Twist downs are competitive versions of Uki Otoshi and Sumi Otoshi. Kouchigari and Twist Downs were observed in all Championships reviewed from 1983 to 1995 as well as the 1992 Olympic Judo competition. Pick-ups, competitive versions of Teguruma, Kuchiki Taoshi, Morote Gari etc., etc., showed wide spread use. However, Pick-ups appear to be a recent development in competitive Judo. The recent appearance of Pick-ups could indicate a fad or a developing trend.
Further analysis is required to draw any conclusion.
Not surprisingly, Uchimata and Seoinage are the most frequently used major skills. Distribution of newaza skills was surprising on two points. First, I was surprised to realize that the elite players would forego the opportunity to use one newaza skill in favor of something else. Players seek their favorite throws in spite of the opportunity for another throwing skill on a regular basis. Obviously, each individual must stick with the skills that he feels most comfortable with.
