Why the study?
To evaluate sex differences in the reliability of absolute and relative cerebral blood velocity during concurrent supine cycling with lower body negative pressure.
Does sex influence the reliability of cerebral blood velocity regulation during lower body negative pressure and supine cycling?
Does sex influence the reliability of cerebral blood velocity regulation during lower body negative pressure and supine cycling?
Both relative and absolute cerebral blood velocity demonstrated high reliability in male and female participants during a supine LBNP cycling protocol, suggesting females can be included in future LBNP studies at any menstrual cycle stage.
No takes yet. Share an insight, caveat, or question.
CBv reliability during LBNP-augmented cycling appears comparable between sexes; leaves open menstrual cycle effects for larger prospective studies.
Johnson et al. (2023) studied this question.
