Proximity to failure and total repetitions performed in a set influences accuracy of intraset repetitions in reserve-based rating of perceived exertion. J Strength Cond Res 35(2S): S158-S165, 2021-The aim of this study was to assess the accuracy of predicting repetitions in reserve (RIR) intraset using the RIR-based rating of perceived exertion (RPE) scale.

Article Synopsis
- The study compared two methods of load assignment—percentage of one-repetition maximum (1RM) versus rating of perceived exertion (RPE)—in resistance-trained males during an 8-week workout program.
- Both groups showed significant increases in strength for the squat and bench press, as well as muscle thickness, but no significant differences between the two methods were found.
- RPE-based loading might offer a slight strength advantage for most individuals, suggesting it could be a viable option in resistance training.
