Learning How Air Pollution Impacts Horses While Training

Studies show horses frequently are exposed to elevated air pollution at racetracks around the United States, and that when air pollution is elevated on the day of racing, all horses run slower. However, air pollution doesn’t just affect horses on racing days. Little is known about the health and performance of horses that repeatedly train outside during high pollution days. Researchers will analyze 10 years of air pollution and racehorse training/competition data to address this knowledge gap. The team also will share findings with horse health experts to help guide management recommendations for equine athletes during periods of elevated air pollution.
