Levelling-off of calf blood flow during walking and running, and its relationship to anaerobic threshold.
Open accessAbstract
Calf blood flow (CBF), heart rate (HR), whole-body VO2 were measured in 13 active women (aged 20.8 yrs) while walking or running at various speeds up to near exhaustion. CBF during walking increased linearly in relation to speed in the range 60-100 m/min, and thereafter it levelled off. CBF during running showed a small increase up to 180 m/min, then decreased significantly (p less than 0.01) from 24.51 ml/100 ml calf min to 19.62 ml/100 ml calf/min. VO2 corresponding to peak CBF (BFpeak-VO2) averaged 66.39% VO2-max, which was significantly lower (p less than 0.05) than the anaerobic threshold (AT; 74.48% VO2max) determined using gas exchange parameters. Significant correlation coefficients of 0.695 (p less than 0.01) and 0.708 (p less than 0.01) were obtained between BFpeak-VO2 and AT-VO2, and BFpeak-%VO2max and AT-%VO2max. The magnitude of CBF was not correlated significantly with AT or VO2max. Levelling-off or decrease of CBF at higher speeds, approximately 10% below AT, suggested that an inadequate blood supply will possibly result in mismatching between oxygen delivery and muscle oxygen demand and that this would lead to switching over to anaerobic energy generation.

In the citing paper
“This is further supported by our data indicating that neither C4E nor MED augmented leg blood flow, and thus were not likely to have influenced blood supply and oxygen delivery [ 54 ].”

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.
