Key result
Female sex was associated with an attenuated rapid-onset vasodilation response to single forearm contractions in older but not young adults.
Why the study?
Rapid-onset vasodilation decreases in older individuals, but whether sex contributes to this decline with aging is unclear.
Do sex-related differences exist in the rapid-onset vasodilation response to single forearm contractions in young and older adults?
Observational
Do sex-related differences exist in the rapid-onset vasodilation response to single forearm contractions in young and older adults?
The study demonstrates that the age-related decline in rapid-onset vasodilation is more pronounced in women, highlighting sex-specific vascular aging.
While rapid-onset vasodilation (ROV) has been shown to decrease in older individuals, it is unclear if sex contributes to the decline with aging. We sought to identify if sex-related differences exist in the ROV response to single forearm contractions in young and older adults. Our data suggest sex-related differences are present among older but not young individuals, with women having an attenuated response. These data indicate sex plays a role in decreased vasodilation with aging.
