Describe the length tension relationship

WebSep 7, 2013 · The force–length relationship seen when only sarcomere length is changed is a shallower version of that observed under simulated and experimental isovolumetric conditions. Without varying lattice spacing, the slope of the LT curve on both the ascending and descending limbs is not replicated. WebLength-tension relation measured isometrically. The main thing to note about this experiment is that the contraction of the muscle is 'isometric' which means that contraction will occur without a change in length - the muscle does not shorten! When the muscle is set at increasing lengths there will come a point where the muscle will resist ...
