| Nowadays,the problem of myopia is becoming more and more serious in our country,and it is becoming younger.The prevention and control,treatment,life and physical health problems of myopia children have seriously affected their learning,life and development.In June 2018,the National Health Commission reported that the myopia rate of children and adolescents in China has ranked first in the world.On August 30 of the same year,the Ministry of education,together with the National Health Commission and other eight departments,formulated the implementation plan for comprehensive prevention and control of myopia among children and adolescents,which has attracted great attention to the problem of vision health among children and adolescents in China.Thus,the prevention and control of myopia among children and adolescents has been upgraded to the national strategic level.At the same time,the implementation plan of comprehensive prevention and control of myopia for children and adolescents also clearly emphasizes that physical exercise should be strengthened for primary and secondary school students to ensure more than one hour of physical activity time in school every day.In this study,the prevention and treatment of children's and adolescents' myopia is the main starting point,sports activities to alleviate myopia as the main means and dynamic vision can affect the development of static vision as the theoretical basis.The cheerleading project is selected as the research content to explore the impact of dynamic vision intervention program on children's and adolescents' dynamic vision and static vision in the process of cheerleading practice.To provide the operation path and method for the closed movement to improve the myopia of children and adolescents,and to serve the national strategic goal of prevention and control of myopia of children and adolescents.Objectives:1.Prepare exercises suitable for elementary school students,and at the same time be able to combine dynamic vision with internal scientific,standardized and reasonable cheerleading exercises.2.To verify the effect of the cheerleading exercise program combined with the dynamic vision task on the dynamic and static vision of the practitioner and the effect of vision rehabilitation on myopic patients.Method:Select the content of cheerleading exercises suitable for elementary school students,and combine dynamic vision tasks based on cheerleading exercises,so as to mobilize the use of dynamic vision during cheerleading exercises and develop a plan.A total of 39 children with myopia in the fourth grade of Dongshan Experimental Elementary School in Suzhou City,Jiangsu Province were screened for 4 months.Three dynamic and static vision measurements were taken before,during,and after the experiment.SPSS 20.0 was used to measure the three measurements.conduct statistical analysis.Results:1.In the cheerleading exercise program combined with dynamic vision tasks,students can actively mobilize the use of dynamic vision.Dynamic vision training has been fully incorporated into the changes in students' physical movements and the relationship between students and students,students themselves and space,and students and teachers.The content of the exercise program is in accordance with the principle of gradual and orderly learning,and the students' acceptance of the program is high.2.There was a significant change in dynamic vision(P<0.05).The comparison between pre-test and mid-test(0.438±0.216),post-test(0.498±0.249)and post-test(0.498 ±0.249)There were significant differences in post-tests(P<0.05),and there was no significant difference in mid-tests and post-tests(P>0.05).There was no significant difference in dynamic vision between boys and girls(P>0.05).At the same time,in the multiple comparison analysis of boys and girls,it was found that the contrast difference between the pre-experiment and the mid-experiment measurements was significantly higher than the mid-experimental test and post-experimental test.3.There is a significant difference in static visual acuity changes(P<0.05).The static visual acuity level is gradually increased in the mean comparison(pre-test:4.526 ± 0.245,mid-test:4.615 ± 0.257,post-test:4.741±0.241)).At the same time,there were significant differences between the pre-test,mid-test and post-test of static vision in multiple comparisons.There was no significant difference in static vision between boys and girls(P>0.05).And when multiple comparisons were made between boys and girls,there was a significant difference between the three test results for both boys and girls(P<0.05).4.Before the experiment,no students with vision higher than 5.0 were found.After the experimental intervention,11 people(28%)had a vision level of 5.0 or higher.Conclusions:1.The cheerleading exercise program combined with dynamic vision tasks is suitable for elementary school students to learn,easy to learn,easy and fun.This solution can naturally and frequently mobilize the dynamic vision of the practitioner.and perform vision exercises during the process of learning cheerleading.2.After the intervention,the dynamic vision of students was generally improved.At the same time,it was found that the effect of dynamic vision change in the early stage of the experiment was more obvious than in the later stage.Therefore,it is concluded that cheerleading exercises combined with dynamic vision tasks can effectively improve the dynamic vision level of students,and the trainers should grasp the early stages of training,and strengthen the stimulation of the dynamic vision of the practitioners at this stage.3.Cheerleading exercises combined with dynamic vision tasks can improve students' static vision without gender differences.At the same time,the improvement of static vision is showing a continuous upward trend,which is suitable for students'long-term practice.4.Some myopia patients can successfully cure myopia problems through this program,restore vision health,and get rid of myopia glasses. |
