Abstract

Background Previous study shows a respiratory effector of carotid baroreceptor activation: the respiratory resistance. In the present study the age-related changes of respiratory response to carotid baroreceptor activation were studied.
Material and methods 125 healthy men 21-70 years old were involved in the study. The heart responses (the increase in R-R interval) and reflex changes of respiratory resistance were analysed during activation of carotid baroreceptors.
Results In the younger groups of subjects (21-40) a brief decrease of respiratory resistance was observed in response to carotid baroreceptors activation. In the course of aging we found a decrease of heart response and a disappearance of respiratory response.
Conclusions We suggest that both components of carotid baroreceptors reflex: cardiac and respiratory, are impaired during biological aging.
