Annual age-grouping is a common organizational strategy in sport. However, such a strategy appears to promote relative age effects (RAEs). RAEs refer both to the immediate participation and long-term attainment constraints in sport, occurring as a result of chronological age and associated physical (e.g. height) differences as well as selection practices in annual age-grouped cohorts. This article represents the first meta-analytical review of RAEs, aimed to collectively determine (i) the…

Examination of youth football programs with early evidence for considering alternative methods of organising players indicates using only one developmental criterion for organising players is associated with relative age effect, whereas approaches accounting for multiple variables are not associated with RAE.

The impact of negative outcomes from RAE appears to be greater among German age group swimmers, compared to previous reports on Australian as well as Portuguese cohorts, because the RAE was prevalent over a longer time period.
