Laboratory tests developed by biomechanical engineering experts aim to help 国产外流网players make informed equipment choices
NEW YORK, NY鈥擜pril 16, 2018鈥擳he 国产外流网and the 国产外流网Players Association (NFLPA) today announced the results of an annual laboratory study to assess the performance of football helmets worn by 国产外流网players.
Based on the results of this study and the opinions of the biomechanical experts involved, the 国产外流网and NFLPA will prohibit 10 helmet models from being worn by 国产外流网players. In previous seasons, 国产外流网players could choose any helmet as long as the helmet passed current National Operating Committee on Standards for Athletic Equipment (NOCSAE) certification standards. The prohibited helmets perform poorly in laboratory testing, have been discontinued by the manufacturer, or were produced by companies no longer manufacturing football helmets. Six of these helmets are prohibited immediately. The other four may be worn by players who were using them in 2017, but may not be adopted by new players.
The results of the laboratory tests are displayed on a poster and shared with 国产外流网players, club equipment managers, and club medical, training and coaching staffs to help inform equipment choices. Other factors, in addition to the ranking, should be considered by players when choosing a helmet, including fit, comfort, durability, player position and the player鈥檚 medical history.

The goal of the study, as in prior years, was to determine which helmets best reduced head impact severity under laboratory conditions simulating concussion-causing impacts sustained by 国产外流网players during games. The helmet laboratory testing involved 34 helmet models鈥攁 survey of helmets used by 国产外流网teams indicates that at least 98% of players are wearing helmet models that have been tested in this study.
The study continues to measure rotational velocity and acceleration as part of a combined metric to evaluate helmets. The NFL/NFLPA evaluation is the first of its kind to adopt rotational measures in its analysis.
The tests were conducted by an independent helmet testing laboratory, Biokinetics Inc. of Ottawa, Canada. The study formulation, experimental design and data analysis were performed by biomechanical engineering consultants selected and appointed by the 国产外流网and NFLPA. An independent biostatistician, Dr. Timothy McMurry, Assistant Professor of Biomechanics at University of Virginia, Department of Public Health Sciences, was retained to assist in the analysis of the data. The results were then presented to the 国产外流网Chief Medical Officer, Dr. Allen Sills, and to the NFLPA and its Medical Director, Dr. Thom Mayer.
Note: the results of this study should not be extrapolated to collegiate, high school or youth football.
