The effects of superoxygenated water compared with regular bottled water on heart rate and arterial oxygen saturation

[摘要] This study measured and compared the effects of superoxygenatedwater (SW) to regular bottled water (RW) on heart rate (HR), arterialoxygen saturation (% saturation), and rates ofdesaturation/resaturation (112 times) in response to artificially inducedRypoxia. Methods: 20 subjects were randomly assigned to drinkeither 20 oz or 40 oz of SW for one trial and RW for the other trial.After a 30-minute rest period following ingestion of the assignedwater, subjects inhaled a 40% oxygen mixture for 3 minutes followedby 5 minutes of breathing room air. This breathing cycle was repeated2 more times consecutively. Results: No significant differences werefound in HR, % saturation, or 1/2 times between SW and RW trials.Conclusion: In artificially induced hypoxia, SW results in nosignificant changes in HR, % saturation, or rates of saturation changecompared 80 RW, suggesting benefits to exercise performance wouldbe unlikely to result from ingestion of SW.
