So i was reading cody lundins book 98.7 degrees and in it he states that the best way to re-hydrate and keep yourself hydrated is with carbonated water. This is the first time that i have heard this. My current use for hard labor outside is a 2:1 mix of water and gatorade. So what say you outdoors collective? Should i try seltzer water the next time im hung-over or go for a run?

I'd like to see the research he based that on. 'Till I do I'm retaining a position that he doesn't have a clue what he is on about. I can't find any evidence for that at all. As usual I'm open to being knocked down. If someone has the relevant evidence I will yield.
 
I don't have the book with me, but I thought the carbonation would expedite hydration by opening the 'valve' to the intestines, not necessarily hydrate you anybetter than water ~ again, just expedite.

Yes, THats the supossed science behind it. i just want to know if it actually works, obviously its not going to rehydrate you as quick as an I.V
 
I have a book somewhere around here, probably "VO2 Max" that talks about Alka-Seltzer for athletes.
I believe soda water contains additional minerals, including sodium and potassium, though I don't know how much(or little).
 
My cross country instructed us NOT to be drinking seltzer water during workouts, because it doesn't offer any benefits over regular water, costs more, and does something funky with your inner workings.
 
I think Lundin's point is that I rehydrates you fast in an urgency situation. So no, it's not the best way to keep yourself hydrated.
 
I read some where that O-2 does help with hangovers so I guess that seltzer would assist the recovery from too much libation , seltzer makes me burp . lol
 
Yeah, it's just CO2. If you drink a lot of it, and then engage in heavy exercise, the excess carbon dioxide buildup in your stomach could make you pretty uncomfortable. Either back up or out the back, if you follow.

This sounds pretty much like junk science. I can't fathom any physiological benefit to seltzer over regular water. In fact, I can think of two reasons against: (1) seltzer requires pressurized bottles, which are usually glass and therefore heavier than regular bottles, and (2) your gastrointestinal system will technically have one more thing to do than simply absorb water...it has to deal with the carbonation. Not that that's a big deal, but why make your gut work harder?

Just goes to show that there's a lot of loopy thinking even in this "prove it or die" business.

Ok, that was "Max O2", and sodium bicarbonate(equivalent to 10 or more Alka-Seltzers) was for buffering against the accumulation of lactic acid to effectively raise the lactic threshold in short-term high intensity athletic events like a 800m race.
Semi-interesting, but nothing to do with hydrating, unless you count the negative effects from acting like a laxative a few hours after the competition.

If you have to run up a mountain really fast, and are constipated, it might help you out on both counts, though:D
 
I also remembered that the CO2 that gets in your blood decreases the amount of oxygen that can be transported.
 
I saw this so I pulled out my Anatomy & Physiology Books. The stomach's internal pressure remains the same until 1.5L of food is consumed. At this point the pressure begins to increase. The stomach under normal conditions will completely empty in 4 hours. The rate of emptying can be affected by the amount of food and/or liquid in the stomach. Large meals and/or high liquid content will increase the rate of emptying.

Now I could be wrong but I think the reasoning behind the carbonated beverages being of assistance is that the carbonation causes the pressure to rise and this tricks the stomach into thinking it has a large watery meal in it. This results in an increase in emptying rate is what allows the water to get into the intestinal tract quicker than it would under normal conditions. Hopefully somebody with more knowledge can confirm or refute my theory.

Now as for the issue of the CO2. While it is true that CO2 (and CO) does interfere with the blood's ability to transport oxygen because it displaces oxygen on the hemoglobin it is not valid in this case. The cells of our body ride themselves of CO2 (which is a by-product of cellular respiration) so the cells of the intestinal system will not pull any CO2 present in the digestive tract into themselves. Even if they did the digestive system ties into our circulatory system on the veinous side of the systemic system and this blood is on its way to the lungs for gas exchange. So any CO2 that did possible get into you system via digestion is going have no effect as blood your is already full of by-product CO2 on its way to the lungs for gas exchange.
 
Where I grew up, seltzer was a major food group.
In fact, I'm drinking lemon lime seltzer tonight.

When I was very young, I thought seltzer was a necessity, but then my brother taught me how to burp by swallowing air first, so I didn't need seltzer to be able to burp at will any more.

I was really proud of him for teaching me that. He's my little brother, and it was the first thing he taught me.
 
If it was a good idea, wouldn't we be see football players, and track & field athletes using it?
 
Hydration begins with carbohydrates and water. The human body has to store 2.7 grams of water for every 1 gram of glycogen stored. The most important factor of a sports drink is the glycemic response of the drink and the amount of water ingested. Athletes need 85-95 ounces of extra water available for a strenuous athletic event. That's not water ingested, but body stores of available water from carbohydrate hydration and water loading.
Your water or sports drink should be ingested cold. Water below 50 degrees F (10 degrees C) is absorbed faster than room temperature water. Do not use carbonated water, soft drinks, sodas or other carbonated beverages when hydrating or during exercise. Hydration guidelines apply to athletes that sweat profusely during an athletic event or athletes that partake in heavy exercise or endurance events.

another good article

http://www.pponline.co.uk/encyc/0824.htm

and I have NEVER seen an article showing drinking Carbonated water(or any beverage) was absorbed faster than non carbonated

Well, what it used to be was Gatorade & Pedialyte. I don't know if that's what is still being used. The combination of the two makes for a better vitamin, mineral & electrolyte concoction of rehydration and aids absorption into the system quicker.
