Abstract

The purpose of the present study was to compare the biomechanics parameters of seoi-nage between a skilled group and an unskilled group. The motion data of the seoi-nage were collected on three male elite judo athletes and sixteen male student judo athletes using a three-dimensional motion analysis technique and groups based on skill level were compared. This study found that the anterior-posterior component of the centre of mass velocity of the tori and average anterior-posterior component of the hip velocity of the swing leg in the knee extension phase were significantly larger in the skilled group than those in the unskilled group. The information suggests that it may be more important for judo athletes to maintain the linear velocity towards an opponent than body position of the tori relative to the uke for better seoi-nage performance.
