영문 초록

The purpose of the present study was to investigate cardiac damage biomarkers after a triathlon race in elite and non-elite athlete groups. Fifteen healthy men participated in the study. Based on performance, they were divided into elite athlete group (EG: n＝7) and non-elite athlete group (NEG: n＝8). Participants’ blood samples were obtained during four periods: before, immediately, 2 hours and 7 days after finishing the race. creatine kinase (CK), creatine kinase-myoglobin (CK-MB), myoglobin, and lactate dehydrogenase (LDH) were significantly increased in both groups immediately after, and 2 hours after finishing the race (p＜.05). CK, CK-MB, and myoglobin were completely recovered after 7 days (p＜.05). Hematocrit (Hct) was significantly decreased in both groups (p＜.05) 7 days after the race. LDH was significantly decreased in the EG (p＜.05) only 7 days after the race. Homoglobin (Hb) was significantly decreased in the NEG (p＜.05) only 2 hours after the race. Although cardiac troponin T (cTnT) was significantly increased in the EG but not in the NEG 2hours after the race (p＜.05), there was no group-by-time interaction. cTnT was completely recovered in both groups 7 days after the race. In conclusion, cardiac damage occurs during a triathlon race and, is greater in elite than in non-elite. However, all cardiac damage markers return to normal range within 1 week.
