Triathlon is becoming more popular sport due to recognition of the posi-tive effects of triathlon. Generally, participants in these strenuous activi-ties are well considered as healthy individuals pursuing a healthy life-style. However, there is still controversy on the beneficial effects of pro-longed exercise training and endurance sport events. The duration of exercise required to elicit cardiac dysfunction and the mechanisms un-derlying this phenomenon have not been fully elucidated. There are only limited data in literature for exercise-induced changes of cardiac and muscle damage biomarkers in athletes participating in different tri-athlon distances. Monitoring cardiac and muscle damage biomarkers in triathletes participating in different triathlon distances will help re-searchers, coaches, and athletes better understand how to design training cycles minimizing overtraining and injury risk. Therefore, the purpose of the present study was to examine for evidence of blood bio-markers during triathlon events of two different distances such as stan-dard- and ultradistance triathlon in male triathletes. The results of the present study showed that ultradistance showed greater muscle dam-age markers such as creatine kinase, myoglobin and lactate dehydro-genase than standard-distance. We also found that the distance of tri-athlon did not lead to an increase of troponin T in male triathletes.
