Each participant completed an arm-crank ramp exercise test to
volitional exhaustion. OBJECTIVE: To assess the utility of the rating of
perceived exertion (RPE) to predict peak oxygen uptake (VO(2)peak) during arm
ergometry in able-bodied participants and those with poliomyelitis. SETTING:
University of Jordan, Amman, Jordan. PARTICIPANTS: In all, 16 able-bodied and 15
participants with poliomyelitis completed an arm-crank ramp exercise test to
volitional exhaustion. MAIN OUTCOME MEASURES: The prediction of VO(2)peak is
calculated by extrapolating the sub-maximal RPE and VO(2) values by linear
regression to RPE 20. RESULTS: For the able-bodied participants, there were no
significant differences between measured and predicted VO(2)peak from the three
sub-maximal ranges of the RPE (RPEs before and including RPE 13, 15 and 17, P >
0.05). For the participants with poliomyelitis, the VO(2)peak predicted from RPEs
before and including RPE 13 was significantly higher than measured VO(2)max (P <
0.05). The 95% limits of agreement of able-bodied participants for RPE 13, 15 and
17 (-3 +/- 14, -1 +/- 10 & 0 +/- 8 ml kg(-1) min(-1), respectively) were lower
than those observed for poliomyelitis participants (6 +/- 19, 2 +/- 12 and 1 +/-
9 ml kg(-1) min(-1), respectively). CONCLUSION: This study has shown that the
estimation of VO(2)peak from submaximal RPE during arm ergometry is generally
more accurate in able-bodied participants in comparison with those with
poliomyelitis.
