2. and 4. Finger Ratio (2D:4D) and Sports

Year 2023, Volume: 2 Issue: 2, 39 - 47, 31.12.2023

Abstract

The length of the second and fourth fingers is closely related to prenatal genital hormones. It has been suggested that low second and fourth finger length ratios (2D:4D) in the fetus are associated with high testosterone and low estrogen levels, and vice versa. This is because there is a genetic basis between the level of exposure to sex steroids during fetal life and the length of these fingers. 2D:4D is one of the important anthropometric measurements to determine physical capacities, as high fetal androgen levels increase the development of cardiovascular systems, good visual-spatial abilities, physical endurance, speed and propensity for agile behaviors that can help in sports.

2. (İşaret) ve 4. (Yüzük) Parmak Oranı (2D:4D) ve Spor

Year 2023, Volume: 2 Issue: 2, 39 - 47, 31.12.2023

Abstract

İkinci ve dördüncü parmakların uzunluklarının doğum öncesi genital hormonlarla yakın ilişkisi vardır. Fetüste ikinci ve dördüncü parmakların uzunluk oranlarının (2D:4D) düşük olması, yüksek testosteron ve düşük östrojen seviyeleri ile ilişkili olduğunu ve bunun tam tersinin de geçerli olduğu ileri sürülmüştür. Bunun sebebi fetal yaşam sırasında seks steroidlerine maruz kalma seviyesi ve bu parmakların uzunluğu arasında genetik bir temel bulunmasından dolayıdır. Yüksek fetal androjen seviyeleri, kardiyovasküler sistemlerin gelişimini, iyi görsel-mekansal yetenekleri, fiziksel dayanıklılığı, hızı ve sporda yardımcı olabilecek atik davranışlara eğilimi arttırdığından 2D:4D, fiziki kapasitelerinin belirlenebilmesi için yapılan önemli antropometrik ölçümlerden biridir.
