Comparative Study on the Characteristics of College Students’ Physical Fitness between Li and Dai College Students in Two Tropic Zones

Abstract

Objectives : 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. Methods : The research is consulted college Students' physical study of modern literature, and citing references for evidence and discussion through CNKI, Chinese Journal Fulltext Database, and guidance document of the Chinese government on students' physical health and nutrition. Physical fitness test using State Sports General Administration of intelligent recommendation (automatic test), and “revised national students health standard (2014)”. Method of experiment and mathematical statistics- SPSS17.0 software is used for T test, and statistical results were expressed by x ± S, no significant difference was expressed by P > 0.05, significant difference, P < 0.05, extremely significant difference, P < 0.01. Results : Comparison of morphological and functional indexes between Dai and Li students, T test showed that there was no significant difference in body shape (height and weight) between Li and Dai college students ( P > 0.05), but the body function (vital capacity) index of Li college students is significant higher than Dai college students(male P < 0.01; female P < 0.05). Comparison of morphological and functional derived indexes between Dai and Li students, T test showed that there were no significant differences of weight (kg)/height (CM) ∗ 1000 between Dai and Li college students ( P > 0.05). And the body function, ital capacity (mL)/weight (kg) index of Li college students is significantly higher than Dai college students (male P < 0.01, female P < 0.05). It shows that compare with Dai college students, the physical function of allocation of oxygen and cardiorespiratory function of Li college students are relatively higher. Comparison of physical fitness indicators between Dai and Li students, The statistics show that except 50 m, the score of chin up, sit and reach, long jump, 1000 m of Li male college students are significantly better Dai male college students ( P < 0.01 or P < 0.05). It means the physical quality of Dai male college students is relatively better than Li college students. On the other hand, there were no significant differences of 50 m and sit ups among Dai and Li female college students ( P > 0.05). And the score of sit and reach, long jump and 800 m of Li female college students are significantly better than Dai college students ( P < 0.01 or P < 0.05). It means that the physical flexibility, jumping agility and running endurance of Li female college students are relatively better than Dai female college students. Conclusions : Dai and Li college students have the same background of physical education and nutrition, and both have similar climate and environment of the birth place which are Xishuangbanna and Five Fingers Xishuangbanna tropical rain forest area, the economic production activities and the diet custom are also similar, so body shape test indexes and relative derivative indexes of Dai and Li college students had no significant differences, no significant differences in body movement, speed, strength, and waist strength. However, the Dai and Li students still show significant differences in physical function and physical fitness indicators.
