Super-oxygenated water fails the test.
Claims of higher energy, improved mental awareness and concentration, and increased athletic performance failed to materialize in studies of super-oxygenated water compared to tap water. Manufacturers base their claims on the assumption that water pumped up with extra oxygen (up to 10 times the oxygen content of tap water) will supply muscles and brain tissue with more oxygen and therefore improve mental and physical performance.The study included 12 healthy college men and women who were randomly assigned to drink 16 ounces of tap water or super oxygenated water and then perform a multi-stage treadmill test. At each stage, heart rate, blood pressure, ratings of perceived exertion and oxygen consumption were measured. The super-oxygenated water produced no measurable effect on blood lactate values, blood pressure or heart rate. The findings were no surprise considering a commonsense understanding of physiology. Oxygenating the blood is a respiratory process, not a digestive one. One deep breath delivers more oxygen to the blood than any amount that oxygen saturated water possibly could.
Save your money, but don't discount the importance of hydration. Always drink before, during and after vigorous exercise.
