I take an ECA at 3:30 p.m and work out around 4:15 to 4:30 p.m.

funny I was just researching that a couple weeks ago. Heres what I found
In athletics three theories have been presented that support caffeine’s use in athletics. The first theory focuses on caffeine’s ability to cause the body to burn more fat and fewer carbohydrates. Glycogen is the principle fuel for muscles, but fat is the most abundant resource that the body uses for energy. Caffeine enters the body and forces the working muscles to utilize as much fat as possible. This delays the immediate depletion of glycogen. Studies show that in the first fifteen minutes of exercise caffeine has the potential to reduce the loss of glycogen by fifty percent. When this happens, the saved glycogen can be used for the remainder of the workout where normally it would be entirely depleted. (http://www.rice.edu/~jenky/sports/caffeine.html)
However, a study involving 9 trained athletes set out to provide proof of caffeine’s ability to work as an ergogenic aid before and during the workout. “In this study involving a 2 hour cycle endurance test, Ivey et al. (1979) found that 250mg of caffeine 1hour before the test and another 250mg total divided in doses every 15 minutes during the test led to higher work output throughout the test” (Dews, p.89) This study resulted in a 7 percent average increase in total output among the athletes. By consuming caffeine during high endurance activities, it is possible to increase the total output.
The second theory deals with the prospect of caffeine enhancing the athlete’s mental focus. Caffeine has been proven to be a recognized stimulant to the central nervous system. By slowing substances used to stop neuronal firing, caffeine can quicken reactions and increase mental awareness. And finally, caffeine may have the ability to strengthen muscle contractions. By transferring calcium, sodium, and potassium in the cells, membrane permeability increases. This in turn results in more powerful muscle contractions. Scientist Gene Spiller has performed many studies in order to confirm this belief. “In a double blind, placebo controlled experiment where caffeine was isolated, caffeine was found to increase muscular force output at low frequencies of electrical stimulation (10 to 50Hz). There was no significant change at higher frequencies of electrical stimulation like 100Hz” (Spiller, 1998). This reflects the belief that caffeine has the ability to create more forceful muscle contractions. Once again, all three of these theories are subject to many different factors, and the precise process by which caffeine affects the body is unknown. (http://www.athleta.com/articles/caffeine.cfm)

i do,coffee,tea or redbull........
I ussualy take an ECA 4:30, workout 5:30 the only problem sometimes is that it keeps me awake a little, and makes me grumpy after I get home from the gym.
somedays when I am feeling special, I have a double espresso!Although coffee, or espesso seems to dehydrate me faster during the workout, then I tend to feel bloated from drinking too much water.

paperbolix said:
Does coffee have any adverse effects on creatine?
I usually down a cup or two pre-worout, or as paperbolix does. I drink coffee before I drink coffee.
But as with the creatine I usually wait 1/2 hr before taking the creatine, does it really matter?

I was given advice from a very sucessful old-school powerlifter(were talking late 70's early 80's lifter) that caffeine should be avoided cause it interferes with the metabolism of both carbohydrates and protein. I still drink coffee now and then but from this advice I always avoid caffeine on those "heavy" training days(80%+ of max).
