The exercise time (sec) of the incremental ergometer exercise, exercise intensity at exhaustion (watt), maximal oxygen uptake (ml per kg per min), maximal heart rate (beats per min) and the following serum parameters were measured before ingestion, 1 h after ingestion, just after exhaustion and 15 min after exhaustion: ornithine, ammonia, urea, lactic acid and glutamate. All indices on maximal aerobic capacity showed insignificant differences between both the conditions.Results:Plasma ammonia concentrations just after exhaustion and at 15 min after exhaustion were significantly more with ornithine ingestion than with placebo. Plasma glutamate concentrations were significantly higher after exhaustion with ornithine ingestion than with placebo.Conclusions:It was suggested that, although the ingestion of L-ornithine hydrochloride before the exercise cannot be expected to improve performance, it does increase the ability to buffer ammonia, both during and after exercise. © 2010 Macmillan Publishers Limited All rights reserved.", "subitem_description_type": "Abstract"}]}, "item_4_description_5": {"attribute_name": "提供者所属", "attribute_value_mlt": [{"subitem_description": "金沢大学人間社会研究域人間科学系", "subitem_description_type": "Other"}, {"subitem_description": "Fukui National College of Technology", "subitem_description_type": "Other"}]}, "item_4_publisher_17": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_4_relation_12": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1038/ejcn.2010.149", "subitem_relation_type_select": "DOI"}}]}, "item_4_source_id_11": {"attribute_name": "NCID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10667838", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0954-3007", "subitem_source_identifier_type": "ISSN"}]}, "item_4_version_type_25": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Demura, Shinichi"}], "nameIdentifiers": [{"nameIdentifier": "168", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "20155485", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://kaken.nii.ac.jp/ja/search/?qm=20155485"}, {"nameIdentifier": "20155485", "nameIdentifierScheme": "研究者番号", "nameIdentifierURI": "https://nrid.nii.ac.jp/nrid/1000020155485"}]}, {"creatorNames": [{"creatorName": "Yamada, Takayoshi"}], "nameIdentifiers": [{"nameIdentifier": "3302", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaji, Shunsuke"}], "nameIdentifiers": [{"nameIdentifier": "3303", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Komatsu, Miho"}], "nameIdentifiers": [{"nameIdentifier": "3304", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Morishita, Koji"}], "nameIdentifiers": [{"nameIdentifier": "3305", "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": "2017-10-02"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ED-PR-DEMURA-YAMADA-1166.pdf", "filesize": [{"value": "200.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 200600.0, "url": {"label": "ED-PR-DEMURA-YAMADA-1166.pdf", "url": "https://kanazawa-u.repo.nii.ac.jp/record/565/files/ED-PR-DEMURA-YAMADA-1166.pdf"}, "version_id": "8e0c6f9a-c73c-4004-9ee7-68db6ae7315a"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "aerobic exercise", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ammonia metabolism", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fatigue recovery", "subitem_subject_scheme": "Other"}, {"subitem_subject": "L-ornithine hydrochloride", "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": "The effect of L-ornithine hydrochloride ingestion on performance during incremental exhaustive ergometer bicycle exercise and ammonia metabolism during and after exercise", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "The effect of L-ornithine hydrochloride ingestion on performance during incremental exhaustive ergometer bicycle exercise and ammonia metabolism during and after exercise"}]}, "item_type_id": "4", "owner": "3", "path": ["16"], "permalink_uri": "http://hdl.handle.net/2297/25434", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-10-02"}, "publish_date": "2017-10-02", "publish_status": "0", "recid": "565", "relation": {}, "relation_version_is_last": true, "title": ["The effect of L-ornithine hydrochloride ingestion on performance during incremental exhaustive ergometer bicycle exercise and ammonia metabolism during and after exercise"], "weko_shared_id": -1}
