Skeletal muscle pump

It is especially important in increasing venous return to the heart,[1] but may also play a role in arterial blood flow.

The skeletal muscle pump is vital in negating orthostatic intolerance when standing.

To combat this, the muscles involved in standing contract and help to bring venous blood volume to the heart.

Another experiment recently was only able to find evidence that vasodilation, not the skeletal muscle pump, was responsible for maintaining proper pressure and blood return.

Experiments have shown the use of passive leg exercises, where only vasodilation was used, was responsible for increased blood return.
