Risks and limits of Sportgene Alltag

The Sportgene Alltag test from MyBody-X analyzes common genetic variants such as ACTN3 (the 'sprint gene') and ACE (endurance gene), which have been associated with athletic performance in studies. However, effect sizes are generally small, and the predictive power for individual injury risk or recovery ability is limited. Injuries depend on many factors: training load, technique, nutrition, sleep. Recovery is influenced by cortisol, inflammatory markers, and lifestyle – not genes alone. MyBody-X does not offer a specific test for stress resilience (COMT/BDNF), as seen in other contexts. The test can provide orientation but is not a medical diagnosis or training prescription. Evidence is mostly based on GWAS and mechanistic studies; clinical prediction is unproven. Be cautious of overblown claims: a genetic test cannot replace professional coaching or medical evaluation for recurrent injuries.
