Could subdural hematoma be caused from lifting weights?

Answer 1

It is very unlikely (I would say impossible... but everything is possible). If you are lifting a heavy weight and tensing the muscles in the head, you would pass out long before the strain could pop a blood vessel.

Actually that is entirely incorrect it is very possible to cause a hematoma while lifting heavy weights; if the muscles are not prepped for an isotonic contraction and the lift is attempted or even completed at a high weight then the capillary beds can rupture quite easily. One of the worst exercises to cause this are deadlifts, as the lifter begins to fatigue his form can very easily be compromised and if the weight is simply "snatched up" or pulled up without proper prepartion and technique the lifter risks blowing out capillary beds around the distal head of the tricep. I know this from experience, as I am now healing from a hematoma caused by improper form during dead lifts. My anatomy professor who is also a transplant specialist explained how the damage was caused by improper form.
