How much blood does Shaquilleo Neal contain

[WillemSverige]

Hey scienceforum physiologists

 

Yesterday we got into a discussion about sports and physiology, among which why does Shaquille O'Neal shoot such poor free shots.

We considered that the shear weight of his arms is making coordination in such a fine tuned movement difficult, combines with the length of his nerves.

And other mechanics seem to play a role too, his hands seem simply too big to hold the ball precisely.

But how about his physiology?

How much blood does such a huge guy's body contain? 147 kg, 2.17 meter (I live in Sweden).

Considering he is a well trained athlete. And how much would it be if he were a fat guy, not trained at all.

Thnx for helping
