By observing three matches I felt comfortable that I was able to recognize a champion's full range of skill. At the level of World or Olympic quarter final competition I believe that each player is challenged to use only their best skills. Subjects of the research were Champions from all weight divisions. Unfortunately, I did not have sufficient records of any one Women's -72kg champion to be included in the final analysis. Numbers I was looking to see how many skills each Champion used.
Throws are very easy to count.
A player might use Seoinage, Tomoenage, Osotogari etc. Newaza, on the other hand presents a different situation. I chose to record newaza skills under the generic headings of Osaekomi, Shimewaza, Kansetsu and Sankaku. The range of throwing skills varied from just three throwing techniques, by super heavyweight World Champion Masaki, to nine different throws from middleweight Olympic Champion Yoshida. Use of newaza skills ranged from three types of newaza, used by Fairbrother, Kosorotv, Solodukin and Saito, to no newaza skills used by lightweight Olympic Champion Goussainov.
