Effects of Dynamic and Static Loads on the Concentration of Sodium and Potassium in Murine Skeletal Muscles

The effects of dynamic and static load on the intracellular concentrations of sodium (Na_i^+) and potassium (K + i ) in m. soleus and m. biceps , respectively, were studied in mice. Both dynamic (swimming for 60 min) and static (hanging on the grid for 40 min) load led to a 2-fold increase in Na_i^+ level, a decrease in K + i concentration by 25-35
