The Research Of Five Minorities’s Children’s Physical Quality Change Of Characteristics And Trend

Research purposes:By 5 minorities (Uygur, Korean, Hui, Tibetan, Zhuang) children and adolescents aged 7-17 nationwide survey data in physical fitness related indicators from 1995 to 2010 were analyzed and comparison, by means of these gray prediction 5 minorities children and adolescents in the next 10 years to predict the physical analysis, to explore and discuss these five categories reveal the growth trend of minority children and adolescents, provide a reference for further research and intervention work in the future.Research methods:this thesis has adopted documentary analysis method, mathematical statistics and data analysis. Previously established by the country physical indicators related data from 1995,2000,2005and 2010 four Chinese students’physique and health research report. Select from 7-17 years old physique monitoring indicators of Uygur, Korean, Hui, Tibetan and Zhuang. Including speed quality (50m), endurance quality (50*8 shuttle run,800m women,1000m men), muscle strength (crunches female, pull-up/pull-up Xieshen male), flexibility (sit and reach),lung capacity. Han students in the city and 1990,1995,2000,2005,2010 50m race data for statistical analysis and gray prediction. Research results:1、(during 1995-2010) speed qualities:speed quality girls than boys more pronounced downward trend. Tibetan boys 50m average increase of 0.05 seconds, speed, quality of 15 years remaining 4 class minority showed a downward trend, which is the most significant decline in the Korean girl, a decline of 0.77 seconds.2、endurance qualities:5 class minority endurance quality showed a downward trend,and endurance quality girls than boys more pronounced downward trend, which is the most significant decline in Muslim girls,800m run decline of 27.46 seconds.3、muscle strength qualities:Tibetan boys and girls in muscle strength is rising,the average increase was 2.35 male/0.82 (pcs/min); girls an average of 0.59 (pcs/min), and the remaining four categories minority are declining.4、Flexibility:Flexibility girls than boys outstanding, and only Muslim boys and girls flexibility is rising, the increases are:boys,1.11cm; girls,2.43cm.5、FVC:Only Tibetan men, girls and boys Korean spiroetry in 15 years on the rise, they increase are: Tibetan boys,194.08ml; Tibetan girls 453.57ml, Korean boys 1.35ml. The most significant decline was Uighur boys, a decline of 501.27ml.6、 to predict the next 10 years:a downward trend over the next 10 years to predict the results of the previous 15 years, more obvious. In the five indicators of physical fitness, physical fitness shown by projections showing a majority of indicators showing trend is 2020<2015 <(1995-2010).But there are some minority physical quality index showed a trend of rising, such as:the quality of the hui nationality girls muscle strength, flexibility, respectively in 2015 and 2015, the rising trend, the speed quality in 7-11 appeared rising trend.Research Conclusions:Overall, the five minority class endurance qualities are not optimistic.Tibetan Children slightly better than the other four categories minorities. The Speed, endurance, muscle strength, flexibility, lung capacity of 5 minorities 7-17 years old students in recent 15 years especially in the recent 5 years fell obviously. Through the DGM (1.1) model for the development of 2015 and 2020, according to the prediction of most of the physical quality index decreasing trends, but there are also part of the nation is on the rise.
