These are probably the most laughable products ever promoted.
Don't be fooled by the new wave of "Oxygenated" water products that claim to increase performance, endurance and other various benifits.


MAYBE IF YOU ARE A FISH!
There is NO scientific evidence to show that drinking oxygen will make even the slightest difference to blood oxygen levels.


Take a deep breath and you will get a much greater effect.

Super-Oxygenated Water Is Latest Sports Scam
4-13-98
University Park, Pa. -- Recent hype by a company that its "super-oxygenated" water can boost athletic performance is just one more scam aimed at a gullible audience, says the April issue of the Penn State Sports Medicine Newsletter.


Company literature touts the benefits of a certain "oxygen-enhanced" sports drink, which allegedly contains seven times more oxygen than tap water. However, the study on which the company's claims are based has not been subject to peer review or published in a scientific journal.


"This is a case of pure fraud without a physiologic foundation," says Howard G. Knuttgen, Ph.D., newsletter editor-in-chief and professor emeritus of kinesiology at Penn State. "Very little oxygen can be forced into water under pressure -- less than that contained in a single breath.

"Most of the oxygen in the water would escape into the atmosphere when you open the container. Additional oxygen would be absorbed into the cells of intestinal walls. All of this would happen before any oxygen would reach the blood, much less the muscles."

The exchange of gases that allows the body to take in and utilize oxygen is a function of the respiratory, not the digestive system. Thus, any intake of so-called super-oxygenated water would be of no use in improving athletic prowess, he says.


Knuttgen has some simple advice about super-oxygenated water: "Save your money." He also questions the value of breathing pure oxygen from a canister, a practice followed by some athletes, usually football players.


"Any boost in performance from breathing pure oxygen would have to occur within seconds," says the researcher. "By the time a player who inhales oxygen on the sideline gets into the game, any benefits would be lost. A distance runner, for instance, would have to carry the oxygen canister at all times to get any kind of positive effect. That would be impractical, even counterproductive."
