.... However, the cost magnitude relative to the cost of mechanical work, which features in many movements, is unknown. We therefore tested whether fast activation is costly compared with performing work or producing isometric force. We hypothesized that metabolic cost would increase with a proposed measure...

...Uzma Tahir; Jenna A. Monroy; Nicole A. Rice; Kiisa C. Nishikawa ABSTRACT The active isometric force produced by muscles varies with muscle length in accordance with the force–length relationship. Compared with isometric contractions at the same final length, force increases after active lengthening...

...Bethany A. Paterson; Ilya Marko Anikin; Jacob L. Krans SUMMARY We describe neuromuscular hysteresis – the dependence of muscle force on recent motoneuron activity – in the body wall muscles of larval Sarcophaga bullata and Drosophila melanogaster . In semi-intact preparations, isometric force...

... isometric force calcium transport Muscles consume metabolic energy both when performing mechanical work and when simply producing force without work. Most straightforward is the energetic cost of performing work, which occurs at an efficiency of up to 25%( Woledge et al., 1985 ). Less...

... fibre bundles) (means ± S.E.M.). Part, but not all, of the difference is due to mitochondrial content. The maximum unloaded shortening velocity, 1.693±0.108 L 0 s -1 ( N =6 fibre bundles), was measured by the slack-test method. L 0 is the length giving maximum isometric force. The force/velocity...
