Default PWO Caffeine - Your thoughts

I just read this article:
http://www.medicalnewstoday.com/articles/113495.php

And then read this synopsis of the data from the study:
http://jap.physiology.org/cgi/conten...t/01121.2007v1

I'm thinking about adding caffeine to my PWO supps...especially on leg day. I can't wait for them to repeat the study with a reasonable amount of caffeine. 8mg per kg of bodyweight is a LOT. Most of the data they present is at a pretty high significance level. I didn't realize the study was done several months ago until I checked the dates.

Does anybody else have an opinion about this?

Interesting. I had heard that caffeine makes blood vessels vasoconstrict. Oh, these medical studies with their varying results. It is worth looking into, I think. I add in some gingseng tea to my PWO stack-since it is high in glucose-which is a carrier substance for creatine-another component of my PWO stack. I have a water bottle that I carry around EVERYWHERE!!! I throw in 2 black tea tea bags. Good source of antioxidants.

That is pretty interesting, but it doesnt mean much for me. Since I lift at night, if I was to do that I'd be up till the next morning.

I'd like to know why this would happen, perhaps because caffiene increases heart rate?

caffeine may increase the activity of several signaling enzymes, including the calcium-dependent protein kinase and protein kinase B (also called Akt), which have roles in muscle glucose uptake during and after exercise.
That was part of the explanation.
