The Running Doc at Runners World just posted on some conclusions made after the International Marathon Medical Directors Association was reviewing cases of successful recussitations at different races. They were able to interview these runners after they recovered and discovered some similar behaviors between them, specifically high amount of caffeine consumed before and during the race. One was a 32 year old male who had injested 2 energy drinks, a starbucks coffee, and 2 energy gels! Caffeine is a stimulant and has also been shown to decrease coronary blood flow while marathoning. With these energy drinks and gels with caffeine, the total mg of caffeine sure adds up pretty quickly, especially when you add in a morning coffee or big gulp! The Running Doc recommends limiting caffeine intake to less than 200mg on race morning (equal to two cups of coffee). This may be the missing piece of the puzzle to why these young people with healthy arteries are dropping at races.
Still raining out here!
