Background The present study examined the effects of the seoi-nage skill using expert (i.e., elite) and novice (i.e., non-elite) judo athletes. Methods Ten with expert judo athletes and 10 novice judo athletes were instructed to perform seoi-nage skill that consist of three phases (i.e., unbalancing, positioning, and throwing). Kinematic characteristics of the three phases data was collected from an optical motion capture 3D camera, and used to measure the magnitude and direction of the force. Results The results indicated that the expert judo athletes showed better performance the rotation and tilt angle characteristics of the shoulder and pelvis, and hip and knee joint flexion-extension angle during seoi-nage skill compared with novice judo athletes. In addition, the shoulder and pelvis of expert judo athletes exhibited together while maintaining the extension of the hip and knee joints to achieve effective sedation than novice judo athletes. Conclusions These results suggest that the force and movement control is important for the implementation of optimal the seoi-nage skill. |
