obsolete cross bridge formation involved in regulation of the velocity of shortening in skeletal muscle contraction https://github.com/geneontology/go-ontology/issues/31254 true GO:0014871 OBSOLETE. The process in which actin and myosin interact, split ATP and generate force during skeletal muscle contraction. This process is one of the components of the regulation of the force of skeletal muscle contraction. biological_process This term was obsoleted because it is a pre-composed term that should be captured as a GO-CAM model.
