Cardiac biomarkers
The cardiac biomarkers results were presented in Table 3.
The results showed that the highly significant increase in CTnI concentration after exercise (0.03 ± 0.01 ng/mL) than before exercise (0.01 ± 0.00 ng/mL). The concentration of CTnT after exercise (28.95 ± 4.52 pg/mL) showed a highly significant increase than before exercise (13.64 ± 0.71 pg/mL). Assessment of NT-proBNP concentration revealed highly significant increased concentration of this biomarker in horses after exercise (32.87 ± 3.92 pg/mL) than before exercise (14.78 ± 1.01 pg/mL). Concentration of CK-MB after exercise (151.56 ± 39.55 U/L) showed a highly significant increase than before exercise (91.06 ± 27.96 U/L).
