The passive tension is also related to what is referred to as passive myocardial stiffness.
Granzier, H. L. & Irving, T. C. Passive tension in cardiac muscle: contribution of collagen, titin, microtubules, and intermediate filaments.
In contrast to active tension, the passive tension model deviated from experimentally-measured values and thus, was not an accurate predictor of passive tension (ICC=0.70±0.07).
Passive tension was modeled with a two-element Hill-type model.
It is known that titin passive tension is directly linked to isoform size, so changes in isoform allow fine-tuning of titin's function to the wide types of muscles in vertebrates.
Greaser, M. L., Berri, M., Warren, C. M. & Mozdziak, P. E. Species variations in cDNA sequence and exon splicing patterns in the extensible I-band region of cardiac titin: relation to passive tension.
This requires that in order to achieve a momentarily static equilibrium position of the AV plane during diastasis8,26, other forces, such as passive tension, must oppose the hydraulic forces.
Experimental results during 30° dorsiflexion showed that muscle stretching induced an exponential increase in passive tension developed by the musculo-tendinous entity.
hESC-CMs within the patch were aligned uniformly by locally controlling the direction of passive tension.
We have also developed a method to calculate the passive tension generated by the engineered muscle tissue bundles suspended between two pillars.
We studied the dose-dependent effect of cardiotoxin on the engineered muscle tissue architecture and its subsequent effect on the passive tension.
