The purpose of this study is to obtain the useful data for the improvement of combativity on different levels of judo competitions.
The results are as follows:
(1) The average dan grade of participants is higher in higher level of judo competitions. Participants in All-Japan level are taller, heavier, and younger than those in Tohoku-Area level on the physical characteristics and the chronological age.
(2) The percentage of participants with left-side gripping is higher in higher level of competitions such as All Japan Judo Championship and Kodokan Cup All Japan Judo Championships. Competitors with left-side gripping showed higher percentage of victory in the matches of right versus left-side gripping.
(3) There is no remarkable differences of techniques applied on the different levels of competitions.
(4) The average frequency of techniques applied per minute is higher in higher level of competitions. Competitors who applied more various techniques showed a higher percentage of victory.
(5) The number of variety of techniques applied per minute is higher in higher level of competitions.
(6) Participants in higher level of competitions apply techniques concentrically and frequently in the latter half of the match.
From the above, it seems to be indispensable for the competitors to develop the endurance which enables them to apply various techniques concentrically and frequently in the latter half of the match as well as to apply various highly-skilled techniques constantly throughout the match.
