Myths vs facts: Longevity DNA Test and Sport

Claims that a DNA test can accurately predict athletic performance or injury risk in the context of longevity are scientifically weak. Most commercial tests rely on single gene variants (e.g., ACTN3, ACE) whose effects on endurance or strength are small and overshadowed by lifestyle and environment. Longevity itself is a complex trait shaped by genes, diet, exercise, and social factors – no single test can capture this. Direct evidence for 'longevity sport' markers is lacking; many offerings are marketing-driven. A DNA test may provide rough hints but cannot replace personalized training or medical advice. Beware of overblown promises: predictive power is low, and misinterpretation is common.
