fast-twitch skeletal muscle fiber contraction
fast-twitch skeletal muscle fiber contraction
A process in which force is generated within fast-twitch skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The fast-twitch skeletal muscle is characterized by fast time parameters, high force development and fatiguability.
