Abstract

This study investigated the reliability of the session RPE scale to quantify work during high intensity (HIP), moderate intensity (MIP), and low intensity (LIP) resistance training. Nine men (24.7 + 3.8 years) and 10 women (22.1 rt 2.6 years) performed each intensity twice. Each protocol consisted of one set of five exercises: back squat, bench press, overhead press, biceps curl, and triceps pushdown. The HIP consisted of 4-5 repetitions at 90% of the subject's 1 repetition maximum (I-RM). The MIP consisted of 10 repetitions at 70% 1-RM and the LIP consisted of 15 repetitions at 50% 1-RM. RPE wm collected following the completion of each set and thirty minutes post-exercise (session WE). Session RPE was higher for the HIP than MIP and LIP (p<0.05). Performing fewer repetitions at a higher intensity is perceived to be more difficult than performing more repetitions at a lower intensity. The intraclass correlation coefficient for the session RPE was 0.88. The session RPE is a reliable method to quantify various intensities of resistance training.
