With the recent inclusion of surfing in the 2020 Olympic Games in Japan, there will be a number of surfing athletes vying for one of the twenty total available spots for their respective gender. The purpose was to evaluate relative age effects (RAEs) in surfing with consideration for specific developmental constraints. Elite competitive male surfers (n = 1590) were examined by birth month and subcategorized by competitive level, age groups, and geographical regions. The observed quarterly distribution was not significantly different (using χ; p>0.05) from expected for the overall group or any of the subcategories. However, an odds ratio of 1.85 (90% confidence interval: 1.08-3.14) was calculated for being born in the first semester of the year compared to being born in the second semester between top 34 athletes and the rest of the field. Despite consideration for individual, environmental, and task constraints in this study, the sport of surfing does not appear to have any observable RAEs at the professional level. Thus, surfing appears to be one of the few sporting activities included in the Olympic Programme with limited RAEs.
随着冲浪运动最近被纳入2020年日本奥运会项目，将有许多冲浪运动员争夺各自性别总共20个可用名额中的一个。目的是在考虑特定发展限制因素的情况下，评估冲浪运动中的相对年龄效应（RAEs）。对精英男子竞技冲浪运动员（n = 1590）按出生月份进行了检查，并按竞技水平、年龄组和地理区域进行了细分。观察到的季度分布与总体组或任何子类别预期的分布没有显著差异（使用χ检验；p>0.05）。然而，在前34名运动员与其他运动员之间，与出生在下半年相比，出生在上半年的优势比为1.85（90%置信区间：1.08 - 3.14）。尽管本研究考虑了个人、环境和任务限制因素，但冲浪运动在职业水平上似乎没有任何可观察到的相对年龄效应。因此，冲浪似乎是奥运项目中少数相对年龄效应有限的体育活动之一。
