Any process that activates or increases the frequency, rate or extent of muscle contraction. Any process that modulates the frequency, rate or extent of muscle contraction. A process whereby force is generated within 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. Any process that increases the frequency, rate or extent of cardiac muscle contraction. Any process that activates or increases the frequency, rate or extent of fast-twitch skeletal muscle contraction. Any process that activates, maintains or increases the frequency, rate or extent of skeletal muscle contraction via the regulation of the release of sequestered calcium ion by sarcoplasmic reticulum into cytosol. The sarcoplasmic reticulum is the endoplasmic reticulum of striated muscle, specialised for the sequestration of calcium ions that are released upon receipt of a signal relayed by the T tubules from the neuromuscular junction. Any process that activates or increases the frequency, rate or extent of an organismal process, any of the processes pertinent to the function of an organism above the cellular level; includes the integrated processes of tissues and organs. 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 striated muscle contraction. Any process that activates or increases the frequency, rate or extent of tonic skeletal muscle contraction. Any process that activates or increases the frequency, rate or extent of slow-twitch skeletal muscle contraction.
