Fitness-linked baroreflex attenuation should not change exercise guidance; leaves open its role in blood-volume adaptations and clinical outcomes.
Does physical fitness alter the cardiopulmonary baroreflex control of forearm vascular resistance in humans?
Physical fitness attenuates the gain of cardiopulmonary baroreflex control of forearm vascular resistance, an adaptation related to increased total blood volume.
Mack et al. (1987) studied this question.
