“…Este valor foi inferior ao descrito no presente estudo, onde detectaram-se valores de 9,86±2,09mmol/L no pós-exercício imediato. Por se tratarem de pesquisas que submeteram os equinos a um nível de esforço físico semelhante, esta disparidade de valores pode ser atribuí-da ao momento da coleta, visto que no trabalho de Marques (2002) as amostras de sangue foram obtidas 30 minutos após o término da atividade física e na presente pesquisa a amostras foram coletadas imediatamente após o término da mesma, conforme recomenda Keadle et al (1993), que citam que o pico de lactato plasmático ocorre em até 10 minutos após o exercício.…”

452Pesq. Vet. Bras. 31(5): 452-458, maio 2011 RESUMO.-O presente estudo teve por objetivo avaliar a influência do exercício físico de alta intensidade e curta duração (provas de laço em dupla) sobre a lactacidemia e as concentrações séricas de aspartato aminotransferase (AST) e creatinoquinase (CK) em equinos durante competição realizada no estado do Espírito Santo. Para tal foram obtidas amostras de soro e plasma de 20 equinos, da raça Quarto de Milha ou mestiços, em três momentos assim definidos: no repouso, uma semana antes da prova atlética, já com o animal em treinamento (T0); antes da prova atléti-ca (T1) e imediatamente após o término da mesma (T2). As referidas amostras foram encaminhadas ao Laboratório Clí-nico do Centro Universitário Vila Velha (UVV) para as análi-ses. Na avaliação da lactacidemia, os resultados registrados nos momentos T0, T1 e T2 foram, respectivamente, de 0,49±0,24mmol/L, 0,93±0,16mmol/L e 9,86±2,09mmol/L. Na avaliação da atividade sérica de AST, os resultados registrados nos momentos T0, T1e T2 foram, respectiva- The aim of the present study was to evaluate the effects of high intensity and short duration physical exercise (roping team competition) on plasma lactate and serum AST and CK concentrations in horses during competition at Espírito Santo state, Brazil. Blood samples were obtained from 20 Quarter Horses, or cross-bred, in three moments: (1) at rest, one week before the competition, with the animals being trained, (2) just before the competition, and (3) immediately after the exercise. The samples were sent to Laboratório Clínico do Centro Universitário Vila Velha for analysis. Plasma lactate concentrations were 0.49±0.24mmol/L, 0.93±0.16mmol/L e 9.86±2.09mmol/L, respectively, on the moments rest and immediately before and after the exercise. Serum concentrations of AST were 189.1±43.6 IU/L, 210.2±46.7 IU/L e 173.1±33.5 IU/L, respectively, on the moments rest and immediately before and after the exercise. Finally, serum concentrations of CK were 110.9±35.2 IU/L, 51.8±15.4 IU/L and 88.2±33.5 IU/L, respectively, on the moments rest and immediately before and after the exercise. Results showed that the imposed physical exercise leaded to a significant elevation of plasma lactate and serum CK without alteration on AST. It was possible to conclude that horses were adapted to the level of exercise performed.

“…It has also been demonstrated that cortisol concentration significantly increases as a response to acute exercise in horses (Wilson et al 1991;Keadle et al 1993;Horohov et al 1999;Marc et al 2000). Cortisol is another hormone whose release is triggered by innate stress and other normal physiological challenges such as exercise.…”

“…Previous studies have investigated the effects of exercise on plasma 0-endorphin and cortisol concentrations in horses (McCarthy et al 1991;Mehl et al 1999;Keadle et al 1993); however, only one report has demonstrated an age effect (Horohov et al 1999). The interrelationships among exercise, training, hormone production and immune function have been addressed by several studies in man as well as rodents (reviewed in Pedersen and Hoffman-Goetz 2000); however, similar examinations of equine athletes have not been published.…”

“…Studies of adaptive immunity are less frequent and related to lymphocyte proliferation after specific or non-specific stimulation, and the dosage of cytokines, as well as to the production of antibody. 9,19,21 The observations reported in the horses are rather similar to those observed in humans: namely • an intense -or prolonged -effort is associated with an early neutrophil burst (and leukocytes in general); secretion of pro-inflammatory cytokines during exercise and augmentation of LAK activity [22][23][24] • a later impairment of the innate immunity during the recovery period. 10,16,25,26,27,28 …”
