Cardiac Recovery Time in Endurance Horses Evaluated
In a recent study, Céline Robert, DVM, PhD, a researcher and lecturer at the National Veterinary School of Maisons-Alfort in France; Eric Barrey, a senior research specialist at the French National Institute for Agricultural Research; and colleagues determined that CRT appears to be a reliable indicator of a horse’s fitness level and likelihood of being eliminated from a race.
In endurance competitions, horses have 20 minutes after arriving at a vet gate to attain a heart rate of 65 beats per minute (bpm). “In this study, we showed that the majority of horses were recovering the value of 64 bpm in a few minutes and that recovery times longer than 11 to 13 minutes were indicators of a high risk of elimination on the next phase,” Barrey said.
Robert and Barrey encourage veterinarians and riders to consider recovery times greater than 13 minutes as a warning sign of a
