摘要

相对年龄效应(Relative Age Effect, RAE)这个问题在学术界和教练界都有很长的研究、讨论和发表,近年来在各种运动项目中的研究数量显著增加。本研究的目的是验证捷克男性(n = 6552)和女性(n = 4131)青少年网球运动员中RAE的存在,并确定男女运动员在出生日期效应上可能存在的差异。该研究是在捷克网球协会(CTA)数据库中2007-2016年注册的U14年龄段的球员中进行的;运动员被分成三个小组(“排名”、“前100名”、“前10名”)。研究数据采用描述性统计和推理统计的方法进行分析:相对频率和绝对频率,卡方拟合优度检验()和独立性的卡方检验(),使用效应量(ES指数w)。在所有三个亚组中,男性和女性青少年球员的频率从Q1到Q4呈下降趋势。在整个2007-2016年期间,只有“前10名”男性亚组显示出显著且强烈的RAE (RAE显著,其他两个亚组的ES较小或微不足道)。在女性玩家中,RAE在所有三个亚组中都很显著(ES很小或微不足道)。在“前100名”和“排名”中,男性玩家的RAE的性别差异是显著的(ES在所有三个子组中都很小或微不足道)。从短期和长期来看,RAE对运动员的运动发展都有重要的影响;因此,建议教练和专业人士都要注意这个问题。RAE对体育运动的影响,即运动员出生日期分布的不均匀,尤其在青少年运动员中更为明显,往往会显著影响他们的运动发展和职业生涯。

The Relative Age Effect in Czech U14 Male and Female Tennis Players in 2007–2016
The issue of the Relative Age Effect (RAE) has been long researched, discussed and published both in the academic and coaching community and the number of studies on it in various sports has significantly grown in recent years. The aim of this study was to verify the existence of RAE among Czech male (n = 6552) and female (n = 4131) junior tennis players and to identify possible differences in birthdate effect between male and female players. The research was carried out in players registered in the years 2007–2016 in the U14 age category in Czech Tennis Association (CTA) database; the athletes were divided into three subgroups (‘Ranked’, ‘Top 100’, ‘Top 10’). Research data were analysed by the methods of descriptive and inferential statistics: relative and absolute frequency, chi-square goodness of fit test () and chi-square test of independence () with the use of effect size (ES index w). A declining tendency of frequencies from Q1 to Q4 between male and female junior players was proven in all three subgroups.In the whole period of 2007–2016, a significant and strong RAE was demonstrated only in the ‘Top 10’ male subgroup (RAE was significant and ES was small or trivial in the other two subgroups). Among the female players, RAE was significant in all three subgroups (ES was small or trivial). Gender differences in RAE in favour of male players were significant in ‘Top 100’ and ‘Ranked’ (ES was small or trivial in all three subgroups). In the short and long term, RAE can have significant implications for the sport development of athletes; both coaches and the professional public can therefore be recommended to pay attention to this issue. The impact of RAE in sport, i.e. the uneven distribution of athletes’ birthdates, is more pronounced especially among junior athletes and often significantly affects their sports development and career.
