Questions people ask about Sportgene Genetik

Questions about 'sports genes' (e.g., ACTN3, ACE) are common, but the scientific reality is sobering. Individual gene variants typically have small effects on elite performance – training, nutrition, recovery, and environment dominate. Most commercial tests rely on GWAS associations with low predictive power. A positive result for the 'sprint gene' ACTN3 RR does not guarantee top performance; many elite athletes carry other genotypes. Conversely, lacking an 'endurance variant' does not preclude high-level endurance. Evidence is mostly mechanistic or from GWAS, rarely from controlled intervention trials. A genetic test can serve as lifestyle curiosity but not as a medical or training decision tool. Beware of exaggerated marketing claims: no test replaces professional coaching or sports medicine. For serious performance optimization, rely on proven methods and consider genetic testing as an optional extra.
