Questions people ask about Sportgene Test

Sport gene tests often claim to predict endurance, power, or injury risk based on single DNA variants like SIRT1 or ACTN3. However, the scientific evidence is generally weak: effect sizes are small, findings come from observational studies, and they do not reliably translate to athletic performance. A test may indicate a slight tendency but cannot determine whether someone will be a better endurance athlete. Marketing often overstates these links. Lifestyle factors like training, nutrition, and recovery are far more important. Gut microbiome tests can show inflammation markers (e.g., IL1B) and diet-related diversity, but clinical validity for performance optimization is limited. A sport gene test should be seen as an informative extra, not a decision-making tool. Be cautious of overblown claims: no test replaces personalized coaching or medical advice.
