Comparison of center of mass and chest based inertial sensors in the soccer throw-in

Abstract

Soccer is one of the most popular team sports played in the world. The throw-in is a method to restart play after the ball has left the playing area and occurs many times in a game. The biomechanics of the soccer throw-in have been well studied and it has been established that the rotation of the torso contributes to the distance of the throw-in. Our previous work has involved attaching inertial sensors to the soccer player whilst performing the soccer throw. This paper aims to compare the Centre Of Mass inertial data with the Chest based inertial data so that a useful placement of the inertial sensors can be found.
