Summary The effect of intra‐arterial infusion of the β ‐adrenoreceptor blocking agent propranolol and the α ‐adrenoreceptor blocking agent phenoxybenzamine on post‐exercise hyperaemia has been examined in the human forearm. The post‐exercise hyperaemia was significantly reduced by propranolol. but not affected by phenoxybenzamine. The reduction of the post‐exercise hyperaemia by propranolol appears to be due to its β ‐adrenoreceptor blocking action on adrenaline, released as a result of the emotional stress involved in performing the exercise.
