Hancock, David J.; Ste-Marie, Diane M.; Young, Bradley W. – Research Quarterly for Exercise and Sport, 2013
Relative age effects (RAEs; when relatively older children possess participation and performance advantages over relatively younger children) are frequent in male team sports. One possible explanation is that coaches select players based on physical attributes, which are more likely witnessed in relatively older athletes. Purpose: To determine if…

Athletes born early within an annual youth age-group selection year are probably more likely to be selected for sports teams and talent development programs than those born later in that year. Overrepresentation of these relatively older athletes in youth and adult sport is known as the relative age effect (RAE). RAEs were found in these popular…

Okazaki, Fabio H. A.; Keller, Birgit; Fontana, Fabio E.; Gallagher, Jere D. – Research Quarterly for Exercise and Sport, 2011
In sports, the relative age effect (RAE) refers to performance disadvantages of children born late in the competition year compared to those with birthdays soon after the cutoff date. This effect is derived from age grouping, a strategy commonly used in youth sport programs. The purpose of age grouping is to decrease possible cognitive, physical,…

Participants were 483 athletes between 12 and 16 years old. The results showed that perceptions of both peer- and coach-generated climate…

Medic, Nikola; Starkes, Janet L.; Weir, Patricia L.; Young, Bradley W.; Grove, J. Robert – Research Quarterly for Exercise and Sport, 2009
The relative age effect refers to the performance-related advantage of being born early in a cohort or selection year. Until recently it was unknown whether the relative age effect generalizes across the lifespan. Medic, Starkes, and Young (2007) reasoned that the 5-year age categories that are widely used in masters-level sports to organize…
