Riddell Revolution helmets are a line of football helmets designed to provide optimal protection for their users. The Revolution’s design has been proven to reduce the risk of sustaining head injuries during football games. These helmets are currently used by 83% of the players in theNational Football League.[1] The most recent model is the Revolution Speed helmet. This model can come equipped with Riddell's HITS Technology. This technology consists of a sensor in the helmet that relays data regarding the severity of each hit to a computer system.[2]

[edit]Injury prevention


Revolution helmets have been proven through studies to reduce the risk of head injury. One major study on the helmet’s effectiveness was conducted by a team from the University of Pittsburgh Medical Center. The research compared the Revolution helmet with other models. 2,000 high school players participated in the study which took place over the course of three years. Research showed that 5.4% of the athletes wearing the Revolution helmet suffered a concussion during a game as opposed to 7.6% of the players wearing the older model helmets. High school players wearing the Revolution helmet were 31% less likely to experience a concussion.[3]

The most recent addition to the Revolution series of helmets is the Revolution Speed helmet. This helmet improves upon older Revolution models to create a better defense against concussion.

[edit]Design


The helmet is designed around the head’s center of gravity. Since most concussion-causing impacts occur on the side of the head and face, the helmet features mandible extensions. This feature extends the cover of the jaw line. The helmet is lined with a custom fit cellular air pad system.Polyurethane and synthetic rubber foam are also used inside the helmet. The shell of the helmet is made up of a polycarbonate alloy. For the lightest weight, a titanium face guard is attached to the helmet.[4]

[edit]Revolution 360 Helmet


Riddell announced that a new model will be available in limited colors and sizes starting in Spring 2011. As of March 23, 2011, a firm date and price have not been announced. The Revolution 360 was first worn in a game by LaMichael James during the 2011 BCS National Championship Game, before the helmet was available to the public. At halftime, James switched back to his Revolution Speed.
