Figure 2. Half‐sarcomere compliance during delayed force development.

A, force (T/T ₀) and hs length change (L) in response to 4 kHz length oscillations imposed during the isometric force development delayed by unloaded shortening starting at the end of the latent period (delay dev). Time 0 is the start of stimulation. The inset between force and hs traces shows the responses on an expanded time scale to oscillations at three different times (a–c); upper traces: force, lower traces: hs length change. B, hs compliance–force relations during dev (filled circles, same data as in Fig. 1 C) and delay dev (open circles). Continuous line: same as Fig.  1 C, dashed line: fit of delay dev data with model 2. See text for details. Parameters of the fit are reported in Table 1.
