Twenty-one disabled subjects, who use a wheelchair as a normal means of locomotion, completed a continuous, increasing workrate test to subjective exhaustion on a wheelchair ergometer. The subjects were classified into tetraplegic (n = 8), high lesion paraplegic (n = 6), and low lesion paraplegic (n = 7) groups, and linear regression analyses to predict oxygen uptake (l/min) from power output (watts) were carried out for each group. Tetraplegics exhibited a non-significant correlation (r = .21) between power output and oxygen uptake. This was possibly due to their low maximal attainable oxygen uptake and limited range for these variables. A significant relationship was noted in both paraplegic groups (r = .93), and analysis indicated a lack of significant difference (p = .88) in the regression equations between the two groups. The high and low lesion paraplegic group measures were combined to produce a single regression equation given by VO2 (l/min) = .108 + .0267 X Power (watts).
21名以轮椅作为日常移动方式的残疾受试者，在轮椅测力计上完成了一项持续增加工作强度直至主观疲劳的测试。受试者被分为四肢瘫痪组（n = 8）、高位损伤截瘫组（n = 6）和低位损伤截瘫组（n = 7），并对每组进行了线性回归分析，以根据功率输出（瓦特）预测摄氧量（升/分钟）。四肢瘫痪者的功率输出与摄氧量之间呈现出不显著的相关性（r = 0.21）。这可能是由于他们的最大可达到摄氧量较低以及这些变量的范围有限。两个截瘫组均呈现出显著关系（r = 0.93），分析表明两组之间回归方程不存在显著差异（p = 0.88）。将高位和低位损伤截瘫组的测量值合并，得出一个单一的回归方程：摄氧量（升/分钟）= 0.108 + 0.0267×功率（瓦特）。
