A process whereby force is generated within smooth 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. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. 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 stops, prevents or reduces the frequency, rate or extent of smooth muscle contraction. Any process that activates or increases the frequency, rate or extent of smooth muscle contraction. Any process that modulates the frequency, rate or extent of uterine smooth muscle contraction. Any process that increases the frequency, rate or extent of vascular smooth muscle contraction. Any process that modulates the frequency, rate or extent of a muscle system process, a multicellular organismal process carried out by any of the organs or tissues in a muscle system. Any process that modulates the frequency, rate or extent of smooth muscle contraction. Any process that modulates the frequency, rate or extent of muscle contraction of the hindgut, the posterior part of the alimentary canal, including the rectum, and the large intestine.
