Throwing frequency was increased at one exercise, and the distance to the target was increased at the other exercise gradually at each 3 minutes, respectively. During the exercises energy expenditure was measured by analysis of expired gas, and external work i. e. kinetic energy of the ball which was given by subjects was calculated with video tape recording. Overall delta efficiency of skilled and unskilled players were not different significantly at both 2 exercises. This was caused by the reason that internal work was small but ball speed was large at skilled players. Hitting probability of unskilled players was decreased with the increase in throwing distance, but that of skilled players was maintained up to about 5m. In this range, net efficiency of skilled players was significantly higher than that of unskilled players. The difference was supposed to be derived from mastery of the throwing skill.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11189254","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13433954","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"松原, 周信","creatorNameLang":"ja"},{"creatorName":"マツバラ, チカノブ","creatorNameLang":"ja-Kana"},{"creatorName":"Matsubara, Chikanobu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"菊地, 紀子","creatorNameLang":"ja"},{"creatorName":"キクチ, ノリコ","creatorNameLang":"ja-Kana"},{"creatorName":"Kikuchi, Noriko","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000041171.pdf","filesize":[{"value":"883.7 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000041171.pdf","url":"https://kpu.repo.nii.ac.jp/record/4218/files/KJ00000041171.pdf"},"version_id":"1f805179-220b-4733-a1ca-8dbbb60ada5c"}]},"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"}]},"item_title":"バスケットボールのチェストパスにおける技能の水準と機械的効率の関係(人間環境学)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"バスケットボールのチェストパスにおける技能の水準と機械的効率の関係(人間環境学)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["360"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4218","relation_version_is_last":true,"title":["バスケットボールのチェストパスにおける技能の水準と機械的効率の関係(人間環境学)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-05-31T01:41:49.414407+00:00"}
