“…RPE values were classified based on the ACSM Position Stand 10 as very light (<9), light (9-11), moderate (12-13), vigorous (14)(15)(16)(17), and nearmaximal to maximal (≥18). Corresponding respiratory measures were averaged across each stage fitting into a respective category.…”

“…6 There have been a few studies in which wheelchair users' metabolic responses and RPE were recorded during wheelchair exercises and hand-cycling training, 7-9 but they have generally used treadmill or hand cycling at relatively high intensities for elite wheelchair athletes. 10,11 Daily activities at lower intensities have greater relevance for the majority of wheelchair users. One of the strategies for promoting regular physical activities is assisting people in making close estimates of daily physical activity levels that are conducive for maintaining satisfactory physical capacity.…”

Study design: Each participant performed a series of wheelchair exercises equivalent in intensity to minimal functional speed (1 m s − 1 ), functional walking speed (1.3 m s − 1 ), a relatively challenging speed (1.6 m s − 1 ) and a self-selected speed. Each participant also completed a graded exercise test (GXT) to volitional exhaustion (VO 2peak ). Objectives: The purpose of this study was (1) to assess the physical capacity of wheelchair users as they undertake typical mobility activities and (2) to investigate how closely the components of a differentiated model of perceived exertion mirror wheelchair users' own perception of exertion. Methods: Eleven (eight males and three females) spinal cord-injured or congenitally impaired wheelchair-dependent participants volunteered for the study. Differentiated ratings of perceived exertion (RPE _arm and RPE _respiration ) and oxygen uptake (VO 2 ) and heart rate were recorded during each exercise. Results: The mean comfortable speed at which the participants propelled their own wheelchairs on the wheelchair ergometer was 1.1 ± 0.2 m s − 1 . Speeds of 1 m s − 1 and 1.3 m s − 1 are typical of everyday functional propulsion. The corresponding RPE_ respiration and RPE_ arm ranged from 7 to 13 on the Borg scale; the %VO 2peak measured in these trials ranged from 37 to 80% VO 2peak. For propulsion intensities used in the present study-low, moderate, high and graded exercise intensity-no difference could be observed between RPE _respiration and RPE _arm . There were no significant differences between RPE _arm and RPE _respiration at the termination of the GXT. Conclusion: The current study showed potential for the use of RPE to assess and monitor daily wheelchair propulsion intensity in individuals with paraplegia.

Study design: Each participant completed two submaximal, perceptually guided arm crank exercise tests and a graded exercise test (GXT) to volitional exhaustion. Objective: To assess the validity of a submaximal, perceptually guided exercise test to predict peak oxygen uptake ( . VO 2 peak) during arm cranking in paraplegic individuals. Setting: University of Jordan, Amman, Jordan. Participants: Eleven men with paraplegia as a result of poliomyelitis infection or spinal cord injury completed two submaximal perceptually guided exercise tests and an arm crank GXT to volitional exhaustion. Main outcome measures: The prediction of .VO 2 peak was calculated by extrapolating the submaximal rating of perceived exertion (RPE) and .VO 2 values by linear regression to RPE20. Results: There were no significant differences between measured and predicted .VO 2 peak from the three submaximal ranges of the RPE (that is, 9-13, 9-15 and 9-17) when extrapolated to RPE20 during both perceptually guided exercise tests (all P40.05). However, the second perceptually guided exercise tests provided a more accurate prediction of .VO 2 peak as reflected by narrower 95% limits of agreement and higher intraclass correlation coefficients. Conclusion: This study has shown that .VO 2 peak may be predicted with reasonable accuracy from a perceptually guided exercise test, especially after a full familiarization trial.

Abstract: These data suggest that RPE is effective in controlling moderate and vigorous intensities throughout a 20-min handcycling exercise session for SCI participants.
