Resumen

El concepto de efecto de edad relativa se refiere a las consecuencias de las diferencias físicas y psicológicas que pueden existir entre los nacidos antes o después dentro del mismo año calendario. El objetivo del presente estudio fue examinar este fenómeno en el fútbol profesional internacional, identificando las influencias del continente. La muestra comprendió 6448 sujetos de 225 equipos (115 UEFA y 110 CONMEBOL) de las Ligas de fútbol profesional (PFL). El análisis estadístico se basó en la prueba de Chi-cuadrado (X2) seguido de los oddsratios (OR) y la estimación de intervalos de confianza del 95%. Los principales resultados muestran un RAE más alto en las ligas CONMEBOL (OR = 2, 23) que en las ligas de la UEFA (OR = 1,95). Además, en todas las ligas analizadas, excepto en la Premier League de Inglaterra, hubo una sobrerrepresentación de las personas nacidas en los primeros meses del año. Podemos concluir que el efecto de la edad relativa es consistente y existe en el fútbol internacional.
