Attenuated arterial baroreflex in high-fit adults suggests fitness-related autonomic adaptation; leaves open prospective cardiovascular implications.
Does high aerobic fitness alter arterial, aortic, and carotid-cardiac baroreflex sensitivity compared to average fitness in healthy young adults?
High aerobic fitness is associated with attenuated arterial-cardiac reflex sensitivity, mediated by diminished aortic baroreflex function, while the integrative relationship between aortic and carotid baroreflexes remains inhibitory.
