Common mistakes around Sportgene Check

A common mistake with Sportgene Check tests is assuming that a single gene variant (e.g., ACE I/D or ACTN3 R577X) reliably predicts athletic performance or injury risk. The evidence is mostly GWAS-based with small effect sizes; many findings are not replicated or are population-specific. Users also often ignore that training, nutrition, sleep, and psychology have far greater impact than the tested SNPs. Another error is neglecting ancestry: a marker validated for Europeans may be meaningless in other ethnic groups. Confusing association with causation is widespread – a risk allele does not guarantee a performance limitation. Finally, these tests are not clinically validated and should not replace medical advice or professional coaching. Evidence: human-moderate/GWAS. Sources: none from provided context, so empty.
