The purpose of this study was to examine the regulation of triceps surae muscle activation during DJs. Seven healthy subjects dropped from 3 different heights, and were asked to not rebound （landing only: LAND） or rebound with maximal effort （RJmax）. Joint angular data, ground reaction force and electromyography of the lower leg muscles were simultaneously recorded during each DJ. With higher drop heights, agonist muscle activities （medial gastrocnemius and soleus muscles） during the pre-activation phase were dramatically increased, while those did not show any differences during braking phase. The increased agonist muscle activation before touchdown（pre-activation） was significantly decreased during the following braking phase for regulation of low stiffness in the LAND. The agonist muscle activities during braking phase were increased with stiffness index of muscle-tendon unit from LAND to RJmax during constant drop height. However, the pre-activation of the agonist muscle was not increased while that of the corresponding antagonist tibialis anterior muscle was significantly increased from LAND to RJmax. During the following braking phase, the antagonist muscle activities were not increased. These results suggest that the effects of agonist muscle pre-activation are mainly for the impact of touchdown, and not for the regulation of landing or rebound. Consequently, the antagonist pre-activation and the agonist muscles activation of braking phase may play important roles to control motion after landing, and regulate stiffness.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14993/00000693","subitem_identifier_reg_type":"JaLC"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12576562","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-338X","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"新井, 彩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石川, 昌紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 章"},{"creatorName":"イトウ, アキラ","creatorNameLang":"ja-Kana"},{"creatorName":"ITO, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arai, Aya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishikawa, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-27"}],"displaytype":"detail","filename":"P21-28.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"P21-28.pdf","url":"https://mukogawa.repo.nii.ac.jp/record/699/files/P21-28.pdf"},"version_id":"039c0239-70d1-498d-9d98-b98ca8072256"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Pre-activation"},{"subitem_subject":"stretch-shortening cycle"},{"subitem_subject":"ARV"},{"subitem_subject":"landing"},{"subitem_subject":"drop jump"},{"subitem_subject":"Muscle-Tendon Unit（MTU）"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"異なるドロップ高からの着地における筋活動の調節","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"異なるドロップ高からの着地における筋活動の調節"},{"subitem_title":"Regulation of the muscle activation during drop landing and jump under various height","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["230"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-03-13"},"publish_date":"2013-03-13","publish_status":"0","recid":"699","relation_version_is_last":true,"title":["異なるドロップ高からの着地における筋活動の調節"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T12:57:43.216740+00:00"}
