Abstract

Object: explore the differences of physique characteristics between Dai college students in Xishuangbanna tropic zone and Li college students in Five Finger Mountain tropic zone, which may provide theoretical reference for improvement of physical fitness of different ethnic college students. Method: physical fitness index was tested on the basis of the latest revision of national student physical health standard in 2014, and physical fitness test data were analyzed by SPSS 16.0 software. Results: there are no significant differences of physical characteristics and nutritional condition between Li and Dai college students (P ＞ 0.05), and no significant differences of speed quality and lumbar abdomen power (P ＞ 0.05), but the cardiopulmonary level and endurance quality of Li college students are higher than Dai college students (male: P<0.01; female: P<0.05). Conclusion: two tropic zones have similar geographical environment, social economic production and dietary habits, so there are no significant differences of physical characteristics and nutritional condition of body between Li and Dai college students. Compared with Li college students, Dai college students live and study in high altitude area which affected by low supply of oxygen, and this may cause the oxygen uptake and cardiopulmonary function level of Li college students are higher than Dai college students. Bamboo dancing of Li nationality runs through the whole process of teaching, so male Li college students’ long-term training of beating bamboo posts with sticks lead to great upper body strength, and the bamboo dancing also lead to good flexibility and jumping ability of Li college students.
