The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. According to the sliding filament theory, the myosin (thick filaments) of muscle fibers slide past the actin (thin filaments) during muscle contraction, while the two groups of filaments remain at relatively constant length. The theory was independently introduced in 1954 by two research teams, one consisting of Andr… WebbRegulatory Proteins Tropomyosin and troponin are two main proteins that regulate muscle contraction and relaxation (Choi and Kim, 2009; Zot and Potter, 1987).
