| | Oxygenated Water and athletic performance | | by: Coach Hale - Fri Jun 04 2010, 07:54AM | Manufacturers of oxygenated water often claim drinking their product has ergogenic benefits. In a paper first published in the British Journal of Sports Medicine in July of 2006, Piantadosi (professor of medicine and director of the Center for Hyperbaric Medicine and Environmental Physiology, Duke University Medical Center) stated, “Ergogenic claims for oxygenated water cannot be taken seriously.”
Leibetseder and colleagues (2006) investigated the effects of a two-week period of daily O2-water ingestion on aerobic parameters and lactate metabolism in healthy adults. Twenty men (24 ± 2.5 years of age) with comparable aerobic abilities performed four exhaustive bicycle spiroergometric tests. Applying a double-blind crossover study design, ten subjects drank 1.5 liters of highly oxygenated water every day during the two weeks between the initial two tests. The other group consumed 1.5 liters of untreated water from the same spring. After a two-week wash-out period, subjects underwent a second period, consuming the opposite type of water. Spiroergometric parameters and lactate kinetics between both groups at submaximal and maximal levels were analyzed. Results showed no significant influence on aerobic parameters or lactate metabolism, neither at submaximal nor at maximal levels. The researchers concluded that the consumption of oxygenated water does not enhance aerobic performance or lactate kinetics in standardized laboratory testing.
Claims that drinking oxygenated water offers ergogenic benefits is not supported by evidence.
Btw, testimonials don't count as evidence.
