Oxygen consumption, locomotory-respiratory coupling and exercise-induced pulmonary hemorrhage in horses during the Paso Fino gait.

Background: Workload associated with the high frequency Colombian Paso Fino gait has not been evaluated.

Objectives: To determine the oxygen consumption (V̇O), heart rate (HR), stride frequency: breathing ratio, and hematology associated with the Paso Fino gait, including whether exercise-induced pulmonary hemorrhage (EIPH) occurs.

Animals: Eleven Paso Fino horses.
