The purpose of the present study is to investigate effect of exercise to failure sets and cluster sets on biomarkers of cardiac injury. Methods: Twelve trained male athletes with a mean age of 23.20 ± 2.25 years were voluntarily selected. Two kinds of exercises’ concentric failure sets and cluster sets done separately with pre-test and 30 minutes, 4, 12 and 24 hours follow-up. Both failure sets and cluster sets include nine exercises with a weight in equal intensity zone (12-15RM) and training volumes. Result: in final cycling of exercise both protocols has shown decreased in mean heart rate, especially in cluster sets this decrease with high effect size (ES) (d = 0.99) was most obviously (P <0.05). Only in the first period of monitoring, perceived exertion level was different and which was higher in concentric failure sets ES (d = -3.59) (P <0.05). hscTnI mean after the intervention, at the 24 hours later monitoring showed large ES (d = 0.90) in failure sets (P <0.05). During all periods of two protocol follow up (with the exception of a 24-hour monitoring) a cardiac Nt-proBNP elevated above the baseline levels, which peaked 4 hours later monitoring with ES (d = 1.35) in failure sets. Conclusion: Performing resistance exercise to failure increases the biomarkers of cardiac injury levels and 24-hour recover period may not be sufficient.
