Abstract

This study compared whether the perception of effort measured on a repetition-by-repetition basis during continuous sets to failure are different between squat (SQ) and bench press (BP). After determining the 1RM value in both SQ and BP, eighteen participants (28.2 ± 5 years, 50% females) performed seven sets to failure per exercise, separated by 24-h to 48-h, alternating SQ and BP, using the following relative loadranges 30<40%; 40<50%, 50<60%, 60%<70%, 70<80%, 80<90% and >90%. The mean accelerative velocity (MAV) and Rating of Perceived Exertion (RPE) using the OMNI-RES (0-10) scale were measured for every repetition of each set. The ability of the OMNI-RES (0-10) scale to identify velocity changes during continuous sets to volitional failure and to distinguish loading zones divided into 10% slots, from 30 to 100% of 1RM was confirmed for both SQ and BP. The RPE values measured at (i) the first repetition; (ii) the repetition where MAV peaks; (ii) the repetition where MAV drops by ≤10% compared the maximum and (iv) the last repetition, showed no differences (p>0.05, d<0.2) between exercises. In conclusion, the same RPE scores can be applied to both exercises, for either estimating the relative load and monitoring changes in MAV during continuous sets to failure.
