The Influence of the 2D:4D Finger Length Ratio on Swimming Performance
Abstract
This study aimed to investigate the influence of the 2D:4D finger length ratio on swimming performance. A total of 40 swimmers (19 males, 21 females) with a mean age of 12.85 participated in the research, selected from a swimming competition held in Çorum, Turkey. Participants’ anthropometric characteristics, sports experience, and 2D:4D digit ratios were measured. Swimming performance was evaluated using 50 m and 100 m freestyle times. Finger lengths were measured with a digital caliper, and the 2D:4D ratio was calculated by dividing the length of the second finger by that of the fourth finger for each hand. Data were analyzed using independent samples t-tests and Pearson correlation. Results showed no statistically significant differences between genders in terms of height, weight, age, sports experience, finger lengths, or swimming performance (p > 0.05). Furthermore, no significant correlation was found between 2D:4D ratios and swimming performance. These findings suggest that the 2D:4D ratio is not a decisive predictor of performance in swimming, a closed-skill sport. This study contributes to the
