Animal data link higher contraction frequency to greater contractile-phase venous flow; hypothesis-generating for human exercise hemodynamics.
Does increasing muscle contraction frequency increase the contribution of the contractile phase to mean venous blood flow in isolated canine skeletal muscle?
Increasing muscle contraction frequency increases the contribution of the contractile phase to mean venous blood flow due to increased blood expulsion per contraction and decreased time in the noncontractile phase.
