We evaluated the ability of a group of male runners (n = 4) to do maximal and submaximal exercise before and after they ran a competitive marathon (42.2 km) race. VO2max was determined 3 to 6 times in each runner, on alternate days, 1-4 weeks prior…

Dynamic exercise may be used as a safe, therapeutic approach to reduce sympathetic nerve activity at rest and thus may be beneficial for individuals with hypertension. Therefore, we tested the hypothesis that a single bout of mild to moderate dynamic…

The influence of the release of endothelium-derived nitric oxide (NO) on the vasoconstrictor response to phenylephrine (PE) was evaluated before and after a single bout of dynamic exercise. Each rat ran on a motor-driven treadmill at

Naloxone eliminates postexertional hypotension (PEH) in human and animal models. The effect of naloxone on sympathetic activity during hemorrhage and generation of arterial baroreflex function curves can be stimulated by blockade of cardiac afferent…

This study was designed to test the hypothesis that the increase in sympathetic nerve activity (SNA) and mean arterial pressure (MAP) at the onset of exercise is dependent on a rapid upward shift of the operating point of the arterial baroreflex. To…
