Limitations to maximum oxygen uptake in arms, leg, and combined arm-leg ergometry
Abstract
Our purpose was to study the effect of arm, leg, and combined arm-leg ergometry on the oxygen uptake (Vo2), cardiac output (Q), ventilation, and anaerobic threshold (AT) of three healthy men. At submaximum work intensities, Vo2 was not significantly different in the three tasks, but differences were observed for heart rate, ventilation, and Q. The AT was reached at progressively higher work rates in arm, leg and combined arm-leg ergometry, respectively. The Vo2 max in arm ergometry averaged 68 percent of the Vo2max in leg ergometry and 60 percent of Vo2 max in combined arm-leg ergometry. Two subjects with Vo2max's less than 45 ml/kg-min had a mean Vo2max in combined arm-leg ergometry 19 per cent higher than in leg ergometry. A third subject, with a Vo2max greater than 50 ml/kg-min, showed no change. Differences in Vo2max were primarily due to the differences in Q. Skeletal muscle blood flow appears to be a critical factor in the limitation of Vo2max in arm or leg ergometry.

“However, VO2 max is unlikely to be limited by an inadequate ventilatory response [24], so these negative results are not surprising.”

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.
