本研究的目的是测试一种新的便携式肺量计-遥测装置（Oxycon移动的（（R）在广泛的运动强度范围内与精确的固定装置（Oxycon Pro（（R）的准确性。因此，15名经过耐力训练的受试者（VO（2 peak）：58.8 ± 5.2ml（.）最小值（-1.）kg（-1））在两种不同的情况下进行递增运动试验和耐力运动试验。气体交换变量同时测量两个功率肺活量装置。为此，设计了一种特殊的面罩，允许同时使用两种设备进行呼吸气体采样。与Oxycon Pro（（R））相比，Oxycon移动的（（R））作为准确的参考系统，在递增运动试验期间，在200和250 W下的VO（2）值显著较低。对于VCO（2），未发现显著差异，尽管Oxycon移动的（（R））似乎系统性地测量了更高的值。关于RER，Oxycon移动的（（R））在所有测试工作负载下均显示出显著更高的值。因此，我们不建议将Oxycon移动的（（R））收集的气体交换变量与在实验室条件下通过准确的参考系统（如Oxycon Pro（（R）测量的数据进行比较。此外，从Oxycon移动的（（R））测量的数据外推不同运动持续时间和强度期间的底物利用信息似乎不合适。
The purpose of this study was to test the accuracy of a new portable spirometric-telemetric device (Oxycon Mobile((R))) over a wide range of exercise intensities against an accurate stationary apparatus (Oxycon Pro((R))). Therefore, fifteen endurance-trained subjects (VO(2peak): 58.8 +/- 5.2ml(.)min(-1.)kg(-1)) performed an incremental as well as an endurance exercise test on two different occasions. Gas exchange variables were measured by the two ergo-spirometric devices simultaneously. For this purpose, a special face mask was designed which allowed respiratory gas sampling with both devices at exactly the same time. Compared to the Oxycon Pro((R)) as an accurate reference system, the Oxycon Mobile((R)) showed significantly lower values for VO(2) at 200 and 250 W during the incremental exercise test. For VCO(2) no significant differences were found although the Oxycon Mobile((R)) seemed to systematically measure higher values. With regard to RER the Oxycon Mobile((R)) showed significantly higher values at all workloads tested. We therefore dissuade from comparing gas exchange variables collected by the Oxycon Mobile((R)) with data measured under laboratory conditions by an accurate reference system like the Oxycon Pro((R)). Furthermore, the extrapolation of information about substrate utilization during different exercise durations and intensities from data measured by the Oxycon Mobile((R)) seems inappropriate.
