This study was designed to investigate the effect of 8 km training on the serum concentrations of the cardiac biomarkers troponin I (cTnI) and creatine kinase myocardial band (CK-MB) in 23 healthy racing camels (Camelus dromedarius). From each camel, 2 blood samples were collected; before training (T0) and within 2 h after training (T1). Serum concentrations of cTnI and CK-MB, and hematobiochemical profiles were estimated. Compared to a value of 7.21±1.9 ×109/L pre-training, neutrophils decreased significantly to 6.2±2.2 × 109/L post-training (P=0.05). Similarly, haemoglobin concentration decreased from 11.1±1.1 g/dL before training to 10.3±2.0 g/dL after training (P=0.0002). The MCV showed a similar pattern where it decreased from 26.0±1.3 (fl) pre-training to 24.0±3.6 (fl) post-training (P=0.01). Other haematological variables did not show any significant changes before and after training (P>0.05). The serum activity of AST increased from 85.5±12.8 U/L before training to 91.5±8.6 U/L after training (P=0.0001). Serum concentration of TP increased also from 54.2±8.7 g/L pre-training to 59.0±3.8 g/L post-training (P=0.04). On the contrary, the serum concentration of lactic acid decreased from 3.9±0.8 (mmol/L) before training to 3.3±0.4 (mmol/L) after training (P=0.004). Other biochemical variables did not show any significant changes before and after training (P>0.05). Before training the serum concentration of cTnI was 0.03±0.03 ng/mL; a value that did not differ significantly when compared to the value of 0.04±0.02 (ng/mL) after training (P=0.60). The CK-MB value differed significantly before and after training (0.47±0.1 ng/mL before training vs 0.48±0.8 ng/mL after training; P=0.004). In conclusion, the cardiac biomarker cTnI did not change significantly after training compared to baseline levels, a result that disagrees with values in camels after race. However, the CK-MB increased significantly after training compared to pre-training serum concentrations.
