Abstract
- The purpose of this study was to determine the effect of work rate increment on peak oxygen uptake (\(\dot VO_2\)peak) during wheelchair ergometry (WCE) in men with quadriplegia due to cervical spinal cord injuries (CSCI). Twenty-two non-ambulatory subjects (aged 20–38 years) with CSCI were divided into two groups based on wheelchair sports classification (n = 12 for IA group and n = 10 for IB/IC group). Subjects underwent three different, continuous graded exercise tests (spaced at least 1 week apart) on an electronically braked wheelchair ergometer. Following a 3-min warm-up, the work rate was increased 2, 4, or 6 W · min−1 for the IA group and 4, 6, or 8 W · min−1 for the IB/IC group. Ventilation and gas exchange were measured breath-by-breath with a computerized system. Repeated-measures ANOVA showed no significant difference among the three protocols for \(\dot VO_2\)peak in the IA group (P>0.05). The mean (SD) \(\dot VO_2\)peak values (ml · kg−1 · min−1) were 9.3 (2.4), 9.4 (3.2), and 8.4 (2.6) for the 2, 4, and 6 W · min−1 protocols, respectively. In contrast, the IB/IC group showed a significant difference among the protocols for \(\dot VO_2\)peak (P
