Sprinting's effect on neurochemistry page

[Dlt]

I love to sprint. I've spent an hour or two today researching the title of this post looking for any kind of substantial answer. I've come up short. Can anyone answer this for me or at least point me in the right direction?

supposedly raises epinephrine and cortisol

Jack Kruse has mentioned something about this in his blog but I can't remember which post.

Check out how sprinting affects the activity of mitochondrial activity. High intensity training, such as sprints for maximum combustion of glycogen, have a great impact on the mitochondria. It is the mitochondria in cells that burn fat for energy, and sprinting stimulates this activity.

I know all about the mitochondria. Im wondering about brain chemistry. And if sprinting raised epinephrine, that would mean dopamine would have to be raised first. Kinda what I'm thinking about here. Where does dopamine really come into play in short intense exercise? I got majorly addcited to long distance running bc of endorphins and dopamine.

Whoops - my bad. I didn't catch the neuro bit there. AFAIK all exercises rises epinephrine, and HIIT being even more intense than long distance running I would believe HIIT would rise it pretty much too by my guesstimate.

I certainly feel like a million dollar when I have performed a successful HIIT session with with a 8 x 30/60 scheme for instance.
