Figure 4.
Comparison of theoretical and experimental non-cross-bridge force traces during eccentric contractions. Blue solid lines indicate depressed force responses (around 94% cross-bridges abolished) due to 10 mM BDM application (mean (solid lines) ± s.d. (shaded regions around solid lines) of 14 valid experiments) for eccentric ramps with stretch velocity of 11% vmax and initial fibre lengths of 0.85 L0 (a) and 1.0 L0 (b), respectively. The blue dashed lines are expected to have non-cross-bridge forces (method B, see §2f) assuming a valid isometric FLR (black dashed lines) during eccentric contraction.
