Eight male subjects performed\ndrop jumping (DJ: typical stretch shortening\nmovement) from the height of 0.2m. During the downward phase, fascicles shortened by 7.1mm (10.6% relative to the length in the erect standing position) with 25.0mm (6.8%) of stretch in the tendinous structures although the muscle-tendon complex (MTC) lengthened by 17.0mm (4.0%) . During the upward phase, the fascicles shortened only by 3.1mm (4.7%) while the MTC rapidly shortened by 24.0mm (6.5%). Elastic energy stored in the tendinous structures during the downward phase (7.6 ± 0.45J) was partly provided from the work performed by the fascicles (2.6 ± 0.39J). In the following upward phase, 76% of the elastic energy\nstored in the tendinous structures (5.8 ± 0.6J) was reutilized, which accounted for 75% of the mechanical work performed by the MTC. The present results demonstrate that the fascicles operated not as a work generator, but as a force controller. Rapid recoil of the tendinous structures enhanced the shortening velocity of the MTC, which allowed the muscle fibers to behave in a quasi-isometric manner in the upward phase. In addition, it was suggested that potentiation of the contractile machinery or stretch reflexes may not be contributing to the motion generation during the DJ performed in this study.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"【論文／Articles】","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"明治学院大学教養教育センター"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12200206","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-8099","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KUROKAWA, Sadao"}],"nameIdentifiers":[{"nameIdentifier":"2840","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-03-07"}],"displaytype":"detail","filename":"karuchuru_2-1_9-21.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"karuchuru_2-1_9-21.pdf","url":"https://meigaku.repo.nii.ac.jp/record/1539/files/karuchuru_2-1_9-21.pdf"},"version_id":"39b0dca0-e4f8-4dd4-bc03-d19e87ae0c9d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ultrasonography","subitem_subject_scheme":"Other"},{"subitem_subject":"Muscle-tendon complex","subitem_subject_scheme":"Other"},{"subitem_subject":"Gastrocnemius","subitem_subject_scheme":"Other"},{"subitem_subject":"Elastic energy","subitem_subject_scheme":"Other"},{"subitem_subject":"Stretchshortening cycle","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Behavior of human m.gastrocnemius during explosive stretch-shortening cycle movement investigated by ultrasonography","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Behavior of human m.gastrocnemius during explosive stretch-shortening cycle movement investigated by ultrasonography"}]},"item_type_id":"2","owner":"3","path":["216"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-12"},"publish_date":"2017-07-12","publish_status":"0","recid":"1539","relation_version_is_last":true,"title":["Behavior of human m.gastrocnemius during explosive stretch-shortening cycle movement investigated by ultrasonography"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T18:32:01.591688+00:00"}
