ABSTRACT
Objective To study the physical characteristics of body of Xibe adults in Liaoning province and to accumulate data for the studyof physical anthropology. Methods The investigation method and judging standard were refered to correlative regulations in " Anthropometric Method ". The survey included 33 measurement items, 5 indicators and 6 types, 330 Xibe adult people (male 174, female 156) were recruited. Results According to the classification of body part index, the rates of long trunk, wide chest, wide shoulder and wide pelvis were the highest in all the adults of Xibe nationality in Liaoning province, the rates of middle and sub-long legs were the highest in the males, and the rates of super short legs were the highest in the females. According to the stature type, the rates of high type were the highest in males and females. Conclusion The body physical characteristics of male adults of Xibe nationality in Liaoning are the most similar to those of male adults of Xibe nationality in Xinjiang, and the body physical characteristics of female adults of Xibe nationality in Liaoning were between those of female adults of ethnic minorities in Northwest China and Northeast China.
ABSTRACT
Objective To explore the characteristics and differences of the distribution of skeletal muscle content between the Han adult population in Tibet and Liaoning Han adult population. Methods Randomly selected healthy adults of Han worked in Tibet and Liaoning Han nationality as the research object, a total of 223 Han adults worked in Tibet ( 95 males, 128 females); 302 adults of Han nationality in Liaoning (126 males, 176 females) were selected by body composition analyzer. The body weight, total muscle mass, trunk muscle mass, left upper limb muscle mass, right upper limb muscle mass, left lower limb muscle mass, and right lower limb muscle mass of the subject were measured. All the result were input into SPSS 22. 0 statistical analysis, and related statistical processing such as independent sample t test was applied. Results The body weight, trunk muscle mass, left upper limb muscle mass, right upper limb muscle mass, left lower limb muscle mass, and lower right muscle mass of the Tibetan Han population were lower than those of the Han adults in Liaoning, and the comparison result was significantly different (P<0.01 or P<0.05), the Han adults in Liaoning and the Tibetan Han population, male muscle mass was greater than the female adults (P<0.01 or P<0.05). Conclusion After the Han people in Liaoning entered the Tibetan Plateau, the muscle mass of each part of the body decrease significantly. The change of human body composition can be affected by various factors such as gender and high altitude hypoxia environment.
