Figure 2


Fig. 2. Time course of force development by the ventral interior lateral muscle (VIL) under tetanic stimulus at resting length. An example is shown of a typical force response to a 30 V, 20 Hz stimulus train for 2 s, beginning at 1 s in the figure. Peak stress of 138.6±74.2 kPa (mean ± s.d.) was reached in 2.22±1.33 s (N=19); individual muscle preparations reached 80% of their peak force in 0.56±0.24 s.
