Talent is essential for success in the sports. A successful sprinter would probably never attain similar results in marathon running. Genes play an important role here; thus, it makes sense to encourage our kids to enter those sports where their chances for success are the greatest. The ACTN3 gene plays an important role in this context. A mutated or inactive form of the gene is more prevalent in endurance sports. The opposite holds true for athletes who require strength and speed; they more often possess the active form.
