“…Manning (2002) and Lutchmaya et al (2004) found that the male athletes 2D:4D ratio in both hands was lower than female athletes in their studies. Lu et al (2017), found similar results in the study (n=346), and all of these results, which were lower for men's 2D:4D average than women (Manning et al, 1998;Manning and Taylor 2001;Hönekopp & Watson, 2011;Van Honka et al 2011) confirm the literature information. In our findings, the 2D:4D averages are lower than the 2D:4D averages in both men and girls.…”

The index finger and the 4th finger ratio (2D:4D) is the indicator of the prenatal testosterone. The aim of this study is to investigate the relationship between 2D:4D, hand preference and hand grip strength in swimmers. A total of 80 elite swimmers, participated in the study. Height, body weight, body mass index (BMI), hand 2D:4D finger measurements and hand grip strength tests were performed for athletes. The hand preference was determined by the Oldfield questionnaire and it was evaluated according to the Geschwind score. The data were recorded in the SPSS 20 program and p<0.05 was considered as statistically significant. It was found that in both men and women, a negative correlation was found between right and left hand 2D:4D and both dominant (DHGS) and non-dominant hand grip strength (NDHGS) values. It was found that men had lower 2D:4D ratio than women. For both right and left handed, there was a statistically significant difference between the right and left hand 2D:4D ratios in both men and women (p<0.05) and the dominant hand (DH) 2D:4D ratios were found to be lower than non-dominant hand (NDH) 2D:4D ratios in both men and women (p<0.05) It can be said that the 2D:4D ratios may be the effect of determining the hand preference, the grip strength and therefore the strength.

“…Lu et al, (2017), determined negative significant differences between 2D:4D and hand grip strengths in his study (n=346). The results are similar and support the literature knowledge (Hönekopp & Shuster, 2010) that the 2D:4D ratio is negatively associated with force, physical strength and athletic performance.…”

Background: The ratio of the lengths of the index and the ring finger (2D:4D ratio) is generally different between men and women. This has often been used as an indicator of the levels of prenatal androgen exposure. It has hence been suggested to have a role in many gender differences including performance in sports. Men generally outperform women in most physical abilities. However, reports in various studies have been inconclusive, depending upon the physical ability tested. Hand Grip Strength (HGS) is a good measure of overall strength of an individual. Hence, we decided to determine the relationship between 2D:4D and HGS of both hands in men and women.Methods: Scanned images of both hands of young volunteers were analysed and the 2D:4D ratio calculated. HGS was measured and results correlated with 2D:4D.Results: 2D:4D ratio of men was significantly less than of women for the right (p<0.001) and the left hand (p<0.001). HGS of men was significantly greater than that of women for the right (p<0.0001) and for the left hand (p<0.0001). 2D:4D ratio in men showed a weak but significant positive correlation with HGS of right(p<0.05) and left hand(p<0.05). A weak but significant positive correlation was also seen for the left hand in females. However, 2D:4D ratios did not show any significant correlation with HGS for the right hand in women.Conclusions: We conclude that 2D:4D ratio is a measure of Hand Grip Strength in men, but is not a robust measure of HGS in women.

“…The lower the ratio, the better the test results. Such direction of the correlations was also observed by H. Lu et al (2017). The tests cover strength and time-trial, where a high muscle content is significant (a feature not characteristic for women).…”

The aim of the paper was to evaluate the digit ratio between groups of sporting and non-sporting women and men, and attempt to determine a value typical for athletes of each gender. Additionally, the aim was to evaluate relations of the digit ratio with both the somatic structure and motor fitness, which could then be used to improve on sports selection criteria. The research material comprised 22 anthropometric measurements together with results of four motor fitness tests of students active in various sports disciplines. The control group comprised students who had never practiced sport. The sporting students showed significantly lower digit ratios compared to the control group of non-sporting students. Correlations between the digit ratio and features of the body structure were low. Both sexes recorded significant negative correlations between the digit ratio and handgrip strength, as well as with the long jump length. Those with a lower value of the digit ratio had better predispositions to practicing sports.
