Differences in cardiovascular responses to isoproterenol in relation to age and exercise training in healthy men.
BACKGROUND Cardiac aging is characterized by a reduced heart rate response to beta-agonist stimulation with isoproterenol, but whether the ejection fraction and other cardiovascular responses are reduced in humans is largely unknown. In addition, whether reduced beta-agonist responses can be improved with exercise training has not been determined in humans. METHODS AND RESULTS Cardiovascular ...

15 صفحه اول1648 Cardiovascular Responses to Exercise Effects of Aging and Exercise Training in Healthy Men
Background Cardiac aging alters many of the acute responses to exercise stress, but the extent to which chronic exercise (ie, training) can alter or improve the effects of aging in humans is largely unknown. Methods and Results Cardiovascular responses to graded supine exercise stress (beginning at 200 kpm and increasing by 200 kpm every 3 minutes till exhaustion) were assessed using radionucli...
