Abstract:

Objective To study the basic situation of vital capacity and body composition of the multi ethnicity college students in Guangxi, and to explore the correlation between vital capacity and body composition. Methods The vital capacity and body composition of 1322 students who volunteered to participate in the investigation in a college in Guangxi were measured, and carried on the statistical analysis. Results There were ethnic differences in vital capacity, muscle volume, estimated bonse mass, body moisture and protein among the Han, Zhuang and other ethnic minority students (P<0.05). In the correlation analysis, the vital capacity and the amount of fat were negatively correlated (correlation coefficient r=-0.092, P<0.01). The vital capacity and muscle mass, the presumption of bone mass, body moisture and protein content were positively correlated (correlation coefficients were 0.687,0.633,0.658,0.653,respectively and P<0.01).Conclusion Ethnic differences are in vital capacity and some body composition among ethnic university students in Guangxi, and the comparison of the vital capacity and body composition among the three are: Han＞Other minorities＞Zhuang. The higher lung capacity, the lower the amount of fat in the body, and the higher muscle mass, bone mass, body moisture and protein content.
