Fig. 6. White muscle strains measured by sonomicrometry at both axial locations (0.4L and 0.7L) closely match strains estimated from body curvature, but this trend deviates at higher strains. Peak (black circles), initial and final (gray circles) strains were measured during induced fast-starts. The solid line represents the linear regression through initial, peak and final strains (r²=0.82, P<0.05). The strain relationship of a homogeneous bending beam is expressed by the dashed line.
