The purpose of this study was to examine the effects of the adrenergic receptors on the distribution of blood flow within and among skeletal muscles in rats. Blood flow was measured with the radiolabeled microsphere technique before exercise and during treadmill exercise at 15 or 60 m/min. Alpha- (phentolamine) or beta- (propranolol) adrenergic blocking drugs were administered, and then blood flow was measured and results compared with those from saline-treated rats. Before exercise, alpha… CONTINUE READING
