[QUOTE=Darryl Shaw;1240589]While I am happy to support any campaign that highlights the risks of over-hydration it must be evidence based if it is to be taken seriously. Therefore, using this childs death to further this campaign before the cause of death has been established is simply indefensible, and I hope 'The Russells' have the decency to either edit their blog or remove that post until after the autopsy results are known.[/QUOTE]

Darryl,

Having spoken to both the Oliver family and Dr. Sandra Godek, the cause of death is clear. Consider that I have access to more information than what you've read in the press.

Reiterating my request to get a copy of the book, if there are any left. Thanks!

Another high school football player, Walker Wilbanks, passed away today from swelling of the brain after collapsing in practice. All signs point to EAHE.

Each death reported that could be overhydration EAHE feels like a sucker punch to the stomach. I hope those connected to the victims will search and learn more about overhydration. How many more will die before good information gets ahead of the problem? I would [I]love[/I] to see Gatorade do an appropriate use campaign like Tylenol or smoking companies have done. Until then, keep expounding, Russels.

[QUOTE] I'm interested in going back to the ACSM/GSSI studies on heat exhaustion, etc. to see why they recommended excessive drinking in the first place.[/QUOTE]

[QUOTE=Christopher Morris;1220965]Dale,
Thank you for those last two posts. The timeline you present is insightful as to who knew what and when. That has clarified why CrossFit HQ wants to take this issue head-on so aggressively.[/QUOTE]

I've had questions about the origin of hydration science since this topic was brought up. In [I]Waterlogged[/I], pages 148-154 summarize the invention of Gatorade from an authoritative source. Though it is claimed Gatorade was born from research, the circumstances do not stand up to scientific scrutiny in the least. The book summarizes: "Dr. Cade's presumption is that the explanation for the success of a college football team can be reduced to a single variable, in this case to the presence of additional electrolytes in their sports drink. In reality, the factors determining success in professional team sports are so complex that they defy analysis." The rise of Gatorade feels less scientific than sports superstition, almost on the level of[URL="http://en.m.wikipedia.org/wiki/Mark_Spitz#Iconic_moustache_during_Olympics"] Mark Spitz's mustache[/URL].

I found both of these articles important on the subject of EAHE:

The Clinical Journal of the American Society of Nephrologists, 2007, "Exercise Associated Hyponatremia", offers a compelling overview of EAHE reaching the damning conclusion that "In many respects, EAH can be viewed as an iatrogenic condition because of the prevailing view that exercising athletes should drink as much fluid as tolerable during a race."
[url]http://cjasn.asnjournals.org/content/2/1/151.full[/url]


From 2004, The British Journal of Sports Medicine, "Weight Changes, Medical Complications, and Performance during an Iron Man Triathlon", demonstrating that "there is no increased risk of heat illness associated with high levels of dehydration, and that high levels of weight loss do not significantly influence performance."

Jacob Levin sent me this hyponatremia story from his time in the Army. One wonders how many other cases of fatal and near-fatal EAHE are yet to be recorded in the literature. A nephrologist told me yesterday that everyone knows at least one person who's suffered from EAHE. The full number of both incidents and fatalities may be many times what Noakes found in Waterlogged.
[I]
"In 2011, I was an IET soldier at Fort Benning, Georgia. On a twelve-mile road march, in order to prevent becoming a 'heat casualty,' I consumed roughly eight liters of water. I note that this is an estimate, based on how much water my Camelbak could store. I'd also been drinking water throughout the day to pre-hydrate for the march.

At roughly Mile 10, I became disoriented, confused, dizzy, and nauseated. Thanks to the excellence of my cadre, I was identified and set aside and an ambulance was called.

To make a long story short, when I was delivered to the ER, my core temperature was slightly elevated (101), but not enough to cause my symptoms. I was, however, severely overhydrated.

If the US Army is supposed to be issuing 'maximums' rather than 'minimums'" then my otherwise-excellent trainers failed me. We routinely were told to drain canteens and then turn them upside down to prove we'd drank it all ...

I almost died, and I know of other guys (again, anecdotal rather than hard-fact) who were hospitalized with almost identical symptoms."[/I]

I've been patiently waiting and just settling into passive monitoring of this process to ask for an accounting. Maybe I am just restless in the moment.

Maybe I am tired now as specifically Football Season is upon us; youth, collegiate, professional, and I'm not altogether satisfied any real action or change is taking place. My son and daughter (likely yours as well) have started lacrosse season and I see it. 'Hydrate Hydrate Hydrate.'

How many more people are going to die before the scare becomes realized real? Because it is real.

It's been since January 1st that I've refused all forms of Sports Drinks and specifically Gatorade. I've made it through the heat of the year and accomplished a few pretty lofty physical events; just fine I might add. I do my best to keep it out of the hands of my children and loved ones. I educate my 'people around me' the best I can as well.

We proffer proud chests and words over social media and leverage social pressures to get informed. But Beverage Powders and the 'Hydrate Mantra' exist no less than they did 8 months ago. Much worse - the common misconceptions and 'understanding' of hydration science is still being taught in our military and athletic communities.

If the ALS Ice Bucket Challenge can raise 110$ million (94 in the last <2 months) how can we not create at least a national petition or public boycott on products?

40,000+ views and 206 comments since Feb 19th. If Gatorade sales are up this quarter, we are failing.

I'm in. This is maybe a [U]Call for Action[/U] before we become guilty of the reluctance to act and the 'powder keg kicking' that the ACSM Guidelines have done over the past decade and (no)change.

I may have missed something but are people really thinking Gatorade is killing kids. Or is there more to this. I know over hydration is a real thing but is there a difference if it's Gatorade or water?

Understand that I am late to this party...but I bounced over here from the Message Board discussion of this from 140907.

I would love a copy of the book if there are any still available. Thanks in advance!

[I][COLOR="Blue"]on the list! ~Lynne[/COLOR][/I]

Re: Exercise Associated Hyponatremic Encephalopathy, Gatorade and the ACSM
 
Mike,

If I understand the issue correctly, it's not necessarily that over-use of Gatorade is more dangerous than overhydration in general. The issue is that Gatorade has, for a number of years, deliberately downplayed and outright lied about the risks of EAHE in order to sell their product.

I'm not an expert on the subject, so take my explanation with a grain of salt.
