摘要
目的:了解高校普通系和体育系大学生身体成分的现状及肥胖发生率。方法:测试在2006-06进行。选择湖北省长江大学二、三年级大学生665人,年龄19～22岁,其中体育学院学生235人(男172人,女63人),普通院系学生430人(男232人,女198人)。所有受试者测试身高、体质量、肱三头肌皮褶厚、肩胛下皮褶厚,计算体脂百分比、瘦体质量、体质量指数,评估肥胖发生情况(男生体脂百分比>18%,女生体脂百分比>25%为肥胖)。结果:665人全部完成测试进入结果分析。①肥胖检出率:普通系男生为5.2%,女生为6.5%;体育系男生为1.4%,女生为3.5%。普通系高于体育系(P<0.01)。②体脂百分比:体育系男生低于普通系男生[(11.46±1.49)%,(13.50±2.44)%,t=-1.73,P<0.01];体育系女生也低于普通系女生[(13.50±2.44)%,(22.69±3.71)%,t=4.77,P<0.01],但普通系学生的均值仍在正常范围内。③除腹部脂肪外,体育系男生身体成分的各指标均优于普通系男生(P<0.01);除肩胛下皮褶厚度外,体育系女生身体成分的各指标均优于普通系女生(P<0.01)。结论:①该校大学生肥胖发生率不高。提示大学生只要坚持一般的身体锻炼就可达到健身防止肥胖的目的,不必追求大运动量。②体育系大学生的体质量和瘦体质量均显著高于普通系大学生。③运动可改变身体局部脂肪的分布,且存在性别差异。
AIM： To understand the present status of body composition in college students from Department of Physical Education and other departments as well as the incidence of obesity.
METHODS： The experiment was conducted in June 2006. 665 sophomores and juniors with the age ranged 19-22 years were selected from Yangtze University of Hubei Province, including 235 students major in physical education （172 males and 63 females） and 430 students of other majors （232 males and 198 females）. All subjects were tested of the body height, body mass, skinfold thickness of musculus triceps branchii, skinfold thickness of subscapularis and their body lipid percentage, lean body mass, body mass index were calculated to evaluate the incidence of obesity （male students with the body fat percentage 〉 18% and female students with the body fat percentage 〉 25% were taken as obesity）.
RESULTS： A total of 665 subjects, who accomplished all tests, were all involved in the analysis of results. （1） Detection rate of obesity： it was 5.2% in male students and was 6.5% in female students of other majors. It was 1.4% in male students major in physical education and was 3.5% in female students major in physical education. The detection rate of obesity was lower in the Department of Physical Education than that in other departments （P 〈 0.01 ）. （2） Body fat percentage： it was lower in male students major in physical education than that in other majors [ （ 11.46±1.49）%, （13.50±2.44）% ,t=-1.73 ,P 〈 0.01], and it was lower in female students major in physical education than that in other majors [（ 13.50±2.44）%, （22.69±3.71）% ,t=4.77 ,P 〈 0.01]. However, the mean of students not major in physical education was still within the normal range. （3）All indexes of body composition except the abdominal fat were better in male students major in physical education than those in male students of other majors （P 〈 0.01 ）. And all indexes of body composition except the skinfold thickness of subscapularis were better in female students major in physical education than those in female students of other majors （P 〈 0.01）.
CONCLUSION： （1） The incidence of obesity in students of Yantze ,University is not high, which indicate that general exercises alone can keep students fit and prevent them from obesity, and it is not necessary to pursue intensive exercise. （2） The body mass and lean body mass in students major in physical education are significantly higher than those in students of other majors. （3） The distribution of local fact can be changed by exercise, while there is difference between different sexes.
