Supports muscle pump theory for venous return; leaves open translation from canine models to human exercise physiology.
Does muscle contraction reduce the time constant of venous drainage in isolated dog gastrocnemius muscle?
Muscle contractions reduce the time constant of venous drainage, supporting the muscle pump theory for increased venous return during exercise.
