![]() ![]() When a player is hit, a five-point sensor (called a player unit) located in the helmet liner measures the impact. The technology is based on the HIT System and Sideline Response System. The InSite software measures HITsp, a head-impact metric encompassing how violently a player's head moves after contact, impact duration, and location. The project recommends players only wear helmets rated four- or five-stars.Ī rating for the SpeedFlex is not yet available, according to Duma, who spoke via email with SB Nation. In the most recent Virginia Tech helmet ratings, released in May 2013, Riddell had two helmets - the 360 and Revolution Speed - rated five stars, two helmets - the Revolution and Revolution IQ - rated four stars, and one helmet - the VSR4 - rated one star. So do these helmets work? That's still being determined. Helmet design may never prevent all concussions from occurring in football, but the evidence illustrates that it can reduce the incidence of this injury. Helmet designs should be optimized to reduce head acceleration over the continuum of impacts experienced by football players. This exemplar comparison illustrates that differences in the ability to reduce concussion risk exist between helmet models in collegiate football. In a study by Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences department head Stefan Duma and others, published on the Journal of Neurosurgery's website this past January, extensive research showed that helmet design does play a factor in player safety: The full rollout of SpeedFlex with InSite is expected to be complete by the 2015 season. InSite will be available for the SpeedFlex in limited quantities in time for the 2014 season.
