SL was also computed by dividing walking speed by SF. The V・O2 during decremental−speed walking was significantly greater compared to that during incremental−speed walking at corresponding speeds. The SF and SL could be expressed as a function of speed by SF＝13.18 and SL＝0.076 , respectively, regardless of the different modes of walking with respect to speed. To estimate the V ・O2 during walking at different speeds, the results of the increments and decrements were combined by averaging them with respect to speed（V・O2＝1.454×10−4v2−6.5×10−3v＋0.663, r＝0.999, n＝7）. In a mathematical model of the cardiorespiratory system, the average values of V・O2 at a given speed, even though there were on− and off−phase responses, could be predicted within 7.4％ of the theoretical steady−state value. These results suggest that the V ・O2 against walking speed can be estimated by averaging the responses between the increments and decrements of moderate speeds. This could improve exercise tests for V・O2 estimates in terms of time and money. In addition, by using the closerelationship between SF and v, V・O2 can be also expressed as a function of SF.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Life Science Publishing"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10043845","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-8020","subitem_source_identifier_type":"ISSN"}]},"item_2_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":"Takahashi, Tatsuhisa"}],"nameIdentifiers":[{"nameIdentifier":"500","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yanagita, Hirotaka"}],"nameIdentifiers":[{"nameIdentifier":"501","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Niizeki, Kyuchi"}],"nameIdentifiers":[{"nameIdentifier":"502","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Shuoyu"}],"nameIdentifiers":[{"nameIdentifier":"503","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuo, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"504","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"505","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okada, Akiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"506","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuwayama, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"507","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Natsui, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"508","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-13"}],"displaytype":"detail","filename":"TR_30_2_219.pdf","filesize":[{"value":"383.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TR_30_2_219.pdf","url":"https://kutarr.kochi-tech.ac.jp/record/138/files/TR_30_2_219.pdf"},"version_id":"b9d54cbe-d715-4932-a7ba-1c76278dfbf2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Walking speed","subitem_subject_scheme":"Other"},{"subitem_subject":"Step length","subitem_subject_scheme":"Other"},{"subitem_subject":"Step frequency","subitem_subject_scheme":"Other"},{"subitem_subject":"Walking exercise","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Economical estimates of oxygen uptake as a function of gait parameters for an ambulatory monitoring system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Economical estimates of oxygen uptake as a function of gait parameters for an ambulatory monitoring system"}]},"item_type_id":"2","owner":"2","path":["5"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-10-18"},"publish_date":"2011-10-18","publish_status":"0","recid":"138","relation_version_is_last":true,"title":["Economical estimates of oxygen uptake as a function of gait parameters for an ambulatory monitoring system"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T13:43:39.117692+00:00"}
