Safety and Efficacy of Caffeine in Exercise

Boing Boing has a nice post about caffeine and energy drink use in distance running events, and associated mortality. It's not huge, but it's still worth reading. The best part of it is the actual peer-reviewed references. One shows that marathon runners (highly-trained or recreational) reap a 1% boost in their marathon times by using caffeine; so if you run a 3:30 marathon, now you'll run 3:28. Another shows a similarly modest boost in high-impact exercise, as long as you're not already a caffeine junkie with a developed tolerance.
