摘　　要：为探讨体育专业大学生指长比及其波动性不对称的特征,进而为体质人类学和优秀运动员身体形态特征的研究积累基础资料,本研究特招募374名18~25岁发育正常的汉族在校大学生为研究对象,按照专业和性别分为男生体育组(n=60)、男生普系组(n=143)、女生体育组(n=61)和女生普系组(n=110),计算各个指长比及两侧指长比的波动不对称值并进行检验。结果显示男生体育组与男生普系组之间的指长比(R)存在统计学差异(P<0.05),差异主要表现在R_(2/5)、R_(3/5)和R_(4/5)上,而女生体育组与女生普系组之间的指长比不存在统计学差异(P>0.05)。结果还显示男生体育组与男生普系组之间的偏差(σ)存在统计学差异(P<0.05),差异主要表现在σ_(2/3)和σ_(2/3)上。而女生的指长比偏差在体育组与普系组之间不存在统计学差异(P>0.05)。通过分析讨论提示出大学生指长比及指长比偏差与性别和运动能力有关,R_(3/5)及σ_(3/5)可能与早期生长发育过程中的性激素的暴露水平有关,而且有望成为运动员选材的新生物标记。To explore the characteristics of the digit ratio(R)and its fluctuating asymmetry for college students majoring in physical education,so as to accumulate basic data for the study of physical anthropology and the physical characteristics of elite athletes,the subjects of this study were Han nationality college students aged 18 years and 25 years old with normal development(n=374).According to their major and sex,they were divided into male sports group(n=60),male general department group(n=143),female sports group(n=61)and female general department group(n=110).Length of the second digit to the fifth digit(L_(2),L_(3),L_(4) and L_(5))was measured by Photoshop 8.0 image processing software,and the fluctuation asymmetrical values of 6 finger length ratios(R)and bilateral finger length ratios were calculated.The normal distribution test,two independent samples T test and Mann-Whitney test of were carried out by SPSS 23.0 statistical software.The result shows there was significant difference in finger length ratios between male sports group and male general department group(P<0.05),which was mainly manifested in R_(2/5),R_(3/5) and R_(4/5),but there was no significant difference in finger length ratios between female sports group and female general department group(P>0.05).The result also shows there was significant difference in the deviation of fluctuation asymmetrical values(σ)between male sports group and male general department group(P<0.05),and the difference was mainly manifested inσ2/3 andσ3/5.There was no significant difference in theσvalue between the female sports group and the female general department group(P>0.05).The study shows that the the digit ratio and itsσare related to sex and sport ability.R_(3/5) andσ_(3/5) may be related to the exposure level of sex hormones during early growth and development,and they are expected to become new biomarkers for athlete selection.
