The relation between external potassium concentration and the relaxation rate of potassium-induced contractures in frog skeletal muscle

1. Frog toe muscles and isolated fibres from frog semitendinosus muscles were allowed to develop maximum K-contractures, and after reaching peak tension were transferred to media containing intermediate [K] 0 (20-40 m M -K). Under these circumstances, relaxation displayed an early rapid phase, and a...
