Abstract

The purpose of this study was to develop a judo-doll uke (partner) for training and measurement applicable to pulling, pushing and sweeping in Judo. In Judo the most common techniques consist of the pulling, pushing and reaping which all need to be practiced with a partner. So research needs to develop a measurement system that can be used to evaluate the forces involved with these techniques. The Doll-Uke was developed so that Judoists can train alone. After the manufacture of Doll-Uke the strengths and weaknesses were recorded and evaluated. The height of a Doll-Uke is 170cm and has a weight of 70kg. Doll-Uke was developed with a trunk angle of 55° and the lower extremities of an angle of 45°. The Doll-Uke can also measure the forces developed during the pulling, pushing and reaping. Due to the ability of the system to measure the forces while performing Judo techniques, feedback can be provided to the Judoists to improve their performance during training.
