O trabalho teve como objetivo verificar o efeito da adi o de 車leo de soja e do treinamento na atividade plasm芍tica das enzimas Creatina Quinase (CK) e Aspartato Aminotransferase (AST) sobre o trabalho muscular de equinos submetidos a teste de resist那ncia. Foram fornecidas dietas experimentais compostas por cinco n赤veis de 車leo desoja no concentrado (controle, 6, 12, 18 e 24%). Foram utilizados 20 equinos da ra a 芍rabe, peso m谷dio de 400 kg, submetidos a teste de resist那ncia de 80 km em esteira rolante, em Laborat車rio de Fisiologia do Exerc赤cio. A simula o de enduro foi dividida em quatro fasesde 20 km cada. Observou-se efeito (p %26lt; 0,05) da adi o de 車leo e da distancia percorrida sobre as vari芍veis AST e CK durante o enduro e tamb谷m no per赤odo de recupera o. Conclui-se que o 車leo atua de forma ben谷fica sobre o trabalho muscular por diminuir a atividade das enzimas AST e CK em n赤veis superiores a 6% de 車leo no concentrado. Apresen a de elevados valores de atividade enzim芍tica n o est芍 obrigatoriamente ligada 角 presen a de enfermidades musculares. Cada animal deve ser analisado individualmente, tendo como base a sua atividade enzim芍tica basal. The aim of this study was to verify the effect of increasing soybean oil levels and training on the enzyme activity of AspartateAminotransferase (AST) and Creatine kinase (CK) as indicative of muscle work. Experimental diets were composed by five soy oil levels in the concentrate (control- no oil, 6, 12, 18 and 24%). Twenty Arabian horses, male and female, average weight of 400 kg weresubmitted to an 80-km endurance race in a treadmill. The treadmill experiment was conducted in the Exercise Physiology Laboratory. The endurance simulation was divided in 4 phases of 20 km each. The effect (p %26lt; 0.05) of soybean oil addition and run distance forCK and AST variables during the effort test and also in the recovering time were observed. It was concluded that soybean oil presents a beneficial effect on muscle work, as it decreasesthe activity of AST and CK enzymes in diets with more of 6% of soybean oil in the concentrate. The elevated value showed was not necessarily linked to muscle pathology presence. Each animal must be analyzed individually, based on its corresponding basal enzymatic activity.
