Abstract

In this paper, the problems existing in the mechanism of eccentric contraction are explained by analyzing the theory of sliding filament models. The two-filament sarcomere model (thick and thin filament) modified or updated with the three-filament sarcomere model (the thin, the thick and the third filament, titin) in  sliding filament theory is introduced and discussed.
