ADRANALINE:-
This is a 'Fight-Fight' hormone or survival hormone.
when human encounter any danger or threat
we have two options: fight off the predator, or run for the hills.
Each of these responses requires muscle strength.
When our amygdala senses danger, it reaches out to the hypothalamus,  Adrenaline then triggers the physiological changes our body will need to attack, defend, or run away.  
Even before we react, or choose a course of action, our heart is already rushing oxygenated blood to our muscles, so we’ll be ready.
