Abstract

Several studies have shown the importance of anthropometric measurements as a veritable tool in forensic science, crime detection, as well as a means of studying variations in human populations. The present study focused on using digit lengths and ratio to determine sports skills. A total of 270 female subjects comprising of sports and non-sports participants were measured. Seventy of which were non-footballer athletes, 100 were footballer athletes, and 100 were non sports participants. The second and fourth digits of their right and left hands were measured using a digital vernier caliper. The data obtained from the participants were analyzed by SPSS. Subjects who participated in football also possessed athletic skills, hence both have similar traits. This study has shown that athletic and football skills are similar, as the values obtained from the above parameters were not significant at p<0.05. The results showed that digit ratio is not a good tool for determining sport skills, as compared to digit lengths (2D and 4D). No difference was observed between the digit ratio of the sports participants and those of non-sports participants. Digit lengths (2D and 4D) were found to be significant determinants of sports, with sports groups showing significantly shorter digits. Therefore, the findings of this study suggest an association between digit lengths and sporting abilities.
