Özet:

 Early identification and development of talented athletes in youth sport is of primary interest to national governing bodies of sport and sport clubs across all sports. Selection bias during recruitment and planning the developmental pathways of athletes is a critical issue to address, and relative age effect RAE is one of the concepts to be investigated in this regard. The aim of this study was to examine the prevalence of RAE in U17 and U20 FIFA Womens World Cup, and to investigate the role of age category, playing position and continents with regard to RAE. A total of 2016 female soccer players U171008, U201008 participating in the last three consecutive U17 and U20 FIFA Womens World Cups were evaluated based on the birth month distributions. Inter-quartile differences were assessed using the Chi-square χ² goodness-of-fit test, and odds ratios OR and 95 confidence intervals were calculated to compare quartiles. RAE was more prevalent in U17 compared to U20 χ243.865, p.001, V0.12; χ224.071, p.001, V0.09, respectively. For all positions, the number of female soccer players born in the first quarter of the year was higher than those born in the last quarter. In U17, RAE was statistically significant in all positions, while in U20 only defenders and midfielders distributions were significantly skewed. In conclusion, RAE is a critical issue to investigate in female soccer context, and age categories, playing position and continents seem such moderators of RAE that coaches and policy makers need to consider.

 Altyapılarda yetenekli sporcuların erken tespiti ve gelişimi, tüm spor dallarındaki kulüplerin ve ulusal spor yönetim organlarının öncelikli ilgi alanlarındandır. Sporcuların seçiminde ve gelişimsel süreçlerinin planlanması sırasındaki seçim yanlılığı, ele alınması gereken kritik bir noktadır ve rölatif yaş etkisi RYE bu bağlamda araştırılması gereken olgulardandır. Bu araştırmanın amacı U17 ve U20 FIFA Kadınlar Dünya Kupasında RYE prevalansını incelemek ve yaş kategorisi, oyun pozisyonu ve kıtaların rolünü bu bağlamda değerlendirmektir. Düzenlenen son üç U17 ve U20 FIFA Kadınlar Dünya Kupasına katılmış 2016 kadın futbolcu U171008, U201008 doğum ayı dağılımlarına göre değerlendirilmiştir. Çeyrekler arası farklılıklar Ki-Kare χ² uyum iyiliği testi kullanılarak analiz edilmiştir ve çeyrekleri karşılaştırmak için olasılık oranı OR ve  95 güven aralıkları hesaplanmıştır. RYEnin U17de U20ye göre daha yaygın olduğu tespit edilmiştir sırasıyla, χ243.865, p.001, V0.12; χ224.071, p.001, V0.09. Tüm pozisyonlar için yılın ilk çeyreğinde doğan kadın futbolcu sayısı son çeyreğinde doğan kadın futbolcu sayısından daha fazladır. U17de RYE tüm pozisyonlarda anlamlıyken, U20de sadece defans ve orta saha oyuncularının dağılımlarında önemli ölçüde farklılık tespit edilmiştir. Sonuç olarak, RYE, kadın futbolu bağlamında araştırılması gereken kritik bir konudur ve yaş kategorileri, oyun pozisyonları ve kıtalar RYE bağlamında antrenörlerin ve politika yapıcıların göz önünde bulundurması gereken unsurlardandır.
