Atherosclerosis develops as the functioning of vascular endothelial cells diminishes. When blood flows rapidly through those endothelial cells, they release a vasodilator called nitric oxide （NO）．NO relaxes smooth muscle in the tunica media and it dilates blood vessels. In other words, blood vessels stiffen and lose their elasticity depending on the level of NO. Research over the past few years has suggested that performing an exercise with a grip strength of about 30% may decrease blood pressure. However, no studies thus far have examined the decrease in blood pressure as a result twisting an object. Moreover, the relationship between twisting motion and grip strength has yet to be determined. The current authors hypothesized that gripping and twisting action might have similar effects. Accordingly, the aims of the current study were to observe muscle activity and hemodynamics during repeated twisting action and to ascertain the relationship between grip strength and twisting action. Thus, left and right grip strength was measured in a standing position, and maximum twisting strength was measured in a seated position while twisting a twist bar in the opposite direction with the right and left hands. In addition, grip strength of the right hand was measured in a seated position, and maximum twisting strength was measured with a twist bar. Muscle activity of the brachioradialis and flexor carpi ulnaris was measured during that action, and the relationship between muscle activity and twisting action was examined. Results indicated that twisting action was correlated with grip strength. Grip strength was correlated with the level of muscle activity of the flexor carpi ulnaris and the brachioradialis during twisting action. The appropriate pace for twisting motion was not evident, so the pace of twisting was examined. Subjects performed 40, 50, or 60 twists for 1 min continuously, rested for 1 min, and then performed the twisting action for another min. Before and afterwards, blood flow volume around the flexor carpi ulnaris and the brachioradialis was measured, and blood pressure was also measured. Results indicated that blood flow volume tended to increase after twisting action at all 3 paces. Blood flow volume around the brachioradialis in particular was significantly greater at a pace of 60 twists per min. Moreover, blood flow volume in the vicinity of the flexor carpi ulnaris increased significantly at all 3 paces. Systolic blood pressure increased after twisting action at all 3 paces. In contrast, diastolic blood pressure tended to decrease at all 3 paces, and it was significantly lower particularly at a pace of 40 twists per min. Based on these findings, repeatedly performing continuous twisting action alternately activates the brachioradialis and the flexor carpi ulnaris. As a result, blood flow volume increases and the stretchability of the vascular wall increases, presumably causing diastolic blood pressure to decrease.","subitem_description_type":"Abstract"}]},"item_10002_description_180":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10002_heading_148":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"研究","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Study","subitem_heading_language":"en"}]},"item_10002_publisher_169":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国士舘大学体育・スポーツ科学学会"}]},"item_10002_source_id_170":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-9316","subitem_source_identifier_type":"PISSN"}]},"item_10002_source_id_172":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10474825","subitem_source_identifier_type":"NCID"}]},"item_10002_subject_177":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"491.197","subitem_subject_scheme":"NDC"}]},"item_10002_textarea_160":{"attribute_name":"著作関係者詳細","attribute_value_mlt":[{"subitem_textarea_value":"Hiroo YAMAKAWA and Masamichi ANDO ： Murata Manufacturing Co.,Ltd.
