Abstract

Relative age effect is a worldwide phenomenon referring to the subtle age-related (dis)advantages of athletes in the same age category, particularly in soccer and ice-hockey. Although well-established knowledge has been achieved to a certain extent, a need for further research is still valid considering different demands of each sport and possible differences in the course of time. The purpose of this study was to investigate the participation trends among elite figure skaters in the world regarding relative age effect, and to determine whether a decade has made a difference. The study sample was composed of 2313 figure skaters competing between 2009-10 and 2018-19 seasons. They were categorized into four quartiles according to their birth months. Total and season by season analyses were conducted to project any possible seasonal effect over a decade. Chi-square (χ²) goodness-of-fit tests were used to determine asymmetries in distributions, and odds ratios (OR) and 95% confidence intervals were used to compare quartiles with each other. Effect sizes were calculated using Cramer’s V (V). The results differed for disciplines and genders. Relatively older male skaters in pairs discipline were significantly overrepresented (χ² = 8.528, p = 0.036, V = 0.11) and a trend favoring relatively younger skaters was determined in men’s singles discipline through the last three seasons. Season-based analyses revealed no relative age effect except for the last three seasons. In conclusion, disciplines of figure skating seem to have complex and different demands regarding relative age effect, and time seems to become a determinant for further studies.
花样滑冰的参与趋势重新审视了相对年龄的影响:十年有影响吗?
相对年龄效应是一种世界范围内的现象,指的是同一年龄段的运动员,尤其是足球和冰球运动员,在年龄方面的微妙(dis)优势。虽然在一定程度上已经有了完善的认识,但考虑到每项运动的不同要求以及时间的推移可能存在的差异,还需要进一步的研究。本研究的目的是调查世界优秀花样滑冰运动员在相对年龄影响下的参与趋势,并确定十年是否会产生差异。研究样本由2009-10赛季和2018-19赛季的2313名花样滑冰运动员组成。他们根据出生月份被分为四个四分之一。进行了总体和逐季分析,以预测十年来任何可能的季节性影响。使用卡方(χ²)拟合优度检验来确定分布中的不对称性,并使用比值比(OR)和95%置信区间来相互比较四分位数。效应量是用克莱默V (V)来计算的。不同学科和性别的结果不同。在双人滑项目中,年龄相对较大的男子选手明显过多(χ²= 8.528,p = 0.036, V = 0.11),在过去三个赛季中,男子单人滑项目中有偏向相对年轻选手的趋势。基于季节的分析显示,除了最近三个季节外,没有相对年龄的影响。综上所述,花样滑冰各学科对相对年龄效应的要求复杂多样,时间似乎成为进一步研究的决定因素。
