To the Editor: Bottled waters described as
"oxygenated" are sold with claims that they confer health benefits. The waters
are advertised to contain 7 to 40 times more oxygen (O2) than ordinary
water and to enhance exercise, with statements such as "enhanced sports performance"1 and "improves cardiovascular and muscle
endurance"2 commonly used. We measured O2 in oxygenated
water and assessed its effect on maximal performance during exercise.
