How adrenaline gives you strength during combat

We've all read stories online about its potency and we've seen the Hollywood renditions of scientists synthesizing it to great effect. In the stories and movies, people experience unbelievable spurts of strength during crazy times because of this epic excretion. We're talking about adrenaline. During exposure to extreme pressure, the human body can produce the valuable hormone, also called "epinephrine," via the adrenal glands. which are located above the kidneys.

These bouts of hysterical strength all start when your body initiates robust activity. The glands release adrenaline into the bloodstream, causing muscles to surge with oxygen. This massive influx of oxygen sparks the human body with incredible energy and near super-human endurance.

This strength has been known to enable humans to lift several hundred pounds at a moment's notice. After oxygen-enriched blood fills the flexing muscles, the blood must return to the lungs to become re-oxygenated — which causes us to breathe faster.

Although we have this stored energy just waiting to escape, our bodies protect us from using it until an extreme event presents itself. This way, we avoid tearing muscle fibers and sustaining other physical injuries caused by intense physicality.

Now, during these massive rushes of adrenaline, the release of endorphins desensitizes our pain receptors. This makes sense of all those stories we've heard about soldiers who have been shot and don't recognize the initial threat.

The University of Tokyo studied the effects of how strong one person could become as the adrenaline secretions pump through their veins. As a grip strength test began, university scientists fired a pistol in the sky. After the sound echoed, the strength of people being tested increased by roughly 10 percent — that's a lot of strength gained in a short time.

It's not comic-book-superhuman strong, but it's pretty amazing.
