Table 1.
RPE outcomes that will be extracted from included studies
Outcome | Description | Example |
Scale type | Which scale was used | Borg 6–20, CR10, CR100, OMNI, repetitions in reserve scale, repetitions to failure scale |
Instructions given to participants | Which instruction was given to participants for reporting RPE | – |
Used terms | Which terms were used in instructions given to participants | Fatigue, heavy, hard or discomfort |
Purpose of using RPE | Which is the purpose of using RPE | Prescribe, monitor or adjust the load |
Estimation and production paradigms | Which paradigm was used | Estimation—RPE is reported in response to a predefined load. Production—the participant self-regulated exercise intensity by RPE level proposed by authors |
Exercise intensity (when production paradigm was applied) | Targeted internal load proposed by authors | Mild, moderate or high intensity |
Strategy for load adjustment | Which strategy was used to adjust load | Increase or reduce external load, no of sets, repetitions or exercises |
Local vs global RPE | Participants were instructed to report RPE for which part of the body | Specific muscle groups, cardiovascular system, or whole body |
Moment of RPE acquisition | RPE was collected at which moment of the session | After each set, exercise or session |
Exercises in which RPE was collected | RPE was collected during which exercises | Leg extension, leg press or squat |
CR, category ratio; RPE, rating of perceived effort.
