Can oxygenated water add oxygen to the blood? It's doubtful. Blood carries the majority of oxygen in a form that is bound to hemoglobin and only a small portion of oxygen travels as gas dissolved in the blood. Since 98 percent of arterial hemoglobin is saturated, any oxygen the gut adds after drinking (according to manufacturers' claims) must travel dissolved in the blood.
However, the small amount of oxygen already present in the blood makes it very difficult for more oxygen to force its way in. Unless exposure to a hyperbaric chamber, for example, increases atmospheric pressure, blood cannot carry more oxygen.
This is further reinforced by the results of an unpublished study conducted by Texas Women's University in Denton, Texas. There, researchers did not see a change in oxygen saturation using pulse oximetry. If the waters truly delivered on their claims—and added more oxygen to the system—researchers would have seen an increase of oxygen in the blood.
This leads us to believe:
There's very little oxygen in the water.
The intestinal tract does not absorb the oxygen.
It's difficult to detect the small amount, if any, of the oxygen that is absorbed by the gut.
Confirmation: No Benefit
Researchers from the University of Wisconsin at LaCrosse recently did a comparison study of super-oxygenated water and unoxygenated bottled water. They shared their findings at the American College of Sports Medicine meetings in June, 2002.
In the study, subjects drank 500 mL (17 oz) of either fluid. Fifteen minutes later, researchers measured subjects':
Maximum heart rates
Maximal oxygen consumption ("max VO2")
Duration of time to max VO2
The max tests were repeated shortly thereafter on the same day to see if either beverage enhanced recovery. Their findings? That there's no difference between beverages for performance, maximum heart rates, markers of recovery (blood lactic acid and ratings of perceived exertion) or performance after recovery.
Summary
The bottom line is that oxygenated manufacturers' claims have lots of theory and very little substance. Human physiology and science show us that oxygenated water won't elevate oxygen levels in the blood or muscle. While claims are enticing, they don't hold up when it comes to improving muscle metabolism and performance.

Z tego co wiem właśnie zwiększenie tlenu w komórkach jest dosyc pomocne. Jedna osoba tez mi mowila że nie powinno się dostarczać tlenu ponad to co wdychamy z powietrza. Wiem że niektórzy sportowcy odwiedzają bary tlenowe. Czy jest to dobre dla organizmu? A suplemacja aminokwasami, ktore nie są niezbędnymi dla organizmu? Nie ma co tak od razu tego odrzucać.

To przeciez zupełnie co innego
Tak samo jak bary tlenowe, zresztą 'skutki uboczne' barow to:
-wzrost cisnienia tętniczego
-mozliwosc wystapienia nadcisnienia płucnego
-"dotlenienie" przyspiesza procesy starzenia i moze powodowac powstawanie procesow nowotworowcych w skutek nadmiaru wolnych rodnikow, bo tlen własnie jest ich 'doskonałym' nosicielem.
