Abstract Although the relative age effect has been widely observed in youth sports (Musch & Grondin, 2001), it is unclear whether it generalizes across the lifespan. The purpose of this study was to examine the relative age effect among a population of Masters athletes using archived data. Two successive studies examined the frequency of record-setting achievements (Study 1) and the frequency of participation entries (Study 2) at the US Masters track-and-field and swimming championships as a… 

Gender, age, and sport differences in relative age effects among US Masters swimming and track and field athletes

Results showed that a participation-related relative age effect in Masters sports is stronger for males, that it becomes progressively stronger with each successive decade of life, and that it does not differ across track and field and swimming.

Participation-related relative age effects in Masters swimming: A 6-year retrospective longitudinal analysis

Examination of participation rates of Masters swimmers as a function of an individual's constituent year within any 5-year age category over a period of 6 years indicated that a participation-related relative age effect was observed among swimmers who competed in either at least one championship or at least three championships.

Constituent Year Effect in Masters Sports: An Empirical View on the Historical Development in US Masters Swimming.

Findings suggest that the 5-year age categories may not provide an equal competitive opportunity especially for relatively older athletes as for those who are relatively younger, but may encourage more strategic periodized training and participation.

The Constituent Year Effect: Relative Age Disparities in Australian Masters Track and Field Athletic Participation

The results demonstrate that despite masters sport being an avenue for promotion of participation and overall health, there is potential for improving how competitive organizational strategies are implemented given the recurring intermittent patterns of participation associated with five-year age brackets which are likely to compromise benefits.

The Constituent Year Effect in European Track and Field Masters Athletes: Evidence of Participation and Performance Advantages.

The results indicated that a participation-related constituent year effect was observed and Masters athletes in their first year of any 5-year age category won significantly more medals than expected based upon observed participation rate.

Relative Age Effect in Masters Sports

It is concluded that the relative age effect exists in many sports including baseball, cricket, ice hockey, soccer, swimming, and tennis; across a number of countries; and at various levels of competition (i.e., varying from professional young adult athletes to top-level adolescents).

Linear Decrease in Athletic Performance During the Human Life Span

Results showed an accelerated decline beyond the age of 70 in sprint, middle- and long-distance running, while in throwing and jumping disciplines the performance continued a linear decline.

Perceptions of five-year competitive categories: model of how relative age influences competitiveness in masters sport.

There are at least five psycho-social and physical factors that may explain why relatively younger masters athletes are more likely to perform better and to participate more in masters competitions than relatively older masters athletes.

The relative age effect among elite youth competitive swimmers

Findings of this study show that a higher number of swimmers, particular males, are born in the first two quarters of the year, although there is mostly no effect of seasonal birth date on performance differences within the top 50 swimmers.

Career-Span Analyses of Track Performance: Longitudinal Data Present a More Optimistic View of Age-Related Performance Decline

The longitudinal data showed that running performance declined with age in a more linear fashion than did cross-sectional data, and graphical trends showed that the moderation of age-related decline appeared greater for the longitudinal 10 km performances than for the 1500 m event.

Declines in physiological functional capacity with age: a longitudinal study in peak swimming performance.

The present longitudinal findings indicate that swimming performance declines progressively until age 70, where the decrease becomes quadratic and the rates of the decline in swimming performance with age are greater in a long-duration than in a short-duration event.

Masters Athletes

Performance improvement in the masters athlete requires the same commitment to hard training that it requires from younger athletes, with some modifications for changes that are associated with aging.

There are gender differences in the relative age effect of 17-year-old elite female and male soccer players, which may be explained by a complex interaction of biological and maturational differences with socialization influences.

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.
