Hainan Li Nationality Middle School Students’ Physical Anthropology Research

Physical anthropology is based on the human body as a whole or local measurement and observation, individual measure system development and the physical changes that take place in the process of growth, can also be used to evaluate individual nutrition, fat, physical status and an important index of body size, etc.So far, Chinese scholars have in 43 ethnic minorities in the country measurement and observational studies have been carried out physical features,in addition, Anthropometry technology has been widely applied in child and adolescent growth and development of all ethnic groups in the research, physical assessment of students study, sports, etc, etc., but for the minority students of physical anthropology research data is less, for hainan li nationality middle school students’ physical anthropology research has not been reported.This article adopts the method of human body measurement and observation, select a representative sample of the hainan li nationality settlements, the 657 high school students(including 302 male students, female students, 355), height, weight, head of facial morphology, skinfold and body surround degree of 24 indexes in three aspects: the measurement and observation, and then according to the measured numerical calculate li middle school students’ body mass index(BMI, head width, morphological facial index, 4indicators, such as nasal index on this basis, combining with the literature material law,comparative statistics, mathematical statistics, etc., study of hainan li nationality middle school students’ physical anthropology, the results are as follows:1. Li the height of middle school students aged from 13 to 18 increased with age, high school students and rural middle school students average height slightly higher than the city, but urban middle school students average weight measuring is higher than rural middle school students, aged 14 to 16 age between height and weight are the largest growth. Li middle school students’ height and weight are exist significant differences between sex, age. But there was no significant difference in urban and rural areas.2.Through comparing found that height, weight, BMI, li male students belong to medium,medium height, school students belong to medium, medium height; Its weight are underweight; Body mass index value are below standard, namely the hainan li male and female students all belong to "light".3. Li 77% with upper eyelid fold for middle school students, mainly partial black hair(40.2%),there are round the earlobe Numbers(88.1%) and chin(85.4%), mainly straight arms extend mainly straight stretch type(63.3%), legs are mainly with straight legs(61.6%).4.Li head facial measurements of every index for middle school students, rural students of measuring average higher than the city students, and the measured value of the boys than girls.In addition, head length measured value, high morphological facial measurements exist significant differences in age, wide measured value, the nose and nasal index in age differences statistically significant, morphological facial index, there exist some differences in gender, nose breadth difference exists in the urban and rural areas. Li male students head type in the majority with round head type, li school students head type is mainly for the head type.5.Skinfold measurements in the main part of body, from high to low in turn is: leg medial skinfold, Jia crease, iliac acanthosis plait, cheek skinfold thickness, triceps skinfold. Skinfold measurement value of each part of the city students were higher than rural students, measured values higher than the girls and boys measured values. The triceps skinfold, iliac spine on skinfold, there exist some differences in gender, age, crus inside skinfold in urban and rural differences.6.Body is surrounded degree of measured values that increases along with the growth of the age, the calm chest measurement value maximum, minimum value upper arm circumference measurement. And calm the chest, legs around there are significant differences in sex and age,waist circumference differences on gender and urban and rural areas.According to the situation of li characteristics of physical anthropology, put forward th following Suggestions:1.Parents should strengthen nutrition supplement for middle school students, reasonable diet to improve high school students2. High school itself should often take part in physical exercise, promote the healthy growth of the body3. The physical education teachers should enrich sports curriculum, introducing li sports in the classroom4. The competent department of education should attach importance to li school sports, seize the campus football upgrade opportunities...
