Work partitioning of transversally loaded muscle: experimentation and simulation

摘要: Skeletal muscles are surrounded by other muscles, connective tissue and bones, which may transfer transversal forces to the muscle belly. Simple Hill-type models do not consider forces. Thus, aim of this study was examine model influence loading on contraction dynamics, e.g. rate force development maximum isometric (Fim). Isometric experiments with without were conducted rat muscles. The loaded (1.3 N cm− 2) a custom-made plunger able move in direction. Then fully stimulated, measured at distal tendon movement captured high-speed camera. interaction between load modelled based energy balance (1) work done contractile component (CC) (2) lift load, stretch series elastic structu...
