Inside KER Research: What Is an Endurance Test?By Kentucky Equine Research Staff · September 15, 2014

One trial conducted at the Kentucky Equine Research facility is a sprint test. This test simulates a racing exercise bout and is used to investigate critical metabolism occurrences when horses perform high-speed exercise.

To conduct this test, Thoroughbred horses are galloped on a high-speed treadmill at 115% of maximal oxygen consumption until fatigued. The horses are carefully monitored and the test is stopped as soon as each horse indicates that it cannot maintain the desired speed.

During the test, indirect calorimetry is used to measure oxygen consumption and carbon dioxide production to ascertain maximal accumulated oxygen deficit (MAOD). In turn, anaerobic capacity is determined by MAOD. Information derived from sprint tests is applicable to Thoroughbred racehorses.
