It is usually accepted that the phenomenon of thick filament shortening contradicts the sliding filament theory and cross-bridge mechanism of force generation. However, some peculiarity of experimental data indicate the thick filament shortening can be a corollary of the interaction of myosin cross-bridges with the actin filaments "wrong" polarities in sarcomeres with the actin filaments double overlap formed in the results of the filament sliding.
通常认为,粗肌丝缩短现象与肌丝滑行理论及力产生的横桥机制相矛盾。然而,实验数据的一些特性表明,粗肌丝缩短可能是肌球蛋白横桥与肌动蛋白丝相互作用的必然结果,这种相互作用发生在肌节中肌动蛋白丝具有“错误”极性且因肌丝滑行而形成肌动蛋白丝双重重叠的情况下。
