Two experiments were conducted to investigate the extent to which subjects can compensate for the effects of elbow angle on the mechanical efficiency of the elbow muscle‐joint system. Subjects were found to be able to match movements made in different directions and made from different starting‐points but unable to match isometrically produced torques made under comparable conditions. The results are compatible with the hypothesis that subjects possess a limited motor‐constancy mechanism operating on the basis of temporal modulation of muscle activity.
