The purpose of this investigation was to determine the relationship between calcium and glucose uptake following muscle contraction with the use of the calcium channel blocker dantrolene. In previous studies an exercise model has been used to investigate the role of calcium during post-exercise glucose uptake. This study utilized electrical stimulation. It has been shown that exercise-induced glucose uptake is calciummediated, but to date no one has shown that glucose transport induced by electrical stimulation is calcium-mediated. Twenty four male Sprague Dawley rats weighing 140 g were sacrificed and their epitrochlearis muscles were removed. Four treatment groups were established: control, muscle incubated in glucose (4mM); insulin, muscles incubated in glucose (4mM) and insulin (1000uU/ml); electrical stimulation, at 50 Hz for two five minute intervals separated by one minute rest periods; insulin (1000uU/ml) and electrical stimulation at 50 Hz for two five minute intervals separated by one minute intervals. Each group consisted of contain 8-10 muscle preparations. Glucose uptake was measured through the use of a double label of radioactive mannitol and 3-O-methylglucose and analyzed using liquid scintillation. This project followed a randomized group design. Treatments were measured with a one way ANOVA. / School of Physical Education
