Key result
High cardiorespiratory fitness in older men was associated with significantly higher baroreflex sensitivity during head-up-tilting compared to being physically unfit (7.5 vs 3.0 ms/mmHg, p=0.001).
Why the study?
Does high cardiorespiratory fitness improve cardiac autonomic nervous activities and baroreflex sensitivity in healthy older men?
Cross-Sectional (n=24)
Does high cardiorespiratory fitness improve cardiac autonomic nervous activities and baroreflex sensitivity in healthy older men?
Absolute Event Rate: 7.5% vs 3%
p-value: p=0.001
High cardiorespiratory fitness is associated with preserved cardiac autonomic nervous system activity and baroreflex sensitivity in healthy older men.

Hypothesis-generating for fitness effects on autonomic function; prospective trials needed before clinical adoption in older men.
Ueno et al. (2002) conducted a cross-sectional in Healthy (n=24). High cardiorespiratory fitness (physically fit) vs. Low cardiorespiratory fitness (physically unfit) was evaluated on Baroreflex sensitivity (BRS) during passive head-up-tilting (p=0.001). High cardiorespiratory fitness in older men was associated with significantly higher baroreflex sensitivity during head-up-tilting compared to being physically unfit (7.5 vs 3.0 ms/mmHg, p=0.001).
