The results of a 12-minute walking test and the maximum working capacity (Wmax) achieved on a bicycle ergometer were compared in 25 patients with chronic obstructive lung disease. There was a significant correlation between the distance walked in 12 minutes and the Wmax that each patient could achieve on the bicycle ergometer (r = .68, p less than .001). The maximum oxygen uptake on both tests was not significantly different.
对25例慢性阻塞性肺疾病患者的12分钟步行试验结果与在自行车测力计上测得的最大工作能力（Wmax）进行了比较。12分钟内行走的距离与每位患者在自行车测力计上所能达到的Wmax之间存在显著相关性（r = 0.68，p < 0.001）。两项测试中的最大摄氧量无显著差异。
