IMPACT FORCES AND MATERIAL PROPERTIES OF A SOCCER HEADGEAR
AbstractThe Federation Internationale de Football Association (FIFA) has recently allowed players to wear headgear in international games. Previous research (Broglio et ai, 2003, Naunheim et ai, 2003) indicated that not all headgears were effective in attenuating impact. The purpose of this study was to determine the stiffness and shock absorbency of the material used in a Full 90 -True Play Technology soccer headgear. A second objective was to examine a measure of energy efficiency. The final objective was to develop an algorithm to predict the force of impact based on velocity.
