Suppose you're a trained fighter. You get in a fight with some guy off the street who's super pissed and wants nothing more than to kick your ass. Overall, would your opponents adrenaline rush hurt or help his performance? What if he was also a trained fighter?

Hurts it, unless he does a good amount of damage right away. Adrenaline is only yor friend for a few minutes then he is a monkey in your back.
helps... adrenaline can make you superhuman
It would likely tire him out much quicker... so instead of the usual 30 second gas tank that a streetfighter has, he might last 15.
