Participants’ REPfailure, RPEfatigue, and %REPfatigue during bench press exercises performed with different load distributions, velocities, and loads.

REPfailure, number of repetitions performed to failure; RPEfatigue, rate of perceived exertion at fatigue onset (i.e., involuntary reduction of lifting velocity); %REPfatigue, number of repetitions at fatigue onset normalized as a percentage of REPfailure; SD, standard deviation; Load, load corresponding to 50% (1-RM50), 65% (1-RM65), and 80% (1-RM80) of 1 repetition maximum; Velocity, velocities corresponding to 50% (V50), 70% (V70), and 90% (V90) of the maximum concentric velocity; Distribution, narrow (Dnarrow) and wide (Dwide) load distribution on the barbell.
