Significance We found that hundreds of years of selection by humans have produced sport-hunting breeds of superior speed and athleticism through strong selection on multiple genes relating to cardiovascular, muscle, and neuronal functions. We further substantiated these findings by showing that genes under selection significantly enhanced athleticism, as measured by racing speed and obstacle course success, using standardized measures from dogs competing in national competitions. Overall these results reveal both the evolutionary processes and the genetic pathways putatively involved in athletic success.
