Eight male skaters participated in a wind tunnel experiment, where air frictional forces (drag forces) under different skating postures were determined using a force platform (1 kHz). The skaters were videotaped with a digital video camera (60 fps)from a side by using a two-dimensional DLT method. The two-dimensional coordinates of the body were collected to calculate the segment angles (torso, thigh, and shank) in the sagittal plane. The torso, thigh, and shank angles in the normal skating posture were 11.0±5.2 deg, 27.5±9.4 deg, and 59.5±5.7 deg, respectively. Although the air frictional force in the normal skating posture (17.3±2.1 N) was significantly smaller than those in a high skating posture (22.8±2.3 N, p＜0.001) and the highest skating posture (28.8±2.4 N, p＜0.001), it was not significantly different than those in a low skating posture (15.4±0.9 N) and the lowest skating posture (14.7±1.1 N). This indicates that the air frictional force remarkably increases with the height of skating posture. Moreover, although in a low skating posture, skaters experienced great stress on their lower limbs, the decrease achieved in the air resistance by greatly decreasing the height of skating posture was remarkably small. Thus, the normal skating posture presented in this study would be rational skating posture for minimizing the air resistance and maintaining the skating movement.","subitem_description_type":"Abstract"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34349/00000849","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本女子体育大学"}]},"item_3_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00192838","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02850095","subitem_source_identifier_type":"ISSN"}]},"item_3_textarea_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_textarea_value":"日本女子体育大学（講師）"},{"subitem_textarea_value":"日本体育大学女子短期大学部（准教授）"},{"subitem_textarea_value":"国立スポーツ科学センタースポーツ科学研究部"},{"subitem_textarea_value":"財団法人日本スケート連盟"}]},"item_3_version_type_18":{"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":"湯田, 淳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青柳, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高松, 潤二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山辺, 芳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 恵一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yuda, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyanagi, Toru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takamatsu, Junji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamanobe, Kaoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Keiichi","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":"2019-08-21"}],"displaytype":"detail","filename":"nichijo_kiyo39-02.pdf","filesize":[{"value":"386.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nichijo_kiyo39-02.pdf","url":"https://jwcpe.repo.nii.ac.jp/record/855/files/nichijo_kiyo39-02.pdf"},"version_id":"e89e437e-4c50-40af-bb88-3aad3f4fd500"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"speed skating","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"air frictional force","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"skating posture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wind tunnel experiment","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":"スピードスケートにおける滑走姿勢の相違が空気抵抗力に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スピードスケートにおける滑走姿勢の相違が空気抵抗力に及ぼす影響"},{"subitem_title":"The influence of air resistance on different skating postures in speed skating"}]},"item_type_id":"3","owner":"4","path":["98"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-27"},"publish_date":"2016-01-27","publish_status":"0","recid":"855","relation_version_is_last":true,"title":["スピードスケートにおける滑走姿勢の相違が空気抵抗力に及ぼす影響"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-07-05T07:53:12.810282+00:00"}
