From the International Journal of Sport Nutrition and Exercise Metabolism and the Department of Kinesiology at Indiana University:
Karp JR, Johnston JD, Tecklenburg S, et. al., Chocolate milk as a post-exercise recovery aid, 2006; 16, 78-91
Nutshell: You need glycogen stored in your liver to perform well in endurance exercise. You resynthesize glycogen between training sessions most rapidly if you consume carbohydrates within 30 minutes after exercise, and adding protein to the mix will improve endurance performance compared to drinks with carbos alone.
This team of investigators hypothesized that the time to exhaustion (TTE) during a second bout of exercise after a first that depleted glycogen would be longer if the subjects drank chocolate milk (CM) {low-fat from Kroger's I kid you not} as compared to those who drank simple fluid replacement (FR) {aka Gatordade}. In addition, they figured that the TTE for CM drinkers would be equivalent to the TTE for those who drank carbohydrate replacement (CR) drinks {something called Endurox R4}
BREAKING AWAY??
SO--- they got 9 male cyclists from IU's cycling team and ran them thru 4 spin-classes from hell (er, testing sessions) comprised of 2 bouts of cycling to exhaustion separated by 4 hours of recovery. During those 4 hours they consumed equivalent amounts of either CM, Gatorade (FR), or Endurox (CR). After all the abuse, the subjects cycled 49% longer after CM as compared to Endurox, and 54% longer after Gatorade as compared to Endurox. BUT there was no statistically significant difference between CM and Gatorade......
BACK TO DRINKING THE KOOL-AID???
The investigators, who by the way were supported by the Dairy Council for this work, state as their conclusion, "results of the study suggest that chocolate milk, with its high carbohydrate and protein content, may be considered an effective alternative to commercial fluid replacement and carbohydrate replacement for recovery from exhausting glycogen-depleting exercise."
So, while chocolate milk may be very "sexy", at least in this study, it didn't seem to provide any advantage over Gatorade..........

I always replace my fluids with beer... but then I'm not looking to be the next Mr. Universe or anything special... just a normal everyday guy.
In fact... 1.5 hours until BEER TIME!!
I do plenty of biking in hot weather. Why do I have a feeling that the chocolate "cottage cheese" forming in my stomach after drinking CM will not end up in my liver?
T9,
"Science Friday"??? what's next? "Eat your vegetables Wednesday"? "Wash behind your ears Monday"?
my guess is we're not going to see much in the way of wayward cheerleaders or school mascot fetished porn stars, either, are we?
that said, the comparison of sports drinks WAS interesting, so i suppose it didn't hurt me to actually learn something on a Friday.
all kidding aside, wonderful of you to take up the chore and provide this forum. maybe we can talk Yost into providing the occassional "guest" post? i'll try to forward any funny/interesting tosu "items" that come my way.
thanks again.
Chocolate milk does have one major advantage over gatorade: nowhere in its past does it have an association with the University of Florida. I think that's (Tim Tebow) reason enough to (Urban Meyer) boycott Gatorade (Gary Danielson lobbying for Florida on CBS) in favor of chocolate milk.
Also, I think a future Science Friday should discuss the difference between eye black grease and eye black stickers.
Sgt. Wolverine...
...and black eyes (does it have the same effect?)
SiC--
no, only football related science allowed. I like Sgt's idea of eye grease. I have some other ideas floating about as well.
and, there probably won't be naked co-eds from me, but I'm hoping to find a "healing picture" or two.
I have one in mind already---David Beckham's new underwear ad
( SIGH ) but I know that that must be countered with an Erin Andrews or two (twenty?)
was also thinking about a "Know Your Coach" feature as we get revved up over the summer. I'm happy for others to provide wit/wisdom as well!! :-)
glad that the regulars are here. I'll try not to let you guys down.
So I have a question... does it have to be chocolate-chocolate milk, or can I down white-chocolate milk??
They have a chocolate energy drink here from Emmi... which seems to be milk based, but I've never read the package...
Title IX... am excited to read your posts... good luck.
ok... I'm an idiot... forgot it is called "Energy Milk" from Emmi.... I blame this on a lot of work and sangria earlier in the week....
T9,
one question before the weekend- are you going to set up an email address related to the site?
something like "spawnofmzone at gmail". etc., ?
might make it easier for folks to send ideas/posts/news items w/out you actually having your personal email clogged up/subject to bombardment by hostile other fans...
T9,
you could give advice on how vodka is a better tailgating adult beverage over beer--due to the fact you wont have to go to the bathroom as much during the game...also vodka has no smell on your breath...
but then again beer bong fridays does have its merit!
thx SiC! done, as you have written
Hey just sent you a fab contribution as you say. One questions tho- is it "site address" @ gmail or is it "site name" @ gmail. You gotta remember, some of us, er....not so bright!
Site name -- the subdomain.
