Talent tests sold to parents, and what the research behind them actually supports.

Why this topic Youth sport genetic testing is marketed hard and regulated barely at all.

A muscle fiber splitting into two paths, one built for a short powerful burst, one built for sustained endurance

Is There Really a "Sprinter Gene"? Yes — Meet ACTN3.

Every gym-culture video insists some people are just "built" for lifting heavy and others for endurance. There…

Solid lines are connections this site curates. Dashed lines mean the two ends share a research paper — worth knowing, and not a claim that one explains the other.

How this was counted

Europe PMC, title and abstract only, searched for “elite athlete”, “sports performance”, “muscle strength”, “injury risk” alongside each published rsID. Full text was not counted: it returns every paper with an rsID buried in a supplementary table. Recounted monthly.

Questions about Sport and performance

What is Sport and performance?

Sport and performance is this site's topic page for athletic-genetics research — the talent tests sold to parents, and what the underlying research actually supports.

Can a genetic test predict whether a child will become an elite athlete?

No. Talent tests are sold to parents on the promise of prediction, but the underlying research does not support picking a future elite athlete from a variant — a co-mention here is not a talent score.

Why is sport and performance a topic on this site now?

Youth sport genetic testing is marketed hard and regulated barely at all, which is exactly the gap this page exists to be honest about.

How does this site decide which variants are linked to sport and performance?

Europe PMC is searched for elite athlete, sports performance, muscle strength or injury risk appearing in a paper's title or abstract alongside a published rsID, recounted every month.
