This noise causes large inaccuracies when velocities and accelerations are determined by direct differentiation. Therefore, some form of additional data treatment, such as digital filtering, is essential. Though digital filtering is superior to reduce the noise, there occur serious problems in using this method. These are 1) difficulty to determine the cut off frequency of the filter objectively and 2) generation of terminal distortion on both ends of data by filtering. Utilizing a simulation and actual data analysis, methods to solve these problems were investigated. Results are as follows : (1) A spectrum analysis of the velocity or acceleration data derived from direct differentiation of non-filtered spatial data was helpful to decide the suitable cut off frequency of the filter. (2) A technique of \"finite difference followed by filtering\" decreased the terminal distortion, while other conventional techniques, such as often utilized \"filtering followed by finite defference\" method, were clearly inferior.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/njhpfs.8.1.95","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学総合保健体育科学センター","subitem_publisher_language":"ja"},{"subitem_publisher":"The Research Center of Health, Physical Fitness and Sports, Nagoya University","subitem_publisher_language":"en"}]},"item_9_source_id_7":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"0289-5412","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"桜井, 伸二","creatorNameLang":"ja"},{"creatorName":"SAKURAI, Shinji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"池上, 康男","creatorNameLang":"ja"},{"creatorName":"IKEGAMI, Yasuo","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-05-08"}],"displaytype":"detail","filename":"njhpfs_8_1_95.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2005973/files/njhpfs_8_1_95.pdf"},"version_id":"9208f2d6-2de3-460b-b3d0-2a9cbec3192d"}]},"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":"フィルムデータの平滑化法について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フィルムデータの平滑化法について","subitem_title_language":"ja"}]},"item_type_id":"40001","owner":"1","path":["1682990751904"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-05-08"},"publish_date":"2023-05-08","publish_status":"0","recid":"2005973","relation_version_is_last":true,"title":["フィルムデータの平滑化法について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-08T05:27:33.610965+00:00"}
