NOCSAE’s Statement On Virginia Tech Helmet STAR Rating System

June 7, 2012 /

The National Operating Committee on Standards for Athletic Equipment (NOCSAE) advocates ongoing research on athletic safety in order to gain a deeper understanding of protecting athletes from concussions. However, NOCSAE does not recommend that parents and athletes form decisions on the safest and most effective equipment based on any single individual data point, rating, or measurement, including the Virginia Tech STAR football helmet rating system. Doing so may lead to inaccurate conclusions that one helmet brand or model has a measurably higher level of concussion protection than another for a particular athlete.

“As stated in the STAR FAQ on the Virginia Tech website, the STAR rating system is ’a theoretical calculation that is based on a probabilistic analysis of impact exposure and injury risk.’ This theoretical calculation relies on a single head acceleration criteria to predict the probability of a concussion, which is a complex event involving different and changing forces, linear and rotational accelerations, impact duration, player concussion history, overall health, helmet fit, and potentially even genetics.

“Additionally, and perhaps of most importance, is that this ranking system, to the extent it may be predictive, is limited to only starting collegiate players wearing an adult large helmet. To quote again the Virginia Tech website ’it is not safe to extrapolate the findings to youth football helmets. The STAR evaluation system was developed based on the head impact exposure of collegiate football players.’

“There is no indication from the STAR system or published methodology that a large size in one model will test the same as a medium or small or youth size in the same model, and to assume that the STAR value will apply across the board for all sizes of the same model is not safe, and potentially harmful.

“NOCSAE urges parents and athletes to gather all the facts about football helmets and concussion protection from a variety of reliable sources. Athlete safety is too important to rely on only one partial measurement of helmet performance.
