Bu çalışmanın amacı basketbolcularda 2d:4d parmak oranının atış performansına etkisini incelemektir. Çalışmaya 15,04±1,69 yaşında 3 yıldır aktif olarak basketbol oynayan 30 erkek ve 30 kadın basketbolcu katılmıştır. Katılımcıların basketbol şut beceri performansını belirlemek için 0 ile 5 arası puanlayarak serbest atış çizgisinden 5 kez atış yapılması istenmiştir. Parmak uzunluğunu belirlemek için Milimetre (mm) cinsinden 0.01 mm hassasiyetle 0-150 mm (USA, Cocraft) Vernier marka dijital kumpas kullanılarak ikinci parmak (2D) ve dördüncü parmak (4D) katılımcıların her iki elinden ölçüm yapılmıştır. Ayrıca katılımcıların dayanıklılığını ölçmek için 20 Metre Mekik Koşu Testi uygulanmıştır. İstatistiki analiz için Bağımsız örneklem T-Testi ve Pearson korelasyon testi kullanılmıştır. Katılımcıların atış parametrelerinde, Shuttle Run Testte ve diğer 2D ve 4D parametrelerinde anlamlı fark bulunmamıştır (p>0,05). Katılımcıların 20 Metre Mekik Koşu Testi ile sol el 2d:4d değişkenleri arasında ters ilişki vardır (p<0,05). Katılımcıların toplam şut performansı ile 20 Metre Mekik Koşu Testi ve 2d:4d parmak oranı parametrelerinde anlamlı ilişki yoktur (p>0,05). Sonuç olarak adölesan erkek ve kız basketbolcularda 2D: 4D ile aerobik performans ve şut arasında bir etkinin olmadığı bulunmuştur. Bu sonuç örneklem grubunun yaşından, antrenman seviyesinden ve heterojenliğinden kaynaklanabilir.

The 2nd:4th digit ratio and shooting skill performance in Basketball Players

Abstract

The aim of this study was to investigate the effect of 2d:4d digit ratio on shooting performance in basketball players. 30 male and 30 female basketball players who have been actively playing basketball for 3 years at the age of 15±04.1.69 participated in the study. Participants were asked to score 5 shots from the free throw line by scoring between 0 and 5 to determine their basketball shooting skill performance. To determine finger length, the second finger (2D) and fourth finger (4D) (Figure 3) were measured using a 0-150 mm (USA, Cocraft) Vernier digital caliper with an accuracy of 0.01 mm in millimeters (mm). In addition, the 20 Meter Shuttle Running Test was applied to measure the endurance of the participants. Independent sample T-Test and Pearson correlation test were used for statistical analysis. There was no significant difference in the participants' shot parameters, Shuttle Run Test and other 2D and 4D parameters (p>0.05). There was a negative correlation between the 20 Meter Shuttle Running Test and the left hand 2d:4d variables of the participants (p<0.05). There was no significant relationship between the total shot performance of the participants and the parameters of the 20 Meter Shuttle Running Test and 2d:4d digit ratio (p>0.05). It was found that there was no effect between 2D: 4D and aerobic performance and shooting in adolescent male and female basketball players. This result may be due to the age, training level and heterogeneity of the sample group.
