Adrenaline dump can be experienced in different ways, but from my personal experience, and from talking to other fighters its usually like this:
The first minute or even 30 sec of the fight, you feel ok with your energy, then all of the sudden you feel like fighting in a swamp, or under water. Your mind is not clear, you can't thing about game plan, strategies. You just kind of react to whats happening. You feel slow, legs heavy. You have tunnel vision, but not the good kind. You don't hear your coach anymore... Something between been dizzy from a blow to the head, and been dead tired like its the end of the 5th round.
But personally i dint feel more pain in that condition, but i don't know about others.
It's not something you can control once it started, but it's something you can prepare to avoid. You also must find what may trigger it, and the problem is that most of the times you got to experienced once to understand what caused it.
It may be caused from over excitement, nervousness in front of a big crowd, nervousness if you know that your opponent is really good etc...
Mine was when i fought in front a very big crowd for the first time. I was used to fight in front of an audience, but not something that big. The thing is, I dint felt specially stressed but i dint do a good job to mentally prepare my self... I was with a new corner, new coach. Also it was a tournament, so you dint knew when you will be fighting, so i was alternating warm-ups and relaxing. Usually i got to make my self enter the zone...yeah i know it sounds stupid, but it's something that works for me. I got to make my self be serious about it, not treat the fight like a sparring session. And for that, i kinda need to be in a bad mood, i need to listen to some music that have that effect, concentrate on some thoughts, that gets me there... But that day i dint do that.
Another factor was probably that my first fight got cancelled, my opponent dint make weight. So i had a lot of time just waiting, while my second opponent was already in fight mode. (to be clear, i would have probably lost that fight in any case, he was just better. But i dint enjoy it, i dint fight like a normally do, i dint make him work hard for it)
I read somewhere that a gym, but i don't remember which one, prepare their new fighters by doing rehearsal of the walk out. With the music, some friends and members for the crowd, the corner following all the way to the ring, the presentation etc...
But adrenaline dump its not to be confused with just been nervous. Usually we are all nervous before the fight, and even maybe for the first actions, but then it goes away. Adrenaline dump is the opposite... You feel good at first because your body is full of adrenaline, but suddenly it disappears leaving you without energy...
It's something you may never have. But the more experience you get, the better you mentally prepare your self, it also diminish the chances to have one...
Anyway, that's my personal experience with it. I think some people had adrenaline dumps later inside the fight, and probably others experienced differently and for other reasons...
