Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Follow-up moderator analyses identified age category, skill level and sport context as moderators of RAE magnitude. → Cobley 2009

Evidence¶

Cobley 2009¶

Cobley, S., Baker, J., Wattie, N., McKenna, J. (2009). Annual Age-Grouping and Athlete Development. Sports Med 39, 235–256. https://doi.org/10.2165/00007256-200939030-00005

q3 · i? · quant-synthesis · r2

Follow-up moderator analyses of the meta-analyzed samples identified three moderators: "age category, skill level and sport context". No moderator effect-size values are printed in the available text.

"Follow-up analyses identified age category, skill level and sport context as moderators of RAE magnitude."

Discussion¶

Learner Variables¶

Age and Developmental Stage — moderator: an instructional effect differs with it

RAEs are consistently prevalent across sports but with small effect sizes — related
RAE effect size increases linearly with relative age differences — related
Adolescent males at representative level in highly popular sports are most at risk of RAE inequalities — a narrower finding that bears on this claim
RAE mechanisms and generalization to female and culturally diverse contexts remain unconfirmed research needs — related
