The purpose of this study was to investigate the cardiac biomarkers like cardiac troponin T (cTnT), cardiac troponin I, and creatine kinase-MB (CK-MB) and the cell damage biomarkers including creatine phosphokinase (CPK), C-reactive protein (CRP), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in response to a short-duration high-intensity competition with correction of the post-exercise raw data with the plasma volume loss in trained athletes. Thirty-two male athletes (age, 26.9±4.7 years) competed in 8 min high-intensity competition. The competition items included: running for 400 meters; three-stage deadlifting; bar pulling up; and 30 kg kettlebell swinging. Venous blood samples were obtained before and immediately after the competition and biomarkers analysed. Plasma volume changes were estimated from haemoglobin and haematocrit readings before and after the competition. A significant increase was shown immediately after the competition compared to resting in cTnT, AST, ALT, CPK, and CRP (P<0/001). CK-MB showed no significant difference. When raw data were corrected for plasma volume loss, CPK showed a significant increase (P<0.001), and LDH and CK-MB a significant decrease (P<0.001), however cTnT, AST, ALT and CRP showed no significant difference. The plasma volume loss can affect the response of cardiac and cellular damage biomarkers to exercise. High-intensity competition for 8 min did not elevate the cardiac biomarkers, but elevated the muscle biomarkers.
