Experimental Research On The Physical Health Development Of Primary School Students By Different Combined Exercise

In recent years China has increasingly attached great importance to the physical health of elementary students and enacted a broad spectrum of rules and regulations in an effort to improve the supervision of students’ physical health. This paper focuses on how the different exercise combinations exert influence on physical health of elementary students from the perspective of experimentary study,and has an in-depth discussion on the methods of extracurricular physical activities with high quality and efficiency through the application of different excercise combinations on student’s extracurricular physical activities, and arouse the interests of students in participating in sports activities and their lifelong sports consciousness, provide the students with guideline to excercise right methods, improve its own body shape, physique and quality, promote the school sports education reform, and provide important theoretical basis for the decision of research content and direction of this paper.This paper includes conducting research on the different exercise combinations of 48second-grade students from Beijing Yutaoyuan Elementary School Ten indicators such as body shape, function and quality on the basis of National Physical Health Standard will be exercised in assessing the effect of plans of different exercise combinations on students’ physical health in experimental group and control group.The experiment results showed that:1.Compared with the condition before the experiment, after the experiment, the differences of male and female students’ body shape index of height, shoulder, abdomen skin fold thickness and fat percentage in experimental group and control group are significant. It shows that two kinds of different ways of physical exercises have played the positive role in improving the body shape of elementary school students.2.After the experiment, the body function(lung capacity index) in experimental group and control group both had an increase. However, compared with the control group, the body function of male and female students in experimental group grew more. Meanwhile,the results in boy students showed a significant difference and girl students had no difference. This results suggested that different combinations of physical training plan in experimental group tended to have a better effect in improving the body function of elementary students.3.The experimental group and control group after experimental male and female five physical quality test results show that the experimental group male and female performance slightly better than the control group male and female, and cross quadrant jump very significant differences in test scores.The results indicated that these two different combinations of physical exercise plan both had a positive effect on the improvement of body quality of primary school students, and the plan in experimentalgroup tended to have a better effect.4.The different combination of the experimental group on the practice of relative control scheme can arouse the enthusiasm of elementary school students to participate in physical exercise, the scheme which contains rich content and new method is popular with the students and improves their interest in physical exercise.The extracurricular sports activity of the exercise scheme can improve the physical health of students more effectively.
