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 (\[Vdot]O(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 \[Vdot]O(2)peak was calculated by extrapolating the submaximal rating of perceived exertion (RPE) and \[Vdot]O(2) values by linear regression to RPE20.Results:There were no significant differences between measured and predicted \[Vdot]O(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 P>0.05). However, the second perceptually guided exercise tests provided a more accurate prediction of \[Vdot]O(2)peak as reflected by narrower 95% limits of agreement and higher intraclass correlation coefficients.Conclusion:This study has shown that \[Vdot]O(2)peak may be predicted with reasonable accuracy from a perceptually guided exercise test, especially after a full familiarization trial.
