Thin filament activation and unloaded shortening velocity of rabbit skinned muscle fibres.

The Journal of physiology - 1 Jul 2003

Morris Carl A, Tobacman Larry S, Homsher Earl

Abstract excerpt

The unloaded shortening velocity of skinned rabbit psoas muscle fibres is sensitive to [Ca2+]. To determine whether Ca2+ affects the unloaded shortening velocity via regulation of crossbridge kinetics or crossbridge number, the shortening velocity was measured following changes in either [Ca2+] o...
