Research On The Physical Characteristics Of The Tennis Students In Xi’an Institute Of Physical Education

Objective: To study the physical fitness of tennis special students in Xi’an Institute of Physical Education by carrying out physical fitness test and tennis competition for 30 special students of physical education department of Xi’an Institute of Physical Education.At the same time,the paper summarizes the research results of the previous research literature,draws lessons from the previous research results,combined with the Xi’an Institute of Physical Education special students of some physical fitness research,get the appropriate conclusion,to develop or improve the tennis special physical training system,cultivate excellent tennis players Provide the theoretical and practical basis for reference.Methods: The athletes were 30 students of the Department of Physical Education and Sports(male)for the Xi’an Institute of Physical Education.The age of the 30 students was about 20-23 years old.One of the sophomore to senior tennis students were divided into experimental group 1,experimental group 2,experimental group 3,with the same level of tennis skills,familiar with the rules of the game,as well as tennis proficiency in all kinds of skilled applications.Through the analysis of some of the physical characteristics of special students in different grades,the paper analyzes the different characteristics of students ’physical fitness and the influence of physical factors in special students’ competition.Results: The test group 1 performed better in explosive power,strength endurance,flexibility and aerobic endurance.The test group 3 performed better in sensitive and short-range accelerated start-up,and in group 2,Middle,no special outstanding performance.Specifically in the sensitive and short distance to accelerate the start and stop,there are picking up the ball back,lateral sliding round trip and hexagonal foot and feet jump three projects.In the three projects,the average time is the least test group 3,and the other two groups of test group difference of about 1 second,indicating that the test group 3 in the tennis special physical sensitivity and short distance acceleration ability.In the muscle strength and endurance have sit-ups and push-ups test,the best in these two tests are the test group 1,1 minute test than the other two groups of results more than 5-10,indicating that the muscle Strength and endurance far beyond the other test groups.In the explosive force and force transfer test,the average of the three groups before the test group were 10.25 m,10.06 m,10.01 m or less,compared with the test group 1 results better than the other two groups.But the test group 1 is far superior to the other two groups after the drop.In the vertical test,the average score of test group 1 was the highest,which was about 0.1m higher than that of the other two groups,indicating that the lower limb muscle explosive force of test group 1 was stronger.The flexion of the test group was measured by the flexion test.Test group 1 the highest average score,the worst score than the test group 2 2.82 cm that test group 1 better physical flexibility.In the aerobic endurance test of 3000 m,the average time of test group 1 was 10.62 min,followed by test group 2,the score was 10.81 min,the test group 3 was the longest and 11.35 min.Combined with the explosive test,indicating that the test group 1 in the explosive and endurance are more prominent.Conclusion:(1)Combining physical fitness test and game data,it can be found that with the increase of learning time,the ability of tennis special students to improve the ability of short distance and body balance gradually improve,that is,speed quality and sensitivity to improve.But the strength,endurance,flexibility and quality of varying degrees of decline,especially the decline in the quality of endurance greater.(2)individual sophomore students better physical fitness,but learning tennis time is shorter,can not play physical advantage,the game can not take the initiative,resulting in more mistakes.Senior students,although the technology is better,but poor endurance,if the game time is longer,can not maintain a good competitive state.
