I routinely (especially in the summer in the Southwest) experience near immediate hypotension after finishing a (running) race. The last time it happened, the medic explained that my legs add significant circulatory capacity— when they’re moving. I now walk around after races until vasoconstriction happens, and I fair much better.
I don’t know enough to corroborate the ram pump theory, but I don’t doubt that there are other mechanisms aiding circulation
- 01100011 7y agoSorry, I was hoping my insertion of the word 'generally' implied that it wasn't the only driver of circulation in all circumstances. Yes, there are check valves in the circulatory system and peripheral muscle contractions contribute as well, but comatose people don't, as far as I know, die because their muscles aren't contracting. The body doesn't seem to require peripheral muscle contractions to circulate blood.
