“…Previous studies found similar results in 30 km endurance rides with controlled effort (Fernandes & Larsson 2000). They afϐirmed that creatinine elevation during prolonged exercise occurs due to altered renal function (leading to glomerular ϐiltra-tion rate decrease), which are associated with important ϐluid losses that happen during this type of exercise.…”

Pesq. Vet. Bras. 32(9) The aim of this study was to evaluate the behavior of blood constituents in a group of horses that successfully completed long endurance rides in tropical conditions. Jugular vein puncture was done to collect blood before, during and after rides. Data were analyzed using a mathematic approach, based on the hematocrit and blood volume where the percentual change in plasma volume was used to correct the values of each variable analyzed. Signiϐicance was inferred when P<0.05. The proposed mathematical model to assess blood constituents concentrations allowed the observation of a different pattern of the variables behavior, pointing out that the approach followed by the authors could be more sensitive than ones that did not take this routine. In conclusion, the method used in this study enabled to monitor the physiological processes that actually occur during endurance effort in tropical conditions.

RESUMO.-[Avaliação metabólica de cavalos Crioulos submetidos a uma competição de resistência de 750 km.] O cavalo Crioulo realiza uma das provas de maior exigência física nas modalidades equestres. A Marcha de Resistência é uma competição na qual os animais percorrem 750km durante 15 dias. O objetivo desse estudo foi caracterizar as respostas metabólicas ocorridas nesse período. Foram avaliados 11 equinos da raça Crioula inscritos na competição, sendo dois machos e nove fêmeas. Foram efetuadas coletas de sangue 24h antes da prova e no 4º, 9º, 11º, 14º e 15º dia de competição. Foram avaliados a concentração sanguínea de creatininoquinase, aspartato aminotransferase, lactato desidrogenase, glicose, lactato, uréia, creatinina, sódio, potássio, cloreto, magnésio, cálcio total, cálcio iônico, proteínas totais, hematócrito e o leucograma. Ao final da competição os valores médios de AST sérica foram de 1151±358 UI/L, os valores de médios de LDH foram de 7418±1695 UI/L e de CK foi de 13867±3998UI/L. Houve aumento significativo nos valores de uréia, creatinina e lactato (p<0,0001). Foi observada diminuição nos valores médios de cloreto, sódio, potássio, cálcio total e iônico (p≤0,0002). Na avaliação hematológica foi constatada elevação nos valores de leucócitos totais e segmentados (p≤0,0002) e diminuição nos valores de hematócrito, proteína plasmática total e linfócitos (p≤0,0003 The Crioulo breed of horses performs in one of the most physically demanding equestrian competitions, the Marcha de Resistência, which is a contest in which the horses run 750 km in 15 days. The study's aim was to characterize the metabolic responses during this period. We evaluated eleven Crioulo horses in the competition, specifically, two males and nine females. Blood samples were collected 24 hours before the contest and on the 4 th , 9 th , 11 th , 14 th and 15 th days of competition. We evaluated CK, AST, LDH, glucose, lactate, urea, creatinine, sodium, potassium, chloride, magnesium, total calcium, ionized calcium, total protein, hematocrit and the white blood cell count. At the end of the competition, the mean values of serum AST were 1151±358 IU/ L the mean LDH values were 7418±1695 IU/L and CK was 13,867±3998UI /L. There was a significant increase in urea, creatinine and lactate (p<0.0001). A decrease in the mean values of chloride, sodium, potassium, and total and ionized calcium was observed (p≤0.0002). An evaluation of the total leukocytes and segmented neutrophils (p≤0.0002) revealed their increased values, and decreased values were observed for hematocrit, plasma protein and total lymphocytes (p≤0.0003). The values of glucose, on average, remained constant. Based on these data, we conclude that the Marcha de Resistência competition necessitated a high muscular demand and the depletion of energy and electrolytes, suggesting an inflammatory process in the animals evaluated.
