[Effect of cold adaptation on energy-dependent ionic transport in fibers of rat skeletal muscles].
The resting MP of the m. gastrocnemius medialis fast fibers and the m. soleus slow ones was measured prior to and after 15 and 30 min of the strophanthin local effect in control and cold-adapted rats. A greater effect was observed in the m. gastrocnemius medialis fibers in control rats, whereas a more obvious depolarization effect occurred in the m. soleus fibers in cold-adapted rats. Cold adaptation seems to induce changes of metabolic contribution in the rate of resting MPs in different types of muscular fibers.
