Abstract
Al-Rahamneh HQ, Eston RG. Prediction of peak oxygen consumption from the ratings of perceived exertion during a graded exercise test and ramp exercise test in able-bodied participants and paraplegic persons. Objective To assess the accuracy of predicting peak oxygen consumption (V o 2peak) from a graded exercise test (GXT) and a ramp exercise test during arm exercise in able-bodied persons and persons with paraplegia using ratings of perceived exertion (RPEs). Design Each participant performed a GXT (started at 30W and increased by 15W every 2min) and a ramp exercise test (started at 0W and increased by 15W·min −1). Setting Universities' laboratories. Participants Able-bodied men (n=13; mean ± SD, 27.2±4.3y) and men with paraplegia (n=12; 31.1±5.7y). Six of the persons with paraplegia had flaccid paralysis as a result of poliomyelitis infection. The other 6 persons had complete spinal cord injuries with neurologic levels at and below T6. Intervention Not applicable. Main Outcome Measures Prediction of V o 2peak by extrapolating submaximal oxygen consumption (V̇ o 2) and RPE values to RPE 20 on the Borg 6 to 20 RPE scale. Results This study showed a very strong linear relationship between RPE and V̇ o 2 during the GXT and the ramp test for able-bodied persons ( R 2 ≥.95 and R 2 ≥.96, respectively) and persons with paraplegia ( R 2 ≥.96 and R 2 ≥.95, respectively). There was no significant difference between measured and predicted V o 2peak from RPEs before and including RPE 13, 15, and 17 during the GXT for persons with paraplegia ( P>.05). For the able-bodied participants, there was no significant difference between measured and predicted V o 2peak from RPEs before and including RPE 15 and 17 during the ramp exercise test ( P>.05). Conclusion The GXT provided acceptable predictions of V o 2peak for persons with paraplegia, and the ramp test provided acceptable predictions of V o 2peak for able-bodied persons.
