Summary

Exhausting physical exercise damages muscular tissue. Among other factors, damage depends on training load and intensity. The aim of this study was to determine changes in enzymatic biomarkers in response to a football match. The study sample was composed of 30 football players aged between 18-35 years and male, divided into experimental (GE; N = 15) and control (GC; N = 15) groups. Blood samples from GE and GC individuals were withdrawn before and 24 hours after the match. The following enzymes were examined: total creatine kinase (CKt), cardiac muscle creatine kinase (CKMB), lactate dehydrogenase (LDH), and gamma-glutamyl transpeptidase (GGT). In GE individuals, there were significant changes (p<0.05) in CKt (334±203 and 860±553 U/L), CKMB (30±7 and 42±11 U/L), and LDH (417±86 and 547±84 U/L) between before and after the match, respectively; GGT remained unchanged. In GC individuals, levels were similar at the two time points. A football game is sufficiently aggressive to induce tissue damage, as evidenced by increased plasma levels of various enzymes. Enzyme clearance assessment might be a valuable tool for development of training programs.
