Resumo
O presente estudo investigou o recrutamento muscular em equinos de saltos de obstáculos submetidos a um treino complementar na passadeira aquática. Seis equinos, em nível moderado de competição, e clinicamente aptos foram avaliados antes (PRETR) e 10 semanas após (TR) a implementação de um protocolo de treino na passadeira aquática (duas vezes por semana, 20 minutos, água ao nível do carpo), além de atividades físicas regulares, respeitando os limites individuais de cada animal. Em ambos os momentos, os animais foram sujeitos a termografia dos músculos braquiocefálico, semitendinoso e semimembranoso, medição da gordura da garupa por ecografia, e testes de campo de saltos de obstáculos para análise de creatina quinase (CK) e aspartato aminotransferase (AST). Adicionalmente, colheitas sanguíneas foram realizadas durante as semanas 2, 4, 6 e 8 do treino na passadeira aquática para avaliação de CK. Os dados foram analisados pela ANOVA, teste de Tukey e teste-t, considerando p?0,05. Os resultados demonstraram aumento significativo de temperatura na termografia dos músculos estudados e ativação de AST e CK após as 10 semanas de treino. Além disso, a CK aumentou significativamente de forma progressiva a cada duas semanas, verificou-se também ganho de massa magra muscular. Tais resultados sugerem que o treino proposto promoveu o recrutamento muscular e contribuiu, de forma significativa, para a melhoria da aptidão desportiva dos equinos em provas de saltos de obstáculos.

The aim of this study was to investigate muscle recruitment in jump sport horses after a complementary water treadmill training. Six horses, at a moderate competition level and clinically fitted, were evaluated before (PRETR) and 10 weeks after (TR) the implementation of a water treadmill training protocol (twice a week, 20 minutes, water at the level of the carpus), in addition to regular physical exercise, respecting the individual limits of each. At both times, the animals were subjected to thermography of the brachiocephalic, semitendinosus, and semimembranosus muscles, measurement of rump fat by ultrasound, and show jumping field tests for the analysis of creatine kinase (CK) and aspartate aminotransferase (AST). Additionally, blood samples were taken during weeks 2, 4, 6 and 8 of the water treadmill training to evaluate CK. Data were analysed using ANOVA, Tukey test and t-test, considering p≤0.05. The results showed a significant increase in temperature in the thermography of the muscles under study and activation of AST and CK after the 10-week training protocol. Furthermore, CK also increased progressively every two weeks, and there was an increase in lean muscle mass. These results suggest that the proposed training has promoted muscular recruitment and has also contributed to the enhancement of the sporting fitness of horses used in show jumping competitions. Keywords: performance, exercise, water treadmill, CK, muscle thermography
