Failure sets rapidly promote muscle strength and endurance. Cluster sets are highly efficient in developing maximum power and strength. This study equated the volume and intensity indexes in two types of resistance training (failure sets versus cluster sets) to investigated high sensitivity Cardiac Troponin I (hscTnI), N-terminal proBNP (NT-proBNP), rate of perceived exertion (RPE) and heart rate (HR) responses. 12 male athletes (mean age 22.16 ± 2.48 y) voluntarily preformed two types of training protocols (failure sets and cluster sets) separately with pretest and 30 minutes, 4, 12 and 24 hours of posttest. Both protocols consisted of 9 movements in equal training volumes and intensity range (8-10 RM); three cycles of 8 to 10 rep were performed for failure sets and nine cycles of 2 to 3 rep were performed for cluster sets. During the training, the mean HR of the third cycle was lower than the second cycle in both training types (P<0.05). Only in the first cycle, RPE in cluster sets was lower than the failure sets with the effect size (d=1.60) (P=0.001). 24 hours after the intervention, mean hscTnI increased in both failure (d=2.07) and cluster (d=1.61) sets (P<0.05). The mean Nt-proBNP in the failure sets was higher 24 hours after the intervention than the other posttests while this increase in the cluster sets was observed only in comparison with the baseline and 30 minutes after the training (P<0.05). When failure and cluster sets are exactly equated, their intervention effects on myocardium injury markers are close together. No matter what type of training is used in the protocol, the greatest effect of training stimulus belongs to the total training volume.
