摘要

This paper evaluates the role of active and passive muscle forces in the failure mechanism of stimulated muscle. An in vivo rabbit is used as a model. The triceps surae muscle-tendon units of the model are passively stretched to rupture with or without continuous nerve stimulation. Active muscle force, passive muscle force, and ratio of the active to passive muscle are calculated and depicted against strain. Results show that the mean maximal passive force of triceps surae muscle is 293.1 n at a strain of 38%. The mean peak active muscle force is 21.5 N at a strain of 21%. The ratio of active to passive muscle force reached its peak first followed by the active muscle force, and then the passive muscle force. The ratio of active to passive muscle force at the peak total force is only 3.3%.
