Standard exercise testing (ET) comprises progressive exercise provocation with cardiovascular monitoring. Exercise tolerance is estimated by workload. Cardiopulmonary exercise testing (CPX) is a non-invasive measurement of ventilatory gas exchange which provides more accurate quantifications of cardiorespiratory fitness (CRF). Workload is usually increased stepwise in ET and continuously (ramp) in CPX. Our aim was to examine the comparability of the results. Thirty two healthy volunteers (17 females/15 males, age 26.8±6.1 years, BMI 24.5±3.0) underwent exercise testing on a bicycle ergometer up to maximum physical exhaustion; under ramp protocol (CPX) and 2-7 days later with a stepwise increase of workload (ET). We compared the physical work capacity under both methods at maximum workload, at heart rate of 150 and 170 beats/min (PWC150 and PWC170), and the exercise duration. We found that there were no statistically significant differences in the maximum heart rate (CPX: 177.1±11.7/min vs. ET: 178.5±11.2/min) or maximal workload (CPX: 219.8±50.6 vs. ET: 209.4±42.5). PWC150 and PWC150/kg were higher with CPX than those with ET (156.6±51 vs. 146.4±42.3, p<0.001 and 2.1±0.5 vs. 1.9±0.4, respectively, p<0.001). Exercise duration was almost equal (12.1 vs. 11.3 min). We conclude that overall physical performance was higher with CPX. Since the results are similar, we recommend the CPX: wattage and other parameters in performance assessment are to be determined directly, interpolations are obsolete.
标准运动测试（ET）包括心血管监测下的渐进性运动激发。运动耐力通过工作量来估计。心肺运动测试（CPX）是一种非侵入性的通气气体交换测量方法，可更准确地量化心肺适应性（CRF）。在 ET 中，工作量通常是逐步增加的，而在 CPX 中则是连续（斜坡）增加的。我们的目的是检查结果的可比性。32 名健康志愿者（17 名女性/15 名男性，年龄 26.8±6.1 岁，BMI 24.5±3.0）在自行车测力计上进行运动测试，直至达到最大体力衰竭；使用斜坡方案（CPX）和 2-7 天后，采用逐步增加工作量的方法（ET）。我们比较了两种方法在最大工作量、心率为 150 和 170 次/分时（PWC150 和 PWC170）以及运动持续时间下的身体工作能力。我们发现最大心率（CPX：177.1±11.7/min 与 ET：178.5±11.2/min）或最大工作量（CPX：219.8±50.6 与 ET：209.4±42.5）均无统计学差异。CPX 时 PWC150 和 PWC150/kg 高于 ET（156.6±51 与 146.4±42.3，p<0.001 和 2.1±0.5 与 1.9±0.4，分别，p<0.001）。运动持续时间几乎相等（12.1 与 11.3 分钟）。我们得出的结论是，CPX 的整体身体表现更高。由于结果相似，我们建议 CPX：在性能评估中，功率和其他参数直接确定，插值已过时。
