I have found that on days when I have an indordinately high caffeine intake (like 2x normal) that my heart rate, when riding, can be significantly higher at a specific output level.

I really only see this on the rollers where I am watching speed, cadence and HR constantly.

So, obviously this sucks if youre trying to maintain a HR range of some sort, but what i really want to know is how do high doses of caffeine effect power output? What happens when the heart rate goes up?
