TLoad is greater than TUnload in permeabilized detrusor smooth muscle (DSM). A: loading (Load) and unloading (UL) protocol used to determine the length dependencies of passive tension. B: example of a passive tension tracing of permeabilized DSM subjected to the protocol shown in A. C: summary data showing that for each length step, the tension values produced on muscle loading were greater than those produced on unloading. TL4, pseudo steady-state tension value at the 4th loading length. Data in C are means ± SE, n = 3. *P < 0.05 compared with TLoad, Student's t-test.
