Acute Normobaric Hypoxia Lowers Executive Functions among Young Men despite Increase of BDNF Concentration.

ABSTRACT:

Background

Decreased SpO₂ during hypoxia can cause cognitive function impairment, and the effects of acute hypoxia on high-order brain functions such as executive processing remain unclear. This study's goal was to examine the impact of an acute normobaric hypoxia breathing session on executive function and biological markers.

Methods

Thirty-two healthy subjects participated in a blind study performing two sessions of single 30 min breathing bouts under two conditions (normoxia (NOR) and normobaric hypoxia (NH), FIO₂ = 0.135). The Stroop test was applied to assess cognitive function.

Results

No significant difference was observed in the Stroop interference in the "reading" part of the test in either condition; however, there was a significant inc
