11 helmets have been assembled by the NFL and NFL Players Association on its common list of equipment approved for 201
By the end of last season, 32 players were wearing helmets that are now prohibited.
Jeff Miller, executive vice president of the NFL for health and safety initiatives, said it is "unusable" to convert
Each equipment manager was instructed to remove all prohibited helmets, which are listed on a poster. on Friday teams. If it is found that a team knows a player who has a helmet banned it, or that it has facilitated the use of one person, it will be subject to control of the league, Miller said on a conference call with reporters.
The NFL and NFLPA have been testing helmets since 2015, but they first agreed last year to prohibit lower performing models. Six people were banned immediately and a further four were approved, including the use of Tomás Brady, Patriots New England's fourth quarter, for another year.
The list of prohibited helmets for 2019 was not upgraded. Of the 11 models tested this spring, nine new ones were on the market, one was significant and one was in the market. another in 2018, according to Dr. Kristy Arbogast, NFLPA engineering consultant.
Six of the new helmets were classified among the top 10 on the 2019 poster . For the third year in a row, VICIS Zero1 helmet came on the list, and the F7 Schutt followed and the SpeedFlex Riddell Precision Diamond.
"One of the most exciting things is how innovation is driving years of innovation," Arbogast said. "You can see when you see the poster that many of the new helmets being introduced into the market are acting as highlights. And so, under the players' perspective, it's great that we are driving the innovation and we are driving better performing products on the field. ”
Approximately 50 percent of players moved to a helmet that was performing better in 2018, according to statistics that d & # 39; issued by the NFL. By Week 17 of the last season, 74 percent of the players used helmet that was in the best category. The NFL will send a list of teams of 32 players who were still wearing underperformance helmets in 2018 to facilitate upgrades.
Arbogast said that the majority of players who opposed the change said they preferred agility, comfort and the appearance of their old helmet. Dr. Jeff Crandall, chairman of the NFL's engineering committee, said some of the models added to this year's list were upgraded versions of these helmets.
"One of the things that prevented some players from moving," Crandall said, "But there is a wide number [approved helmets] capable of being comparable in aesthetics now. We hope that folks will come out of it." "
The helmet test is performed in a laboratory by Biokinetics Inc.. in Canada. According to Crandall, crash test dumps that wear all helmets are subjected to a test rogue that is placed through the influence of eight centers at three speeds each. The tests focus on linear accelerations, rotary accelerations and velocity, he said, and as a result there is a metric performance that "characterizes the ability of helmet to manage forces of influence."
