Participants
In accordance with an alpha less than .05 (2-tailed) and 80% power, it was determined that a meaningful effect size would be obtained from a sample of greater than 30 participants.25 Therefore, 16 men and women of able-bodied status and 15 men and women with poliomyelitis volunteered to take part in the study. Participants with poliomyelitis had flaccid paralysis of the lower limbs. The inclusion criteria were provision of written informed consent, less than 45 years of age, no prior experience
Descriptive Statistics
Participant descriptives can be observed in table 1. Men and women with poliomyelitis were significantly older than their able-bodied counterparts (t7.21=−10.58, P<.01) and (t6.37=−7.44, P<.01), respectively. Although there was no significant difference in body mass between able-bodied participants and those with poliomyelitis, regardless of sex (P>.05), able-bodied men and women were significantly taller than their counterparts who had poliomyelitis (t15=2.14, P<.05) and (t12=4.76, P<.01),
Discussion
This study assessed the physiologic and perceptual responses of able-bodied participants and participants with poliomyelitis during arm-crank exercise to volitional exhaustion. The results demonstrate strong relationships between the RPE and V̇o2, heart rate, V̇e and PO during an arm-crank exercise, regardless of sex or participants' status. As such, the study provides evidence that persons with poliomyelitis can perceptually rate their level of exertion in relation to measured physiologic
Conclusions
This study has provided further evidence that RPEs are strongly related to physiologic markers of exercise intensity during arm exercise (R2>.87), irrespective of sex or participants' status. Accordingly, persons with poliomyelitis can accurately rate their level of exertion in relation to measured physiologic values during arm exercise. Future research studies could examine whether the RPE may be accurately used to prescribe and monitor appropriate exercise intensities during arm exercise with
