Effect Of Age

  El pádel ha pasado a ser a uno de los deportes más practicados en España. El propósito de este estudio fue evaluar el Efecto Relativo de la Edad (RAE) en los jugadores del circuito de World Pádel Tour (WPT) (n=395) teniendo en cuenta el mes de nacimiento, género, nacionalidad, edad y ranking. La distribución trimestral observada no fue significativamente diferente (χ2; p>.05) a la esperada para el grupo general o para cualquiera de las subcategorías analizadas. Por tanto, no parece confirmarse un efecto de la edad relativa en los jugadores profesionales de pádel analizados, considerando el ranking, género y nacionalidad, a diferencia de lo que ocurre en otros deportes de raqueta. En este sentido, esta investigación constata que la fecha de nacimiento no es un factor relevante en el circuito de WPT y confirma que llegar a la élite del pádel no se basa exclusivamente en factores físicos y antropométricos.  Abstract: Padel has become one of the most practiced sports in Spain. The purpose of this study was to evaluate the Relative Effect of Age (RAE) in the World Padel Tour (WPT) circuit players (n = 395) taking into account the month of birth, gender, nationality, age and ranking. The quarterly distribution observed was not significantly different (χ2; p> .05) than expected for the general group or for any of the subcategories analyzed. Therefore, it does not seem to confirm an effect of relative age on professional padel players analyzed, considering the ranking, gender and nationality, unlike what happens in other racket sports. Thus, this investigation confirms that the date of birth is not a relevant factor in the WPT circuit and confirms that reaching the elite of the paddle that is not based exclusively on physical and anthropometric factors.

Athletes born at the beginning of the year may present the advantage of physical characteristics, motor ability or cognitive knowledge that could increase their chances for selection against their peers. This circumstance could lead to the over-representation of older athletes in an age-defined competition which is commonly referred to as relative age effect (RAE). Although, a number of studies have demonstrated that RAE is apparent in youth soccer, such studies barely investigates the performance advantage that may likely exists across the birth month of the athletes. The current study aims to determine the presence of RAE in the under 16 Asian Football Confederation Championship (AFC), investigate the effect of RAE on the team qualification success as well as ascertain the existence of RAE in the playing position amongst the soccer players. Data of the 2018 AFC under 16 qualifications matches were obtained from the AFC. A total of 719 players from 32 countries participated in the qualification competitions. Chi-square for goodness fit is used to determine the existence of the RAE across the players’ month of birth while logistic regression is applied to analyze the differences of the quartiles’ distribution with respect to the quartile, qualification status (qualifier or non-qualifier) as well as the playing position of the players. The results demonstrate the presence of RAE in the AFC under 16 soccer tournaments [χ2(4) = 21.53; p < 0.001] with the largest number of older players dominating the qualified team. Likewise, a substantial difference is observed with regards to the quartile and various playing position of the players p < 0.05.

Relative Age Effect

El mes de nacimiento tiene importantes implicaciones en el desarrollo del talento deportivo, especialmente para algunos deportes y grupos de edad. El objetivo del estudio fue analizar el efecto de la edad relativa -EER- en jóvenes triatletas. Para ello, se identificó el cuartil de nacimiento de 160 triatletas cadetes que participaron en liga de triatlón valenciana durante el periodo 2012-2016, clasificando, por un lado, aquéllos que formaron parte de los programas de tecnificación y, por otro, los que obtuvieron medalla. Se aplicaron los test estadísticos Chi-cuadrado, Kruskal-Wallis y el test de contraste de proporciones a través de SPSS®y Microsoft Excel®. Los resultados mostraron que los triatletas nacidos en el primer cuartil del año predominan en los programas de tecnificación en triatlón y obtienen más medallas que el resto, especialmente de oro.Abstract. The month of birth has important implications for the development of sports talents, especially for some sports and age groups. The aim of the study was to analyze the effect of relative age -RAE - in young triathletes. For this reason, during the period 2012-2016 the birth quartile of 160 young triathletes who participated in the Valencian Triathlon League was identified, categorizing those who took part in high performance programs on one side, and on the other those who achieved medals. Chi-square, Kruskal-Wallis, and proportion contrast tests were applied through SPSS® and Microsoft Excel®. The results showed that triathletes born in the first quartile of the year predominate in triathlon high performance programs and win more medals than the rest, especially gold ones.

The aim of this study was to evaluate the differences on motor competence between boys and girls aged 4 years old and investigate the existence of Relative Age Effect on their motor competence. In total, 132 preschool children were evaluated, of whom 60 (45.50%) were girls and 72 (54.5%) were boys. The distribution of the participants was from quarter 1 [n = 28 (21.2%)], quarter 2 [n = 52 (39.4%)], quarter 3 [n = 24 (18.2%)], and quarter 4 [(n = 28 (21.2%)], respectively. The Movement Assessment Battery for Children-2 (MABC-2) was used to collect the data. The data show the main effects on quarter of birth factor in manual dexterity (MD; p < 0.001), in aiming and catching (A&C; p < 0.001), in balance (Bal; p < 0.001) and in total test score (TTS; p < 0.001). There are also statistical differences on gender factor in MD (p < 0.001) and in TTS (p = 0.031). A significant effect was also found in the interaction between two factors (gender and quarter of birth) in MD (p < 0.001), A&C (p < 0.001), and Bal (p < 0.001). There are differences in all the variables studied according to the quarter of birth and only in manual dexterity and in the total score if compared according to gender (the scores are higher in girls).
