Resumo
O presente estudo avaliou o custo de transporte (COT) durante o exercício e a potência (P) de cavalos sem condicionamento físico antes e depois de serem adaptados à esteira rolante. Estas variáveis também foram avaliadas antes e depois de um período de seis semanas de treinamento. Treze equinos, da raça Puro Sangue Árabe, de aproximadamente 24 meses, foram submetidos ao teste de adaptação em esteira e, posteriormente a uma semana de adaptação, ao teste de estresse. Após o término do período de treinamento de seis semanas, os animais realizaram novamente um teste de estresse. Antes de iniciar cada teste, os cavalos foram equipados com monitor de frequência cardíaca RS800CX GS Equino Pollar para os registros de frequência cardíaca. Os eletrodos foram fixados na porção ventral do tórax sobre a pele, na altura do choque precordial, sob uma cinta larga de couro passada ao redor do tórax, pela qual foi preso o sistema de segurança da esteira rolante. Os dados dos últimos 2,5 minutos dos testes foram utilizados. Utilizou-se um computador pessoal com software Polar ProTreiner Equine Edition para determinar os valores médios da FC basal e durante exercício. Para cálculo das fórmulas de COT e P, foi feita a média do peso vivo dos animais e junção dos dados de distância do exercício em metros, duração do exercício em minutos e velocidade do exercício em metros por segundo. Os valores foram baixados em software R© e analisados pelo Teste T Student (P<0,05). Quando a natureza dos dados não permitiu a utilização de teste paramétrico, foi utilizado o teste não paramétrico de Wilcoxon. Foi encontrada diferença estatística no valor de COT entre o teste de adaptação (TA) e o teste de estresse 1 (TE1), podendo concluir que, o fato de os animais não serem condicionados ao exercício e não adaptados à esteira, interferiu nos dados, já que a agitação e estresse levam à alteração da FC e, consequentemente, das outras variáveis, e que, apesar da interferência, a adaptação dos animais ao método de exercício à esteira rolante mostrou relação direta com o COT, já que, apesar de aumentar a velocidade, o COT foi menor no TE1, no qual os animais já estavam mais adaptados à esteira. Também se concluiu que um período de seis semanas de treinamento é capaz de melhorar o condicionamento físico dos animais, reduzindo o COT e a P.
The present study evaluated the transport cost (COT) during exercise, and the power (P) of unconditioned horses before and after being adapted to the treadmill. These variables were also evaluated before and after a six-week training period. Thirteen Purebred Arabian horses, approximately 24 months old, were submitted to the adaptation test on a treadmill and, after a week of adaptation, to the stress test. After the end of the six-week training period, the animals underwent a stress test again. Before starting each test, the horses were equipped with a heart rate monitor RS800CX GS Equine Pollar to record the heart rate (HR). The electrodes were attached to the ventral portion of the thorax, on the skin at the level of the precordial impact, under a wide leather strap passed around the thorax, by which the security system of the treadmill was attached. Data from the last 2.5 minutes of the tests were used. A personal computer with Polar ProTreiner Equine Edition software was used to determine mean baseline and exercise HR values. To calculate the COT and P formulas, the average live weight of the animals was calculated and data on the exercise distance in meters, exercise duration in minutes and exercise speed in meters per second were combined. The values were downloaded into R© software and analyzed using the Student T Test (P<0.05). When the nature of the data did not allow the use of a parametric test, the non-parametric Wilcoxon test was used. A statistical difference was found in the COT value between the adaptation test (TA) and the stress test 1 (TE1), leading to the conclusion that the fact that the animals were not conditioned to exercise and were not adapted to the treadmill interfered in the data, since ingestion and stress lead to changes in HR and, consequently, in other variables, and that, despite the interference, the animals' adaptation to treadmill exercise showed a direct relationship with COT, since, despite increasing speed , the COT was lower in TE1, in which the animals were already more adapted to the treadmill. It was also concluded that a period of six weeks of training can improve the physical training of the animals, the COT and P.
