Comparative Research On Physical Condition Of (7 To 18 Years Old) Ordinary And Obese Students In University Of Technology Affiliated School

As the backbone of the nation's future construction, Teenage's physical health directly leads to the whole nation's rise and fall. With the rapidly development of economic, people's living standard rise ceaselessly. The youth obesity trends is heightened constantly, also, teenage's obesity is becoming one of the important issue in global public health problems. People concerned more about teenage's obese degree. Simple obesity is the killer which threatened children's healthy. It is not only affects teenage's mental and physical development, but also is the risk factors for various diseases when they grow up. Therefore, the study of youth obesity is good for the children's healthy growth, and is more advantageous to the country's rapid development.This paper takes Tai Yuan university of technology affiliated primary and middle school students (7-18) Obese Students and ordinary life for the study, using physical tests, mathematical statistics, the methods of documentation and comparative analysis. It discusses the present situation of constitution teenage children obesity and their change rule. Through these research, it aimed at reducing teenage's obesity happens, and improve their obese status provide valuable reference. The research and conclusion about this paper are list as follows:(1) Obesity:Tai Yuan university of technology in 2010 affiliated primary and middle school students (7 to 18 years old), including medical obesity rate 8.69% 7.27% 10.01%, girls, boys than girls, men and women boys obesity in 7-eclipsing all appear 12 years of age 13 to 18 years of age than the situation.(2) Body Shape:Tai Yuan University of Technology affiliated primary and middle school students (7 to 18 years old) with age, height, and the increase of taller. Two groups of higher amplitude basic same, but they in the growth peak: boys aged 13-15, girls in 10 to 12 years of age. Weight and BMI also increase with age group in improved, but are much higher than the control group; Weight is team boys aged 13-15, girls 10-12 years of age, their growth rate higher than other age groups. Research group of BMI is largest increase in the 13 to 15 years of age.(3) The body function:Tai Yuan University of Technology affiliated primary and middle school students (7 to 18 years old), vital capacity and vital capacity/BMI increased with age in improving, but vital capacity index more than control group the phenomenon, deserves further investigation. Vital capacity/body mass index, the team obviously lower than those of the control one, the team body function ability is poor.(4) The body quality respect:Tai Yuan University of Technology affiliated primary and middle school students (7 to 18 years old) physical quality indexes in improving the increase with age group 50 meters (women than 16-18 13-15 years old and male and female ZuoWeiTi proneness 10-12 years old than 7-9 years old except), the physical qualities of the research group are poorer than the control ones.50 meters run:gender differences before 12 years old is not big, but 13 years old; increase significantly after gap. And the male, the girls all appear to increase with age increase amplitude decreases.Standing long jump:male, the girl group all appear age minor differences small, age large gap big trend; Standing long jump results of the amplitude, each age growth 15-year-old boys 13-reached a peak, while girls are as he grew older increase gradually decrease.Zuo Weiti proneness:the girl was significantly better than boys; The growing. Rate of all ages, male, girls are in the 13-15 years old, and reached its peak both male and female teams than the control group increase was big.Endurance events:7 to 12 years of age 50 meters 6x8 run, seven and nine years of age in boys and girls good, but 10-12 years of age is better than girls.
