Abstract:In this review, we discuss the morphologic influence of clenbuterol on muscle atrophy with particular focus on cast-immobilization used in surgical care. β 2 -agonists induce muscle hypertrophy, particularly in fast muscles. Similar to these anabolic actions, the β 2 -agonist clenbuterol attenuates immobilization-induced atrophy in fast muscles. Furthermore, the attenuating effects of this agonist on muscle atrophy may be related to its preventative effect in fast muscle fibers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
