Speaking of Helmets, NOCSAE Press Release

I was forwarded this NOCSAE press release from a very prominent AT in the NCAA, and although the sender declined to comment, it was his intention to get mine.  I feel it would be good to comment and publish this press release here.  You can find the press release, dated July 3, 2013 HERE.

The purpose of the information provided by NOCSAE was to clear up some perceived and often misunderstandings about the Virgina Tech Helmet Ratings for football helmets.  Like NOCASE, I encourage the research into helmets, the first line of defense against blunt force trauma to the head in collision sports (rodeo included).  However, there are some things that may need explaining.

Now by no means am I taking sides here, I feel Stefan Duma and his cohorts do a tremendous job, as well as the current helmet makers.  I feel that everyone is doing their part to provide Continue reading →

Research From The Now

Virginia Tech and Wake Forest researchers Ray W. Daniel, Steven Rowson, and Stefan M. Duma have published a new research article on impact telemetry on youth football players.  The abstract is as follows;

The head impact exposure for athletes involved in football at the college and high school levels has been well documented; however, the head impact exposure of the youth population involved with football has yet to be investigated, despite its dramatically larger population. The objective of this study was to investigate the head impact exposure in youth football. Impacts were monitored using a custom 12 accelerometer array equipped inside the helmets of seven players aged 7–8 years old during each game and practice for an entire season. A total of 748 impacts were collected from the 7 participating players during the season, with an average of 107 impacts per player. Linear accelerations ranged from 10 to 100 g, and the rotational accelerations ranged from 52 to 7694 rad/s2. The majority of the high level impacts occurred during practices, with 29 of the 38 impacts above 40 g occurring in practices. Although less frequent, youth football can produce high head accelerations in the range of concussion causing impacts measured in adults. In order to minimize these most severe head impacts, youth football practices should be modified to eliminate high impact drills that do not replicate the game situations.

There are some very interesting findings in the abstract alone that need to be noted: Continue reading →
