What do studies say about Sportgene Senioren?

Scientific evidence on 'sports genes' in seniors is limited. Some studies (e.g., ACTN3 R577X and ACE I/D polymorphisms) show weak associations with muscle strength, endurance, or recovery in older adults. However, effect sizes are small and strongly overshadowed by training, nutrition, and lifestyle. A genetic test cannot replace individualized exercise prescription – it only provides statistical probabilities. MyBody-X DNA tests are marketed as lifestyle products, not diagnostic tools. For seniors, a medical check-up before starting exercise is far more important than any genetic analysis. The evidence does not support personalized sport recommendations based on genetics alone.
