Inhibition by a capsaicin antagonist (capsazepine) of capsaicin-induced swimming capacity increase in mice

Abstract

We investigated the endurance swimming capacity of mice injected with CAP antagonist (capsazepine). The increase of endurance swimming capacity by the administration of CAP was significantly suppressed by the injection of capsazepine. At the same time, serum adrenaline secretion, which was induced by CAP, was depressed by capsazepine. These findings suggested that the increase in endurance swimming capacity by CAP was mediated by the CAP receptor. © 1998, Taylor & Francis Group, LLC. All rights reserved.
