What role does Longevity DNA Test play in Sport?

The Longevity DNA Test from MyBody-X analyzes genetic markers linked to aging processes, such as telomere maintenance, inflammation regulation, and collagen metabolism (e.g., rs1800012 in COL1A1). In a sports context, these markers could theoretically offer clues about recovery capacity, connective tissue integrity, or oxidative stress response. However, the evidence for direct performance or injury prediction is weak. Most associations come from population-based GWAS or mechanistic studies, not from randomized trials in athletes. Moreover, environmental factors (training, nutrition, sleep) far outweigh genetic predispositions. The test may serve as a general orientation but is not clinically validated for sport-specific decisions. Evidence grade: mechanistic/unclear. Caveat: do not base training or supplementation solely on these results.
