The Trend And Grey Of The Physical Health Of College Students In Yunnan Province

As an important component of the development level of social productivity,physical health is an important symbol of modern civilization and social progress.College students are the future of the nation,also the hope of the country.Their physical health is an important indicator of the level of political,economic and cultural development of a country.Nowadays,with the development of modern society,there are more and more problems in the physical health of college students,and various countries are paying more attention to it.In this paper,the average achievement of national students' physical health standard data of Yunnan province from 2013 to 2016 are analyzed and predicted based on the literature data,mathematical statistics and grey prediction method.The test results are statistically analyzed by development coefficient,progressive coefficient statistical table,sequential dynamic graph and dynamic map of fixed base ratio.The development coefficient of each test item in the physical fitness test can reflect the developing trend of the test data.The average of progressive coefficients can reflect the development status,the standard deviation of progressive coefficient can reflect the fluctuation range of the project,and the monthly dynamic chart can reflect the fluctuation of the annual test data development.Based on the dynamic map of the test data,the test data can be used to test the route of data development.By the method of grey prediction GM(1,1)model to 2017 and 2018 national student physical health survey,the data of national student physique healthy standard test report data to estimate that about 2017 forecast result verification,it is concluded that the accuracy of the forecasting results in 2018.The accuracy of prediction is helpful to the general college students recognize the lack of physical quality,and to direct the practice with sports training theory for school teachers.Divide we make a study and research of each area,then have a handle on the situation of the development of university students' physique health test in Yunnan province.Through two coefficients and two dynamic figures clearly show the Yunnan province ordinary university students' physique test results of individual projects,development status and the development trend of dynamic change.And the coefficient and the dynamic figure show to us that Yunnan province ordinary university college boys' item testing rise than girls' test scores.and there are also rising obesity rates.The level of overall development of lung capacity,50 m,800m and 1000 m has been declining in recent years.From yunnan province ordinary university students' physique health test project in terms of overall development situation of the height and weight of the vital capacity,male female height change is not big,but the girl's weight is big weight than boys with the development of the female lung capacity coefficient and the coefficient of progressive rendering is rising trend,the boy is a little downFrom yunnan province ordinary university students' physique health test project in the 50 m girls 1000 meters 800 meters boys performance coefficient,the development of women 800 m test scores development coefficient is greater than the boys of 1000 meters,are all positive,shows that boys and girls performance overall development presents ascendant trend Boys tend to be in the 50 m running steady rising trendFrom yunnan province ordinary university students' physique health test project in the standing long jump ZuoWeiTi proneness pull-ups the boys and girls 1 minute sit-ups overall trends,in the standing long jump development coefficient of the development of the development of the boys do better than girls,the boy standing long jump improvement is more obvious;In front of the seat body,the female score is superior to that of male students.Boys' pull-ups and girls' one-minute sit-ups tended to decline.Overall trend of the development of yunnan province ordinary university students' physique health is developing forward leveled off,although the individual project present test scores in the test is not very desirable,however,in recent years by sorting out the physical health of test data is towards good direction,the development of social economy,the increase of exercise consciousness,people body nutrition supply is relatively abundant,the improvement of students' body quality training of PE teachers in high education department more and more attention on sports,is the students' physical quality is getting better and better but,compared to the physicalhealth of college students in common colleges and universities in yunnan province coastal urban area and some distanceThe rise and fall of the predicted values does not fully represent the development trend of test scores.It simply reflects the possible value of the test value of the tested object,only as reference data.
