The data analyzed were all the challenge requested from 76 matches in volleyball competition in the 2016 Rio de Janeiro Olympics. The success rate of challenges was calculated from the number of successful challenges divided by the number of challenges for each type of play.\nAs results, the following findings were obtained:\n1) The total number of challenges was 400 times, the number of successful challenges (i.e., the number of errors in referee's judgment) was 163 times, and the success rate of challenges was 40.8%. There was no difference in these variables between men’s and women’s competitions.\n2) The number of successful challenges and the success rate of challenges for the blocker’s ball contact were higher than those for the other types of play, suggesting that it is one of the most difficult judgments for volleyball referees to determine the contact between the blocker and the ball.\n3) Regarding the judgment on the ball contact of the blocker, the frequency of judgment corrected from no touch to touch was larger than that corrected from no touch to touch. Regarding the judgment on ball in/out, the frequency of judgment corrected from ball out to ball in was larger than that corrected from ball in to ball out.\nThe present study revealed the types and situations of play which are likely to be erroneously judged in volleyball competition for the first time. These findings would be useful for improving the technique of referees from the viewpoint of using visual information and for the future application of video challenge system in volleyball.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本バレーボール学会"}]},"item_5_publisher_28":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_publisher":"The Japanese Society of Volleyball Research"}]},"item_5_relation_39":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://jsvr.org/archives/pdf/issue/19/jsvr19pp51-57.pdf","subitem_relation_type_select":"URI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本バレーボール学会"},{"subitem_rights":"複製などの著作物利用は、著作権法に示される私的使用の範囲内に限ります。"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-9524","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12363018","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"國部, 雅大"},{"creatorName":"コクブ, マサヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-15"}],"displaytype":"detail","filename":"jsvr_19_51.pdf","filesize":[{"value":"668.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jsvr_19_51","url":"https://tsukuba.repo.nii.ac.jp/record/43794/files/jsvr_19_51.pdf"},"version_id":"05ba81d2-8ff1-43f4-bbde-bd75487cbf87"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Olympics","subitem_subject_scheme":"Other"},{"subitem_subject":"video challenge system","subitem_subject_scheme":"Other"},{"subitem_subject":"ball contact","subitem_subject_scheme":"Other"},{"subitem_subject":"visual information","subitem_subject_scheme":"Other"},{"subitem_subject":"referee","subitem_subject_scheme":"Other"},{"subitem_subject":"オリンピック","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ビデオチャレンジシステム","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ボールコンタクト","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"視覚情報","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"レフェリー","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"チャレンジシステムの分析によるバレーボールのレフェリーにおける判定の正確性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"チャレンジシステムの分析によるバレーボールのレフェリーにおける判定の正確性に関する研究"},{"subitem_title":"A study on the judgment accuracy of volleyball referees by the analysis of challenge system","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["6156","5306"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-15"},"publish_date":"2017-11-15","publish_status":"0","recid":"43794","relation_version_is_last":true,"title":["チャレンジシステムの分析によるバレーボールのレフェリーにおける判定の正確性に関する研究"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:14:53.928503+00:00"}
