abstract

In the long term, quantitative measurements indicating the magnitude and nature of head impacts will be essential to understanding the biomechanics of head injury. Tools are needed that can quantitatively measure the levels of head acceleration experienced by athletes in a variety of situations in order to assess these risks. The current research is aimed at developing instrumentation that is comfortable enough to use in the field and which can measure head accelerations from blows to the head repeatably and accurately. Soccer is a unique sport in that the unprotected head is deliberately used to direct the motion of the ball during play, which makes it practical to study in a controlled laboratory setting. While the possible long-term effects of heading are still subject to debate [1,2], there is evidence which suggests that it is responsible for transient neurocognitive deficits [3] and transient concussion symptoms [4].
