Abstract

We compared the velocity feedback method (VEL) vs the perceptual response (RPE), with no velocity feedback, to estimate changes in movement velocity during continuous sets terminated at 10%, 20% and 40% of velocity decreases in the bench press exercise using either 50% or 75% of the one repetition maximum (1RM). After five sessions of familiarization and determining the 1RM, nineteen males (24.5±6 years) and nine females (30.4±8 years) underwent two identical six-day testing sessions over two weeks (twelve days in total) using the VEL (first six sessions) or the RPE method (last six sessions). The average velocity and the OMNI-RES (0–10) scale score were measured for every repetition of each set. Under VEL, the sets terminated after completing two consecutive repetitions below the pre�established velocity threshold. During RPE, the sets stopped when the participants reached a previously obtained OMNI-RES score linked to the specific tested velocity thresholds. A linear mixed-effects model setting velocity thresholds, method, and their interaction as fixed effects, and participants as random components was conducted. No differences (p>0.05) between methods were observed for the absolute (m.s-1) and percentage of velocity decreases or the total number of repetitions using both 50% and 75% of 1RM. Nonetheless, compared to VEL, fewer repetitions (p<0.01) linked to non-desirable neuromuscular adaptations were completed under RPE. In conclusion, although no differences between methods for estimating changes in velocity were identified, the RPE could be preferable to the VEL method to reduce the number of repetitions performed under the prescribed threshold.
