An Experimental Study On The Effect Of Baseball Throwing Technique On Serving Technique Transfer Of Tennis Students In Sports Colleges

Background and purpose: Tennis serving is a technique that requires high coordination of upper limbs,lower limbs,waist and abdomen strength.Only by coordinating the whole body can the best hitting effect be produced.The trajectory and power characteristics of baseball throwing are very similar to those of tennis serving,both of which belong to "whipping".Therefore,the effect of positive transfer can be produced by integrating the training of baseball throwing technique into the teaching of serving technique of tennis students.This is a good inspiration for improving the teaching efficiency of tennis service technology.The purpose of this integrated technology teaching is to improve the success rate,accuracy and strength of the students’ serving,as well as their interest in the tennis serving technology.It can provide more ideas for the teaching and training of tennis service technique.Research objects and methods: The research adopted the method of literature,expert interview,questionnaire,teaching experiment and mathematical statistics.Twenty male students from the special tennis class of Social Sports Guidance and Management major of Guangzhou Institute of Physical Education in 2019 and 2020 were selected as the experimental subjects.Before the experiment,according to the results of the service test and the basic physical fitness test,the subjects were divided into the experimental group and the control group,with 10 people in each group.The eight-week controlled experiment was conducted.Once a week,each training lasted for 90 minutes.The experimental group adopted the method of integrating the training of baseball throwing technique into the teaching of tennis serving technique,while the control group adopted the traditional teaching method.After the experiment,the success rate,accuracy rate and strength data of the test subjects were collected again.Finally,SPSS19.0 software was used for statistical analysis of the experimental data.The paired sample T test was used for intra-group comparison before and after the experiment,and the independent sample T test was used for inter-group comparison.Research results:(1)There were significant differences in the success rate of serve between the experimental group and the control group before and after the experiment,but the success rate of serve in the experimental group increased more.The success rate of serving in the experimental group increased by 23 percent overall,compared with 11 percent in the control group.(2)In terms of service accuracy,the comparison results before and after the experiment in the experimental group were P < 0.05,indicating a significant difference.In contrast,the accuracy of the serve in the control group was P >0.05,indicating no significant difference.(3)In terms of service power,the comparison results of the experimental group before and after the experiment P < 0.05,indicating that there are significant differences in service power.In the control group,P > 0.05 showed no significant difference in the index of service power of the second landing point c.(4)In terms of students’ interest and attitude,P values of the experimental group before and after the experiment in five dimensions were all less than 0.05,while only one dimension of the control group was less than 0.05.That is,there was significant difference in the experimental group students’ interest and attitude,while there was no significant difference in the control group.Conclusion:(1)Integrating baseball throwing technique training into tennis serving technique teaching has positive transfer effect on improving the success rate of students’ tennis serving.(2)Integrating the training of baseball throwing technique into the teaching of tennis serving technique has a positive transfer effect on improving the accuracy of students’ tennis serving.(3)Integrating the training of baseball throwing technique into the teaching of tennis serving technique has a positive transfer effect on improving students’ serving power.(4)Integrating the training of baseball throwing technique into the teaching of tennis serving technique has a positive transfer effect on improving students’ interest in learning tennis serving technique.
