A Comparison of VO2 Measurement Obtained by a Physiological Monitoring Device and the Cosmed Quark CPET
Open accessAbstract
The purpose of this study was to compare the results of measurements of VO2 as obtained by the Zephyr Bioharness (ZB) and the Cosmed Quark CPET Metabolic cart (CM). Both ZB and CM have been proven reliable by previous research. The ZB is portable and offers many practical advantages over CM, which requires greater expertise and expense, and tests must be completed in a laboratory setting. Aerobic capacity was assessed in a sample of college students (n=33). Subjects performed a maximal test using a treadmill protocol. Mean Ventilation (VE), mean heart rates (HR), respiratory exchange ratios (RER), and aerobic capacity (VO2) were similar using both the ZB and the CM, with no significant differences observed. Because data varied very little, both methods are comparable, which indicates ZB is a practical solution for monitoring physiological variables outside of a laboratory setting.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
