Key result
Inspiratory resistance up to 7.5 cm H2O·L−1·s−1 during maximal cycling exercise in hypoxia did not significantly impair cognitive function or mood state in 9 healthy men.
Why the study?
Does added inspiratory resistance impair cognitive function and mood state during maximal exercise in hypoxia in healthy men?
Does added inspiratory resistance impair cognitive function and mood state during maximal exercise in hypoxia in healthy men?
Added inspiratory resistance during maximal exercise in hypoxia does not impair cognitive function or mood state in healthy men.
Answers are grounded in this paper and cite their sources.
Added resistance appears tolerable for cognition and mood in hypoxia; leaves open effects in patients or at higher loads.
This study evaluated cognitive function and mood state with inspiratory resistance before and after maximal exercise in hypoxia. Nine healthy men (age = 25 ± 2 years) performed the Automated Neuropsychological Assessment Metrics—4th Edition (ANAM4) of the Stroop color–word test (SCWT) and total mood disturbance (TMD) before and after an incremental cycling exercise until volitional fatigue with four different inspiratory resistances (0, 1.5, 4.5, 7.5 cm H2O·L−1·s−1). There was no significant difference in the interference score of SCWT and TMD at normobaric, hypoxic conditions at four different inspiratory resistances. However, the interference score of SCWT was improved following maximal cycling exercise, whereas TMD was not improved. Inspiratory resistance did not have a deleterious effect on cognitive function and mood state in normobaric hypoxia after maximal cycling exercise. However, following maximal cycling exercise, cognitive function was improved.

Yongsuk Seo (2023) studied Healthy (n=9). Inspiratory resistance vs. 0 cm H2O·L−1·s−1 was evaluated on Cognitive function (interference score of SCWT) and mood state (TMD). Inspiratory resistance up to 7.5 cm H2O·L−1·s−1 during maximal cycling exercise in hypoxia did not significantly impair cognitive function or mood state in 9 healthy men.
