摘要
为了解大学生体成分现状,采用身高计、皮尺、体成分仪对1 270名大学生进行测试.研究显示:男生体脂肪率、内脏脂肪指数随年龄增大呈先增长,而后下降,随后再增长的发展趋势;女生体脂肪率、内脏脂肪指数随年龄增大呈现增长,而后下降,随后再增长,再下降的发展样态.男生肌肉率随年龄增大呈先增长而后趋于稳定的趋势;女生的肌肉率18-21岁相对比较稳定,而后随年龄增大呈而增长趋势.男女生的骨量、水分量均随年龄增大而增长,男女生同年龄段体成分各指标比较均有显著性(P<0.01),体脂肪量、体脂肪率男生低于女生,其余各指标高于女生.男、女生的体重、腰围与体脂肪率、内脏脂肪指数、骨量、水分量均呈显著正相关,与肌肉率呈显著负相关.结果表明:男女生各年龄段体成分各指标的平均水平均在正常范围,女生体成分各指标随年龄增长的发展趋势好于男生.男生的主要问题是随年龄增长内脏脂肪迅速增大,这对健康是极为不利的.
A survey is made among 1 270 college students to collect information about their status of body composition. Results show that the body fat,visceral fat index of male students present a trend of increase,decrease,increase again along with the age;females present increase,decrease,increase,then decrease. The muscle ratio of male students increases at first,and then tends to be stable with the age;muscle ratio of females aged 18-21 is relatively stable,and increases with the increase age. Bone mass and water quantity of male and female students both increase along with the age. The body composition index of same age is of significant difference （P〈0.01）,in which body fat mass and body fat percentage of males are lower than females. The body weight,waist circumference are positively related to body fat percentage,visceral fat index,bone volume,water volume,and negatively correlated with muscle ratio. Conclusion can be drawn that the average level of each index of body composition in different ages is in the normal range,and the trend of index of body composition in females is better than males. The main problem of males is that visceral fat increases rapidly with the growth of the age,and it is extremely detrimental to health.
