Outline of Final Research Achievements

The purpose of this study was to examine the combined effects of acute exercise and severe hypoxia on cognitive function. The participants completed cognitive tasks at rest and during moderate exercise under either normoxic or severe hypoxic conditions. Cognitive performance improved during exercise under both normoxia and hypoxia, without sacrificing accuracy. However, under hypoxia, cognitive improvements were attenuated for individuals exhibiting a greater decrease in arterial oxygen saturation. The present results suggest that arterial desaturation and resultant biological processes attenuate cognitive improvements during exercise under hypoxia.
