The history-dependent features of muscle force production: A challenge to the cross-bridge theory and their functional implications

D Hahn, S Han, V Joumaa - Journal of Biomechanics, 2023 - Elsevier
The cross-bridge theory predicts that muscle force is determined by muscle length and the
velocity of active muscle length changes. However, before the formulation of the cross …
