| On October 20, 2014, the State Council made a < on to accelerate the development of the sports industry promote the sports consumption opinions >,fitness rose to national strategy. "Junior strong, and the country will be strong ", the physical health of young people relationship with our nation's future and the nation prosperous, so for the physical health of adolescents also appears particularly important. National physique study not only improve minority adolescent physical development can promote national unity and safeguarding the unification of the country and with political and economic significance.The transverse 2010 Li Nationality in Hainan, Hainan rural Han and Tibetan 7 to18 years old young male and female students as the research object, Li, Han, Tibetan nationality students physical function as the main research contents and indicators for pairwise comparison, draw the corresponding u, P values and analyze its whether has the difference; vertically in 1985 and 2010 Li Tibetan students in various body function index were compared. Analysis Li Tibetan students' physical function changes, draws the conclusion and puts forward some suggestions.The research methods of this paper include: literature data method, mathematical statistics method, comparative analysis method and expert interview method.The main conclusions are as follows:Spirometry: horizontal, Li Nationality in Hainan, Han and Tibetan adolescents in vital capacity increased with increase of age, the vital capacity of male and female students showed: Han > Li> Tibetan reservoir. Longitudinal, 1985 and 2010 compared to known, Li, Tibetan men and women students vital capacity index in 25 years into a downward trend, decrease in the two peoples are girls more than boys.Pulse: lateral, 2010 Li, Han, Tibetan 7 ~ 18 year old men and women students of pulse index were with the change of age changes, and Li, Han, Tibetan men and women students pulse mean rise and fall. The pulse data show: Li > Han > Tibetan reservoir, then advantages and disadvantages of three national pulse index as follows:Tibetan > Han > Li. Longitudinal, 1985 compared with 2010, Li Nan, the pulse of the girls into decline and the girls decreased amplitude is larger than the male; Li, by contrast, Tibetan 7 to 18 male, the pulse of the adolescent girl students have upward trend, Tibetan boys pulse rise rate is greater than the Tibetan female students.The mean systolic blood pressure of improve the systolic blood pressure of the contraction of the systolic blood pressure systolic blood pressure, systolic blood pressure systolic pressure: horizontal, Han men and women to shrink pressure steady rise, Li and adolescent overall rise, the Tibetan men and women the indexes fluctuate greatly. Longitudinal, 1985 and 2010 compared to know Li 7 to 18 years old girl has declined, but the decline is not obvious; Li 7 ~ 10 years old boy picks up somewhat,11 ~ 18 years old boy pressed into decline trend. Tibetan 7 to 18 years old male,female students into a stage, from 1985 to 2010 in the 25 years, Tibetan 7 to 13 years old girl into a downward trend, from 14 to 18 years old Tibetan girls into a slow upward trend.Diastolic blood pressure: Li, Han, Tibetan men and women students diastolic blood pressure values with age increased, the diastolic pressure data show:Tibetan >Han > Li, then three national youth men and women students diastolic blood pressure merits as follows: Li > Han > Tibetan reservoir. Longitudinal, 1985 and 2010 compared to known, Li, Tibetan men and women students diastolic blood pressure index in 25 years into a downward trend, two national decline are girls more than boys.In view of the above situation, according to the different nationalities of the geographical environment, living habits, policy system, social and economic factors caused by the adolescent physical function caused by the changes, proposed to increase and countermeasures and suggestions to improve the physical function of Li nationality and Tibetan adolescents.Li: strengthen aerobic exercise, reduce the academic burden, to cultivate students' healthy lifestyle, eat less junk food. Tibetan: enhance the awareness of physical exercise, adhere to aerobic exercise, light diet, eat more fruit and vegetables and less meat, drink less. In addition, two areas to improve both inside and outside the school sports facilities, optimization and integration of sports curriculum, open stadiums. |
