To develop a field test to estimate maximal oxygen consumption (VO2max) in wheelchair users, 30 men (means age = 34.3 years) were subjected to progressive arm-crank ergometer testing with directly measured VO2max. Additionally, they performed a modified 12-minute wheelchair propulsion test for distance. Field testing was conducted within two weeks of the VO2max determination, using a standardized wheelchair (Quickie II) on a 0.1-mile indoor synthetic running track. Average peak power output and VO2max were 540 kg.m.min-1 and 22.0 ml.kg-1.min-1, respectively. The mean (+/- 1SD) wheelchair propulsion distance was 1.11 +/- 0.24 miles. Correlation of the field test data with the VO2max was highly significant (r = 0.84; p less than .001). The regression of distance in 12 minutes plotted against VO2max yielded the following equation: wheelchair propulsion (miles) = 0.370 + 0.0337 (VO2max, ml.kg-1.min-1), where the standard error of estimate = 0.13. These findings suggest that field testing can provide a good estimate of VO2max in selected wheelchair users.
为开发一种用于估计轮椅使用者最大摄氧量（VO2max）的现场测试方法，对30名男性（平均年龄 = 34.3岁）进行了渐进式手臂曲柄测力计测试，并直接测量VO2max。此外，他们还进行了一项改良的12分钟轮椅推进距离测试。在确定VO2max后的两周内进行现场测试，使用标准化轮椅（Quickie II）在一条0.1英里的室内合成跑道上进行。平均峰值功率输出和VO2max分别为540 kg.m.min-1和22.0 ml.kg-1.min-1。轮椅推进的平均（±1SD）距离为1.11±0.24英里。现场测试数据与VO2max的相关性非常显著（r = 0.84；p <.001）。以VO2max为横坐标绘制的12分钟内推进距离的回归方程如下：轮椅推进距离（英里）= 0.370 + 0.0337（VO2max，ml.kg-1.min-1），其中估计标准误差 = 0.13。这些结果表明，现场测试可以为选定的轮椅使用者提供良好的VO2max估计值。
