WebSep 12, 2024 · What is the sliding filament theory for dummies? The theory of contraction called the Interdigitating Filament Model of Muscle Contraction, or the Sliding Filament Theory of Muscle Contraction, says that the myosin of the thick filaments combines with the actin of the thin filaments, forming actomyosin and prompting the filaments to slide past … The first muscle protein discovered was myosin by a German scientist Willy Kühne, who extracted and named it in 1864. In 1939 a Russian husband and wife team Vladimir Alexandrovich Engelhardt and Militsa Nikolaevna Lyubimova discovered that myosin had an enzymatic (called ATPase) property that can breakdown ATP to release energy. Albert Szent-Györgyi, a Hungarian physiologist, turned his focus on muscle physiology after winning the Nobel Prize in Physiology o…
