Abstract

Intracellular potassium loss has been implicated as the basis of skeletal muscle fatigue (1). A decrease in the cell membrane K+ gradient diminishes the action potential. In turn, Ca++ release decreases and a smaller tension is developed. The largest K+ losses have been reported during high-intensity, dynamic exercise. The purpose of this study was to determine the effect of KC1 infusion on hindlimb forces in rabbits.
