Small (1%) length decreases in single muscle fibers reduce tension almost entirely through a decrease in calcium release rather than changes in mechanical factors.
Absolute Event Rate: 0% vs 0%
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.
Ridgeway et al. (Fri,) reported a other. Small (1%) length decreases in single muscle fibers reduce tension almost entirely through a decrease in calcium release rather than changes in mechanical factors.
