Contracture

08/01/1993 - "After Ca2+ loading (120 s), the minimal caffeine concentration required to evoke a contracture in fatigued fibers (5.7 +/- 0.3 mM) was significantly greater than that of control fibers (3.1 +/- 0.4 mM), an effect that persisted with prolonged incubation of the skinned fibers. "
