What is the secret of power sport athletes? The worlds elite power sport athletes- including short-distance runners & power-lifters- may all have something in common: A specific gene variant. However, this gene variant doesnt seem to exist in people who arent athletes, nor in elite endurance athletes according to the findings, published in the Journal of Strength and Conditioning Research. Researchers found that 40% of the power sport athletes had two copies of the C allele on the AGT gene (to have two copies of the C allele means both parents passed along their C alleles to the offspring). Meanwhile, just 13% of elite endurance athletes and 18% of the nonathletes had this particular genotype. However, researchers did not find any genotype differences between athletes who ended up winning medals in the world competitions, versus those who did not medal. The AGT gene is known to play a role in the regulation of body salt, fluid balance and blood pressure. While researchers said more study is needed before determining how exactly a CC genotype can affect strength, they noted that it could potentially promote angiotensin II production, which affects muscle performance.
