Abstract

This study measured and compared the effects of superoxygenated water (SW) to regular bottled water (RW) on heart rate (HR), arterial oxygen saturation (% saturation), and rates of desaturation/resaturation (112 times) in response to artificially induced Rypoxia. Methods: 20 subjects were randomly assigned to drink either 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 assigned water, subjects inhaled a 40% oxygen mixture for 3 minutes followed by 5 minutes of breathing room air. This breathing cycle was repeated 2 more times consecutively. Results: No significant differences were found in HR, % saturation, or 1/2 times between SW and RW trials. Conclusion: In artificially induced hypoxia, SW results in no significant changes in HR, % saturation, or rates of saturation change compared 80 RW, suggesting benefits to exercise performance would be unlikely to result from ingestion of SW.
