Zusammenfassung
El propósito de este estudio fue identificar la existencia del Efecto de la Edad Relativa (EER) en el fútbol base en clubes de elite y clubes con un nivel inferior en España. El EER también fue analizado dentro de cada categoría federativa o grupo de edad (Sub-8 a Sub-19) y dentro de cada categoría de equipo teniendo en cuenta el nivel de experiencia deportiva (equipos A, B, C y D), de acuerdo con el tipo de club. Todos los jugadores (n = 1862) pertenecían a ocho clubes de fútbol españoles y 114 equipos. Las fechas de nacimiento se categorizaron en cuartiles. Los resultados obtenidos con la prueba de Chi-cuadrado revelaron la existencia de un EER de gran tamaño en el grupo Elite, mientras que en el grupo de nivel inferior este efecto fue medio. Además, los resultados muestran diferencias significativas en el grupo Elite en todas las categorías de edad, mientras que en el grupo de nivel inferior solo se observaron en las categorías Sub-14, Sub-16 y Sub-18. Con respecto a la categoría de equipo, mientras que el efecto se observó en el grupo Elite en todos los equipos, en el grupo de nivel inferior solo se observó en los equipos A y B. Como conclusión, el EER es más pronunciado en los clubes Elite, incluso comenzando en la categoría Sub-8. Sin embargo, en los clubes de nivel inferior, donde el objetivo no es solo el rendimiento, se retrasa.
