Ascorbic acid increases cardiovagal baroreflex sensitivity in healthy older men.
Cardiovagal baroreflex sensitivity (BRS) declines with advancing age in healthy men. We tested the hypothesis that oxidative stress contributes mechanistically to this age-associated reduction. Eight young (23 +/- 1 yrs, means +/- SE) and seven older (63 +/- 3) healthy men were studied. Cardiovagal BRS was assessed using the modified Oxford technique (bolus infusion of 50-100 microg sodium nitr...
متن کاملRegular aerobic exercise prevents and restores age-related declines in endothelium-dependent vasodilation in healthy men.
BACKGROUND In sedentary humans endothelium-dependent vasodilation is impaired with advancing age contributing to their increased cardiovascular risk, whereas endurance-trained adults demonstrate lower age-related risk. We determined the influence of regular aerobic exercise on the age-related decline in endothelium-dependent vasodilation. METHODS AND RESULTS In a cross-sectional study, 68 hea...
متن کاملRegular endurance exercise in young men increases arterial baroreflex sensitivity through neural alteration of baroreflex arc.
Endurance exercise training increases arterial baroreflex sensitivity that corresponds to alteration in vessel wall compliance of the carotid artery in elderly men. Here, we examined whether regular endurance exercise increases arterial baroreflex sensitivity through neural alteration of the baroreflex arc in young men. We assessed arterial baroreflex sensitivity in eight sedentary men (age 24 ...
متن کاملRespiratory modulation of cardiovagal baroreflex sensitivity.
Emerging evidence has suggested that with minimal prerequisite training, slow deep breathing around 0.10 Hz can acutely enhance cardiovagal baroreflex sensitivity (BRS) in humans. Such reports have led to the speculation that behavioral interventions designed to reduce breathing frequency may serve a therapeutic role in ameliorating depressed baroreflex function in conditions such as chronic he...
متن کاملCentral arterial compliance is associated with age- and habitual exercise-related differences in cardiovagal baroreflex sensitivity.
Background- Cardiovagal baroreflex sensitivity (BRS) declines with age but is favorably modulated by habitual aerobic exercise. We tested the hypothesis that compliance (transducing capacity) of an elastic artery in which baroreceptors are located is associated with these age-exercise interactions. Methods and Results- Nine young (28+/-1 years old) and 9 older (65+/-1) sedentary and 10 young (2...
