In theory, that might work. The high pressure during those events causes us to produce adrenaline anyway, how else would athletes be possible to suddenly break their own records during a competition? But although there are effects, it seems like the performance can’t be significantly improved.

This is anecdotal evidence, but I have heard multiple accounts of people in Jiu-Jitsu tournaments who are competing for the first time, and just as their fight starts they get this huge adrenaline dump that stimulates them for a few minutes... and afterwards they crash down and feel completely exhausted and even unfit for their next match.

So, it would seem like too much adrenaline at once topples the balance towards it being draining more than stimulating.

Very interesting post as per usual, @suesa!
