Figure 8
Comparison of X-ray diffraction patterns taken between an isometric contraction before shortening (a) and during shortening near the maximum velocity (b). The patterns were recorded by using the rapid image-plate exchanger. The fibre axis is vertical. Note the intensity decreases in the meridional reflections with a 14.5 nm repeat and the 5.1 and 5.9 nm actin layer lines during shortening. |
