The purpose of this investigation was to compare physical work capacity (PWC), peak oxygen uptake (peak VO2), maximal pulmonary ventilation (VEmax), maximal heart rate (HRmax), and maximal blood lactate concentration (LAmax) for wheelchair ergometer (WERG) and arm crank ergometer (ACE) exercise. For this, wheelchair-dependent (n = 6) and able-bodied (n = 10) subjects completed a progressive intensity, discontinuous test for each mode of exercise. Each test was terminated by physical exhaustion and/or an inability to maintain a flywheel velocity of 180 m.min-1. Relatively high correlation coefficients were found between values obtained during the two modes of ergometry for PWC, peak VO2, VEmax, and HRmax. WERG exercise was found to elicit a significantly (P less than 0.05) lower PWC (by 36%), HRmax (by 7%), and LAmax (by 26%) than ACE exercise. Peak VO2 and VEmax, however, were similar for both exercise modes. These data suggest that either exercise mode may be used for fitness testing and training of people who cannot use their legs and that arm cranking may be a superior method to propel wheelchairs.
本研究的目的是比较轮椅测力计（WERG）和手臂曲柄测力计（ACE）运动时的身体工作能力（PWC）、峰值摄氧量（peak VO2）、最大肺通气量（VEmax）、最大心率（HRmax）和最大血乳酸浓度（LAmax）。为此，依赖轮椅的受试者（n = 6）和身体健全的受试者（n = 10）针对每种运动模式完成了一项递增强度的非连续测试。每次测试均因体力耗尽和/或无法维持180 m·min-1的飞轮速度而终止。在两种测力计模式下测得的PWC、peak VO2、VEmax和HRmax值之间发现了相对较高的相关系数。结果发现，与ACE运动相比，WERG运动时的PWC（降低36%）、HRmax（降低7%）和LAmax（降低26%）显著更低（P < 0.05）。然而，两种运动模式下的peak VO2和VEmax相似。这些数据表明，对于无法使用双腿的人，两种运动模式均可用于体能测试和训练，并且手臂曲柄运动可能是推动轮椅的更佳方法。
