[Subjects and Method] The subjects were 9 healthy adults. There were 4 exercise tasks of constant work and pedaling rates, and 2 tasks of changing the pedaling rate (but not work rate) during exercise. Each of the tasks were performed in 3 contiguous sets, and we examined and compared the changes in oxygenated hemoglobin (oxyHb) at 5-second intervals from the start of exercise. [Results] In the 4 tasks of constant work and pedaling rates, the change in oxyHb over 5-10 seconds from\nthe start of exercise was significantly higher than over 0-5, 10-15 and 15-20 seconds, and the transient increase in\noxyHb decreased despite the continuation of exercise. In the 2 tasks in which the pedaling rate was changed, we found that oxyHb gradually decreased after the initial increase at the start of exercise, but increased again with increase of the pedaling rate. [Conclusion] We revealed the activity of the lower limb area of the primary motor cortex during bicycle ergometer exercise. We also demonstrated that the effect of changing the pedaling rate during exercise is to increase the blood flow in the lower limb area of the primary motor cortex.","subitem_description_type":"Abstract"}]},"item_19_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"理学療法科学学会"}]},"item_19_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10472896","subitem_source_identifier_type":"NCID"}]},"item_19_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341-1667","subitem_source_identifier_type":"ISSN"}]},"item_19_text_1":{"attribute_name":"Title in Japanese","attribute_value_mlt":[{"subitem_text_value":"自転車エルゴメーター駆動時における大脳皮質活動 : 近赤外線分光法による検討"}]},"item_19_text_2":{"attribute_name":"タイトル（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Human Motor Cortex Oxygenation Measured by NIRS during Ergometer Exercise"}]},"item_19_text_47":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_19_text_48":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_19_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":"中林, 美代子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大西, 秀明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古沢, アドレアネ 明美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakabayashi, Miyoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Onishi, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furusawa, Adreane A","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":"2019-10-30"}],"displaytype":"detail","filename":"055_nakabayashi_m.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"055_nakabayashi_m.pdf","url":"https://nsg.repo.nii.ac.jp/record/4100/files/055_nakabayashi_m.pdf"},"version_id":"292e4552-ce82-45ad-bd28-e476ef0ed0ed"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"近赤外線分光法","subitem_subject_scheme":"Other"},{"subitem_subject":"自転車エルゴメーター","subitem_subject_scheme":"Other"},{"subitem_subject":"大脳感覚運動野","subitem_subject_scheme":"Other"},{"subitem_subject":"fNIRS","subitem_subject_scheme":"Other"},{"subitem_subject":"bicycle ergometer","subitem_subject_scheme":"Other"},{"subitem_subject":"sensory motor cortex","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":"自転車エルゴメーター駆動時における大脳皮質活動 : 近赤外線分光法による検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自転車エルゴメーター駆動時における大脳皮質活動 : 近赤外線分光法による検討"},{"subitem_title":"Human Motor Cortex Oxygenation Measured by NIRS during Ergometer Exercise","subitem_title_language":"en"}]},"item_type_id":"19","owner":"1","path":["13"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-30"},"publish_date":"2013-08-30","publish_status":"0","recid":"4100","relation_version_is_last":true,"title":["自転車エルゴメーター駆動時における大脳皮質活動 : 近赤外線分光法による検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T12:19:05.678509+00:00"}
