摘要
以174例(男103例,女71例) 18~60周岁的河南汉族成年人为研究对象,按照性别和专业分组,分别测量食指(2D)、中指(3D)、无名指(4D)和小指(5D)长度并计算相应的指长比.采用SPSS 23.0进行数据处理,组间比较采用t检验和多因素方差分析.结果显示:(1)性别组中,除2D∶3D和R2D∶4D外,其他指长比在组间差异有统计学意义(P<0.05),其中3D∶5D差异最显著;(2)专业组中,除2D∶3D和R2D∶4D外,其他指长比在体育专业和非体育专业组间差异有统计学意义(P<0.05),其中3D∶5D差异最显著;(3)在性别组和专业组中,指长比的侧别差异均无统计学意义(P> 0.05).指长比在性别组和专业组中差异显著,其中3D∶5D的差异是最显著的,推测5D相关的指长比与性别和运动能力关系密切.
The 174 adults( 103 males,71 females) of Han ethnic aged 18 to 60 yeas were studied and they were grouped by gender and major respectively. The length of index finger( 2 D),middle finger( 3 D),ring finger( 4 D)and little finger( 5 D) were measured and the corresponding digit ratio was calculated. SPSS 23.0 was used for data analysis.The t test and multi-way ANOVA were used to compare the group differences.The results showed:( 1) When grouped by gender,there were significant differences between men and women in all digit ratios except 2 D ∶ 3 D and R2 D ∶ 4 D( P<0.05). The sex difference in 3 D ∶ 5 D was the most significant.( 2) When grouped by major,there were significant differences between PE major and non-PE major in all digit ratios except 2 D ∶ 3 D and R2 D ∶ 4 D( P < 0.05). The difference in 3 D ∶ 5 D was the most significant.( 3) There were no statistically significant differences in all digit ratios between left and right hands( P>0.05). It is speculated that the 5 D related digit ratios were closely related to the sex and athletic ability.
