Abstract
Introduction: Fencing is a sport of skill, speed and power. Since testosterone have a significant role in the development of muscle mass and affect neural and muscular performance, can be important role to success in fencing. Many studies have reported that digit ratio (2D:4D) as a powerful indicator for athletic talent. It is believe that the 2D:4D negatively correlates with prenatal testosterone and positively with prenatal estrogen. However, there were no significant correlation between circulatory testosterone and 2D:4D. Sports provide a physical challenge and participants often show increased levels of free testosterone immediately preceding and during competition. We tested this hypothesis of link between digit ratio (2D:4D) with salivary testosterone, salivary cortisol and testosterone to cortisol ratio after physical challenge in Iranian national team males of fencing.
Methodology: For this purpose, 10 male of Iranian national team fencing with a mean age of 26.4±3.83, selected purposefully. The finger parameters were evaluate using the digital caliper. Also saliva samples were assayed for hormones before warm-up and 15 minutes after a competition. Statistical analysis conducted using Pearson correlation, and the level of significance was considered as P≤0.05.
Results: The statistical analysis showed that digit ratio was not significantly correlate with salivary testosterone, salivary cortisol and testosterone to cortisol ratio after physical challenge in the present study P≥0.05.
Discussion: Findings suggest that this index can not be used to identify and discover talented in fencing. Therefore, in order to make operational use of these results and accurate conclusions, further research is needed in this field.
