Should not change practice; hypothesis-generating for exercise effects on sympathetic baroreflex control.
p-value: p=<0.05
Treadmill exercise in rats induces an acute right-upward shift in baroreflex control of sympathetic nerve activity, which may stabilize arterial pressure during exercise and contribute to post-exercise hypotension upon cessation.
Miki et al. (2003) studied this question. Treadmill exercise vs. Pre-exercise level was evaluated on Pa-RSNA baroreflex curve parameters (response range, maximum response, maximum gain, midpoint pressure) (p=<0.05). Treadmill exercise shifted the Pa-RSNA baroreflex curve upward and to the right, significantly increasing response range, maximum response, maximum gain, and midpoint pressure (P<0.05).
