Questions people ask about Sportgene Basis

The 'Sportgene Basis' is a DNA test that analyzes genetic variants linked to athletic performance, endurance, strength, or recovery. Typical genes include ACTN3, ACE, PPARGC1A. However, the scientific evidence for such tests is weak: most variants have small effect sizes and do not reliably predict individual response. GWAS studies show associations but not causation. No randomized controlled trials demonstrate that using these tests improves training outcomes. Many companies overstate the utility for marketing. A test may satisfy curiosity but should not be the sole basis for training or nutrition decisions. Personalized training remains multifactorial and requires more than a single SNP profile.
