Dynamic Analysis Of Physical Fitness And Health Of Grade 1-9 Students In Jiangxi Province From 2016 To 2018

In order to implement the guiding principle of "health first",the National Standards for Students' Physical Health was implemented in all kinds of schools at all levels throughout the country in 2007.There are relatively few studies on physical health of primary and secondary school students in Jiangxi Province,and the research lacks continuity and systematicness.Therefore,through the study of the results of physical fitness test of the students of Grade 1-9 in Jiangxi Province from 2016 to 2018,conducting a field survey of some schools in various cities,analyzing the physical health condition of students,and exploring the existing problems and reasons in view of their physique,this paper can provide a theoretical basis for the improvement of the physical fitness of the nine-year compulsory students in Jiangxi Province.In this paper,the physical fitness test scores of Grade 1-9students sampled randomly from 2016 to 2018 in Jiangxi Province are taken as the research object,then their physical condition and corresponding causes are analyzed by mathematical statistics.The results are as follows:(1)the excellent rate of pupils' total performance is between0.3% and 2.2%,and the excellent rate of junior high school students is 1.6% and 3.2%;(2)the body weight and BMI index of pupils are lower than the national level for three consecutive years,while the height value of junior high school students is better than the national level for three consecutive years,and the obesity rate of junior high school boys is as high as 10.2% in2018.(3)The excellent rate of female students' vital capacity is higher,ranging from 22.1% to31.8% and that of male students from 7.9% to 24.5%;(4)the excellent rate of 50-meter performance of junior high school students is between 20.8% and 32.5%;(2)the failure rate of male students in primary school in 2017 and in junior middle school in 2018 is as high as22.2% and 20.6%,and the excellent rate of female students in primary school in 2016 is14.5%;the excellent rate of rope skipping in primary school is increasing year by year,and in2016 junior high school students.The excellent rate of standing long jump is as high as 44.8%,and the failure rate is only 7.2%;the sit-ups are mostly above the pass rate;the boys in junior high school fail in the lead-up performance,which is as high as 73.1% in 2018;the excellent rate of 50m*8 round-trip running of primary school students in 2017 is higher than that in2016 and 2018;the excellent rate of 800 m and 1000 m of junior high school girls and boys in2016 is higher than that in other two years;the passing rate of junior high school girls is higher than that of other two years.It is higher than that of boys in junior middle school.Research conclusions:(1)Total score evaluation: From 2016 to 2018,the total score evaluation of physical fitness test of Grade 1-9 students in Jiangxi Province is mainlydistributed in passing and good levels,with a low rate of excellence.The total grade of boys and girls in primary school is increasing,but it declines slightly in junior middle school.(2)Body shape: Although the growth trend of height in junior middle school is slowing down,it is higher than the national level,and the obesity rate of junior middle school students has increased;(3)Body function: vital capacity has not changed significantly in the third year of grade 1-4,and slightly increased in the third year of junior middle school.(4)Physical fitness:The speed quality of girls,the explosive power of lower limbs of girls in junior middle school,the waist and abdomen strength of boys and girls,and the upper limb strength of boys are higher than the national level.Endurance quality has increased in the past three years,but the explosive power of primary school students and upper limb strength of junior high school students still need to be strengthened.This paper gives some suggestions on the current situation of students' physique in Jiangxi Province,including strengthening leadership,highlighting publicity and education,giving full play to the comprehensive role of physical education in promoting quality education,strengthening the management and construction of physical education teachers,improving supporting facilities,adjusting the scope and weight of physical education evaluation,encouraging social sports resources to enter schools,introducing third-party professional institutions and regularly announcing students' physique to the society.
