In the experimental group, disuse muscle atrophy was induced by hindlimb suspension for two weeks, Upon termination of the suspension, these rats were made to run for 10, 30, or 90 min/day on a treadmill during the subsequent recovery period (2 wk). The soleus muscle weight-to-body weight ratio for the 90 min-group was significantly higher than that for the other experimental groups, but not different from that for the control group, indicating that this group had recovered as a result of exercise. No differences in cross-sectional area of muscle fiber or percentage distribution of muscle fiber type were observed among the experimental groups. Frequency distribution analysis of the cross-sectional area revealed apopulation of sma11-sized fibers with type II fiber in the experimental groups, indicating that exercise may cause transient muscle injury. These findings suggest that the effect of exercise during recovery from disuse muscle atrophy can't be controlled by only duration and that it is necessary to considerboth the effect of and muscle injury caused by exercise.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院医学系研究科活動能力回復学","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本理学療法士協会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110004009718/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは学会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11545224","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-3770","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_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山崎, 俊明"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"立野, 勝彦"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"灰田, 信英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"出口, 恵美子"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-YAMAZAKI-T-381.pdf","filesize":[{"value":"579.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-YAMAZAKI-T-381.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13000/files/ME-PR-YAMAZAKI-T-381.pdf"},"version_id":"6026bc37-7d71-4912-b8c0-31a1313374da"}]},"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":"運動負荷時間の違いがラット廃用性筋萎縮の回復過程に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"運動負荷時間の違いがラット廃用性筋萎縮の回復過程に及ぼす影響"},{"subitem_title":"Effect of Exereise Duration on Recovery from Disuse Atrophy in Rat Soleus Muscle","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"13000","relation_version_is_last":true,"title":["運動負荷時間の違いがラット廃用性筋萎縮の回復過程に及ぼす影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:11:45.771437+00:00"}
