2,000 high school players participated in the study which took place over the course of three years. The research compared the Revolution helmet with other models. One major study on the helmet's effectiveness (funded by Riddell) was conducted by the University of Pittsburgh Medical Center. Injury Prevention Research and Controversy As of 2007, Riddell had sold 750,000 Revolution helmets. The Revolution was first distributed in 2002. While players and staff may be able to use this information in determining whether a player requires medical attention, there is currently no medically conclusive method of determining which impacts might lead to a concussion. A bar graph is used to indicate the force of the blow. When a player's head accelerates due to a collision, the acceleration is registered and brought up on a computer as a three-dimensional image of the head with the location of contact marked with an arrow. The Revolution helmet can be mounted with Head Impact Telemetry Systems (HITS) technology, a microprocessor, a radio transmitter, and a system of six accelerometers placed inside the helmet which measure the force, location, and direction of an impact on the helmet. A lightweight titanium face guard is attached to the helmet. The helmet is lined with a custom fit cellular air pad system made of polyurethane and synthetic rubber foam, and the shell is made of a polycarbonate alloy. Since most concussion-causing impacts occur on the side of the head and face, the helmet features mandible extensions which the cover the wearer's jaw line. An estimated 5 percent of high school players suffer concussions each year, and there is a widening body of evidence suggesting that long-term football players to a type of brain damage called chronic traumatic encephalopathy. Recent data has brought the issues of football concussions to the public attention. The helmet is designed around the head's center of gravity, and is intended to reduce the prevalence of concussions. The Speed Helmet is the most recent addition to the Revolution series of helmets made by Riddell. What research has been done on the helmet's efficacy so far has been inconclusive. The Revolution helmet was conceived in an attempt to reduce the risk of head injuries such as concussions. In head-on collisions, this panel gives by up to a quarter of an inch (6 mm), helping to absorb the impact. The Speedflex also features a built-in hinged panel located on the front near the top. This model can come equipped with Riddell's HITS Technology, which consists of a sensor in the helmet that relays data regarding the severity of each hit to a computer system. The most recent model in the Revolution line is the Speedflex helmet. The helmet brand is the most popular model in use in the National Football League, used by 83% of the players in the league as of 2008.
