Revolution helmets
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 the National Football League.〔Zaroa, Brett. 2008. "GRIDIRON GEAR GOES TO WAR." Popular Science 273, no. 3: 86.

This technology consists of a sensor in the helmet that relays data regarding the severity of each hit to a computer system.〔Noden, Merrell. 2004. "Charting All the Hits."

==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.〔Hoff, David J. 2006. "SPORTS SAFETY." Education Week 25, no. 24: 16.
