Parameter identification for a distribution-moment model describing the active beha vior of the tibialis anterior muscle of the rat

摘要

In muscle adaptation mechanical loads play an important role. External loads (e.g. total force) of the muscle results in regional loads (stresses and strains) within the tissue, which are supposed to be responsible for muscle adaptation. To study the influence of mechanical load on muscle tissue a continuum model of the tibialis anterior (TA) of the rat is developed by Gielen (1998). In this continuum model the contractile properties of the rats TA are described by a distribution-moment (DM) model (Ma, 1988, Ma and Zahalak, 1991). The objective of the present research is to identify the unknown DM parameter values for the rats TA.
