From: Force produced after stretch in sarcomeres and half-sarcomeres isolated from skeletal muscles
Typical experiment overview.
A - Superimposed force traces (upper panel) and length traces (lower panel), from a single sarcomere activated in pCa2+ 4.5 and kept isometric (in black) or stretched during activation (in red). B - Superimposed force traces (upper panel) and length traces (lower panel), from a half-sarcomere activated in pCa2+ 4.5 and kept isometric (in black) or stretched (in red). In both cases, force enhancement (FE) was calculated as the difference between the isometric (in black) and steady state force (in red) achieved after stretch. Note that for the actual FE calculation, the passive component was also taken into account.
