Cognitive Performance, Hyperoxia, and Heart Rate Following Oxygen Administration in Healthy Young Adults

Research image

It was recently established that supplemental oxygen administration significantly enhances memory formation in healthy young adults. In the present study, a double-blind, placebo-controlled design was employed to assess the cognitive and physiological effects of subjects’ in-spiration of oxygen or air (control) prior to undergoing simple memory and reaction-time tasks. Arterial blood oxygen saturation and heart rate were monitored during each of six phases of the experiment, corresponding to baseline, gas inhalation, word presentation, reaction time, distractor and word recall, respectively. The results confirm that oxygen administration significantly enhances cognitive performance above that seen in the air inhalation condition. Subjects who received oxygen recalled more words and had faster reaction times.

"...Insufficient oxygen means insufficient biological energy that can result in anything from mild fatigue to life threatening disease.The link between insufficient oxygen and disease has now been firmly established. The more oxygen we have in our system, the more energy we produce."

"I tried Boost Oxygen for the first time at the opening round at Brands Hatch while competing in the Porsche Club Championship. What a difference it made! I had my best ever qualifying and race result as well as my fastest lap time. I will certainly be using Boost Oxygen in the future."
