Myths vs facts: DNA Stoffwechseltest and Sport

Myths vs Facts: DNA Metabolism Test and Sports Myth: A DNA test can tell you exactly which sport is best for you. Fact: DNA metabolism tests can identify genetic variants related to muscle fiber composition (e.g., ACTN3), lactate metabolism, or recovery. However, effect sizes are small to moderate, and individual training outcomes depend on many non-genetic factors like nutrition, sleep, hormones, and training history. No consumer test provides a reliable sport recommendation. Most studies are in European populations, limiting generalizability. Marketing often overstates predictive power. A DNA test can be an additional piece of information but should not replace professional sports medicine advice or performance diagnostics. Safety note: If you have pre-existing conditions (cardiac, metabolic), consult a physician before changing your training regimen.
