Testosterone training often refers to the use of testosterone or its precursors for performance enhancement – this is problematic from both medical and sports law perspectives. Without medical indication (e.g., confirmed hypogonadism), exogenous testosterone can disrupt natural hormone balance, leading to testicular atrophy, infertility, increased cardiovascular risk, mood swings, and liver damage. It is also banned as doping in competitive sports. MyBody-X DNA tests are not suitable for measuring testosterone levels or guiding training; they do not provide medical diagnosis.

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.","area":"gesundheit","canonical_id":"gesundheit:canonical-38239fbaa248c4c64c6f89c8","id":"public-90ee2b44a98a1e77fcff1fd9","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Risks and limits of Sportgene Training","score":27.01333544,"snippet":"Sport gene tests claim to predict optimal training type, injury risk, or talent based on DNA variants like ACTN3 or ACE.

No large randomized trial proves that DNA-based training plans outperform standard evidence-based advice.
