A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the hindgut. 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 hindgut is the posterior part of the alimentary canal, including the rectum, and the large intestine. [ http://purl.obolibrary.org/obo/UBERON_0001046 GOC:jl GOC:mtg_muscle ]
