“…By contrast, endurance-trained horses have lower resting RBC, PCV and HB than sprinttrained horses Robert et al, 2010;Trigo et al, 2010). In fact, in our experience, is very common to find PCV as low as 30-32% in endurance healthy horses with good performance .…”

“…There are two main reasons to explain these results. Firstly, it has been indicated that feeding fibrous diets might increase water consumption and then plasma volume (Robert et al, 2010). The second reason is the effect of a greater release of aldosterone, which promotes water and electrolyte-conserving mechanisms in the kidneys and gastrointestinal tract (McKeever et al, 2002).…”

“…As published by Robert et al (2010), studies on endurance and prolonged exercising horses often report only descriptive results, and physiological explanation of changes responsible for the observed alterations is rarely provided. It is probably due to the alterations of plasma volume which vary in horses subjected to the different physical performance on a variety of environmental conditions, as reviewed by Carlson (1987).…”

The aims of this study were to analyze the indices of mineral, enzymatic, protein and lipid metabolism, and the antioxidant status in horses trained for jumping after prolonged exercise. A total of 10 Slovak warmblood horses (aged 6-15 years) trained for jumping were used. Blood samples were taken before and after the jumping training (control), immediately after prolonged exercise and after the following 36 h of rest. Control samplings showed no signs of exerciseinduced dehydration, but an increase of haematological indices, increased concentration of lactate and increased activity of lactate dehydrogenase whose changes may be indicative of splenic blood efflux and activation of anaerobic metabolism. On the other hand, changes of biochemical indices (such as: increased alanine aminotrasferase, lactate dehydrogenase and creatine phosphokinase, decreased K and Fe, increased malondialdehyde and glutathione peroxidase) that are indicative for the muscle membrane leakage, oxidative stress and electrolyte imbalances, and alterations of intermediary metabolism were found due to the non-standard prolonged exercise. Although this study demonstrates that trained horses adapted to a certain exercise regimen are exposed to oxidative and metabolic stress by non-standard prolonged workload, further research is required to assign an appropriate resting regime needed to compensate for the induced biochemical changes. Equine, metabolic indices, antioxidants, performanceAs published by Robert et al. (2010), studies on endurance and prolonged exercising horses often report only descriptive results, and physiological explanation of changes responsible for the observed alterations is rarely provided. It is probably due to the alterations of plasma volume which vary in horses subjected to the different physical performance on a variety of environmental conditions, as reviewed by Carlson (1987). Hypovolaemia caused by exercise-induced dehydration is a problem to which mostly endurance and prolonged exercising horses must respond.It is well known that during prolonged exercise in horses, loss of water and electrolyte via sweat may develop exhaustion with hypovolaemia and electrolyte changes, which subsequently result in fatigue, metabolic disturbances, fractures and even death. For example, positive correlation between exercise intensity and gastric ulceration severity was proven by Bezdekova et al. (2005). Physiologically speaking, correct interpretation of the metabolic changes after prolonged or endurance exercise in horses is required, because it can help the veterinarian, trainer, or owner to choose appropriate training and post-exercise recovery as well as adequate dietary supplementation.The aim of this study was to determine the influence of a non-standard prolonged exercise in horses trained for jumping on chosen haematological and biochemical indices which are related to mineral, enzymatic, protein and lipid metabolism and to the antioxidant status.

“…The decrease was also observed in horses finalists in 120 km-competitions (Robert et al, 2010;Viu et al, 2010). When associating the value found for the chloride ion with pH, it was possible to observe that the initial changes would induce hypochloremic metabolic alkalosis, if the animals continued the route, and showed complications in exhaustion syndrome.…”

“…A diminuição também foi observada em equinos finalistas em competições de 120km (Robert et al 2010, Viu et al 2010. Sobretudo, quando associado o valor encontrado para o íon cloro juntamente com o pH, foi possível entender que as alterações iniciais estariam induzindo alcalose metabólica hipoclorêmica, caso os animais continuassem o percurso, e ainda complicações relevantes na síndrome de exaustão.…”

Dumont, Cinthia Beatriz da Silva A INFLUÊNCIA DA DISTÂNCIA NA DESCLASSIFICAÇÃO DE EQUINOS DE ENDURO -ALTERAÇÕES HIDROELETROLÍTICAS, HEMOGASOMÉTRICAS E BIOQUÍMICAS/ Cinthia Beatriz da Silva Dumont AGRADECIMENTOSAgradeço primeiramente a Deus e a espiritualidade maior pela ajuda em me fazer compreender e lidar com todas as situações de dificuldades durante não só na esfera profissional e acadêmica, mas também da vida cotidiana.Aos meus pais e avós pelo amor maior. Amo vocês, SAUDADES!!!!!! Meus mais sinceros agradecimentos ao meu orientador, Prof. Dr. Eduardo MaurícioMendes de Lima por mais essa oportunidade, pela confiança, pela paciência sem tamanho, pelas conversas, broncas e conselhos, pela orientação e amizade e por ter se tornado meu grande amigo. E também, minhas desculpas mais sinceras se deixei a desejar!!!!Ao amigo e chefe da equipe veterinária Meryonne Moreira, presente na minha formação profissional desde a época de estágios, pelo profissionalismo, competência e por permitir o trabalho durante a realização das provas.Aos amigos, Júlia Moraes, Ceci Ribeiro, Mariana Damázio e aqueles que foram fundamentais no trabalho de campo, durante a fase de colheita de material.Às equipes, tratadores e responsáveis pelos animais e a todos os enduristas que participaram deste estudo, pela cooperação, paciência, apoio, e parceria demonstrada nos momentos de colheitas. Às equipes do Medicalvet Laboratório Veterinário, na pessoa de RicardoSampaio e do Santé Laboratório, na pessoa de Gláucia Balsamão, que colocaram sua equipe à disposição para realização das análises mesmo fora do horário de expediente.Aos queridos colegas André Viana, Fabieni Okiama, Kaique Nogueira e Anna Eris, que foram incansáveis e fundamentais para a confecção, o término e a qualidade desse trabalho.Aos maravilhosos cavalos atletas, objeto de estudo desta pesquisa. Eles são a razão de tudo, devem ser respeitados e amados!!! ABSTRACTWe evaluated 18 horses that were disqualified from endurance race championships exclusively due to metabolic changes. The athlete horses were examined immediately after they had completed the 30, 40, 60, 72, 90 or 140 km races, before there was any clinical and therapeutic intervention for animal recovery. In the first experiment, the horses completed the 30, 60 or 90km races and the following parameters were measured immediately after: hematocrit levels, total plasma proteins (TPP), anion gap, base excess/deficit, osmolarity, pH, and the concentrations of hydrogen ions, bicarbonate, sodium, potassium, calcium and chlorine. In the second experiment, the horses comp...
