Using the Head Impact Telemetry System (HITS) made by Simbex exclusive to the Riddell helmet researchers were able to quantify how often and who was sustaining the most force to the head throughout three seasons. The study was performed at Brown University, Dartmouth College and Virginia Tech University; compiling information on 286,000+ hits on 314 players (910+ hits/player). The aim of the study was to identify exposure rates and begin to find ways to limit such exposures if possible.
The lead author on the study was Joseph J. Crisco of Brown University, amongst other faculty positions. This study is set to appear in The Journal of Biomechanics.
