Genes may determine an athlete’s sport.
A gene called ACTN3 is a protein molecule that is found in fast twitch fibers in the body. This gene stabilizes the filaments that make up muscles. Mutations in this gene can mean athletes will not perform well in events that require fast twitch fibers like sprinting and power lifting. Athletes who have the mutation usually train, qualify, and compete in endurance-based events instead.
