University graduates of professional sumo wrestlers increased rapidly during the past decade, and it came to occupy 6% of the whole of the wrestlers, 36% of the ranking sumo wrestlers (sekitori). This is about 5 times 10 years ago. The success rate that becomes the ranking sumo wrestler of the university graduates is very high with about 60%. Professional sport is considered a kind of show business by Japan, and there is history that it has thought about with money-making impure job. Therefore, the sumo wrestler hasn't been considered the occupation which the person who graduated from the university so far. But, an amateur regulation was stopped from the participation qualification of the Olympic Games in 1974 and the boundary of amateur disappeared with the professional. In other words, amateur collapsed, and a professional became a center as for sport. And, games where the amateur wrestler who graduated from the university did sumo wrestling decreased. A university graduate wrestler has the privilege of "makushita-tukedashi" at the time as the first ring, 77% of them are using this privilege. Professional Sumo Association raises a standard for this privilege and a university graduate wrestler is trying so that it starts from the rookie, too. This privilege threatens a sumo stable as a structure of rookie training school.

Sumo (Japanese wrestling) is a sport culture that was fostered by Japanese people and Japanese culture, and it has a difinite organization and institution in the capacity of professional sports. The Sumodom (Sumo society) has many stables (Sumobeya) which are no parallel to other sports. Now, the Sumodom has about thirty stables. It is a unique institution in the world of sports. This Sumobeya is a private training center of Sumo where both a master (teacher) of Sumo and many diciples live together in a same house, in order to accede to the Sumo culture. And it has been extending over two handred years from the Edo period. This is to certify that Sumobeya is institutionalized in the Sumodom. The object of this research is to make clear the structure of Sumobeya in human relations. This research will find a clue to analyze the characteristic of the nation in Japanese sports culture. This research is a participant observation method in Takasago-beya. And the research materials (data) are my investigation in Takasago-beya which had extended for about two years from 1975 to 1977. The result of this research made clear that the structure of Sumobeya in human relations consisted of a fictional family institution. The family institution was just patriarchalism. A fictional family institution is a means of making up justification. The means are most simple and an effectual method for emotional, traditional and irrational personality. This personality is apt to accept to a fictional family institution.

The purpose of this study was to conduct a computer-assisted, comparative analysis of the Tokai University men's basketball team and 4 JBL Super League teams, and to find areas of improvement for the Tokai University men's basketball team and one particular shooter. Tokai University Basketball Game Analysis Software was specially developed to analyze characteristics of the offense of teams and of individual players. Three findings of the comparative analysis of the team were:(a) an increase in the shooting success rate through the strengthening of team offense, inside play, and offense rebounding; (b) an increase in the success rate of fast break; and (c) a decrease in turnovers. Also, two findings from the comparative analysis of a particular Tokai University player and a selected player from one of the Super League teams were (a) on-court judgments about the shot selections and (b) improvement in shooting ability. The author concluded that future practice of the Tokai University men's basketball team should be organized to improve these areas.

A number of handicaps found in children who were born between January and March can be seen as related to the age cut-off date for entering the Japanese educational system. However, because problems related to classroom studies are usually resolved in the middle years of elementary school, and problems related to physical exercise are usually resolred at the junior high school level, the question of the month of birth has not been considered a serious problem. These conclusions have come into question as it has been observed that the effects related to the month of birth tend to remain over a long period. The purpose of this study is to challenge the above assumptions and to study the relationship between the month of birth and a child's physical and mental development. The results of this survey are as follows : 1) At some national high school sports events, including baseball, football, and track and field, the number of participants born between January and March was very low. 2) Female students born between January and March are able to overcome physical shortcomings at a comparatively early age. 3) Athletes born between January and March are able to overcome physical shortcomings through exercise. 4) Children born between January and March generally score lower on high school and university entrance exams. 5) Children born between January and March tend to exhibit serious personality and behavioral problems. 6) Parents, teachers, school adminitrators and other leaders must fully realize the above facts. Such children need special care and confidence-building.

The purpose of this study was to investigate if a volleyball player could change the course of the spike by a signal given at various stage in spiking motion, and to find the differences of the spike form on these conditions. Conditions were to make a full swing spike toward a cross course and to change the spike course toward a straight course when signal was shown. All of spike motions were filmed and analyzed. Points of view for analyzing are following : a) Initial velocity of the ball. b) Maximum velocity of the finger. c) Body angle to the direction of running. d) Direction of spiking hand after striking the ball. Results of these experiments indicates that : 1) If the signal was switched on just before the beginning of the forward swing in spiking, all subjects could change the spike course on most occasions. On this study, "just before the beginning of the forward swing" meant about 0.30 to 0.35 seconds before the beginning of the forward swing. 2) Initial velocity of the ball, on the case when the signal was given just before the beginning of the forward swing, was later than ones on the another cases. 3) However, the finger velocity of this case was faster just before meeting to the ball. 4) There were no significant differences on the body angle to the direction of running jump at the various spike motions. 5) Directions of the arm after spiking the ball was decided depending on the course of the spike.

Boxing, though it is done through the medium of a pair of gloves, is a sport which fights to the extremity by fisting, and it remains, so to speak, the most primitive form. According to the boxing game, about 3000 B. C., on Aegean Crete island, the boxers rolled soft thongs in order to protect their fists. After that, by fitting out small iron tacks or boards, they were changed from the protection of boxers' fists to a murderous weapon and arm (in Greece from 400 B. C. to A. D. 390). In modern boxing, all the boxers roll bandages as the protiction of their fists and wrists. and at the same time, so as to soften the damage given their rivals, they wear a pair of gloves. Though rolling bandages purposes the protection of boxers' fists, there is sometimes a boxing leader who insists that how to roll them makes their punching force harder, and also there is a boxer who supports the opinion. In this study, we investigated the differences of punching force in a right straight blow and a left hook in the way of two kinds of rolling bandages. We used the punching measure which is developed by Ishiyama surgery at Surugadai Hospital of Nihon University and as testees, some members of our boxing club at he University of Tokai helped us. As the result of the investigation, we could not realize the difference of punching force from the way of rolling handages, that is, no significant difference. We can say, after all, punching force is much depended on the skills of their speed, timing, angle, power and so forth. Judging from the facts that they, in spite of rolling bandages, sometimes fracture their hand bones or sprain their wrists, as the original purpose of rolling bandages is the protection of the fist and wrist, we should devise how to roll bandages.
