Well, I am happy to report that I have been using the Skratch Labs Secret Drink Mix for a week on training rides ... and it is AWESOME!!
Hands down best mix I have used, and I am hooked now and forever on the stuff. My personal favorite being the raspberry.
Now in that article I shared a video of Dr. Lim, and a really neat experiment about hydration in general.
Well right on cue, Dr. Williams of The Science of Soccer Online, posted Heat, Dehydration and Performance, a very worthy read on the topic.
The bottom line, and I quote from the article:
"The bottom line is, keep dehydration at bay by drinking plenty of fluids before and during play. Also, drink after the match. Staying hydrated can improve performance and avoid health problems."
Don't forget, referees are endurance athletes too, and need to abide by this same advice. For my money Skratch Labs has the best stuff around for it.
