I searched my profile at 23&Me and got this:
Athletic performance can be influenced by a number of factors, some of which are genetic. Genes determine between 20-80% of the variation in traits like oxygen intake, cardiac performance, and muscle fiber composition. To date, more than 150 genes have been linked to different aspects of physical performance. One of the clearest associations is seen with a gene called ACTN3 that is normally turned on in a type of muscle fiber used for power-based sports. A single SNP can turn this gene off. While this genetic change does not cause any health effects, it may contribute to whether you are a sprinter or a marathoner.
My DNA: Two working copies of alpha-actinin-3 in fast-twitch muscle fiber. Many world-class sprinters and some endurance athletes have this genotype.
Note - may my 2 working copies could have helped more if I had started using them at an earlier age?
