Abstract :
The purpose of this study was to explore theoretically and experimentally the effects of antagonistic muscle activity on the forces of synergistic muscles. Forces in the soleus (S), lateral gastrocnemius (LG), and anterior tibialis (AT) muscles of the left cat hindlimb were measured for level walking at 0.65 m/s using buckle tendon transducers. Force produced by the S and LG were calculated first incorporating AT forces and then assuming AT forces to be zero. Antagonistic forces were found to be the highest at the end of the stance phase. However, the absolute change in joint moment due to antagonistic forces did not appear to be of practical significance.<>
