New insights into arterial baroreflex function during acute exercise: role of central angiotensin II

Cardiovascular response to postural perturbations of different intensities in healthy young adults

“…Second, the relatively concurrent reduction in R-R interval and rise in SBP suggest baroreflex resetting is occurring (Raven et al, 2019). While the exact cause of baroreflex is not fully understood, the invocation of a baroreflex resetting outcome immediately following the perturbation is consistent with the concept of a feed-forward mechanism emanating from central neural sites (Krogh & Lindhard, 1913;Matsukawa, 2012;Migdal & Robinson, 2018). Whereas the muscle metaboreflex associated with fatiguing muscle contractions are also suspected in the baroreflex resetting process (Raven et al, 2019) it is unlikely that this mechanism participated in the current study because of the very brief and submaximal levels of the leg muscles during the approximately 8 s period of work.…”
