The purpose of this study was to obtain the fundamental data of impact force on the Shomen-Uchi movement in Kendo. Four Kinds of Shomen-Uchi movements were analyzed by motion analysis system using the video tape recorder and impact force was measured simultaneously. The subjects for this study were 5 male Kendo players,33 to 42 years of age, with 20 to 30 years of training experience and 5 to 7dan degree.The results were summarized as follows:1. The downward maximum magnitude of impact force on movement A was greatest among four kinds of Shomen-Uchi movements (movement A: 144.41±41.07Kgw, movement B 144.25±35.78Kgw, movement C: 120.80±36.74Kgw, movement D: 127.81±32.23Kgw).2. The forward maximum magnitude of impact force on movement C was greatest among four kinds of Shomen-Uchi movements (movement A: 46.45±15.48Kgw, movement B: 61.45±20.90kgw, movement C: 80.80±24.05Kgw, movement D: 74.93±17.96Kgw).3. It was shown that the larger the maximum Shinai angle (the angle between Shinai and horizontal line) on the phase of backswing of Shinai is, the more the maximum magnitude of impact force (Fz) of the Shomen-Uchi movement increases.4. At the impact, a significant relationship between the trunk angle (the angle between trunk and horizontal line) and the forward impact force was seen.5. In the phase of downswing of Shinai on the Shomen-Uchi movement, a significant relationship between the impact force (Fz) and the downward maximum velocity of the top of Shinai was observed.

The purpose of this study is to research on the features of training and inter-disciplinary match characteristics in the three groups: the Naganuma, the Fujikawa and the Odani group. These three groups belonged to Jikishinkage-ryu kenjyutsu school and engendered different training styles. We analyzed the inter-disciplinary matches and the lineage of their kata. We also examined their view on kenjyutsu which, we considered, caused their characteristic features. The conclusions of this study are as below. 1.The Naganuma group adopted mainly jyodan posture to do uchikomi in the matches. Eight kinds of kata were practiced in the Naganuma group. 2.We consider that there were two reasons of their frequent adoption of jyodan posture in the matches: one was they frequently used shikake-waza and the other was they considered that the jyodan posture was convenient to deal with opponent’s actions. These characteristics developed the idea of attaching great importance to jyodan in the Naganuma group. They did not neglect kata practice even in the late Edo period when inter-disciplinary matches flourished. 3.As in the Naganuma group, jyodan was also adopted frequently in the Fujikawa group in their inter-disciplinary matches. Since the days of Saito Akinobu, five kinds of kata were practiced. 4.Fujikawa Seisai established the disciplinary system of Fujikawa group in the late Edo period. He criticized that the shinai-uchikomi-geiko stuck too much to winning and emphasized mental training. He insisted that the kata practice was effective in mental training. 5.In the Odani group, jyodan posture was not adopted. It is recorded that Odani Seiichiro adopted only seigan and gedan postures in the matches in Tempo era. As to kata practice only Hojyo is handed down in the Odani group and To-no-kata was trained in shinai-uchikomi-geiko. 6.Odani criticized the division of kenjyutsu into school names and insisted the importance of inter-disciplinary matches to develop one’s strong points and make up for the weak points. The trend as from Tempo period of Tsuki- techniques with a long Shinai was one of the reasons that Odani changed the traditional jyodan posture of Jikishinkage-ryu to seigan posture.

The body that oversees judo in Japan, the All Japan Judo Federation, has faced successive scandals involving violent incidents and fatal accidents which have served to give rise to social criticisms of its coaching practices. In April 2013, the organization launched a Certified Judo Coaching Qualification System in order “to improve coaches’ qualities and coaching ability, to enhance public trust in coaching practice, and to ensure coaches’ status.”Conversely, another judo powerhouse, the Fédération Française de Judo, Jujitsu, Kendo et Disciplines Associées (FFJDA), had defined professional judo qualifications, thereby establishing a national coaching qualification system, in a national sports-related law enacted in 1955.Although the differences between the Japanese and French social systems preclude any simple comparison, a number of experts have recommended the FFJDA coaching qualification system as a model for Japan. In 2008, the FFJDA introduced a new qualification system comprising six stages, such as the Diplôme d’Etat de la Jeunesse, de l’Education Populaire et du Sport (DEJEPS), and established an even more thorough policy for coaching training.The FFJDA is home to a variety of approaches, including a rigorous national examination system that allows coaching trainees to take an examination after a long period of training, a tutorial system (tuteur), a reciprocal exchange system (dispositifs de formation en alternance) and a screening system that leads to trainee certification. This has resulted not only in zero fatal accidents among judoka,but also in increased enrollment in the sport as well as an improvement in competitive ability, as reflected in France’s second-place ranking in judo at the 2012 London Olympics. The FFJDA system may thus serve as a useful case study for Japan, which is seeking to enhance its own coaching qualification system.

We noticed “Hokushin Ittoryu”, among several kenjutsu schools, which tried to re-build the sustem of techniquesa nd constracted them analytically. But in this essay, we have examinedt he kenjutesu-theory of Sugane Kubota who was a contemporary of Shusaku Chiba (the founder of “Hokushin Ittoryu”) and left enormous writings. Particularly we have studied, from the viewpoint of the history of athletic techniques, the features of the fundamentals of techniques which are the basis of the sustem of techniques.As a result, we have found the two faces; one is the part which tried to build the sustem of techniques consciously, that is, the part which changed from pre-modern (Edo era) kendo into modern (Meiji era) one, and the other in the part which could not get rid of the traditional “Kata-kenjutsu”.The results of the former are as follows(1) Not only feet position but also posture was right in the opposition to the opponent, and the direction of the sword was straight to the center of the opponent.(2) “Te-no-uchi in striking was similar to “pushing-cut” rather than “pulling-cut”.(3) The course of striking from the front along the central line to the opponent was proposed more mainly than from the right or left side. And continuous strikings were encouraged. The results of the latter are as follows:(1) The position of the sword was limited to the three; “jodan-no-kamae” “chudan-no-kamae”, and “gedannokamae”. And jodan-no-kamae”, in which the height of the point of the sword is fixed between the nose and mouth of the opponent, was the most basic.(2) The footwork was “ayumi-ashi” (walking step).(3) We guessed that swinging up was done without changing the condition of holding sword of the first posture.(4) The elbow joints were stretched more forward in holding the sword than modern kendo.(5) The follow-through of weight transfer after striking was not made unlike the present kendo, and it was directed to return to the former position soon.(6) “Kanemen-Zuki” was adopted, which was widely used in spear-fighting. It showed a tendency to the techniqueso f practical and comprehensivem ilitary arts. Thus, Kubota's kenjutsu-theory has some characteristics of the transitional age from pre-modern to modern theory. But it does not reach the stage which breaks with the traditional “kata-kenjutsu” and constructs the system of techniques.

The All-Japan Judo Championships (AJJC) is an open-weight tournament for determining the best judoka in Japan. The AJJC has been held under the Kodokan Judo Refereeing Rules (KDK Rules) since 1951. In 2011, the All-Japan Judo Federation (AJJF) introduced the International Judo Federation Refereeing Rules (IJF Rules), which were formulated to facilitate more dynamic judo (increased wins by <i>ippon</i>, decreased wins by judges' decisions, and decreased <i>mate</i>-time). Although the IJF Rules has facilitated dynamic judo in international competitions, their effects on the competition contents in the AJJC are still unknown. Here, we aimed to clarify whether the introduction of the IJF Rules facilitated dynamic judo in the AJJC.<BR>The 221 judo matches in the AJJC from 2008 to 2013 were separated into two groups, the tournaments following the KDK Rules (2008-2010) and those following the IJF Rules (2011-2013). Their data were extracted from the AJJC records by<i> Judo</i>, the official Kodokan journal, and from the match videos recorded by the AJJF. We analyzed the proportions of winning contents (wins by <i>ippon</i> or superior performance), winning methods (points from techniques or penalties, or judges' decisions), techniques for getting points (<i>te-waza, koshi-waza, ashi-waza, sutemi-waza, </i>or<i> katame-waza</i>) and the <i>mate</i>-time for each match. A chi-square test and an independent <i>t</i>-test were used to perform statistical analyses, and for each test, statistical significance was assumed at <i>P</i> value < 0.05.<BR>For the winning methods of the IJF Rules' and the KDK Rules' tournaments, the proportion of points from techniques (60.4% vs. 53.6%) and points from penalties (23.4% vs. 15.5%) showed no differences, but the proportion of wins by judges' decisions in the IJF Rules' tournaments was significantly lower than in the KDK Rules' tournaments (16.2% vs. 30.9%) (P < 0.05). Furthermore, the <i>mate</i>-time in the IJF Rules' tournaments was significantly shorter than in the KDK Rules' tournaments (77 s vs. 105 s) (P < 0.01). However, the winning contents and techniques for obtaining points showed no differences between the IJF Rules' and the KDK Rules' tournaments.<BR>We confirmed for the first time that the IJF Rules did not affect the winning contents and techniques for getting points, but decreased the proportion of judges' decisions and <i>mate</i>-time in the AJJC. These findings suggest that the IJF Rules partially facilitated dynamic judo in the AJJC.

The purpose of this study was to investigate the effect of lunge training on the striking ability of kendo players. Twelve university kendo players were assigned to either a training (n=6) or a control (n=6) group. The subjects in the training group performed lunge training three times a week for four weeks. After this training period, the pull-speed of the left leg during striking (p<0.01), the forward step distance of the right foot, maximal ground reaction force, maximal leg extension power, and the greatest leg split distance (p<0.05) all increased significantly in the training group. This study demonstrated that lunge training was effective in increasing the striking ability (i.e. increasing the pull-speed of the left leg after a strike) of kendo players.

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。<br>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。<br>「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。<br>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。<br>「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 Taihei-Shinkyo-Ryu (Kenjyutsu School) was founded by Wakana Shinkyosai, a masterless Samurai (Ronin), in 1778. This study aimed at explaining the situation behind Taihei-Shinkyo-Ryu, one of the Military Arts schools, among Hachioji-Sennin-Doshin.Results are summarized as follows:1. At the beginning of the. Edo Period, a group of Ronin (who were the last Takeda followers from the Kai District), were deployed at the crucial points in Hachioji for the defense of the Edo Castle by the Tokugawas. They were composed of three classes (Senninkashira, Kumikashira and Hiradoshin), and had to practice military arts.2. After the Kansei Era, the Tokugawas encouraged Sennin-Doshin to practice martial arts, and at that time Wakana Shinkyosai taught his philosophy to Hachioji-Sennin-Doshin.In case of Hachioji-Sennin-Doshin, the number of students was as follows: (for example, in case of Wakana Seishinsai >Shinkyosai's son< ) Senninkashira had 16, Kumikashira 11 and Hiradoshin 36.In this way, members from all classes practiced Taihei-Shinkyo-Ryu.3. The best student of this school was Shiono Tekisai, from Kumikashira. He spread the school philosophy to all classes of Sennin-Doshin. For example, during every winter, he practiced martial arts early in the morning with his students for about 50 days. The Dojo (practicing hall) was in the open air. It was so cold that they got their hands chapped, but they devoted themselves to practicing. Then, his Dojo came to be supported by Senninkashira. And some of students were selected to demonstrate Kenjyutsu in front of the Tokugawa Shogun and were given awards.4. The philosophy was derived from Confucianism. The parents of students needed it for the education of their children. They wanted their children to become the students (Nyumon) at the age of 16.5. Many Hiradoshin who lived in the village were farmers. So they harbored ill feeling toward Samurai who lived near the Edo Castle. But on the other hand, they had a dream to be promoted to higher classes.6. Specially, in the Tama District, there ware a lot of Ronin who came from the Kai District. They continued to practice Kenjyutsu as the followers of the Takeda Clan, despite the fact that the practice of Kenjyutsu had been prohibited in the village. They were thought to be Samurai who had practiced Kenjyutsu.7. And Hachioji-Sennin-Doshin wanted to be recognized as Samurai, so Shiono Tekisai set up his school with the Hachioji-Sennin-Doshin and became the chief mentor in many areas around Hachioji.
