THE DETERMINATION OF NOVEL IMPACT CONDITIONS FOR THE ASSESMENT OF LINEAR AND ANGULAR HEADFORM ACCELERATIONS
Keywords: Neurotrauma, impact, injury, angular acceleration, sports helmets
AbstractSports helmets, albeit very effective at preventing traumatic brain injury, have not mitigated the risk of mild traumatic brain injury in sport (Flik, Lyman, & Marx, 2005). Current protocols utilized in sports helmet testing incorporate only impact vectors through the center of mass, eliciting primarily linear accelerations. Angular acceleration has been suggested to be a better predictor of diffuse head injury than linear acceleration (Holbourn, 1943); therefore, the objective of this study was to develop a protocol capable of producing and measuring both forms of acceleration for future implementation into sports helmet standards.
