A total of 4,543 impacts were analyzed with an average impact of 20g and a median of 71 impacts for each player per game. The data showed no difference in impacts between defenseman and forwards, but did find that hits were significantly greater during games than in practice. Perhaps most surprising was the data regarding impact location. Players were at least three times as likely to receive an impact over 80g to the top of the head than to the front, back, left or right. Bad form in developing players might be the cause of this unexpected trend. While defining an exact concussion threshold will likely never occur, previous research in football has suggested a greater likelihood of concussions at impacts above this level. Interestingly, of the 41 impacts above 80g detected, only one resulted in a concussion.
