Abstract
We tested a new portable metabolic system, the Jaeger Oxycon Mobile (OM) at a range of running speeds. Six subjects carried out, in random order, two incremental tests on a treadmill, one of them using the OM, and the other using the Jaeger Oxycon Pro (OP). There are systematic errors in the measurements of oxygen consumption (V[O.sub.2]) and respiratory exchange ratio (RER) with the OM. Production of C[O.sub.2] (VC[O.sub.2]) tends to be overestimated by the OM, although the differences are not significant. Ventilation ([V.sub.E]) showed very similar values in both analyzers. Data of V[O.sub.2] and RER were corrected with a regression equation which ...
