abstract = {This paper reviews the studies that have been conducted on the performance of the American football helmet in preventing concussion. The review will also guide us to understand what problems still exist and what research directions we should take. Throughout the history of sports, injuries limiting the career life of the athletes have been the leading concern of the sport authorities. These injuries are more extensive in sports in which athletes are in severe contact with each. Mild Traumatic Brain Injury, concussion, widely occurs in American football because of the frequent strokes to players’ heads. Concussion includes several types of neurological dysfunctions such as headache, dizziness, confusion, blurred vision, delayed reaction time and etc. Lots of the studies have focused on understanding the concussion and improving the protective performance of the helmet, so that the dose of the injury in players is reduced. Researches in this area can be classified as two major methods: experimental studies and Finite Element Modeling (FEM) simulations. In experiments, researchers have tried to record head impacts or reconstruct the severe collisions using the game videos in the laboratory conditions. They have used the Hybrid III dummy in order to study the effects of the different impact parameters such as direction, velocity, region of the head being hit and etc. These studies have been done by analyzing the dynamic responses of head including linear acceleration (LA), rotational acceleration (RA), and different head injury criteria like Head Injury Criteria (HIC) and Gadd Severity Index (GSI). Mentioned impact parameters have been also examined using FEM simulations. Researchers have applied the results of experimental tests including linear and rotational acceleration in order to study the brain deformation responses to different types of impacts. In this regards, brain deformation responses like maximum principal strain have been considered and analyzed using the head injury and concussion thresholds. © 2015 The Authors},

abstract = {We conducted a questionnaire survey regarding mouthguards (MGs) in which the subjects were American football players who were users of non-custom-made MGs, and assessed their effectiveness. The questionnaire was administered twice, once before a custom-made MG was prepared and again after it was used. The replies to being asked whether or not they were dissatisfied with wearing the MG showed that the number of players who were dissatisfied decreased after using the custom-made MG. There was no dental trauma with either MG, but non-dental trauma in the oral area and cerebral concussions were both less frequent with the custom-made MG. We think that to improve the frequency of MG use, it is necessary to eliminate the dissatisfaction with wearing them and increase their usefulness. We also think that using MGs with superior fit and wearing comfort that can be worn throughout the entire game will be effective in preventing trauma and cerebral concussions. ABSTRACT FROM AUTHOR},
