How does adrenaline physically give you more strength?

536 views

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!

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.

So imagine your hormones are a guy adjusting knobs in a reactor that powers a machine, deciding where power will go. He looks out the window and sees theres a problem, like work stress or an argument waiting to happen, so he sets the knob a little higher to give the energy to get shit done. This makes your heart beat a bit faster and makes you jittery.
When Things calm back down he sets the power back to normal and the reactor cools off.

When the threat is big and needs a lot of power, the guy ignors the screaming red alarms (pain) and turns that reactor to 100 percent. The reactor can manage it but the machines aren’t prepped for it. So they work with Max power for a while but can get damaged in the process.

Strongman and Olympic lifters aren’t as big as bodybuilders, but are usually much more powerful because they train to use their bodies closer to that 100 percent. But the human body is a strange thing, we’re strong enough to seriously hurt ourselves.
So it’s that reactor guys job to see that the reactor doesn’t always run at full temp
