Muscle activation: effects of small length changes on calcium release in single fibers.

E B Ridgeway, A M Gordon.   

Abstract

In single muscle fibers, small (1 percent) changes of length have a marked effect of both the calcium activation and the tension elicited by a constant current stimulus. The decrease in tension with shortening is accounted for almost entirely by a decrease in calcium release, rather than by changes in mechanical factors, such as filament geometry.
