A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the body of stomach. 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 body of stomach is the part of the stomach that lies between the fundus above and the pyloric antrum below; its boundaries are poorly defined.
