Protecting Your Child’s Head: New Football Helmet Study
(Ivanhoe Newswire) — Youth football helmets are currently designed the same as adult helmets, even though it isn´t known how child football players impact their heads. This novel study conducted at Virginia Tech investigates the head impact characteristics in youth football, and will greatly enhance the development of improved helmets specifically designed for children.
The Auburn Eagles, a Montgomery County, Virginia youth team consisting of 6 to 8 year old boys, has participated in the study since August. The helmets of the child football players are instrumented with custom 12 accelerometer arrays that measure how a child's head responds to impact. Each time a player impacts his head, data is recorded and wirelessly downloaded to a computer on the sideline.Previous Virginia Tech research on the school´s own football team has led to the development of the National Impact Database, which contains the first safety rating system ever available for adult football helmets (STAR Evaluation System). Similar developments for youth football are anticipated from the current study with the Auburn Eagles.
"Based on eight years of studying head impacts experienced by Virginia Tech football players, we were able to quantify exposure for adult football players relative to impact location, severity, and frequency," Stefan Duma, the Virginia Tech professor of biomedical engineering and department head of the Virginia Tech — Wake Forest University School of Biomedical Engineering and Sciences (SBES) that directs this project, was quoted as saying. "Unfortunately, we cannot translate the adult exposure to the youth helmets because the impact conditions of youth football are completely unknown. To solve this problem, we are applying the same approach that we have used with the Virginia Tech football team to a youth football team.”
To date, over 400 head impacts experienced by the youth football team have been collected and analyzed. "Not only are the impacts generally less severe in youth football when compared to adults, but the frequency of the most severe impacts are substantially lower," Duma said. While most of the impacts collected have been of very low severity; surprisingly, a few impacts are approaching impact levels associated with concussion in adult football players. The goal of this study is to completely quantify and characterize the head impact conditions of youth football, which will provide guidelines to aide manufacturers in designing better helmets for children.
"We have a unique opportunity to quantify the distribution of head impacts experienced by youth players, which no one has ever looked at before," Steven Rowson, research assistant professor of biomedical engineering and creator of the STAR Evaluation System for football helmets, was quoted as saying. Rowson, who also helped design the sensors that are currently in the youth helmets, added, "By knowing these impact distributions, we can develop a safety rating system for youth football helmets that will supplement the National Impact Database. This not only educates consumers on relative helmet safety, but also provides improved design criteria for helmet manufacturers."
This work has implications that are not limited to improved helmets in football, but also has applications towards improved head protection in other sports, as well as advancements in automobile safety designs. Funding for this project is provided by the National Highway Traffic Safety Administration (NHTSA) and the Institute for Critical Technology and Applied Science (ICTAS) at Virginia Tech.
