“…Furthermore, similarly to effort, proxies of perception of effort can function as independent or dependent variables, depending on the research question. When serving as the independent variable, researchers prescribe RPE values (see single-item scales below) so that participants exercise at a specific intensity-for instance, prescribing them to terminate a set when reaching an RPE of 8/10 [84]. When perception of effort is the dependent variable, researchers assess the impact of certain exercise interventions by collecting participants' RPE at specific intervals during or after the session [53].…”

Effort and the perception of effort have been extensively studied across multiple disciplines, resulting in disparate definitions across the literature. Inconsistencies in definitions impede scientific progress by blocking effective communication between and within disciplines. Here, we introduce a resource-based framework that comprehensively defines and connects effort and perception of effort, and provide a detailed analysis of these constructs. We define effort in a way that applies to all biological entities, voluntary and involuntary actions, and successful and unsuccessful actions. We define perception of effort such that it builds on our definition of effort without conflating it with other experiences. Our definition of perception of effort also aligns with various explanations regarding its proposed functions and mechanistic underpinnings. We explore the latent nature of these constructs, their employment as independent and dependent variables, and their associations. Our framework also seeks to bridge the gap between cognitive and physical effort and perception of effort, which have been primarily developed in isolation. We anticipate that our framework will facilitate a deeper understanding of these constructs, refine research methodologies and promote interdisciplinary collaborations.

“…The Borg scale, or rating of perceived exertion (RPE), represents a widely applied tool to obtain individual perceived exertion in various settings ( Borg, 1970 ; Lollgen et al, 1980 ; Boxman-Zeevi et al, 2022 ). Both parameters have been shown to correlate with other indicators of physical strain such as heart rate (HR), relative VO 2 , feelings of pain, respiratory fatigue, and reaching onset of blood lactate accumulation ( Borg et al, 1985 ; Scherr et al, 2013 ).…”

Introduction: Mechanic power output (MPO) and oxygen consumption (VO2) reflect endurance capacity and are often stated relative to body mass (BM) but less often per skeletal muscle mass (SMM). Rating of perceived exertion (RPE) has previously shown conflicting results between sexes at submaximal intensities. Individual body composition, however, largely differs due to sex and training status. It was the aim of this study to evaluate RPE of untrained and trained individuals of both sexes considering body composition and to estimate whether RPE could be improved as a tool to determine endurance capacity.Methods: The study included 34 untrained adults (age 26.18 ± 6.34 years, 18 women) and 29 endurance trained (age 27.86 ± 5.19, 14 women) who were measured for body composition (InBody 770, InBody Europe B.V., Germany) and tested on a treadmill (Pulsar, H/P/Cosmos, Germany) for aerobic capacity (Metalyzer 3B, Cortex Biophysik GmbH, Germany) in an all-out exercise test applying the Bruce-protocol. VO2, MPO, heart rate (HR), and RPE were obtained at each exercise stage. VO2 and MPO were calculated per BM and SMM. RPE values were correlated with absolute VO2 and MPO, as well as relative to BM, and SMM. HR values and the parameters’ standardized values served for comparison to standard procedures.Results: VO2 and MPO were higher in men compared to women and in trained compared to untrained participants. No differences between groups and sexes exist when VO2 and MPO were calculated per BM. When calculated per SMM, VO2 and MPO indicate opposite results already at low intensity stages of exercise test. RPE values had highest correlation with MPO per SMM (R2 = 0.8345) compared to absolute MPO (R2 = 0.7609), or MPO per BM (R2 = 0.8176). Agreement between RPE and MPO per SMM was greater than between RPE and HR (p = 0.008).Conclusion: Although RPE represents a subjective value at first glance, it was shown that RPE constitutes a valuable tool to estimate endurance capacity, which can be further enhanced if individual body composition is considered. Furthermore, MPO and VO2 should be considered relative to SMM. These findings might help to avoid over-exertion, especially among untrained people, by adjusting the training intensity for each subject according to the individual strain evaluated in an exercise test based on individual body composition.
