How does adrenaline physically give you more strength?

Question

We’ve all heard the stories of superhuman strength caused by adrenaline, people picking up cars because somebody was trapped, people ripping doors off cars with their bare hands, etc…

I know it increases your heart rate, dilates blood vessels, and increases breathing. What is it that is actually giving you the strength through your muscles? To be able to lift something 3 or 4 times what you could previously lift? Is there a chemical reaction of enzymes and nutrients or something?

Thanks!

Answer 1

Adrenaline prevents pain response from happening, which allows people to do these extreme feats. When they do these actions they are also ripping muscles and breaking bones, they just don’t feel it at the moment. Humans are very strong animals but the pain response is to prevent us from injuring our bodies.
