Figure 3.
(A) Submaximal force at steady-state SL = 2.3 μm (blue trace) or after a quick stretch from steady-state SL = 2.0 μm (red trace). (B) Submaximal activation at steady SL = 2.3 μm (blue trace) or after a quick release from steady-state SL = 2.5 μm (green trace). Inorganic phosphate was removed by an enzymatic phosphate mop. Calibration bars: 40 nN for force, 0.15 Lo for muscle length, and 2 s for time.
