Equine athletes, the equine athlete's heart and racing success

Lesley E. Young

doi:10.1113/eph8802615

Abstract

Our recent data have confirmed that maximum oxygen delivery in racing Thoroughbreds is positively correlated to left ventricular mass measured by echocardiography. A similar, but weaker relationship also exists between left ventricular mass and Timeform performance rating in commercial racehorses. The relationship of the Thoroughbred heart to racing success and the special problems that selective breeding for aerobic capacity have had in this species are reviewed in this article. Experimental Physiology (2003) 88.5, 659-663.
