Resumo
A avaliação da condição física relativamente a todas as disciplinas equestres tem vindo a ganhar uma importância crescente. Os testes de simulação de campo podem ajudar a determinar o nível de aptidão de cavalos atletas e as suas condições de bem-estar durante o período de treino. Dada a escassez de estudos em cavalos de trabalho com toiros bravos, este estudo teve como objetivo examinar as alterações de biomarcadores num teste de campo, efetuado com cavalos PSL (Puro Sangue Lusitano). Para este propósito, 5 cavalos treinados, com ~9,8 anos de idade, foram examinados através de um teste de simulação a campo (TSL), onde o exame físico (frequência cardíaca-FC; frequência respiratória-FR; temperatura corporal-BT) e amostras de sangue foram obtidos antes e sequencialmente após o exercício. Foram determinados hemograma completo, lactato, glicose, AST e CK. Os dados foram analisados usando ANOVA para medições repetidas e teste de Tukey (p < 0,05). O teste de exercício alterou significativamente alguns dos parâmetros fisiológicos estudados (FC, FR, BT, lactato, contagem de hemácias, PCV e concentração de hemoglobina), com valores mais elevados registados imediatamente após o esforço. A partir de 30 minutos de recuperação, houve retorno aos valores basais. Os cavalos trabalharam a uma velocidade média de 3,8 m/s, com uma FC de ~99 batimentos/min. Foi possível concluir que o teste de simulação proposto levou a modificações significativas dos biomarcadores dos equinos estudados, compatíveis com o nível de esforço imposto. Os animais apresentaram bom condicionamento físico, visto o rápido retorno aos valores basais. Tais dados podem orientar a avaliação a campo de atletas equinos utilizados nesta disciplina equina específica, visando melhorias de performance desportiva e de práticas de bem-estar animal.
The physical condition assessment in all equestrian disciplines has been gaining increasing importance. Field simulation tests can help determine the fitness level of athletic horses and their well-being conditions during the training period. Given the lack of studies on bull-running horses, this study aimed to study biomarker changes in a field test conducted with Lusitano Purebred horses (PSL). For this purpose, 5 trained horses, ~9.8 years old, were examined through a simulation field test (SFT), when physical examination (heart rate-HR; respiratory rate-RR; body temperature-BT) and blood samples were obtained before and sequentially after exercise. CBC, lactate, glucose, AST, and CK were determined. Data was analysed using ANOVA for repeated measurements and Tukey's test (p<0.05). The exercise testing significantly altered some of the studied physiological parameters (HR, RR, BT, lactate, RBC count, PCV, and hemoglobin concentration), with higher values recorded immediately after the effort. After 30 minutes of recovery, there was a return to baseline values. The horses worked at an average speed of 3.8 m/s, with a HR of ~99 beats/min. It was possible to conclude that the proposed simulation test led to significant changes in the biomarkers of the studied horses, compatible with the level of effort imposed. The animals presented good physical conditioning, given the rapid return to baseline values. Such data can guide the field evaluation of equine athletes used in this specific equine discipline, aiming at improving sports performance and animal welfare practices.
