Abstract
A method and apparatus for testing a football helmet utilizes a weighted pendulum arm to impart an impact force upon the helmet. Linear head acceleration and rotational head acceleration caused by the impact force is measured and a Head Impact Power Index is computed and used as a standard to judge the ability and effectiveness of the football helmet in preventing injury to a football player.
