Research On Regional Characteristics Of Physical Health Of Primary And Secondary School Students In Sichuan Province

With the enhancement of China's comprehensive national strength,the physical development level of primary and secondary school students has been improved accordingly.However,due to the influence of personal,family,social and other factors,students' physical health is facing practical problems such as decline.At present,the change law of physical health from the perspective of time and the regional distribution characteristics of physical health from the perspective of region are not clear.In addition,the exploration of the influencing factors leading to the change of students' physical health is not enough to scientifically and accurately guide the improvement of students' physical health.Therefore,it is necessary to conduct a more in-depth study on the physical health characteristics of primary and secondary school students.In this study,the physical health test results of students in primary and secondary schools in Sichuan Province from 2016 to 2020 reported by Sichuan student physical health big data center and the random inspection and review data of physical health of students in Sichuan Province in 2019 and 2020 from the national local joint Engineering Laboratory of system credibility automatic verification of Southwest Jiaotong University are used as the research data sources,using the methods of literature,mathematical statistics By means of expert interview and comparative analysis,this paper analyzes and studies the current situation and regional characteristics of physical health of primary and secondary school students in Sichuan Province,and puts forward countermeasures to improve the current situation of physical health of primary and secondary school students,so as to provide reference basis for scientific decision-making of educational administrative departments.The research shows that: 1 In recent five years,the overall level of physical health of students in Sichuan Province has improved,the excellent rate and good rate have increased slightly year by year,and the overall trend is good.2.In the past five years,the overall average score of students' physical health in the whole province needs to be improved urgently.The total average score of students' physical health in Chengdu ranks first in the whole province for five consecutive years.The total average score of students' physical health in Neijiang City and Mianyang City has increased continuously in the past five years.The average score of students' physical health in ethnic minority areas has decreased for two consecutive years,and that in eastern Sichuan has decreased for four consecutive years,The overall average score of students' physical health in Guang'an and Guangyuan is poor,which has been at the lower level of five regions for five consecutive years.The overall average score of students' physical health test in Chengdu alone reached a good level in 2019 and 2020,and the overall average scores of other cities and prefectures were qualified.3.In the past five years,there has been a significant difference in the excellent rate of physical health among students in cities and prefectures across the province.Chengdu has ranked first in the excellent rate for five consecutive years.The excellent rate of physical health among students in Ganzi Prefecture,Aba Prefecture,Panzhihua City and other regions is better,and the excellent rate of physical health among students in Northeast Sichuan and southern Sichuan has been lower for many consecutive years.In the physical health test in 2020,the excellent rate and pass rate of 12 cities and prefectures in the province decreased compared with the previous year.The total average score of Ganzi Prefecture,Zigong City and Neijiang City decreased for two consecutive years,with the largest decrease of-3.19% in Guangyuan City.The excellent rate of students' physical health test in Chengdu,Mianyang City,Bazhong City and Guang'an City increased year by year for five consecutive years,The maximum interpolation of excellent and good rate of cities and prefectures is 30.54%,and the difference of physical health level between regions is significant.4.In the past five years,the qualified rate of students' physical health in the province has decreased steadily.Chengdu has ranked first for five consecutive years,and the qualified rate in eastern Sichuan and southern Sichuan has ranked lower.In 2019,the qualification rate of 10 prefectures,cities and prefectures in the province decreased compared with the previous year,and in 2020,the qualification rate of 16 prefectures,cities and prefectures decreased compared with the previous year,including northwest Sichuan,Chengdu Plain and inner cities in southern Sichuan.5.The physical health status of students in plateau,remote areas and ethnic minority areas needs attention from all parties.According to the data from 2016 to 2020,the physical health level of students in Aba,Liangshan and Ganzi prefectures has declined to varying degrees.Results: 1.In the consistency test,1000 meters and one minute rope skipping have good consistency;In the six items of height,weight,vital capacity,sitting posture,forward flexion,sit ups and 800 meter running,the results of spot check and review were significantly better than the data submitted;Standing long jump,pull-up,50 m running and 50 m X8 round-trip running were significantly worse than the submitted data.In the t-test results,it is found that 11 projects in Ziyang City,the first in the province,have good consistency,10 projects in Guangyuan City,Bazhong City and Luzhou City have good consistency,and Neijiang City,Zigong City,Leshan City and Meishan City rank relatively low.2.The local economic level directly affects the healthy development of students' physique.The higher the per capita GDP,the higher the students' physique health level.However,in terms of flexibility,endurance and explosive power,the score of mountainous areas is higher than that of areas with relatively high per capita GDP,indicating that the students' physique health level is greatly affected by topographic factors and presents obvious regional characteristics.Cities with higher per capita GDP are more prone to obesity and overweight.3.Local education expenditure can not significantly improve students' physical health level.Through the correlation analysis between students' physical test scores in 2019 and 2020 and corresponding regional education expenditure,it is found that the higher the education expenditure,the lower the average score of students' physical health in prefectures,cities and prefectures,and the lower the excellent rate.4.Altitude has a direct impact on the physical health test results.On the one hand,although the students' physical health test results increase with the increase of altitude,the physical health level decreases when the altitude exceeds 3000 meters.
