Non-violent high-adrenaline activities

So I came across this article today where the military has created a program to help combat vets deal with PTS by providing them with non-violent high-adrenaline activities.

This got me thinking to the notion of the "higher consciousness thru harder contact" motto.  Do people here have any non-violent types of activities they practice routinely to help them become more self-aware of how they respond/react in a high adrenaline state (i.e. skydiving, bungee jumping, getting married etc.)?  If so, has it helped improve focus during sparring/gatherings?
