“…It should be warned that CK-MB levels alone do not produce important information on the cardiac integrity of horses submitted to exercise. On the other hand, studies have suggested that the increase in the serum enzyme activity occurs due to the transitory increase in the permeability of the sarcolemma in the absence of histological lesions [28,29]. Positive correlations were observed for cTnI and CK-MB in the present study.…”

Cardiac biomarkers are potentially useful to identify primary or secondary cardiac muscle damage in horses and higher values of cardiac troponin have also been seen after high intensity exercise. The objective of this study was to investigate the effect of cavalcade of different distances on the serum concentrations of cardiac troponin I (cTnI) and creatine kinase myocardial band (CK-MB) in Mangalarga Marchador horses. Fifteen clinically normal geldings (age 6.2 ± 1.2 years, weight 420 ± 58 kg) were distributed into three groups of five animals each. The groups were submitted to cavalcade along 4 km (G4), 8 km (G8), and 20 km (G20) at mean speeds of 15 km h , respectively. From each horse, blood samples were collected after and post-exercise. Serum cTnI and CK-MB concentrations were determined with a solid-phase chemoluminescence immunoassay. The assay has an analytical sensitivity of 0.02 ng mL-1. The concentration of blood lactate was analyzed using an i-STAT portable clinical analyzer. After exercise, increases (P < 0.01) in cTnI and CK-MB concentrations were observed in G4 and G8. No changes (P > 0.05) in lactate concentration were observed post-cavalcade in all groups. Power tests values were 1.0 for cTnI and CK-MB, 0.63 for lactate. Positive correlations (0.4 < r < 0.5) were observed between cTnI and CK-MB. The changes in cTnI and CK-MB concentrations post-exercise is indicative of myocardial cell injury in healthy Mangalarga Marchador horses, which could be considered as an adaptation to physical exercise.

“…Some of these changes have been studied in equestrian sports such as flat racing [2][3][4] , endurance [5][6][7] , show jumping [8,9] , eventing [10] , reining [11] , marcha [12] , cavalcade [13] , and polo [14,15] . However, to the best to our knowledge, there is no such a study focused on jereed horses.…”

The aim of this study is to evaluate physical, haematological and biochemical changes in horses after acute exercise in a jereed game. Jereed is a traditional Turkish equestrian team sport. A total of 14 horses were included in this study. All horses were Arabian stallions aged between 4-14 years old. Respiration rate, heart rate, capillary refill time, mucous membrane and skin turgor (as an indicator for dehydration) were measured and blood samples were collected before the exercise (T0), immediately after first period (T1) and second period (T2), after 30 min (T3) and 60 min of recovery time (T4). Blood samples were analyzed for total cell counts and for determination of lactate, glucose, urea, total protein, albumin, globulin, calcium, magnesium, phosphorous, chloride, sodium, potassium, creatinine kinase, lactate dehydrogenase, aspartate aminotransferase and alkaline phospahatase. All parameters were analyzed using Linear Mixed effect model to evaluate changes of repeated measurements at 5 different time points and LSD was used as post-hoc test. Exercise caused significant increases in heart rate (P<0

“…A gravidade da condição nem sempre se relaciona à intensidade do exercício (HARRIS & MAYHEW, 2000). O diagnóstico da SRE é baseado nos sinais clínicos e na elevação da concentração sérica da creatina cinase (CK), do lactato desidrogenase (LDH) e da aspartato transaminase (AST) (TEIXEIRA-NETO et al, 2008).…”
