I've seen a claim that bigger persons generally resist g-forces worse than smaller in an undergraduate biology book. However this claim was supported by the argument that blood has to travel a longer way form the head to the heart.
However, I think this is not the only factor that matters. They generally should have a larger heart, but may need to pump more blood, so perhaps this cancels.
- Has it ever been tested whether bigger persons generally resist g-forces better? If so, what were the results?
- If we only take scale factors in considerations, i.e. we take identical persons, but the one is 1.2 times as large as the other in all dimensions, what conclusion will we reach? What factors should we take into consideration?
