Abstract
A technique of obtaining muscle biopsies with a liquid nitrogen cryoprobe was used to study intramuscular metabolites in MH-susceptible and unsusceptible pigs. There was no significant difference in muscle metabolite values obtained from susceptible and unsusceptible pigs in the resting state. During MH the changes in metabolites were a result of rapid glycogenolysis and no abnormality of glycolytic control was observed.
