This preclinical study demonstrates distinct electrophysiological properties in rat skeletal muscles, showing that slow-twitch soleus muscle has both fast and slow components of potassium outward current, whereas fast-twitch iliacus muscle has only a fast component.

Distinguishes K+ current kinetics by fiber type in rat muscle; leaves open translation to human physiology or disease models.
Duval et al. (1980) studied this question.
