The purpose of the present study was to examine methods of feints in judo throwing techniques by being based on movement structures. The participants were 11 national intercollegiate judo players and they gave demonstrations of their own favorite throwing techniques with the feints. A seventh-dan grade judo expert and 10 participants except for a demonstrator evaluated whether 32 demonstrations contained feints or not. By their agreement on each evaluation, 18 kinds of the throwing techniques with the feints were selected for the analysis. The impressionistic analysis by means of other-observation was conducted about the phase structures of the movement process in the throwing techniques with the feints. The results demonstrated that the methods of the feints were divided into two motions, which were Tsukuri and Kake of a certain throwing technique, and that the combination methods of the feints and the throwing techniques were divided into two sorts, which were the connections to either Tsukuri or Kake of the throwing techniques. Sannohe (1999) advanced a theory that judo throwing techniques could be classified into two types : rotation and non-rotation. Binomial tests indicated that when the type of the feints was rotation and the type of the throwing techniques was non-rotation, there was a significant difference between two combination methods : 0 connections to Tsukuri and 7 connections to Kake, and that when the type of the feints was non-rotation and the type of the throwing techniques was rotation, there was a significant difference between two combination methods : 8 connections to Tsukuri and 0 connections to Kake. Results are discussed with relation to practice and instruction in feints in judo throwing techniques.
