“…This finding may be related to the fact that the heavier animals may not necessarily represent the best cardiac performance, as is the case of the Puro Sangue Inglês group, which in the study were the heaviest animals, and presented a physical performance below expectations. (Bonomo et al, 2014;Hinchcliff et al, 2008).…”

“…Regarding the ventricular septum, greater thickness was observed in animals 2 and 5, it is important to note that both had an active athletic life. According to Bonomo et al (2014) physical training that requires resistance and strength, allows the establishment of eccentric and concentric hypertrophy. In this case, he studied PSI and Quarter Mile animals, which showed a better response of cardiac function at rest.…”

The present work has as main objective to analyze the equine cardiac ventricles after death, from the morphoquantitative measurement. Six hearts of different races of horses with the presence or absence of different sports skills were used. The hearts were collected after the animal died and the cause of death was not stated. Six hearts of the equine species were analyzed, being 50% males and 50% females. As for the breed 33.3% was Quarter mile, 33.3% was Machador Broad Sleeve and 16.6% was Paulista Broad Sleeve and 16.6% was PSI. About athletic life, 50% were considered equine and the average weight of the animals was 426.83 kg, with the lowest weight 295 kg and the highest 560.0 kg. Regarding the dimensions of the hearts analyzed, the average weight of the ventricles was 2.71 kg, with the lowest weight 1.63 kg and the highest weight 3.83 kg; On the size of the base, it found an average of 22.28 cm, with the base smaller 17.0 cm and the largest base 25; As for the axis, the average was 25.66 cm, being the smallest of 22.0 cm and the largest of 30. Regarding the number of slices, case 1 was the smallest, being 9 and Case 2 and 5 presented a larger number of slices, being 12. Physical activity in horses seems to be associated with myocardial hypertrophy and this fact may increase the axis and allow greater cuts and action analysis.

“…Esta diferença entre as dimensões das estruturas cardíacas, entre os grupos de diferentes faixas etárias, pode ser explicada como resultados do crescimento fisiológico normal ou ainda devido a uma resposta fisiológica frente ao trabalho o qual são normalmente submetidos (Young 1999, Buhl et al 2004, Bonomo 2014, porém este estudo não nos permite concluir a causa de tal alteração, visto que a atividade física não foi item de avaliação neste trabalho.…”

Resumo: Com o objetivo de determinar os valores de referência ecocardiográficos de equinos da raça Mangalarga Marchador, foram avaliados 80 equinos desta raça, machos e fêmeas, com 1,6 a 16 anos de idade, pesando entre 320 a 500 kg, divididos igualmente em 4 grupos: fêmeas de 1,6 a 4 anos de idade (G1), fêmeas com mais de 4 anos de idade (G2), machos de 1,6 a 4 anos de idade (G3), machos com mais de 4 anos de idade (G4). A avaliação constou de exame ecocardiográfico mono e bidimensional, tendo sido realizados através da janela cardíaca direita, nos modos B e M: DIVDs, DIVDd, SIVs, SIVd, DIVEs, DIVEd, PLVEs, PLVEd, Aod, FS%, EF%, AEs, Aod, Aes/ Aod, ponto E-S. Através da janela cardíaca esquerda nos modos B e M: DIVEs, DIVEd, FS%, EF%, AEs. Foram observadas diferenças estatísticas entre as médias dos quatro grupos dos seguintes parâmetros: Aod, AEs, DIVDs, DIVDd, SIVs, SIVd, DIVEs, DIVEd, PLVEs, PLVEd, Vs, Vd e correlações estatísticas positivas entre Aod, AEs, SIVs, SIVd, PLVEs, PLVEd, Vd e a idade, entreAod, AEs, SIVs, SIVd, DIVEd, PLVEs, AEs/Aod e o peso e o perímetro torácico e entre Aod, AEs, SIVs, SIVd, DIVEs, PLVEs, Vd e a altura da cernelha. Houve influência tanto do sexo como da faixa etária sobre os valores de referência para equinos da raça Mangalarga Marchador, tendo os machos acima de 4 anos apresentados valores de medidas ventriculares maiores. O peso, altura e idade dos animais influenciaram da mesma forma os resultados, estando todos relacionados positivamente ao tamanho da estrutura cardíaca.

“…The Polar EquineR frequency meter for HR monitoring in the field test is essential for correct measurement, in addition to specifying the intensity of the exercise and analyzing the effects of training and loss of conditioning (Bonomo et al, 2014). HR at rest of the horse is related to body surface, metabolic index and autonomic balance specific to the species, race and individual, varying in adult horses between 35-45 beats / min., And may vary due to excitation during the exam.…”

The physiological and biochemical responses of the equine athlete, before, during and after physical exercise, are studied in the exercise physiology and, for this to start and muscle contraction occurs, for this it is necessary that the organism produces energy through the production of ATP, which occur in three processes, being alactic or lactic, the alactic process occurs through the metabolism of creatine phosphokinase (anaerobic form) and glucose through the Krebs cycle (aerobic form), whereas the lactic process occurs through the metabolism of lactate. During exercise, in an attempt to re-establish equine parameters, physiological changes occur. The physiology of exercise has been studying, through stress tests, performed on an ergometric treadmill or in the field, ways of obtaining parameters to evaluate the species. This study aimed to evaluate an essential tool that is the physiology of exercise on the physical conditioning of equine athletes, through parameters that observe the performance of these animals. For the methodology, a bibliographic survey of articles was made and directed to the physiology of equine exercise, in addition, necessary tools for the evaluation of equine athletes were addressed, being these neurological, cardiovascular, skeletal, and electrolytic responses. It is concluded that the use of tests for the evaluation of the athletic performance in horses performed by treadmill or in the field together with the physiological responses obtained by the action of exercise and training, is considered a valuable tool for equine sports medicine.
