Caffeine and workouts

cse01 Posts: 1 Joined: 2005/04/01	2005/04/01, 03:15 PM Has it been your experience that caffeine (2 cups of coffee) before workouts provides a boost in performance/stamina? In moderation, is this practice harmful?

It's also been shown to help release stored body fat so that it can be used as energy. But beware, because caffeine also acts as a diuretic. It speeds urine production and dehydration, which robs your body of the water it needs for cooling. The recommended dosage is 3- 9 mg per kilo of body weight (avg of 2- 6 cups) so sounds like you're safe.

	2005/04/06, 07:31 PM Yes the caffeine before workouts helps especially in endurance exercises...diuretic effects have been overly exaggerated over the years....recent research suggests that the effect is quite mild....but drink plenty of water when you workout...

It has been my experience that many of the people I work out with tell me that there HR elevates past the point that they deem acceptable, and some have reported becoming winded quicker while exercising.
