رابطه نسبت طول انگشت دوم به چهارم با قدرت دست برتر و مقادیر هورمون‌های تستوسترون و کورتیزول در والیبالیست‌ها و شناگران پسر

The aim of this study was to investigate the relationship between finger length ratio of the second to fourth with superior hand strength, testosterone and cortisol hormones among volleyball players and swimmers. Studies introduced second to fourth finger ratio (2D: 4D) as a strong and significant predictive factor for talent and athletic ability. This ratio is also associated with testosterone during fetal and adult. Studies have shown that there are negative relationship between 2D: 4D with sports performance, testosterone and positive relationship with cortisol. However, conflicting results have been reported in this area and it must be done more research in this field. Materials and Methods: 60 male athletes in the sports of volleyball and swimming voluntarily participated in this study. Anthropometric measurements, hand size, strength and testosterone and cortisol levels of subjects were evaluated. The Pearson correlation coefficient between variables and T-test to check for assessing of different between groups be used. Results: Although the relationship between 2D: 4D with hand strength, testosterone and testosterone to cortisol ratio was significant in swimming but this relationship was not seen in volleyball (P>0/05). Conclusion: The 2D: 4D was associated with testosterone and strength of swimmers. So the second to fourth finger length may be used in scouting some fields and that more research is needed
