Normobaric Hypoxia and Submaximal Exercise Effects on Running Memory and Mood State in Women

Abstract

Hypoxia and an acute bout of exercise partially influence RMCPT and TMD. Furthermore, a moderate-intensity bout of exercise (60%) may be a more potent stimulant for improving cognitive function than low-intensity (40%) exercise. The present data should be considered by aeromedical personnel performing cognitive tasks in hypoxia.Seo Y, Gerhart HD, Stavres J, Fennell C, Draper S, Glickman EL.

The interactive effects of acute exercise and hypoxia on cognitive performance: A narrative review

“…Therefore, the impact of age and sex on cognitive performance when acute exercise is combined with hypoxia is unclear. Nevertheless, the role of sex differences may not be important as Seo and colleagues 24,25 have previously reported similar results in both male and female participants. Collectively, the present findings regarding the effects of exercise under hypoxia on cognitive performance are inconsistent.…”

“…For example, in the case of moderate exercise and/or brief exposure to hypoxia, the beneficial effects of acute exercise outweigh the detrimental effects of hypoxia. Indeed, when duration of exposure to hypoxia is relatively short (~105 minutes), cognitive improvements are frequently observed during exercise . In contrast, in the case of severe and/or prolonged exposure to hypoxia, the beneficial effects of acute exercise appear to be negated by the detrimental effects of hypoxia or are unable to override the detrimental effects.…”

“…Indeed, when duration of exposure to hypoxia is relatively short (~105 minutes), cognitive improvements are frequently observed during exercise. [20][21][22][24][25][26] In contrast, in the case of severe and/or prolonged exposure to hypoxia, the beneficial effects of acute exercise appear to be negated by the detrimental effects of hypoxia or are unable to override the detrimental effects. The effects of acute exercise on cognitive performance depend on exercise intensity and duration, while the severity and duration of exposure to hypoxia are crucial for the detrimental effects on cognitive performance.…”

“…In follow-up studies, Komiyama et al 21 reported cognitive improvement in the GNG and spatial delayed response tasks during moderate exercise in moderate hypoxia and severe hypoxia. 22 Seo and colleagues [23][24][25] examined the combined effects of moderate exercise and in severe hypoxia in both male 23,24 and female 23,25 participants. The same group reported cognitive improvement in memory [23][24][25] and mathematical performance, 23 but not in the GNG task.…”
