For the purpose of determining the technical characteristics of the Kendo strike with the Jodan-no-Kamae in Kendo, we measured the impact force of the one-hand Shomen-and Kote-uchi using as subjects five college Kendo club students. And analyzed the data by a motion analysis system with a video tape recorder. We also measured the impact force of the two-hand Chudan-no-Kamae strike for comparison. The following are the results obtained from a biomechanical examination of the data.1. The downward maximum magnitude of the impact force of the one-hand Kote-Uchi (150.03 ± 21.35kgf) was greater than that of the one-hand Shomen-Uchi (120.99 ± 11.55kgf). This difference was a characteristic of the one-hand strike but not of the two-hand strike.2. The angular motion at the left shoulder, from which the Shinai is brought down, was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi. This will explain why the vertical component force of the one-hand Kote-Uchi was greater than that of the one-hand Men-Uchi.3. With respect to the vertical movement of the Kensen, the maximum speed was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi while the opposite was the case with respect to the forward movement. This was in accord with the observation that the maximum magnitude of the impact force was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi with respect to the vertical movement whereas the opposite was the case with respect to the forward movement.4. The correlation coefficient between the impact time and the maximum magnitude of the impact force was small whereas the correlation coefficient between the impact time and the impulse value was great.5. There was not an appreciable difference in the magnitude of the impact force between the one-hand and two-hand Men-Uchi. However, with respect to the right Kote-Uchi, the maximum magnitude of the impact force was greater in every direction for the one-hand strike than for the two-hand strike. Most notably, with respect to the downward movement, the maximum magnitude of the impact force of the one-hand Kote-Uchi was greater than that of the two-hand Men-Uchi.

For the purpose of determining the technical characteristics of the striking motion from Nito-no-Kamae in Kendo, we measured the impact force of the striking motion with DAITO (long-shinai) and SHOTO (short-shinai) using as subjects three male university teachers, who are majoring in Kendo, and analyzed the data by a motion analysis system with a video tape recorder.For comparison, similar measurements were performed on the striking motion with the two-handed striking motion from Chudan-no-Kamae and the one-handed striking motion from Jodan-no-Kamae.The following results were obtained from a examination of the data.1. The maximum downward magnitude of the impact force and the downward impulse value of three kinds of the striking motions with SHOTO from Nito-no-Kamae were greater than that of the two-handed Shomen striking motion from Chudan-no-Kamae. However, the maximum downward magnitude of the impact force and the downward impulse value of two-kinds of striking motion with DAITO from Nito-no-Kamae were smaller than that of two-handed Shomen striking motion from Chudan-no-Kamae.2. The impact time of all the striking motion from Nito-no-Kamae were shorter than that of the two-handed striking motion from Chudan-no-Kamae.3. The motion of shinai in the striking motions from Nito-no-Kamae were chiefly made using the left elbow and the left wrist.4. The angular velocity of shinai immediately before impact using Hikikote striking motion with SHOTO of Nito-no-Kamae was the largest, and that using the Shomen striking motion with DAITO of Nito-no-Kamae was the smallest.

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.

本研究は,剣道において面や突きなどを打突された際に,剣道具(面)をとおして人体の頭部に伝達される衝撃力について,バイオメカニクス的観点から明らかにするために,打撃用ダミー人形や被験者への実戦的な打突が頭部へ及ぼす力学量(加速度)を計測し,頭部の安全性についてJARIの人体頭部耐性曲線を元に検討することを目的とした。得られた結果をまとめると以下の通りである。1.一足一刀の間合からの面打撃は,加速度レベルが低いため,加速度による傷害発生の可能性が3種類(MA:その場から,MB:送り足で,MC:一足一刀の間合から)の打ち込み条件の中では最も低かった。2.頭部への一回の打撃により頭蓋骨々折・脳震盪といった傷害が生じるレベルには達していない。しかし,慢性硬膜下血腫の発症との関連も心配されることから,連続的な衝撃や長年にわたる衝撃の影響について,今後検討する必要があると考える。3.突き動作では加速度レベルが低いため,加速度による頭部の傷害発生の可能性は低いと考えられる。

本研究は、平成17年度から平成19年度にわたって、剣道難聴予防のための基礎的研究として『剣道難聴を予防するための剣道具(面)の開発研究』を行なった。研究の概要は、平成17年度には、剣道を専門的に実践している学生や警察官を対象として「剣道難聴」の実態調査を行い、高い出現率と2kHz,3kHzそして8kHzが存在することを明らかにした。その原因と考えられる「剣道騒音」について分析(音圧・周波数)を行ったところ、掛け声、踏み込み音、竹刀音、打撃音などに固有の周波数あることや、かなり高い音圧の騒音が発生していることが明らかになった。平成18年度には、剣道騒音と剣道難聴の関連性について検討したが、測定器具の精度や生理的な個人内変動などの問題が生じたため、その因果関係については明らかにならなかった。平成19年度には、現実的な対応として難聴予防のために遮音性の高い「面」布団の芯材やその構造などの改良を行うために、各種面の遮音性についての検討を行なったところ、各種面布団の遮音性は1kHzでは低いと考えられるが2kHz,4kHzと周波数が高くなるにしたがって高くなり、ミシン刺しより手刺し材料の方が遮音効果は高く、化学素材(ソルボセイン)を1枚加えると、あらゆる布団材料よりも遮音効果は高くなるなど、剣道具開発のための有益な礎的資料を得ることができた。

The purpose of this study is to reveal the degree of individual motional difference and to discover the situations and parts of the body where there appears motional difference and to gain basic hints in instructing Shomen-Striking-Motion, as well as to discover implicit motional process common in Shomen-Striking-Motion of a Kendo player and to establish a model of standard Shomen-Striking-Motion by analyzing Kendo Shomen-Striking-Motion using 3-D Motion Analysis Method.The subjects of the study were sixteen males (age: 24.6±5.8years old, Kendo experience: 16.2±5.2years, ranks in Kendo: 4.0±1.3 dan, height: 174.9±6.0 cm, weight: 76.0±8.0 kg) consisting of the current students and the graduates of a university where is a specialized Kendo course.Videotaping of Shomen-Striking-Motion of the subjects was done by using two high-speed VTRs from diagonally to the right-front and left-front of the subjects with shooting speed of 250 frames per second and the shutter speed of 1/2000 second.3-D coordinates in 29 points were calculated in total with the use of DLT (Direct Linear Transformation) Method, consisting of 25 segment endpoints of a subject and 4 measuring points of Shinai.The Shomen-Striking-Motion were divided into two phases in this study; Back-Swing phase (BS phase) which is from the starting time until the ending time of Shinai to be lifted up and Forward Swing phase (FS phase) which is from the starting time until the ending time of Shinai to be struck down. Then,3-D coordinates and angle data of each subject were standardized with phase time being 100%, and the data were averaged per 1% of standard time accordig to the method of Ae et al. Coefficients of variation were calculated to compare standard deviation of each joint angle that was averaged.The following are the acquired conclusions from this study.(1) 3-D model of the standard Shomen-Striking-Motion was acquired that shows implicit motional process common in Kendo players through standardizing and averaging all the coordinate data of sixteen subjects.(2) The standard motion of each joint of Kendo players in fifteen points was exhibited through standardizing and averaging the changes of joint angle of all the subjects. Simultaneously situations that have large and small individual motional difference were observed from the standard deviation.(3) The parts were revealed where there is large individual motional difference by calculating coefficients of variation in the standard deviation of joint angles.

The purpose of this study is to investigate the influence of the left foot outward angle in Chudan-no-kamae on the Shomen-uchi.A force platform was used together with 16 mm cine camera to investigate synchronously the mechanics of take-off motion during the Shornen-uchi in Kendo.The records of the force components of foot pressure on the floor of the male Kendo players were obtained at the take-off motion during Shomen-uchi. Subsequently, the records were taken with the body movements shown in 16 mm film.The subjects for this study were 9 male students of the Tsukuba University,20 to 23 years of age,12 to 15 years of experience and 3 to 4 dan degree.The results obtained are as follows:1. The leftward and the backward components of foot force increase with the change of the left foot angle (from 0° to 50°). The tendency above mentioned is clearly observed over 30° and especially at 50°.2. The larger the left foot angle at Chudan-no-kamae is, the more the maximum magnitude of leftward force (Fx) increases. On the contrary, both of the backward (Fy) and vertical (Fz) forces during take-off motion at Shomen-uchi decrease.3. A larger and sharper peak in the force curve of the backward and vertical components is observed at the angle under 20° and especially usual foot position.4. The angle of forward inclination of body (∠f) decreases gradually with the increase of the left foot angle. The angle of trunk (∠a) decreases as the result of an inadequate left foot action, which causes delay of the posture recovering after striking motion.

Fuminori NAKIRI(Tokyo University of Agriculture and Technology)The purpose of this study was to analyze the shoulder and waist in torsion on the Shomen-uchi movement in Kendo at two types of distance. The shomen-uchi movement was filmed at 100 f. p.s with two 16mm high speed cameras. Three-dimensional coordinates for the segment endpoints were computed by using a direct linear transformation technique. The subjects for this study were 5 males,19 to 20 years of age, with 7 to 10 years of experience and 3 dan degree.The results were summarized as follows: 1) On the long distance, the changes in the shoulder and waist angles seem to be larger, and the amplitude in the shoulder and waist angle in torsion also seem to be larger.2) There were two types of movements in the shoulder and waist angle in torsion on the shomen-uchi movement.A type: In the phase of the maximum point of raising the shinai, there was a cross motion between the shoulder and the waist.B type: During the shomen-uchi movement, no cross motion occurred between the shoulder and the waist.

The purpose of this study is to clarify the morphological features and characteristics of the standing posture of the Kendomen in comparison with the Judomen and non-athletes.We studied on the changes of the relief of the back during various standing posture with the aid of moire contourography. And also, we studied on the vertebral column by the conformateur and the perpendicular line of the body gravity center by the gravianalyzer.The subjects for this study were thirty four Kendomen, twenty six Judomen and twelve non-athletes, students of Tsukuba University, aged 18-20 years.The results were as follows:1) In the girth of the upper limb and the forearm of the Kendomen, a striking contrast between right and left was observed.2) The right shoulder of the back of the Kendomen had a tendency to be in the front and downward.3) The moire contourography of the back of the Kendomen, Uudomen and non-athletes were taken and the characteristics of the relief of their back were examined.4) Of the vertebral angles of the Kendomen,. the angle A (inclination of cervical lumbar line) in the relaxed posture took a negative value, and this tendency was more conspicuous in good and military posture.5) In the position of the body gravity center,. little difference was found between the Kendomen and the non-athletes.6) A few students both in the Kendomen and non-anthletes had the perpendicular line of the body gravity center laid upon the aulicular line. In the good or military posture, the incidence of the overlie of two lines became more frequent.

平成11年度研究課題:剣道具(突き垂・顎垂)の形状および構造の安全規格値作成のための基礎的実験研究1.目的:前年度の突きの衝撃力の測定実験結果を踏まえて、面部の突き垂および顎垂の材質や形状さらには相互の位置関係などによる緩衝性能の相違を明らかにし、より安全性の高い剣道具の開発を行うと同時に安全性の観点からの規格値を作成する基礎的資料を収集したものである。2.方法:自製の突き力測定装置(キスラー社製3分力ロードワツシャー形式9067を使用)を使用し、突き力発生試験機を改良し、前年度成果より成人剣道選手の平均的水平分力(150kgf)と同じ条件で突き力を発生させ、一般的に普及されている合計9種類の面材料を対象とし、その材料や突き垂と顎垂の間隔、突き垂形状、突き垂の突く位置などの相違による緩衝性能について実験的に検討を行った。3.結果:(1)突き垂と喉までの間隔が突きの緩衝性能を高めていることが明らかになった。(2)突き垂の部位の突く位置により緩衝性能は異なり、中央より下部での緩衝性能はかなり劣ることが明らかとなった。(3)突き垂の厚みと硬さが突きの緩衝性を高めていることが明らかとなった。但し、突き垂の表面形状が丸みを帯びている場合には、滑って顎垂もしくは喉元に力が直接的に作用することが明らかとなった。(4)突き垂・顎垂の形状及び芯材の種類やその構成、さらには突き垂と顎垂れの位置関係が緩衝性能に及ぼす影響については今後詳細な検討を行う必要がある。
