相同BMI独生与非独生子女大学男生身体素质差异 　　摘要:对山西省3 406名BMI处在同一等级男大学生身体素质等指标进行分析。结果显示:大学男生BMI等级分布总体处于良好状态,体型正常的比例在75%左右;相同BMI等级独生与非独生男大学生身体素质间存在着一定的差异,主要表现为:独生男生在短距离、短时间、高强度快速爆发力项目略强于非独生男生,而在长距离的耐力跑等方面却明显落后于非独生男生,5项素质总体得分独生男生明显低于非独生男生;大学男生身体成分中,去脂体重与体脂率的不同是引起身体素质间差异的主要内在因素,即体脂率与脂肪含量成正比,与去脂体重及人体运动能力成反比;运动因素是引起独生与非独生男大学生身体素质差异的客观因素之一。 　　关键词:体重指数;身体素质;大学男生 　　中图分类号:G804.49 文献标识码:A文章编号:1006-7116(2009)10-0065-05 　　 　　Differences in constitution between male college students in Single-child and Non-single-child with the same BMI 　　LIU Yao 　　(School of Physical Education,Shanxi University,Taiyuan 030006,China) 　　 　　Abstract: By means of literature data research and physical component analysis, the author performed a comprehensive analysis on multiple indexes such as constitution with respect to 3,406 male college students with a BMI at the same level, and revealed the following findings: the distribution of BMI of male college students is generally in a good condition, the percentage of the students with a normal figure is 75% or so; there are certain differences in constitution between singleton and non singleton male college students with a BMI at the same level, which mainly show in the followings: in quick power explosion required short distance, short time and high intensity events, singleton male students performed slightly better than non singleton male students, yet in stamina required long distance runs, singleton male students performed significantly poorer than non singleton male students; the overall score for 5 constitutional indexes for singleton male students is significantly lower than the same for non singleton male students; in the physical components of male college students, the differences in the degreased body weight and the body fat ratio are the major intrinsic factors that cause the differences in constitution, i.e. the body fat ratio is proportional to the fat content, and inversely proportional to the degreased body mass and the sports capacity of the hu
