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.
