摘要:
探究广西在校大学生的身体脂肪参数对肺功能的影响,为改善大学生身体功能素质提供依据.方法 随机抽取广西医科大学2 462名(男生716名,女生1 746名)在校大学生为研究对象,并采用奥美体成分测量仪(Tanita MC-180)测量身体脂肪参数,参照国家体质健康测试标准统一测试大学生的身高、体重及肺活量.采用SPSS 20.0软件对数据进行分析.结果 男女大学生的肺活量均随着体脂率的增加呈上升趋势,肺活量体重指数均随着体脂率的增加呈下降趋势(F值分别为41.627,69.196,P值均<0.05).体脂率过低组男大学生肺活量体重指数与身体各部位脂肪参数的相关均无统计学意义(P值均>0.05),体脂率过高组和标准组的肺活量体重指数与不同部位的脂肪参数呈不同程度的负相关性(r值均<0,P值均<0.05).在女大学生中,仅有体脂率过低组和标准组的肺活量体重指数与身体各部位脂肪参数呈负相关(r值均<0,P值均<0.05),体脂率过高组的肺活量体重指数与身体各部位脂肪参数的相关均无统计学意义(P值均>0.05).结论 大学生部分身体脂肪参数可导致一定程度的肺活量体重指数下降,对大学生的肺功能造成一定影响.保持身体各部位适宜的脂肪含量对改善大学生的身体健康和肺功能有一定积极作用.

Abstract:
Objective To explore the effects of body fat measurement on vital capacity among college students in Guangxi.Methods A total of 2 462 college students (716 male) were randomly selected in Guangxi.Body fat indices were measured by Tanita MC-180.Height,weight and vital capacity were examined according to the national physical fitness test standard.Data were analyzed by SPSS20.0 software.Results The vital capacity of male and female college students increased,while the vital capacity/ weight index decreased with body fat percentage.Negative associations were found between vital capacity/weight index with body fat percentage among male students with moderate and high body fat percentage,except males with low body fat.Among female students with low and moderate body fat percentage,the vital capacity/weight index was negatively correlated with fat parameters at different positions,no such association were found in high body fat group.Conclusion Excessive body fat correlates with low vital capacity among college students.Body fat plays an important role for proper lung function.
