Research On The Reference Curve Of Physique Health Index Of Primary And Middle School Students In Jiangsu Province

BACKGROUND&OBJECTIVE:The physical fitness indicators such as body shape,physical quality and physiological function of the students have certain regional characteristics,and the reference value of different age of students in different regions is more specific.In this study,the physical health monitoring data of students in Jiangsu Province in 2015 were used to screen the students 'physical health evaluation index.The LMS method was used to fit the reference value of the percentile of the 7-17 year old students' physical fitness index.L,M,S curve And percentile curve,and with WHO international standards for comparative analysis,and ultimately the formation of a complete set of Jiangsu Province,the evaluation of students' physical health standard system.With a view to increasing the scientific,integrity and practicability of the physical health evaluation system in Jiangsu Province.In practice,it provides the evaluation tools for Jiangsu students 'physical health promotion,which is helpful for the relevant administrative departments to understand the basic situation and development trend of Jiangsu students' physical health,and provide scientific physical health evaluation means for individual students,and establish suitable physical fitness for other provinces Evaluation system to provide reference.Methods:This study uses the literature data,mathematical statistics method,LMS method,from the perspective of fitting growth curve,the 2015 Jiangsu Province,primary and secondary school students physical fitness monitoring data were divided into age-specific curve.The LMS method was used to fit the reference value of physical health related indexes of male and female students aged 7-17 years in Jiangsu Province.P3,P5,P10,P50,P90,P95,P97 percentile curve.Research result:(1)The LMS curve and the percentile curve of the primary and secondary school students in Jiangsu Province are within the allowable range,and the curve fitting effect is better.LMS curve and physical health of the indicators of percentile curve fitting results with the development of students' physical fitness in line with the law,the curve of the fit is scientific and feasible.(2)Through the fitting of LMS curve and percentile curve of the students'physical fitness test in Jiangsu province in 2015,it can be concluded that,in addition to this index,Jiangsu Province primary and secondary school students in physical Test other indicators of the results have increased with age;in addition to seat flexion,strength indicators,the other indicators of the boys are better than girls.(3)With age,body shape indicators,height,weight,BMI with age and growth,height growth rate of the largest,and 7-12 years of growth peak.In the body function index,the pulse rate decreased slowly with age.The diastolic blood pressure and systolic blood pressure of boys and girls all increased slowly,and the increase rate of male and female students increased with age,and the increase rate was higher than that of girls The Physical fitness indicators,50-meter run,long-distance running,standing long jump three indicators of the results are increased with age,boys to improve the degree than girls;seat flexion boys and girls percentile curve is gentle growth,girls good grades In the boys;strength of quality,with age,the decline in the strength of boys,girls slow growth.(4)Jiangsu Province students in the physical test indicators in the body shape higher than the WHO standards and other provinces of the standard;physical fitness,body function indicators and national physical health standards,far higher than the national standard and grid,in good rate,excellent Rate,with gender,sports differences,the specific performance:boys in the 50-meter run,standing long jump show and other explosive,power-type sports have obvious advantages,and girls in the flexibility of the seat of the pre-flexion project In the obvious advantages.conclusion:The P5,P10,P50,P90,P95,P97 quantile reference values of children and adolescents in various age groups in Jiangsu Province were established,and the growth curves of different indexes were obtained.To fill the lack of Jiangsu Province,the evaluation of physical fitness standards for children aged 7-17 years of age for children and adolescents to provide a more accurate reference standard for Jiangsu Province,physical health promotion practice and individual health evaluation of students have a high practice value.
