In this paper, we describe two studies on the association among long-term developmental outcomes and relative age effects. To extend or compliment the cross-sectional work done previously, these studies take different approaches to investigate the association of relative age effects on long-term development. In the first, a retrospective approach is taken, while in the second, developmental data for players over a 4-year period is considered. In study 1 the association between relative age effects and later performance at the adult level is presented. The results show different patterns for females and males. In the second study, development during the national youth development system in handball, over four points in time, are presented. Again, changes over time in birth quartile distribution can be seen. These studies suggest relative age researchers should embrace longitudinal designs. These types of approaches would allow explorations of the association of other variables with the observed relative age effects.
在本文中，我们描述了两项关于长期发育结果与相对年龄效应之间关联的研究。为了扩展或补充之前所做的横断面研究工作，这些研究采用了不同方法来调查相对年龄效应与长期发育之间的关联。第一项研究采用回顾性方法，而第二项研究则考虑了球员四年期间的发育数据。在研究1中，呈现了相对年龄效应与成年水平后期表现之间的关联。结果显示，女性和男性呈现出不同模式。在第二项研究中，展示了手球国家青年发展体系中四个时间点的发育情况。同样，可以看到出生四分位数分布随时间的变化。这些研究表明，相对年龄研究人员应采用纵向设计。这类方法将有助于探索其他变量与观察到的相对年龄效应之间的关联。
