experimental group was 30.83 points.The hitting depth of the control group was slightly higher than that of the experimental group.The hitting depth of the experimental group was 31.83 points.There was no significant difference(P>0.05).The hitting accuracy of the experimental group was 32.67 points.The hitting accuracy of the control group was slightly higher than that of the experimental group,The hitting accuracy was 33.00 points.There was no significant difference(P>0.05).2.Before the experiment,the score of hitting depth of juvenile tennis players was 30.83 points.After the training,the score of players increased to 43.00 points,and the difference was statistically significant(P<0.05).The score of hitting accuracy of juvenile tennis players was 32.67 points.After suspension training,the players' score increased to 43.67 points,and the difference was statistically significant(P<0.05).3.Before the experiment,the score of hitting depth was 33.83 in the control group.After the training,the score increased to 35.17.There was no significant difference(P>0.05).The score of hitting accuracy of juvenile tennis players was 33.00 points.After the training of common strength,the players' score increased to 36.67 points.There was no significant difference(P>0.05).4.The average score of hitting depth in the experimental group was 43.00 points,which was higher than 7.83 points in the control group(P<0.05).The average score of hitting accuracy in the experimental group was 43.67 points,which was 0.700 higher than that in the control group(P<0.05).
