다국어 초록 (Multilingual Abstract)

The purpose of this study was to reveal the relationship between 2D:4D digit ratio and physique, physical fitness of 2nd~5th grade elementary school students who applied the selection test for sports talented children program. 441 students took X-ray pictures for 2D:4D digit ratio and participated the several tests including body measurement, basal physical fitness test, sports relevance ratio and GXT for V˙ O2max For the comparison, all of participants were divided into three groups according 2D:4D digit ratio(high: over 75%, middle: 25~75%, low: below 25%), and then all results such as physique, fitness and V˙ O2max were compared among groups. Results were followed as below: The first, 2D:4D between boy and girl were no significant difference, but there were tendency that boy’s 2D:4D were lower than girl’s. The second, while difference in sitting height, weight, chest circumference, %fat, BMI of 4th grade boy, boy’s %fat of 2nd grade and sitting height of 5th grade boy were different according 2D:4D digit ratio. The third, there were no significant difference in all physique of girl. The fourth, on the comparison of fitness according 2D:4D digit ratio, sit-up, half-squat jump, standing long jump, sit & reach record of 4th grade boy were different significantly. On the other hand, any basal fitness record of all of grade girl was not different significantly according 2D:4D digit ratio, even any tendency was not shown. The fifth, boy’s sports relevance ratio of 2nd and 4th grade were different according 2D:4D digit ratio, but not in girl’s sports relevance ratio. The sixth, while high group of digit ratio in girl showed higher V˙ O2max than low group, boy’s V˙ O2max had the tendency of negative correlation with 2D:4D digit ratio. However, we didn’t find any consistent distinct feature of 2D:4D ratio suggested by other research works. Therefore, we concluded that 2D:4D digit ratio might have not enough influence to predict physique and fitness ability.
