Resumo
Os programas de treino devem melhorar o condicionamento físico dos cavalos de desporto e, ao mesmo tempo, preservar o seu bem-estar. As guias mecânicas são amplamente utilizadas no maneio e no treino, pois permitem que vários cavalos sejam exercitados simultaneamente de forma controlada. Assim, o objetivo desta pesquisa foi avaliar a eficácia de um programa de treino de sete semanas, com recurso a uma guia mecânica para cavalos de salto de obstáculos. Deste modo, quatro cavalos treinados, com ~14 anos de idade, ~582,3 kg, foram avaliados antes e depois de um protocolo de treino que incluía o uso da guia mecânica (durante 1h, duas vezes/semana, em velocidades semanais crescentes, começando em 1,7 km/h em S1 e terminando em 7 km/h em S7) e uma determinada sequência pré-estabelecida de exercícios durante 7 semanas. Foi considerado que os animais observados constituíam o seu próprio grupo de controlo, uma vez que já realizavam estes exercícios há mais de 6 meses. Em ambas as ocasiões os animais foram avaliados através de testes a campo de salto de obstáculos, nos tempos antes e logo após a atividade física, com 30 min e 240 min de recuperação, quando foram registadas frequência cardíaca, frequência respiratória, temperatura corporal, contagem total de células sanguíneas, lactato e glicose sanguínea, proteínas séricas, albumina, AST e CK. Durante o exercício os animais utilizaram um monitor de FC (Polar H10). Os dados foram analisados pelos testes Tukey e teste-t de Student (p<0,05). Valores mais elevados de CHCM e valores mais baixos de VCM, cortisol, contagem total de leucócitos e contagem de neutrófilos foram observados após o período de treino. Apesar do número limitado de cavalos, o protocolo proposto manteve o condicionamento físico pré-existente e possivelmente melhorou o bem-estar psicológico, uma vez que os níveis de cortisol desceram após o treino.

Training programs must improve the physical conditioning of athletic horses, while simultaneously preserve their well-being. Horse walkers are used extensively in both the management and training, allowing multiple horses to be exercised simultaneously in a controlled fashion. Therefore, the aim of this research was to evaluate the effectiveness of a seven-week training program, using an automated horse walker for jumping horses. Four trained horses, ~14 years-old, ~582.3 kg, were evaluated before and after a training protocol that included the horse walker (for 1h, twice/week, at weekly increasing speeds, starting at 1.7 km/h in S1 and ending at 7 km/h at S7) plus a well-known sequence of exercises for 7 weeks. Animals acted as their own control group as they have been performing these exercises for more than 6 months. On both occasions animals were examined through a jumping field test, before and after the exercise and at 30 min and 240 min of recovery, where heart rate, respiratory rate, body temperature, total blood cell count, blood lactate and glucose, serum proteins, albumin, AST and CK were determined. During the exercise animals used a HR monitor (Polar H10). Data was analysed using Tukey and Student t-test (p<0.05). Higher values of MCHC and lower values for MCV, cortisol, total WBC count and neutrophils count were observed after the training period. Although the limited number of horses, the proposed protocol maintained the pre-existing physical conditioning while possibly improving the psychological well-being, as cortisol levels dropped after the training.
