The relative age effect (RAE), within the sporting scope, refers to the possible advantages of participation and performance of athletes born in the first months of the year of selection in relation to others within the same age category. The aim of the present study was to investigate the RAE in girls' volleyball players participating in the U-18 World Championship, analysing the differences between the medal teams and other teams in the tournament, and considering this phenomenon in relation to the continents. Data collection was obtained from the website of the International Volleyball Federation with a sample made of 1654 youth players in the last six world championships (2007, 2009, 2011, 2013, 2015 and 2017). A greater representation of athletes born in the first months of the year of all the world championships was observed. In the comparison among the continents, it was observed that in Africa, there was a more equal distribution of quartiles compared to America, Asia and Europe. It should be noted that there was a higher percentage of medalist athletes born at the beginning of the year in comparison to the countries that placed in the last three positions of the championship. Therefore, in U-18 female volleyball, there is an advantage to have the closest birth age at the beginning of the competitive biennium.
在体育领域，相对年龄效应（RAE）指的是在选拔年份的前几个月出生的运动员，相较于同一年龄组内的其他运动员，在参与度和表现方面可能具有的优势。本研究的目的是调查参加U-18世界锦标赛的女排运动员中的相对年龄效应，分析奖牌队伍与比赛中其他队伍之间的差异，并从各大洲的角度考虑这一现象。数据收集自国际排球联合会的网站，样本包括过去六届世界锦标赛（2007年、2009年、2011年、2013年、2015年和2017年）中的1654名青年运动员。观察到在所有世界锦标赛中，出生在当年前几个月的运动员占比更大。在各大洲的比较中，观察到与美洲、亚洲和欧洲相比，非洲四分位数的分布更为均衡。需要注意的是，与在锦标赛中排名最后三位的国家相比，年初出生的奖牌获得者运动员的比例更高。因此，在U-18女子排球比赛中，在竞争双年开始时拥有最接近的出生年龄具有优势。
