Abstract des Autors
Objective: To determine if a single-stage, submaximal fatigue test on a wheelchair ergometer would result in higher than expected energy expenditure. Design: An experimental survey design contrasting physiologic responses during peak graded exercise tests and fatigue tests. Setting: A rehabilitation science laboratory that included a prototypical wheelchair ergometer, open-circuit spirometry system, and heart rate monitor. Participants: Nine able-bodied non-wheelchair users (the NWC group: 6 men and 3 women, mean+/-SD age 30+/-7 yrs) and 15 manual wheelchair users (the WC group: 12 men and 3 women, age 40+/-9 yrs, time in wheelchair 16+/-9 yrs). No subject had any disease, medication regimen, or upper body neurologic, orthopedic, or other condition that would limit wheelchair exercise. Main Outcome Measures: Peak oxygen uptake (VO2) for graded exercise testing and during fatigue testing, using a power output corresponding to 75% peak aerobic capacity on graded exercise test. Results: In the WC group, VO2 at 6 minutes of fatigue testing was not significantly different from peak VO2. In the NWC group, VO2 was similar to the expected level throughout fatigue testing. Conclusion: Energy expenditure was higher than expected in the WC group but not in the NWC group. Fatigue testing may provide a useful evaluation of cardiorespiratory status in manual wheelchair users. Verf.-Referat
