The questionnaires were distributed during the begining of Oct. to the middle of Dec.1984. The responses were obtained toward the case of higher level, same level and lower level opponents.
The subiects were 173 Karate players belong to the club in high school, college or company. They were divided in three groups. In the first group, the players had over 2nd dan degree (E group, n=43), in the second group, the players had 1st dan degree (G group, n=53) and in the third group, the players had under 4th kyu degree (P group, n=77).
The results were summarized as follows
1. Especially, the players in P group were more overwhelmed by higher level opponents than the other levels.
2. In the kumite with higher level opponents, players in all groups were overpowered with opponent's skill factor, followed by the mental and physical factors. And players in P group were affected by the mental factor as much as skill factor.
3. Regarding to the players who were overpowered with mental factor, there were no relation to opponent's skill levels in E and G group, but in P group there were many players who had much more pressure in kiumite with higher level opponents than the other levels.
4. Regarding to the players who were overpowered with opponent's skill factor, many of them, disregard to their groups, had much more pressure in kumite with higher level opponents than the other level.
5. To be overpowered with opponent's physical factor was no relation to self and opponent's skill levels.

The purpose of this study was to investigate the characteristics of displayed force by left fingers on the handle of“shina-i” (fencing stave used in “kendo” ) in kendo (Japanese fencing) while hitting an opponent's face guard or hand armor from the position of the “shina-i” held above the head with left hand and supported ligthly with right hand. The present authors recorded the changes in left elbow joint angle, each force of left index, middle, ring and little fingers exerted on the handle of “shina-i” in three male adult who were skillful at hitting especially from the position of the “shina-i” held above the head. The following results were obtained.
1. Observing from the changes in left elbow joint angle, the subject hit the opponent's faceguard or hand armor, fully extending his left elbow joint. Each goniogram obtained in ten trials showed almost the same pattern in each technique (“men” or “kote”).
2. Left little and ring fingers showed peak force at the point of time of 0.11-0.12 seconds prior to the moment of hitting the opponents, accompanying speedy extension of its elbow joint, in each technique in all subjects. On the contrary to this, the index finger's force began to increase from the moment when the little and ring fingers showed peak force, and it showed peak value just about at the moment of hitting the opponent. The middle finger's force increased at the same time or just after the display of force in little and ring fingers. This first peak value was followed by the second peak one. Therefore, the pattern of displayed force in middle finger showed the intermediate aspect between those of little, ring and index fingers'.
3. When each peak force value was expressed as a percentage of maximum strength of each finger, the little and ring fingers' showed 139-202%and 100-120%, respectively, in technique of “men.” In technique of “kote,”the little and ring fingers' showed 181-240% and 95-105%, respectively.

We constructed the new data base management system for personal computer, MULTI 16, by the MBASIC. This system managed the data base and/or data file consisted of the results of Judo games and its adress of video tapes. Up to now the volume of this data base was 473 records. This system has 3 functions, (I) Input (II) Retrieval (III) Correction and/or revision. Strong point for this system was more userfriendly.
