'Dynamic' transverse mechanical properties of rat skeletal muscle under in vivo compression

摘要

In a general purpose, studies about effects of external mechanical strains on muscle aimed to investigate sore formation, rise of muscle pathologies by long term pressure application, impact damage, muscle fatigue (Piscione and Garnet 2006). Few studies concerning mammalian muscles have investigated twitch contraction under in vivo compression either on rat muscle fibre bundles using high hydrostatic pressure (Ranatunga and Geeves 1991), or on human biceps using a compressive cuff (Brown et al. 1997). Our purpose was to study the effect of in vivo compression on twitch contraction with a particular interest to the transverse force developed by compressed muscle.
