Why the study?
Cerebrovascular and ventilatory responses to exercise pressor activation had not been measured in women, and the effect of posture change on metaboreflex response had only been tested in men.
Does sex and posture affect the ventilatory and cardiovascular response to metaboreflex activation in young healthy adults?
Population
14 young healthy men and 11 young healthy women
Comparison
Men vs women during static handgrip and post-exercise circulatory occlusion in supine vs 70 degree tilted postures
Design
Physiological comparison study

Supports sex-specific ventilatory responses to metaboreflex activation; leaves open clinical relevance of posture effects in disease.
Does sex and posture affect the ventilatory and cardiovascular response to metaboreflex activation in young healthy adults?
Men and women exhibit sexually dimorphic ventilatory responses to metaboreflex activation, and both sexes show attenuated metaboreflex function in the upright posture.
