Experimental Study On The Effect Of Leg Strength Training On The Balance Ability Of Junior High School Students

Since the founding of new China for more than 60 years,China’s national economy has shown a rapid development trend,people’s living standards and quality of life gradually improved.And in the material rich,fast pace of life today,the health of the people more and more attention,and the physical and mental health of young people is not only a matter of family concern,but also an important issue of national concern.Since the reform and opening up,the Ministry of Education has been growing emphasis on the development of its sports,but with the rapid development of science and technology,transportation and other aspects of people’s daily work to show a low trend of labor,and from the Ministry of Education to young people The results of physical monitoring to see,now the community of young people will appear a variety of physical and mental problems,many students outbreak of the ability,endurance,muscle power and other qualities are rapidly reduced."Soft" refers to the weak;"hard" on behalf of the joint hard,stiff;"stupid" is due to long-term inaction caused by the body is not the body of the "soft" coordination.The long way to go,it caused its athletic ability and technical ability to grasp the increasingly weak,and balance is to maintain the basis of the movement posture is to complete a variety of actions to ensure that any action,need to balance the body as a support.Objective:In this paper,the general junior high school students as the research object,the leg strength training as a way to improve the balance,from the junior high school students experimental group and the control group before and after the test results and balance of changes in the situation to find the legs Strength training on the balance of capacity,how to improve the balance of ability to find a more scientific and feasible method.Methods:In this paper,the use of literature,comparative analysis,experimental methods and mathematical statistics and other methods to explore the content of its experimental study.The course was randomly divided into 20 experimental groups(10 female students and 10 female students),20(10 male and 10 female students)in the control group,and randomly selected 40 students from the middle school students of Tianyi Riverside Middle School in Xi’an.And its body shape,standing long jump and balance ability and other indicators before and after the test test.The experimental group and the control group test the same test and test the standard,but the experimental group in the two sections of the physical section of the week to join the special leg strength training,2 times a week,every 20 minutes;while the control group is not specialized Of the leg strength training,mainly in accordance with the school’s syllabus for teaching.The contents of the test are:body height,weight,standing long jump,closed eyes single foot,single foot before the soles of the feet stand,crane test and eyes closed a total of seven data.Conclusion:The rigorous lower limb strength exercise has a good effect on improving the balance ability of junior high school students.
