Cardiac output during submaximal and maximal work
Abstract
In the present study oxygen uptake, cardiac output, stroke volume (dye-dilution technique) and oxygen content of arterial blood were determined in 11 women and 12 men, 20–31 years of age, at rest, and when performing submaximal and maximal work. At rest plasma volume (T-1824) and heart volume were determined. Sitting on the bicycle ergometer the stroke volume was 40–90% (mean 63%) of the maximum attained during exercise. Maximal stroke volume was essentially reached at a workload with an oxygen uptake of about 40% of the maximum and a heart rate about 110. No tendency to a decrease in stroke volume was noticed when maximal work was performed. The variation in stroke volume was ±4% during exercise in the range from 40 to 100% of the individual's aerobic work capacity. The maximal cardiac output was 18.5 liters/min for women and 24.1 liters for men. The correlation between heart volume on one side and maximal stroke volume and cardiac output on the other side was high and the expected one from the dimension of the individual. On submaximal as well as maximal exercise the women had a higher cardiac output per liter oxygen uptake than the men, and this can be explained by the lower concentration of hemoglobin in the women's blood. cardiac function during exercise; cardiac output stroke volume; cardiac output and arterial O2 content Submitted on October 3, 1963

“En effet, quelques études ont montré qu’au cours d’une épreuve d’effort incrémentale, le VES de l’athlète augmentait jusqu’à VO2max (Ferguson et al. 2001; Krip et al. 1997; Warburton et al. 2002; Zhou et al. 2001; Gledhill, Cox, et Jamnik 1994; ASTRAND et al. 1964; Ekblom et al. 1968) (Figure 29).”

“Accordingly, the continuous SV increase during low levels of exercise, from rest up to 40%–50% of maximal oxygen uptake (V ̇O 2max [77]), is established mainly through an increase in LV filling (end-diastolic volume) and to a lesser extent by enhanced contractility (i.e., reduced end-systolic…”

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.
