    To assess the validity of predicting peak oxygen uptake ([Formula: see text]) from differentiated ratings of perceived exertion (RPE) obtained during submaximal wheelchair propulsion.


    Three subgroups of elite male wheelchair athletes [nine tetraplegics (TETRA), nine paraplegics (PARA), eight athletes without spinal cord injury (NON-SCI)] performed an incremental speed exercise test followed by graded exercise to exhaustion ([Formula: see text] test). Oxygen uptake ([Formula: see text]), heart rate (HR) and differentiated RPE (Central RPEC, Peripheral RPEP and Overall RPEO) were obtained for each stage. The regression lines for the perceptual ranges 9-15 on the Borg 6-20 scale ratings were performed to predict [Formula: see text].


    There were no significant within-group mean differences between measured [Formula: see text] (mean 1.50 ? 0.39, 2.74 ? 0.48, 3.75 ? 0.33 L min-1 for TETRA, PARA and NON-SCI, respectively) and predicted [Formula: see text] determined using HR or differentiated RPEs for any group (P > 0.05). However, the coefficients of variation (CV %) between measured and predicted [Formula: see text] using HR showed high variability for all groups (14.3, 15.9 and 9.7 %, respectively). The typical error ranged from 0.14 to 0.68 L min-1 and the CV % between measured and predicted [Formula: see text] using differentiated RPE was ≤11.1 % for TETRA, ≤7.5 % for PARA and ≤20.2 % for NON-SCI.


    Results suggest that differentiated RPE may be used cautiously for TETRA and PARA athletes when predicting [Formula: see text] across the perceptual range of 9-15. However, predicting [Formula: see text] is not recommended for the NON-SCI athletes due to the large CV %s (16.8, 20.2 and 18.0 %; RPEC, RPEP and RPEO, respectively).

    It's funny that SCI people would be more in touch with their bodies than AB people.
