健康的青年男子在良好的训练中约占最大摄氧量的80% （Mitchell. 1958）。在观察期间，这个功可以保持在一个稳定的状态。通常是四分钟。正常男性受试者的普华永道170高于女性受试者。在我们的研究中，这种差异与体重无关。这一结果与其他工作者的研究结果一致（Adams and Linde, 1961; Rodahl et alii）。1961)。在我们的正常人群中，我们发现PWC 170与年龄之间没有相关性。然而。大多数受试者在15至25岁年龄组（表II），为了得出更有效的结论，我们应该研究更大的老年患者群体。在正常受试者中。普华永道170值在6至12个月内是可重复的。然而。同时研究的总通风量变化较大。用每分钟千卡来计算“功”（Snellen, 1960）与用每小时公里的跑步机速度作为普华永道170指数相比，没有任何优势。表三至表六建立了我们对患者残疾的临床估计与普华永道170测量之间的密切关系。这项测试使我们能够定量地评估手术或药物治疗可能产生的变化。
healthy young men in good training is about 80% of the maximum oxygen uptake (Mitchell. 1958). This amount of work can be maintained in a steady state for the period of observation. which was usually four minutes. Normal male subjects were found to have a higher PWC 170 than female subjects. This difference was independent of body weight in our series. This result is in agreement with those of other workers (Adams and Linde. 1961; Rodahl et alii. 1961). In our normal population group, we found no correlation between PWC 170 and age. However. the majority of subjects were in the 15 to 25 years age group (Table II), and to draw a more valid conclusion we should study larger groups of older patients. In the normal subjects. the PWC 170 values were reproducible within a period of six to 12 months. However. the total ventilation studied at the same time was more variable. The calculation of "work" in kilocalories per minute (Snellen. 1960) possessed no advantage over the use of the treadmill speed in kilometres per hour as the PWC 170 index. Tables III to VI establish a close relationship between our clinical estimation of the patient's disability and the measurement of the PWC 170. This test enables us to evaluate quantitatively changes which may accrue from surgical or medical treatment.
