... measured in isolated bundles of red fibres from 0.5 L by the work loop technique. Power was maximal at 3–4 Hz and fell to less than 50% of maximum after 6 Hz. Based on the timing of activation, muscle strain, tail beat frequencies and forces in the caudal tendon while swimming, we conclude that yellowfin...

Comparison of these data was used to examine the phase relationship between local muscle shortening and local body bending during unsteady, large amplitude maneuvers. Our analysis finds that muscle...

...Jeanine M. Donley; Robert E. Shadwick SUMMARY Patterns of red muscle strain and activation were examined at three positions along the body (0.42, 0.61 and 0.72 L , where L is total body length) and correlated with simultaneous measurements of midline kinematics during steady swimming (approx. 1.0 L...

Modelling studies related the rate of body bending to the muscle torque and hydrodynamic resistance of the fish. The muscle torque produced on the spine was greatest in the central region of the trunk...

...James M. Wakeling; Ian A. Johnston ABSTRACT White muscle strains were recorded using sonomicrometry techniques for 70 fast-starts in the common carp Cyprinus carpio L. High-speed ciné images were recorded simultaneously for 54 of these starts, and muscle strain was calculated independently from...

Rome ABSTRACT Recent attempts to determine how fish muscles are used to power swimming have employed the work loop technique (driving isolated muscles using their in vivo strain and stimulation pattern). These muscle strains have in turn been determined...
