What should I know about Sportgene Test?

The Sportgene Test is a direct-to-consumer (DTC) genetic test that claims to reveal athletic predispositions such as endurance or power. However, the scientific evidence is weak. Athletic performance is highly polygenic and influenced by environment, training, and nutrition. Single gene variants (e.g., ACTN3, ACE) have small effect sizes and are not predictive on their own. Most DTC sport tests lack robust validation and are based on limited or population-specific studies. The evidence level is marketing/unclear. You should not change your training or diet based solely on such results. For personalized advice, consult a sports medicine professional. These tests may be fun but are not reliable for performance optimization.
