Population
14 individuals, comprising 7 average fit (AF) and 7 high fit (HF) subjects
Comparison

High aerobic fitness was associated with blunted baroreflex gain during hypovolaemia; hypothesis-generating for orthostatic intolerance mechanisms in athletes.
Does aerobic fitness affect carotid baroreflex responsiveness during head-up tilt-induced central hypovolaemia?
Endurance-trained individuals exhibit attenuated increases in carotid baroreflex responsiveness during central hypovolaemia, which may explain their predisposition to orthostatic intolerance.
Ogoh et al. (2003) studied this question.
