Not all football helmets are created equal.

Virginia Tech released results of its 2012 ratings for adult footbal helmets on Tuesday.

A total of three helmets received the five star rating for the ability to reduce the risk of concussion. They are the Riddell Revolution Speed  - the only one to receive the five stars last year.  Also with five stars are The Rawlings Quantum Plus and the Riddell 360.

Virginia Tech performs 120 impacts on each model.

Virginia Tech released today the results of its 2012 rating for adult football helmets that is designed to assess a helmet's ability to reduce the risk of concussion.

A total of three helmets achieved a "5 star" mark, which is the highest rating awarded by the Virginia Tech Helmet Ratings. In addition to the Riddell Revolution Speed, which was the only helmet to receive five stars last year, the Rawlings Quantum Plus and Riddell 360 also earned five stars as the best available helmets.

The process used for evaluating the head protector involves performing 120 impacts on each helmet model at multiple locations and impact energies. To date, the Virginia Tech Helmet Ratings™ for adult football include 15 helmet models that were evaluated using more than 2,000 laboratory tests. The ratings, first introduced in 2011, utilize the STAR Evaluation System to assess helmet performance.

The STAR, an acronym for the Summation of Tests for the Analysis of Risk, evaluation system was developed using data collected from over 1.8-million head impacts experienced by football players throughout an eight-year span.

"This is a perfect example of a National Institutes of Health (NIH)-funded project resulting in translational research. The NIH supported the development of the sensors and data collection that provided the foundation for our rating system. Specifically, you can see Riddell and Rawlings using this research to develop the very best helmets," said project director Stefan Duma,      the Harry C. Wyatt Professor of Engineering and department head of the Virginia Tech -- Wake Forest School of Biomedical Engineering and  Sciences.

A total of five new adult football helmet models by Rawlings, Riddell, and Xenith have been released since the Virginia Tech Helmet Rating were first made available in 2011. The Riddell 360 (5 stars), Rawlings Quantum Plus (5 stars), Rawlings Impulse (4 stars), and Rawlings Quantum (4 stars) were new models that are recommended by the researchers.

"We recommend any of the four or five star helmets for players. The specific helmet a player chooses will be dependent on other factors such as a fit and comfort," said Duma. The remaining new helmet model included in the 2012 ratings was the Xenith X2, which earned a three-star rating.


Seven helmets are now rated with four stars in the 2012 Virginia Tech Helmet Ratings: Schutt ION 4D, Schutt DNA Pro+, Rawlings Impulse, Xenith X1, Riddell Revolution, Rawlings Quantum, and Riddell Revolution IQ. The remaining five football helmet models were rated with three stars or less. The complete ratings are publicly available online by clicking here so that consumers can make educated decisions when purchasing football helmets.


"The three lowest-rated helmets from last year are now all off the market. It is encouraging to see this positive shift towards better head protection," said Steven Rowson, assistant professor of biomedical engineering at Virginia Tech. Rowson was responsible for the development of the STAR Evaluation System and testing of the helmets. "Four of the five new helmet models introduced in the last year earned a four- or five-star rating. This helps demonstrate that a data-driven approach can be utilized to optimize helmet design to reduce concussion risk," he said.


In the future, the researchers will expand the Virginia Tech Helmet Ratings to include other sports as well as youth football helmets. To this end, Duma and his team collected the first data set on head impacts experienced by youth football players last year. In the fall of 2012, researchers at Virginia Tech and Wake Forest will expand this data set by instrumenting over 300 youth football players from ages 6 to 18 in what is called the KIDS study (Kinematics of Impact Data Set).

"As we learn more about youth head impact exposure, we can begin to develop methods to evaluate youth-specific helmet designs," Duma added.

The Virginia Tech Helmet Ratings are independent of any helmet manufacturer and utilized funding from private donations, the School of Biomedical Engineering and Sciences, and the Institute for Critical Technology and Applied Science.
