Abstract
This study aimed to evaluate the muscle changes and the strength of horses, Quarter Horse, athletes submitted to sprint (300 meters) with the use of serum glucose reviews, lactate, creatine kinase and aspartate aminotransferase. For the evaluation, 21 horses were used in the Quarter Horse breed, aged 2 and 4 years old, weighing approximately 500 kg, submitted to race proved short distance (300 meters). Serum aspartate aminotransferase values were measured (AST), creatine kinase (CK), lactate and glucose 15 minutes before and 15 minutes after exercise. When comparing the results using T-Student (p < 0.05), it was observed that there is a statistically significant difference when comparing the groups, it is possible to notice wear and muscle regeneration, as well as adaptation to exercise. Serum tests have demonstrated good sensitivity to monitor the physical condition of the animals before and after undergoing the short run test.
Highlights
As análises laboratoriais de níveis bioquímicos séricos são imprescindíveis para realizar a avaliação do equino que esteja participando de uma competição
A avaliação da AST deve ser associada aos valores séricos de creatine kinase (CK), para a avaliação dos efeitos do exercício proposto aos equinos e as alterações musculares (Câmara-Silva; Dias; Soto-Blanco, 2007)
O lactato sérico foi a alteração de maior significância quando comparado os animais antes após a prova de corrida
Summary
As análises laboratoriais de níveis bioquímicos séricos são imprescindíveis para realizar a avaliação do equino que esteja participando de uma competição. A enzima aspartato aminotransferase (AST) e a lactato desidrogenase (LDH) são enzimas com atividade nos hepatócitos e fibras musculares e têm sido utilizadas associadas à creatinoquinase (CK) para a avaliação das lesões musculares, entre elas, as provocadas pelo exercício (Franciscato et al, 2006).
