Flight was recorded with two synchronized video cameras (60 Hz) and analyzed using DLT procedures. A second order polynomial function using the least square method was used to derive timc-displacement data of ball trajectory for each pitch. Estimated vertical acceleration during the flight was -4.5 (FB), - 12.9 (CB), -7.4 (SL), and -9.6 m/s^2 (FK), respectively. The mean ratio of final/initial velocity of the horizontal velocity of the pitch was 0.877 (FB), 0.864 (CB), 0.882 (SL), and 0.850 (FK). These results suggest that horizontal deceleration rather than vertical drop in the latter part of the flight is the unique characteristic of the forkball.", "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.25.1.13", "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": "SAKURAI, Shinji", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "IKEGAMI, Yasuo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "YAMAMOTO, Yuji", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "NUNOME, Hiroyuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "TERASHIMA, Toru", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "YABE, Kyonosuke", "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": "2023-03-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "njhpfs_25_1_13.pdf", "filesize": [{"value": "3.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 3700000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2005198/files/njhpfs_25_1_13.pdf"}, "version_id": "26e5e2b6-af85-468b-a70b-8d0e052e48b3"}]}, "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": "Trajectory of a pitched baseball : How and why does the forkball break downward?", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Trajectory of a pitched baseball : How and why does the forkball break downward?", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1679636128616"], "permalink_uri": "https://doi.org/10.18999/njhpfs.25.1.13", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-27"}, "publish_date": "2023-03-27", "publish_status": "0", "recid": "2005198", "relation": {}, "relation_version_is_last": true, "title": ["Trajectory of a pitched baseball : How and why does the forkball break downward?"], "weko_shared_id": -1}
