title: Quick release by shortening both ends of the muscle fibre.
abstract: A method is described allowing in quick release experiments the sensing of tension transients as well as the release on each of both ends of the muscle simultaneously. Preliminary results indicate a delay and differences in the time course of the tension transients between the released end and the fixed end. The delay corresponds to the propagation velocity of the mechanical wave. The elasticity of the muscle computed from the propagation velocity is compared with the elasticity determined by Young's modules.
