Experimental Study On The Effect Of Plyometrics Training On The Effect Of Tennis Flat Serve Of Physical Education Tennis Students

The flat serve is a very important technique in tennis and an indispensable means of attack for excellent tennis players.The tennis flat serve has the characteristics of fast speed,strong power and strong scoring ability.It can create good attacking conditions for the server in the match,and even score directly.Therefore,the improvement of tennis flat serve ability is very important for the improvement of tennis players’ competitive level.In order to have a good tennis flat serve technology and improve tennis flat serve ability,we need to rely on scientific and efficient training methods and means.Plyometrics training has been gradually added to the training of many sports from the early 20 th century.In recent years,it has also been adopted by many ball games.However,it is rarely applied in tennis.Therefore,what is the effect of plyometrics training on tennis flat serve technique? Which is the most suitable tennis flat serve plyometrics training means? What is the cause of plyometrics training affecting tennis flat serve technique? It is worth exploring in depth.In this study,literature review method and other methods were used to optimize the appropriate rapid stretching composite training means,and the optimal rapid stretching composite training means was used in teaching training,and the effect of rapid stretching composite training was verified through the teaching training effect.This study randomly selected 14 students from the special tennis team of the physical Education Department in 2019 as the research objects,with8 students in the experimental group and 8 in the control group.There was no significant difference between the two groups,and the teaching and training time was 8 weeks.The experimental group trained by plyometrics training means,the control group trained by general resistance training means.Through 8 weeks of training,the two groups of students were tested for the special quality of tennis flat serve(throwing medicine ball in kneeling position,standing long jump,one-minute rope skipping),kinematic analysis,tennis flat serve effect test(serve stability,serve accuracy,serve speed)and other tests.By comparing the test results,the following conclusions were drawn:1.After the experiment,the special students in the experimental group improved their special quality far more than the special students in the control group.The score of kneeling over the top throwing medicine ball increased by 26.9%,the score of Standing long jump increased by 17.8%,and the score of one minute rope jump increased by 20.1%.2.After the experiment,the center of gravity of the special students in the experimental group decreased by 0.15 m compared to the control group when serving flat shots,with a difference of 0.18 m in the distance of push and extension.There was no significant difference in the length of push and extension between the two groups of students,and the experimental group of students had stronger ability to push and extend their lower limbs.3.After the experiment,the special students in the experimental group scored 9.1 points on the flat serve landing test,with a success rate of 30.1 points and a flat serve speed of 166.57km/h.Except for the score of the landing point test,the success rate and speed of the flat serve of the experimental group’s special students were much higher than those of the control group’s special students.After analyzing and summarizing the experimental results,the following conclusions were drawn:1.After the experiment,the experimental group’s specialized students’ tennis flat serve had a faster ball speed and higher success rate,and the overall flat serve effect was higher than that of the control group.Pylometrics training is more conducive to improving the flat serve effect of tennis specialized students.2.Pylometrics training training has improved explosive power and body coordination ability,making specialized students have stronger muscle explosive power,more stable flat serve movements,and smoother body power transmission,thereby improving the effect of flat serve.3.In the training of tennis flat service,attention should be paid to the comprehensive development of various physical qualities to meet the needs of special techniques for physical qualities,and training means should be selected according to the special Feature selection of tennis flat shot service techniques to make full use of the migration effect.
