Abstract
AbstractThe time lag between the activation of a muscle and the development of force is commonly denoted as electromechanical delay (EMD). Within this work, a multi‐scale model of an idealized muscle‐tendon system is used to analyze EMD on different characteristic anatomical length scales. Thereby, the simluated EMD‐stretch curves for a complete muscle‐tendon system and a single sarcomere are significantly different. While for an isolated muscle EMD is shown to be strongly determined by excitation‐contraction coupling (ECC), the EMD‐stretch curve for a complete muscle‐tendon system is influenced by additional factors, such as, e.g., the tendon. Further, it is shown that the action potential conduction velocity (APCV) has minor influence on EMD.
