One male collegiate tennis player participated in the study. The three-dimensional coordinates of reflective markers attached to the subject and his tennis racket were obtained from images acquired at 250 fps using a 12-camera motion capture system while the subject executed tennis serves. The findings are summarized as follows:\n1. Racket head velocity significantly decreased as the tennis serves were repeated.\n2. This decrease in racket head velocity with repeated tennis serves resulted from a\nreduction in the angular velocity of the wrist palmar flexion, which decreased the\nwrist joint-force-power that was transferred from the forearm to the hand.\n3. After fatigue, the radius of the shoulder internal rotation was increased by wrist\nflexion, and, as a result, the racket head velocity was improved by internal rotation.\n4. The elbow flexion caused by the increase of elbow flexion torque and the reduction of positive mechanical work produced by the shoulder joint force caused the racket head velocity to decrease at ball impact.","subitem_description_type":"Other"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13472135","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田邉, 智"},{"creatorName":"タナベ, サトル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANABE,  Satoru","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":"2017-05-12"}],"displaytype":"detail","filename":"119-144.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"119-144","url":"https://osu.repo.nii.ac.jp/record/1902/files/119-144.pdf"},"version_id":"75344851-aec8-41f0-a940-a3a2efeb80e2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"掌屈","subitem_subject_scheme":"Other"},{"subitem_subject":"内旋","subitem_subject_scheme":"Other"},{"subitem_subject":"肘の伸展","subitem_subject_scheme":"Other"},{"subitem_subject":"palmar flexion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"internal rotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"elbow extension","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"テニスサービスの打球数増加による体幹および上肢関節 運動の変化がラケット速度へ及ぼす影響について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テニスサービスの打球数増加による体幹および上肢関節 運動の変化がラケット速度へ及ぼす影響について"},{"subitem_title":"Effect of the Changes in the Upper Torso and Upper Limb Joint Movements by Repeated Tennis Service on the Racket Velocity","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["401"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-12"},"publish_date":"2017-05-12","publish_status":"0","recid":"1902","relation_version_is_last":true,"title":["テニスサービスの打球数増加による体幹および上肢関節 運動の変化がラケット速度へ及ぼす影響について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-06-20T13:27:29.027220+00:00"}
