Objective: The aim of the present study was to compare the effect of orders of resistance exercise, on the number of repetitions performed, rating of perceived exertion and muscle damage biomarkers. Method: One week after the 1 repetition maximum (1RM) test, 11 healthy untrained male participants completed two resistance exercise protocols including 4 sets of 4 exercises at 70% 1RM, with 2 min rest intervals between sets, exercises performed until failure and different orders: order A including: hack squat (HS), leg press (LP), leg extension (LE), and leg curl (LC), while order B was opposed to order A (LC, LE, LP, HS). Results: Increase of CK activity and lactate concentration was the same for order A and order B (P > 0.05). The total mean number of repetitions for HS and LC indicated a significant decrease (P < 0.05) when they were performed later in each exercise orders; however, no significant difference in the average of total number of exercise repetition was observed for neither resistance exercise orders (order A = 8.59 ± 1.61, order B = 8.78 ± 1.96). Rating of Perceived Exertion (RPE) was not significantly different between the exercise orders; however, the RPE increases for HS and LC when they were the last exercise orders. Conclusion: It can be concluded that both of the resistance exercise orders were equally effective in muscle damage parameters (CK, lactate), RPE and the average of the total number of exercise repetitions, although when the exercise session progressed, the number of repetitions performed to volitional failure decreased in last exercise in one single order, and the exercise order can influence performance.
