  • Title: Polycythemia, viscosity and blood flow in working and non-working skeletal muscle in the dog.
    Author: Gustafsson L, Appelgren L, Myrvold HE.
    Journal: Bibl Anat; 1979; (18):56-9. PubMed ID: 496880.
    Abstract:
    The relationship between hematocrit and blood flow in the vasodilated working and non-working skeletal muscle at different perfusion pressures was studied. After acutely induced polycythemia in the flow decreased by 35% in the non-working muscle which was proportional to the increase of viscosity measured in vitro. In the working muscle there was only a small non-significant decrease of flow after polycythemia indicating flow improvement at increased hematocrit by rhythmic muscle contractions.
