Key result
Combined mechanoreflex and metaboreflex activation produces additive cardiovascular responses regardless of sex or hormone phase.
Why the study?
The muscle mechanoreflex may be sensitized by metabolites during exercise, but the cardiovascular effects of combined mechanoreflex and metaboreflex activation across sex and female hormone phases remained to be evaluated.
Do cardiovascular responses to combined mechanoreflex and metaboreflex activation differ between males and females or across hormone phases in females?
Do cardiovascular responses to combined mechanoreflex and metaboreflex activation differ between males and females or across hormone phases in females?
Cardiovascular responses to combined mechanoreflex and metaboreflex activation are additive and do not differ by sex or female hormone phase, providing insight into blood pressure responses during exercise.
Answers are grounded in this paper and cite their sources.
Cardiovascular responses to exercise appear consistent across sexes; leaves open translation to clinical populations with altered reflexes.
The muscle mechanoreflex may be sensitized by metabolites during exercise. We show that cardiovascular responses to combined mechanoreflex (passive cycling) and metaboreflex (postexercise circulatory occlusion) activation are primarily additive and do not differ between males and females, or across variations in sex hormones in females. Our findings provide new insight into the contributions of muscle mechanoreflex-metaboreflex interactions as a cause for prior reports that females have smaller blood pressure responses to voluntary exercise.

Lee et al. (2023) studied Healthy adults. Combined mechanoreflex (passive cycling) and metaboreflex (postexercise circulatory occlusion) activation vs. Males and different hormone phases in females was evaluated on Cardiovascular responses. Combined mechanoreflex and metaboreflex activation produced primarily additive cardiovascular responses that did not differ between males and females or across sex hormone phases in females.
