An Experimental Study On The Effect Of Unilateral Lower Limb Strength Training On The Stability Of Forehand And Backhand Strokes Of Tennis Students

Sports colleges and universities serve as the cradle for training talents in the sports industry,and tennis-specific students are the main force that will drive the development of tennis in China in the future.The depth of their understanding of tennis teaching and training will have a profound impact on the development of tennis in China.Tennis is a net confrontation sport,which requires players to run back and forth repeatedly during the game,and the breaking of body balance brings challenges to the stable forehand and backhand strokes,and has long troubled tennis students.The paper combines the characteristics of the movement pattern of tennis,and tries to verify the effect of lower limb unilateral strength training on the stability of forehand and backhand stroke of tennis students in sports colleges through training interventions,so as to provide substantial reference for the teaching and training of tennis courses in sports colleges.The study was conducted by using literature method,expert interview method,questionnaire method,experimental method and mathematical and statistical method.Twenty students in the tennis special class of class 2020 of the Wuhan Sports College Tennis Academy were randomly selected as the experimental subjects.A 10-week lower limb strength training program was developed and carried out.Through the comparative analysis of the relevant data between the two groups of students before and after the experiment,we learned that:(1)After 10 weeks of bilateral strength training in the control group,the static balance ability of the control group was p<0.01,indicating a very significant difference before and after the experiment.The dynamic balance ability indexes showed a highly significant difference between the left lower limb composite score and the right lower limb composite score before and after the experiment,i.e.p<0.01.There were highly significant differences in forehand stroke depth,backhand stroke depth,depth stability score,total depth score and total accuracy score.There were significant differences in forehand accuracy,backhand accuracy,and accuracy stability scores(P<0.05).(2)After 10 weeks of unilateral strength training,there were highly significant differences between the experimental group and the students in the static balance test and dynamic balance test,i.e.,P<0.01.The P values of depth and accuracy of forehand and backhand were less than 0.01,which were highly significant.(3)The static balance ability of the experimental group and the control group were very significantly different after the experiment(P<0.01).There was a significant difference between the YBT test scores of the experimental group and the control group after the experiment(P<0.05).There was a highly significant difference(P<0.01)in the total score of forehand and backhand stroke depth and a significant difference(P<0.05)in the total score of accuracy in the post-experimental ITN test.The following conclusions were drawn from the study:(1)Unilateral strength training and bilateral strength training have a positive effect on the improvement of static balance ability of tennis special students,but in the form of unilateral strength training has a better effect on the static balance ability of students.(2)Both types of strength training can improve the dynamic balance ability of tennis students,but unilateral strength training has a greater improvement on the dynamic balance ability of students.(3)Unilateral strength training is more advantageous to promote the improvement of forehand and backhand stroke stability of tennis students in sports colleges than bilateral strength training.
