本研究では、2009年1月に改正されたIJF試合審判規定が柔道競技に及ぼした影響を分析・検証を行なった。その上で、試合審判規定改正の世界柔道の戦術内容に関する最新の動向を探ることを目的とした。<BR>研究方法は、収録された映像を基に2008年フランス国際柔道大会及び2009年グランドスラム・パリ国際柔道大会の競技内容を比較した。試合数は両年合わせて476試合であった。競技分析を行う上で、項目を作成した。作成した項目については、「競技分析シート2009」に競技内容を入力するものとした。<BR>組み手については、釣り手・引き手ともに持った状態で施技を行う「充分」が0.1%水準で有意な増加が認められた。また、「ズボンを直接握る」ことへの反則適用から、施技者及び相手も施技時に「脚」を持つという戦術は有意な減少が認められた。さらに、施技する際の姿勢も前傾姿勢状態からの施技は5%水準で有意な減少が認められた。<BR>ポイント取得の技術内容や組み手戦術において改正前と比較した結果では、「脚」を持つ戦術に依存しないことで「襟」「袖」を持った状態で施技可能な技術に移行するという望ましい傾向となった。<BR>今回の改正によって懸案事項となっていた点が改善される傾向にあり、IJF試合審判規定改正が影響のあるものであったと考えられたが、「肩車」にみられるような「脚」を持つ技に対する依存は未だ存在している。そのため、2010年にさらなる試合審判規定の改正につながったものと推察する。

The purpose of this study was to investigate the cardiac dimensions and the influences of Kyudo practice in the function of the left ventricle and responses of cardiac function during shooting. The subjects were 14 shooters whose ages were 63-85 years (the average 68.8 years old) and even now they take part in formal Kyudo matches. Total body fat was assessed by the skinfold caliper method. The left venticular structure and function were measured using M-mode echocardiography and ECG during shooting were measured by the telemeter method. Results obtained were as follows.Subjects averaged 161.9 cm in height,59.7 kg in weight and 123.4 mmHg in systolic blood pressure. Time for shooting was about 30 seconds on the average, but the shortest time was 15 seconds, and the longest was 50 seconds. There were arrhythmia in 3 subjects at rest ECG. However, there were no differences in the ecocardiographic data between shooters and normal subjects. Arrhythmia disappeared in two subjects during shooting. The heart rate during shooting averaged 110 b/min, but one shooter recorded 180 b/min at maximal level.In summary, Kyudo practice is not so hard for old age shooters, but there is possibility that it builds up blood pressure, because it needs strong muscle activity during shooting. Therefore, old shooters must always take care of their medical condition.

IJFは2001年までは「判定方式」,2002年からは「ゴールデンスコア方式」を採用している。本研究は,2000年から2003年までの4年間に国際柔道連盟が主催した4大会を対象として,試合終了時に両試合者のスコアが同一であった試合の分析を試みた。2000年世界Jrナブール大会と2001年世界選手権ミュンヘン大会,全1,356試合の中で「判定」によって勝敗が決したのは73試合(5,4%)であった。2001年世界Jr済州島大会と2003年世界選手権大阪大会,全1,285試合の中で「GS」によって勝敗が決したのは42試合(3.3%)であり減少がみられた。「判定」によって勝敗が決した73試合を施技ランクB,Cおよび組み手主導権の3項目で比較した結果,審判員の判定が3対0の時にプラスポイントが確認された選手が勝ちとなったのは73,8%であった。一方,2対1の時はプラスポイントでの勝ちが41.9%と減少がみられたことから,全員一致の判定の困難さが窺える。同様の手法で「GS」に入る前の試合分析から,「GS」への移行が妥当と判断されたのは11試合(26.2%)であり,残りの31試合(73.8%)は項目比較によって優劣に差がみられた。「GS」導入によって試合時間は「判定方式」に比べて長くなるが,「判定」に対する「GS」の試合時間比は4分の試合で1.43倍増に対して,5分では1.28倍と減少が認められた。「GS方式」の導入によって,試合終了時に同一スコアとなる試合が激減した。また,実質上の試合時間を抑制する傾向が窺え,延長時間の問題も許容範囲であると言える。「GS」による試合は,罰則よりもポイント取得によって勝敗が決する方向にあり,勝負判定の客観化を推進するためには有効な改正であった。

The aim of this study is to clarify as much as possible the process of formation of the Jikishinkage-ryū, and by comparing that to the lineage and transmission from after its formation, to show how it has changed. Specifically, we verified whether the lineage and transmission mentioned in the scrolls written after the Jikishinkage-ryū's formation agree with those in the formation process. First, we examined the lineage and transmission in the scrolls written after the formation of Jikishinkage-ryū, and analyzed the formation process to clarify rewritten points in its lineage. We clarified the following six points:<BR>1.Yamada Heizaemon Mitsunori referred to himself as the second generation head of Jikishinseitō-ryū, not Jikishinkage-ryū. Therefore, it is after Naganuma Shirōzaemon Kunisato that Jikishinseitō-ryū was renamed Jikishinkage-ryū. This means there is a discrepancy between the period of the Jikishinkage-ryū's formation and its transmission.<BR>2.Multiple discrepancies regarding names and meanings can be spotted between historical materials written by the people mentioned in the lineage of Jikishinkage-ryū, and the transmission mentioned in the scrolls written after Jikishinkage-ryū was formed. This indicates that parts of the transmission were rewritten after the formation of Jikishinkage-ryū.<BR>3.It is in the "Jikishinkage-ryū Mokuroku Kudensh" (Catalogue of techniques and oral transmission of Jikishinkage-ry) by Naganuma Shirōzaemon Kunisato that Matsumoto Bizen-no-Kami was first recognized as the founder of Jikishinkage-ryū.<BR>4.The Enpi kata of Shinkage-ryū that originates from Kage-ryū can also be confirmed in the catalogue of techniques of Shinshinkage-ryū, although written with different kanji. Therefore, Shinshinkage-ryū can be said to have been affected by Kage-ryū via Shinkage-ryū.<BR>5.The name and meaning of each school (ryū) found in the lineage of Jikishinkage-ryū were interpreted with the consideration that the tradition bestowed by the deity of martial arts was inherited from generation to generation. This was from Matsumoto Bizen-no-Kami, the founder, to Yamada Heizaemon Mitsunori, who changed the name of the school to Jikishinkage-ryū.<BR>6.It is after Naganuma Shirōzaemon Kunisato that the colophon "Kashima Shinden," which shows that the style was bestowed by the deity Takemikazuchi, started to be used. It is also after Kunisato that Takemikazuchi was recognized as the originator of the school.

The compilation of the Dainihonteikoku Kendo-Kata has undergone 3 stages of “Sketch-Draft-Codification. ” In this paper, the original texts of these stages are compared and scrutinized concerning when, what and how amendments were added, and furthermore tendencies in the nature of the amendments were discussed, as well as its implications.In the evolution from the sketch to the draft, it seems the chief investigators and the investigators had question-and-answer sessions and exchanged views, and then, based on the results the chief investigators, re-examined the sketch to make amendments.For the purpose of organizing a unified Teikoku-Kendo-Kata transcending schools, organizing work is thought to have been encouraged by placing special emphasis on the basic concept, overall picture and comprehensive constitution of the Teikoku-Kendo-Kata. In addition, because it was governed by the chief investigators' mastery of the art of kendo, theory on techniques, and profound perception of the Teikoku-Kendo-Kata, the details of the sketch were not regarded as matters of particular importance. Consequently, in the work from the sketch to the draft, the Kodachi-Kata was settled on as not to be amended, and a total of 17 items, including 2 of the basic,5 of Tachiai and 10 of Tachi-Kata, as items to be amended.From the draft to the codification, through the deliberations of the Teikoku-Kendo-Kata Investigation Committee,6 amendments were adopted at first. Afterwards, as a result of the chief investigators' and the investigators' practicing the Teikoku-Kendo-Kata, minor differences became regarded as problems and amendments were added owing to the necessity of having more precise explanation for the sake of instruction. Finally, in the process of progression from the draft to codification, amendments were added for the first time to the Kodachi-Kata, and a total of 27 amendment items, containing 4 of the basic,4 of Tachiai,12 of Tachi-Kata and 7 of Kodachi-Kata items plus 6 items by the Teikoku-Kendo-Kata Investigation Committee's decisions, were added before release of the codification by the management office of the Butoku-Kai.
