Summary: | The aim of this study was to determine the serum activities of enzymes aspartate aminotransferase, creatine kinase and lactate dehydrogenase in Arabian horses submitted to exercise on high-speed equine treadmill. Eleven mature Arabian horse were training and submitted to Standard Incremental Exercise Test on high-speed equine treadmill. Venous blood samples were taken before exercise, immediately and 30 min, 60min, 3h, 6h, 24h, 3 days and 5 days after exercise. The serum activity aspartate aminotransferase, creatine kinase and lactate dehydrogenase were determined. The serum activies of AST, CK and LDH increase immediately and returned to baseline value 30 minutes after exercise. The AST enzyme activity increased at 12 hours and 24 hours, CK at 3 hours and 6 hours, and LDH at 24 hours after Standard Incremental Exercise Test.
Objetivou-se determinar a atividade sérica das enzimas aspartato aminotransferase (AST), creatina quinase (CK) e lactato desidrogenase (LDH) de cavalos da raça Árabe submetidos a exercício em esteira de alta velocidade. Onze eqüinos adultos da raça Árabe foram condicionados e submetidos ao Teste Padrão de Exercício Progressivo em esteira. Antes, imediatamente após o término do exercício, e nos momentos pós-exercício, 30min, 60min, 3h, 6h, 12h, 24h, 3 dias e 5 dias, foram coletadas amostras de sangue venoso para as determinações séricas das enzimas aspartato aminotransferase (AST), creatina quinase (CK) e lactato desidrogenase (LDH). As concentrações séricas da AST, da CK e da LDH elevam-se imediatamente e retornam a valores semelhantes ao de repouso 30 minutos após o término do Teste Padrão de Exercício Progressivo. A atividade enzimática da aspartato aminotransferase (AST) eleva-se de 12 horas a 24 horas, da creatina quinase (CK) de 3 horas a 6 horas e da lactato desidrogenase (LDH) 24 horas após o término do Teste Padrão de Exercício Progressivo. |
