Sports Genomics: Athletics
Athletics — encompassing sprinting, middle-distance running, long-distance running, jumping, and throwing — is one of the most genetically studied sports in the world. Research consistently shows that genetic factors contribute to more than 50% of the variation in athletic performance between individuals.
Key Genetic Traits for Athletics
ACTN3 (Sprint/Power) — the “speed gene”; the RR genotype is associated with fast-twitch muscle fibres and sprint/power performance; the XX genotype is associated with endurance performance
ACE (Endurance) — the I allele is associated with endurance performance; the D allele is associated with sprint/power performance
PPARGC1A (Aerobic Capacity) — influences mitochondrial biogenesis and VO2 max, a key determinant of endurance performance
COL1A1 and COL5A1 (Injury Risk) — influence tendon and ligament strength, affecting susceptibility to soft tissue injuries
IL6 and CRP (Recovery) — influence inflammatory response and recovery time after intense training
Sprint vs Endurance — What Your Genes Say
Elite sprinters and elite marathon runners have distinctly different genetic profiles. Understanding whether you are genetically predisposed to power/sprint or endurance activities allows you to choose the right athletic discipline, training programme, and recovery strategy — maximising your potential and reducing injury risk.
