The aim of the current research was to investigate the relative age effect (RAE) as a factor of basketball dropout. In order to do so, we examined the distribution of birth dates of young male (n=44,498) and female (n=30,147) French basketball players who have dropped out this sport during or at the end of the 2005-2006 season. χ(2) analyses showed an underrepresentation of dropouts among male players born early in the competition year and an overrepresentation among those born late in the "9-10 years old,""11-12 years old," and "13-14 years old" categories and in the first year of the "15-17 years old" category. Concerning girls, this asymmetry was observed across the same age categories. For both boys and girls, there was no biased distribution in the "7-8 years old" category. Findings of the present study confirm that the RAE should be taken into consideration in studies about sport dropout as a variable that may influence this phenomenon significantly.
本研究旨在探讨相对年龄效应（RAE）作为篮球运动员退役的一个因素。为此，我们研究了在 2005-2006 赛季期间或结束时退出这项运动的年轻男性（n=44498）和女性（n=30147）法国篮球运动员的出生日期分布。卡方分析表明，在“9-10 岁”、“11-12 岁”和“13-14 岁”以及“15-17 岁”年龄段和“15-17 岁”年龄段的最初一年，出生较早的男性运动员中，中途退出的人数较少，而出生较晚的运动员中，中途退出的人数较多。对于女孩来说，这种不对称性在相同的年龄组中也存在。对于男孩和女孩来说，“7-8 岁”这一年龄段的分布没有偏差。本研究的结果证实，RAE 应该在关于运动退役的研究中被视为一个可能显著影响这一现象的变量。
