Ukemi movements against migi-tsurikomigoshi were analyzed by 16 mm kinematography and acceleration transducer in order to obtain some informations usefull in effective instruction of Ukemi in Judo.Movements of Ukemi were considered all complete with in approximately 0.3 sec. There found `pronounced discrepancies between the recorded values and the values claimed by the subjects in their feeling as to the time of completion, sequence of the body parts hitting the mat, and the angle formed between the. arm and the side of the trunk.Subject T. T. whose performance in Ukemi was rated excellent, registered a double hitting on the mat with his left arm which reduced the landing shock to the neck markedly. The highest angular velocity of his neck was 530°J sec.Subject Y. S. whose Ukemi performance was rated very poor, showed pushing movement against the mat rather than the hitting movement in his left arm. The landing shock to his neck was great, as recorded in the angular velocity of his neck which reached 1260°/sec.It was concluded that: (1) avoidance of the confusion between the mechanical phenomena actually took place and the subjective feeling of the performance is necessary; (2) function of absorbing the impact with viscosity and elasticity must be considered; in order to improve the effectiveness of instruction in Ukemi.
