【 摘 要 】

The aim of this study is to make an experimental determination of restitution coefficient during the clash between ball and stick in oina game. This study is made using a complex system for movement analysis named VICON, on 17 oina balls, that have different wear stages, in contact with two different sticks that have different texture. We make the measurement of cinematic parameters of specific points that are marked, on the equipment, during movement. These parameters are used for calculate, using 2 methods, the restitutions coefficients. The values of these coefficient are 0.44-0.545. This analysis allows to make a prediction of balls trajectory, based on movement measurement during clash and also help to optimization of motor performance in oina game.
