Any process that activates or increases the frequency, rate or extent of muscle contraction. Any process that activates or increases the frequency, rate or extent of fast-twitch skeletal muscle contraction. Any process that activates or increases the frequency, rate or extent of striated muscle contraction. A process whereby force is generated within striated 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. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope. Any process that modulates the frequency, rate or extent of twitch skeletal muscle contraction. Any process that modulates the frequency, rate or extent of striated muscle contraction. Any process that modulates the frequency, rate or extent of fast-twitch skeletal muscle contraction. A process whereby force is generated within 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 twitch skeletal muscle responds to neurostimulations with a contraction followed by a relaxation. A process whereby 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.
