Baudry S, et al. - The impacts of short-term glucocorticoid administration on voluntary activation and intracortical inhibitory and facilitatory circuits are examined in this study. The outcome of the current study shows that the short-term dexamethasone treatment induced a specific decrease in the excitability of intracortical inhibitory circuits that likely contributed to the increase in the voluntary activation and related maximal voluntary contraction (MVC) torque.
