Abstract Children born shortly before the cutoff date for age grouping in youth sport programs suffer from being promoted to higher age groups earlier than their later-born peers. Skewed birthdate distributions among participants in youth sport and professional sport leagues have been interpreted as the result of this disadvantage. A growing body of research shows that this Relative Age Effect in sport is a worldwide phenomenon and that it exists in many, but not all, competitive sports. Both…

Relative Age Effect: Beyond the Youth Phenomenon

The general presence of an RAE in Olympic athletes exists regardless of global classification, and this extends across selected categories of athletes (by gender), such as team versus individual sports, winter versus summer athletes, and sports using a ball versus those not use a ball.

Relative Age Effects: Implications for Leadership Development

Relative age effects (RAEs) have been widely studied in the contexts of education and sport over the past 25 years. The RAE phenomenon is concerned with identifying age (dis)advantages relative to

Relative age effect: beyond the youth phenomenon

The general existence of the relative age effect is found in Olympic athletes regardless of global classification and the findings suggest that coaching staff should be cognisant of the RAE when working with young athletes and should take relative age into consideration when evaluating a burgeoning athlete's abilities.

Relative age effect: implications for effective practice

Inductive analysis of the data showed that, while there was mixed evidence for the existence of RAEs across sports, the eradication of Raes was attributed to controllable features of the development environment.

Relative age effects on motor performance of seventh-grade pupils

Annual age grouping of children according to their birth year is a common practice of the educational systems of many countries. This variation in birth dates among children grouped in the same

The Relative Age Effect in Sport: A Developmental Systems Model

This paper reviews and summarizes the existing literature on relative age in sport, and proposes a constraints-based developmental systems model for RAEs in sport.

The Relative Age Effect Among Female Brazilian Youth Volleyball Players

Although not statistically significant, a larger percentage of players were born early in the competition year, and 67% were born in the first 6 months of the competitive year, which is the only indication in the literature of RAE among young female players.

Did the Relative Age Effect Change Over a Decade in Elite Youth Ski Racing?

Assessment of the magnitude of the RAE in youth ski racers aged 10–14 years has changed during the last decade by comparing the periods 2005–2009 and 2015–2019 indicated no change, emphasizing the robust nature of this phenomenon.

Are Summer‐born Children Disadvantaged? The Birthdate Effect in Education

Abstract Summer‐bom children did not perform as well as autumn‐born children on the APU Science Survey tests. There is bound to be some confounding of birthdate with length of schooling, but

The influence of relative age on success and dropout in male soccer players

Results indicated that youth players born from August to October (the early part of the selection year), beginning in the 6–8 year age group, are more likely to be identified as talented and to be exposed to higher levels of coaching, and to become involved professionally.

A New Factor in Youth Suicide: The Relative Age Effect

The present study demonstrates that the relative age effect is also a factor in youth suicide, and suggests that the higher incidence of youth suicide in the group of relatively younger school children may have resulted from poorer school performance, which in turn led to lowered confidence and self esteem.
