The concept of lifelong learning is becoming a more conscious issue amongst the people of Japan. The basis of this concept is to change the school orientated education of the past which is deeply connected with the social changes of today. Also bearing in mind these social changes, it is important that judo develops ideas and adapts to this new view point of lifelong learning. This thesis first compares the theory of judo and lifelong learning. Second analyses the actual state of judo today, and finally considers the way of judo in this period of lifelong learning, looking at it from a social education view point. The following points give both an explanation and proposal based on the results of this thesis: 1) Regarding theory, judo and lifelong learning show many common features. Judo is suitable in developing lifelong learning. 2) Judo in Japan, today is concentrated amongst schools and the younger generation. It is necessary to changs this environment via lifelong learning. 3) In the field of social education, groups that develop unique activities are active as a result of the flexibility of their ideas. A characteristic of jido is its variety of ideas, therefore, it can be said that judo is suitable for lifelong leaning. As a conclusion, a system of “various activities of judo based on lifelong learning” is depicted in the following plan. Finally, it is neccessary to strengthen the connection of each area and activity, and as a result reorganisation of such activities in a practical fashion is the next step.
This study was planned to compare the Bone mass of KENDO aged men with that of normal aged controls to make clear the effects on the long term practice of KENDO. The subjects were 21 KENDO aged men (KENDO aged group),19 normal similar aged men (Control group), and 8 KENDO young men (KENDO young group). They had average ages of 68.9 years,66.9 years, and 30.4 years. Measurements were made using an Achilles Ultrasound Bone Densitometer (Lunar corp.Madison WI). We measured velocity (SOS; speed of sound), attenuation slope (BUA; broadhand ultrasound attenuation), Stiffness (calculated from the combined data of SOS and BUA), and Osteoporotic centile in the os calcis. Mean values of SOS, BUA, and Stiffness in KENDO aged group was significantly (p<0.001) higher than in control group.Osteoporotic centile in KENDO aged group was significantly (p <0.001) lower than in control group.And, the difference between right and left had no signifficant in both group.These results suggest that regular long term KENDO practice is effective for the maintenance of bone mass
For the purpose of exploring desirable opponent perception in Kendo, we investigated how Kendo athletes sized up their opponent and planed a coming game with the opponent in watching the opponents'past games. The subjects were 11 female college Kendo athletes,6 athletes with high performance level and 5 athletes with medium performance level. Ten female college Kendo athletes who had a different Kendo style to each other and belonged to a different college from the subjects were selected as opponents for this study. After watching the video-taped game of each opponent, the subjects rated the opponent on 19 bipolar scales, described their game plan against her and answered the reason why they chose the plan, whether they are good at performing the plan, and whether they change the plan or not in the case of that the plan does not work out in the game. The major findings were as follows.1) After watching the opponent's game, the subjects recognized the opponents on the basis of their “competence”, “offensive attitude”, “WAZA style”, and “regularity. ”Compared with the result of our precedent study on the cognitive structure before watching an opponent's game, the cognitive structure after watching an opponent's game was more distinctive and attending more to the opponent's WAZA.2) In most of the cases, the subjects had more than one plan and got ready for partly or totally changing the plans which might not work out in the actual game.3) Both the high and the medium performance level athletes made their game plans with referring to the opponent's distinctive movement and WAZA style rather than with adhering to their own WAZA which they were good at. However,4) compared with the medium performance level athletes, the high performance level athletes made more plans and were more likely to be good at performing the plans they made. These findings suggested that watching an opponent's game before competition would be beneficial for sizing up the opponent and making game plans. However, whether the preparation actually works out in competition seemed to depend on the variety of athletes' techniques and on the variety of the ways in which they can use their techniques to advantege.
In ancient Japan, the concept of gods had been changed as passing of time. From this fact, it is expected that Japanese primitive faith had been changed, as sword culture was transmitted from China. In this paper, we describe transformation of primitive belief and foundation of unique Japanese sword culture, in the process of accepting sword culture. The summary is as follows: 1. Sword culture influenced ancient Japanese mental world, and changed belief in the fire. This belief in the fire changed from destructive to constructive and part of this had been absorbed in the concept of sword. 2. Originally, ancient people believed in god of snake that supported farming. But, as the time went by, power of god of snake had declined, and this faith was absorbed in the concept of the sword. 3. Power of god of thunder had decline, too. The belief in this had concentrated at peculiar god “Takemikazuchi”, and this had been related to sword. 4. The sword came to absorb concepts of fire and snake. And related to “Takemikazuchi”, it was recognized as god itself. 5. From the above discussion, it is assumed that there is a unique Japanese way of thinking that sword is related to god. This is thought to be a foundation of concept of sword in Japan.
The purpose of this study was to compare the balancing ability against abrupt acceleration of elderly males with practicing Judo (Judoists) with that of elderly male walkers (Walkers). In addition, a comparison proprioceptive sense and motor function of Judoists with Walkers were examined. Six Judoists (a mean age of 70.7+2.1 year, mean experience of Judo of 56.2 ± 3.1 years) and seven Walkers (a mean age of 69.3±2.5 years) were volunteered for this study. Changes in the center of foot pressure (CFP)during postural sway against abrupt acceleration were measured for all subjects. Response time and CFP displacement were evaluated for the CFP data. Their sensory and motor function tests (knee proprioceptive sence, muscle strength, flexibility, reaction time, static balance) were also administered. The following results were obtained. 1. The responce time and CFP displacement were significantly (p <.05) smaller in the Judoists compared to the Walkers. 2. The Judoists exhibited significantly (p<.05) smaller errors in passive knee proprioceptive sense than did the Walkers. 3. The Judoists exhibited significantly (p<.05) greater strength and flexibility of the ankle and hip, and decreased choice reaction time. These result suggest that the postural balancing ability in the elderly males with practicing Judo was sufficient compared to the elderly males with walking, which was due to the influence of increased proprioceptive function, muscular strength and flexibility of the legs and hips, and decreased choice reaction time in the Judoists.
