| Abstract |
PURPOSE
The purpose of this study was to examine the utility of 2D:4D(second digit to fourth digit ratio) as the subsidiary measure for expecting physical fitness when it comes to the recruiting student athletes.
METHOD
In order to achieve the goal of this study, the researcher visited 5 schools to measure 2D:4D of students. Sixty non-athletic students and 32 athletic club students were participated in this study. They were in 3rd and 4th grade from B, K, I, N and S elementary school located in Seoul D district. Software-based measurement was used to conduct this study which was strongly suggested to the highest precision estimates by Kemper & Schwerdtfeger(2009). Therefore electronic images of hands were used for analysis. Measurement were made with Adobe Photoshop with pixel accuracy. The t test was used to compare of putative marker of prenatal androgen exposure between athletic club and non-athletic students in the elementary school.
RESULT
There were significant differences between 2D:4D of athletic club students and 2D:4D of non-athletic students.
First, 2D:4D of athletic club students showed the lower value than 2D:4D of non-athletic students(p<.01). Second, 2D:4D of baseball club students showed the lower value than 2D:4D of non-athletic students(p<.05). Third, 2D:4D of soccer club students showed the lower value than 2D:4D of non-athletic students(p<.05).
CONCLUSION
Based on the results of this study, 2D:4D can be considered when the schools recruit athletes. However, physical fitness is not decided by only innate factors. Thus this paper suggest that Blind faith in 2D:4D should be avoided. |
