“…Thus, the reference limits obtained by them in RBC, Hb, Hc and LDH (Muñ oz et al, 2012) were lower in their upper limit than those observed in this study (Muñ oz et al, 2012). Similarly, RBC, Hb and Hc reference values, were higher than the normal values shown by other authors for untrained SPBs (Escribano et al, 1995;Rubio et al, 1995 and1996;Satue et al, 2009). However, with the exception of the reference value for the Hc, all the haematological and biochemical parameters studied were inside the reference limits described by Muñ oz et al (2012) for the adult SPB.…”

“…Up until now, in the SPB, variations with exercise had only been observed in field, for haematological and biochemical parameters, aerobic capacity and fitness, muscle fibre type characteristics and normal kinematic patterns (Ló pez Rivero et al, 1989;Escribano et al, 1995;Rubio et al, 1995). Only the biokinematic variables had been standardized under treadmill conditions in a numerous group of horses (Cano et al, 2000).…”

The novel aim of this study was to describe the reference values of different haematological and biochemical parameters in the Spanish purebred horse (Andalusian, SPB) in each of the stages of a programmed exercise on a treadmill system, and to establish heritability and genetic correlations for these haematological and biochemical parameters. For this, 94 young SPB male horses (4.22 6 2.27 years old) were used. An increasing intensity exercise test at 4, 5, 6 and 7 m/s was carried out on a treadmill (6% inclination). Total red blood cells, total white blood cells, neutrophils and lymphocytes counts; haematocrit, haemoglobin, lactate, uric acid, creatinine and total plasma proteins concentrations and aspartate transaminase, lactate dehydrogenase, creatine-quinase activities were determined. To conclude: (i) the reference values for each parameter were determined for each of the exercise test stages (ii) all the parameters analysed manifested a medium-high heritability and a high repeatability. These results will, in the near future, determine the measuring guidelines for improving the SPB horse's athletic ability on an objective treadmill system and for selecting these animals in response to those parameters.

“…However, the previous results were presented for Standardbred racehorses, and the age at which an Andalusian horse can be considered physiologically matured is unknown. Although some interbreed comparative studies between foals and adults Andalusian, Anglo-Arabian and Arabian horses have been made (Castejón et al 1994;Rubio et al 1995), no research exists regarding foals and adult Andalusian horses.…”

The main objective of this study was to analyse the relationship between the slope of the plasma lactate accumulation in response to exercise and working capacity in two groups of Andalusian horses of different age.The horses were subjected to increasing intensity tests, comprising both submaximal and maximal velocities. Heart rate was monitored throughout the exercise and jugular venous blood samples were withdrawn at rest, after each workload and during the first 30 min. of recuperation. Working capacity was assessed by means of these functional indices: HRmax (maximum mean heart rate during exercise), Vmax (maximum velocity), STEPmax (maximum number of workload completed), VLA2 (aerobic threshold), VLA4 (anaerobic threshold), PLA (lactate peak), pHmin (minimum pH) and PCVmax (maximum packed cell volume).HRmax, pHmin, VLA2, VLA4, STEPmax and Vmax were positively correlated with working capacity, whereas PLA and PCVmax were negatively correlated with working capacity. The slope of the plasma lactate accumulation curve were inversely related to VLA2, VLA4, Vmax, STEPmax and pHmin and positively related to HRmax and PCVmax. Besides, the plasma lactate slope was higher in the youngest Andalusian horses.These results indicated that the slope of the plasma lactate concentrations after several exercise intensities might be considered as a marker of aerobic potential, providing useful information about fitness and training degrees in the Andalusian horse. Exercise, fitness, heart rate, packed cell volumePhysical exercise requires a balance between production and consumption of energy within working muscles. It has been postulated that there is a critical intensity or threshold above which the cardiovascular, respiratory and/or muscular responses are of insufficient magnitude to supply energy through aerobic pathways. As a consequence, anaerobic pathways become predominant, and large amounts of lactate (LA) are produced. LA is considered to be a small and easily diffusable anion, and it may be translocated rapidly between the water compartments of the body. Muscle LA produced during exercise can be utilised by the active muscles, exported via the blood to other organs, principally liver and heart, or taken up by other muscles with adequate oxygen supply and utilised as a source of fuel (Brooks 1986;Marlin et al. 1987).Three different models of plasma LA accumulation have been proposed. The single breakaway point is the classical model of aerobic-anaerobic transition. M a r g a r i a et al. (1933) established that lactic acid was formed and plasma LA accumulated during times of local muscle hypoxia, such as the onset of exercise and during times of oxygen deficit.

“…Essa modiϐi-cação poderia ser explicada pela contração esplênica, como foi observado por Ferraz et al (2010) em equinos durante competições de pólo, ou pela desidratação, entretanto, as perdas substanciais de ϐluidos durante este tipo de atividade teriam maior inϐluência na elevação do Hct em função da redução do volume plasmático (Kingston 2004). Os animais avaliados mantiveram-se com valores de Hct próxi-mos aos ϐisiológicos (43±4%) conforme Rubio et al (1995) para animais PSA acima de 4 anos, sugerindo portanto a ocorrência de um processo de desidratação leve sem interferências no desempenho.…”

Osmolaridade, ânion gap, potencial hidrogeniônico e íons plasmáticos mensuráveis de equinos puro sangue Árabe finalistas em provas de enduro de 90 km

Foi avaliado o comportamento da osmolaridade, do ânion gap, do pH e dos íons plasmáticos mensuráveis de 14 equinos, 9 machos e 5 fêmeas, Puro Sangue Árabe finalistas em provas de enduro de 90 km. Para tanto, foram colhidas em dois momentos (repouso e após o exercício prolongado) amostras de sangue venoso para a mensuração dessas variáveis. Pode-se verificar, a partir do repouso, aumento significativo dos valores do Hct, das PPT e do AG, sugerindo perda de fluidos e discreto grau de desidratação. O pH e o íon H+ quase não se alteraram, indicando ausência de distúrbios metabólicos. Reduções com diferenças significativas foram observadas para os íons Cl-, HCO3-, K+, Ca++, assim como do EB. Pode-se então, sugerir que o tipo de exercício a que os animais foram submetidos foi compatível com a capacidade atlética e ainda que a suplementação durante a competição contribuísse para minimizar tais perdas.
