Resumen


RESUMEN

El objetivo de este estudio fue analizar el efecto de la edad relativa (RAE) en el proceso de selección nacional de triatletas (n = 1321) durante las temporadas 2013-2015. La muestra fue divida por categorías y sexo. Cada una fue subdividida en 4 cuartiles según la fecha de nacimiento. Las diferencias fueron analizadas mediante la prueba no paramétrica Krustal-Wallis. Para la comparación múltiple se utilizó U de Mann Whitney. Los resultados mostraron que el rendimiento en las pruebas analizadas presentaba una mejor tendencia en aquellos deportistas nacidos en el primer cuartil del año para el sexo  masculino. En esta línea, los atletas nacidos en la última parte mostraron un peor rendimiento general. Estos resultados fueron menos consistentes para el sexo femenino. Este trabajo ha puesto de manifiesto la influencia del RAE en los procesos de identificación de talentos y la estructura competitiva, sugiriendo su consideración en los procesos de selección.

PALABRAS CLAVE: fecha de nacimiento, rendimiento, talento deportivo, maduración

ABSTRACT

The aim of this study was to analyze the influence of relative age effect on the selection process in triathlon (n = 1321). The sample was divided by category and gender. Each category was allocated into four quartiles - based on date of birth according to the selection year. The Krustal-Wallis and Mann-Whitney test were used to analyze the intra-categorical and intra-gender differences. The results showed a better performance trend in those athletes that were born in the first quartile. In contrast, athletes that were born in the latter part of the year showed poorer overall performance and a lower score in the point scale. However, these results were less consistent for females. This work has shown a significant loss of potential triathlon talent due to the influence of RAE in the selection process and competitive structure.

KEYWORDS: date of birth, performance, talent selection, mature
