title: Some effects of sympathetic stimulation and isoprenaline on fatigued tetanic contractions of skeletal muscle in the cat.
abstract: In anaesthetized cats, stimulation of the lumbar sympathetic trunk inconsistently elicited small increases in the contraction of fatigued Peroneus Longus muscles (Orbeli phenomenon). Facilitation of this anti-fatigue effect was regularly observed following close intra-arterial injection of isoprenaline, a beta-adrenergic agonist. Injection of the drug by itself exerted a marked anti-fatigue effect on muscle contraction.
