Abstract

The purpose of this study was to investigate head motion of children of varying levels of motor ability performing an overarm throw towards a forward facing target. Ten ten-yearold children were analysed using three-dimensional veideographic techniques. Angular motion of the head about its three axes was determined with respect to the external reference frame and with respect to the trunk. It was found that all subjects stabilised their heads during the performance of the throw. The angular velocity of the head immediately prior to release small despite large trunk angular velocity.
