This year, all models prohibited in 2018 are displayed on the 2019 poster, including those not tested but produced by companies no longer manufacturing football helmets. *A subset of prohibited models were displayed on the 2018 poster. Note: The results of this study should not be extrapolated beyond the NFL, including to collegiate, high school or youth football. Timothy McMurry, Assistant Professor of Biomechanics at the University of Virginia’s Department of Public Health Sciences, was retained to help with analysis of the data. Kristy Arbogast, Co-Scientific Director and Director of Engineering for the Center for Injury Research and Prevention and Chair of Pediatrics at Children’s Hospital of Philadelphia. Barry Myers, Professor of Biomedical Engineering at Duke University, and Dr. The analysis was done in conjunction with two NFLPA-appointed consultants, Dr. James Funk, Principal Engineering Consultant and Co-Founder of Biocore. Ann Good, Senior Mechanical Engineer for Biocore and Dr. Jeff Crandall, Professor of Engineering and Applied Science and Director of the Center for Applied Biomechanics at the University of Virginia Dr. The experimental design and data analysis were performed by NFL-appointed consultants including Dr. Allen Sills and by NFLPA Medical Director Dr. Results were reviewed by NFL Chief Medical Officer Dr. An independent biostatistician was retained to assist in the analysis of the data. The tests were conducted by an independent helmet testing laboratory, Biokinetics Inc. As of the final week of the 2018 season, only 32 players (less than 2% of total players) remained in one of the prohibited helmets. Analysis of on-field game concussions for the 2015-2018 seasons showed that players wearing green helmets had a lower rate of reported concussions than those wearing yellow or red helmets. The percentage of players wearing helmets in the top-performing (green) category increased by one-third to 74% of all players by the end of the 2018 season. All helmets tested met the current National Operating Committee on Standards for Athletic Equipment (NOCSAE) certification standards to protect players against severe traumatic skull and brain injuries.Īfter issuing last year’s poster, approximately 50% of NFL players upgraded to a better-performing helmet. Six of the 11 helmets tested this year are among the top-10 rated models, signaling that industry-driven improvements in design, engineering and technology are yielding better results for reducing head impact severity in the tested conditions. Helmets that are listed in grey text on the poster were worn by fewer than 1% of all players. Ninety-nine percent of NFL players wear helmet models tested in this study. The 2019 helmet poster includes the laboratory testing results for 34 helmet models, including the 11 helmets tested this year. None of the 11 helmets tested this year were added to the list of prohibited helmets however those on the prohibited list* in 2018 remain as such and no player will be grandfathered into being able to wear a prohibited helmet this season. On the 2019 poster, the top-performing helmets in the laboratory testing are shown in a gradient of green, with darker green helmets performing better than lighter green helmets, and helmets in yellow performing worse than the green helmets. The tests, designed jointly by NFL and NFLPA-appointed biomechanical engineers, simulate a subset of concussion-causing impacts sustained by NFL players during games to determine which helmets best reduced head impact severity in those conditions.The study continues to measure rotational velocity and acceleration as part of a combined metric to evaluate helmets. The results of the tests are displayed on this poster and shared with NFL players in addition to club medical, training, coaching and equipment staffs to help inform equipment choices. NEW YORK – Ap– The NFL and NFL Players Association today released the results of their annual laboratory study to assess the performance of helmets worn by NFL players. NFL, NFLPA RELEASE 2019 HELMET LABORATORY TESTING PERFORMANCE RESULTSġ1 helmet models tested this year, six are top-10 rated 74 percent of players wore top-performing helmets by the end of the 2018 season
