Preliminary investigation results in physiological traits and changes due to exercise (horse jumping competition) in equines in Colombia are presented. 24 horses were selected (Silla argentina, PSI and crossbred) at the National Army Cavalry school, where cardiac and respiratory rate, creatinkinase (CK), lactic dehydrogenase (LDH) and lactic acid were monitored. Horses jumped obstacles of 1.10 to 1.20 m, and samples were taken before, immediately after and six hours following exercise. Cardiac rate was determined using a Polar S625 cardiac monitor; for respiratory rate, stethoscopes and blood samples were analyzed by spectophotometric methods. For muscle enzymes and lactic acid, statistic analysis (ANAVA) was carried out and for cardiac and respiratory rates descriptive statistics were performed. Results showed that lactic acid and creatinkinase had a notorious change with exercise, while lactic dehydrogenase had no alteration. Cardiac and respiratory rate had a significant increase after exercise, but return to normal in the next six hours. Lactic acid increased in a significant way and return to normal six hours after, unlike what other authors have reported. The research shows that changes are maybe due to type and time of exercise or altitude. Further research is necessary to complement topic related studies.

Keywords : Lactic acid; CK; LDH; equines; horse jumping competition; cardiac frequency; respiratory frequency.
