The purpose of this study was to clarify the unique kendo moves used by the All Japan Kendo Champion Masahiro Miyazaki, six-time winner of the all Japan Kendo Championship.Using a direct linear transformation method, traces of the locomotion movement of the kendo players were measured. These measures permitted analysis of the spatial distances between the two competitors (i. e., ma-ai) during their matches. Distribution curves revealed two main types of ma-ai, one which had a higher peak position of sword-guard tangle (i. e., tuba-zeriai), and the other (i. e., issoku-itto-no-maai), which is the distance which enables players to either strike the opponent by taking one step forward and to evade the opponent's striking one step backward. Longitudinal data of 47 matches over 10 years (1990-1999) revealed that: 1) The percentage occurrence of Miyazaki's issoku-itto-no-maai was lower relative to tsuba-zeriai, which is typical of all such players. 2) The number of Miyazaki's offensive and defensive movements from issoku-itto-no-maai was higher than that of all such players. 3) The total times of confrontation in Miyazaki's issoku-itto-no-maai were significantly lower than that of all other players. Namely, his initial offensive movement is much earlier than that of all other players. 4) Miyazaki's percentage occurrence of issoku-itto-no-maai tended to increase year by year, coupled with a decrease in the number of offensive and defensive movement from ma-ai.
“BUGEI-ZUFU-TSUUSHI” is a set of books about martial arts in Korea and consists of 6 vols. It was published in 1790. In vol.1 to vol.4 of the books, some comments on technics of 24 different types of martial arts in Korea were written. Vol.5 is “THE KOREAN VERSION”. Vol.6 is “THE ILLUSTRATED VERSION”. The contents of “THE KOREAN VERSION” are written by chinese charactors and korean charactors and the contents of “THE ILLUSTRATED VERSION” are flowcharts about technics of martial arts. In this study, I investigated the background about formation of “THE KOREAN VERSION” and “THE ILLUSTRATED VERSION”. The results can be summarized as follows. 1. “THE KOREAN VERSION” and “THE ILLUSTRATED VERSION” were digest of vol.1 to vol.4 of “BUGEI-ZUFU-TSUUSHI”. 2. “THE ILLUSTRATED VERSION” compensates for lack of illustration in “THE KOREAN VERSION” 3. A pragmatic line of thought that became influential in the latter 18 century in Korea affected the formation of “THE KOREAN VERSION” and “THE ILLUSTRATED VERSION”. 4. PAK-CHE-GA (1750-1815?) is a thinker in RICHO Era on Korea. His opinion in his writting “HEIRON” (This is a part of book that his work “HOKUGAKUGI”) affected the formation of “THE KOREAN VERSION” and “THE ILLUSTRATED VERSION”
