Risks and limits of Sportgene Training

Sport gene tests claim to predict optimal training type, injury risk, or talent based on DNA variants like ACTN3 or ACE. The evidence for such predictions is weak to moderate at best. Most studies show small effect sizes, and lifestyle factors (training, nutrition, sleep) far outweigh genetic influences. No test can reliably determine whether someone will excel in endurance or power sports. Risks include false reassurance, unnecessary anxiety, and misallocation of training focus. Many commercial tests overstate their predictive power. For consumers, it's important to understand that these tests are not diagnostic and should not replace professional coaching or medical advice. The field of sport genomics is still emerging, and polygenic scores have limited accuracy. A more evidence-based approach is to use genetic information as one of many inputs, combined with physiological testing and personal response. For minors, ethical concerns about labeling and autonomy arise. In summary: sport gene training tests have significant limitations and should be approached with caution.
