【摘要】 目的了解广西多民族大学生肺活量和体成分的基本情况,并探讨两者的相关性。方法对自愿参加调查的广西某高校1322名学生进行肺活量及体成分测定,并进行统计学分析。结果汉族、壮族及其他少数民族大学生的肺活量、肌肉量、推定骨量、身体水分及蛋白质均存在民族差异(P<0.05);相关分析中,肺活量与脂肪量成负相关关系(相关系数r=-0.092,P<0.01);肺活量与肌肉量、推定骨量、身体水分及蛋白质含量成正相关关系(相关系数分别为0.687、0.633、0.658及0.653,均P<0.01)。结论广西多民族大学生的肺活量及部分体成分存在民族差异,三者中肺活量及部分体成分的比较:汉族>其他少数民族>壮族;增加肺活量,则体内脂肪量越低,肌肉量、推定骨量、身体水分及蛋白质含量越高。更多还原

【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.更多还原
