Fig. 6. Passive forces of the unstimulated, denervated middle leg extensor tibiae. (A) Time course of passive force induced by a ramp stretch of 0.5 mm amplitude in 1 s. Note the dynamic nature of the force change and its subsequent relaxation to a nearly constant value with maintained stretch. (B) Tonic resting force versus muscle length. Data from N=10 experiments (see text for details). Please note that the number for individual means can differ (6N10).
