Since the introduction of helmets the incidence of traumatic brain injuries (TBI) in ice hockey has greatly decreased, but the incidence of concussions has essentially remained unchanged. Despite goaltenders in ice hockey being the only players on the ice for the entire game, few have assessed the performance of ice hockey goaltender masks. In ice hockey, goaltenders are exposed to impacts from collisions, falls and projectiles. The objective of this study was to assess the protective capacity of ice hockey goaltender masks for three accident events associated with concussion. A helmeted and unhelmeted medium NOCSAE headform were tested under conditions representing three common accident events in ice hockey. Falls were reconstructed using a monorail drop. A pneumatic linear impactor was used to reconstruct collisions and projectile impacts were reconstructed using a pneumatic puck launcher. Three impact locations and three velocities were selected for each accident event based on video analysis of real world concussive events. Peak resultant linear acceleration, peak resultant rotational acceleration and rotational velocity of the headform were measured. The University College Dublin Brain Trauma Model (UCDBTM) was used to calculate maximum principal strain (MPS) and von Mises stress in the cerebrum. The results demonstrated the importance of assessing the protective capacity of ice hockey goaltenders masks for each accident, as each event created a unique response. A comparison of unhelmeted and helmeted impacts revealed ice hockey goaltender masks are effective at reducing the risk of both concussion and TBI for falls and projectiles, but less so for collisions. Further, the risk of more serious injuries was found to increase for falls and collisions as impact velocity increased. The results highlight the importance of impacting multiple locations when assessing the protective capacity of ice hockey goaltenders masks, as different impact locations result in unique responses. Overall this study demonstrated ice hockey goaltenders masks capacity to reduce the risk of concussion across three accident events.

Cette étude exploratoire vise essentiellement à identifier les principaux facteurs psychologiques des gardiens de but au hockey ayant connu du succès. Plus précisément, cette étude nous a permis d’approfondir le sujet à l’aide d’entrevues individuelles semi-dirigées menées auprès de sept gardiens de but et huit entraîneurs des gardiens de but issus de la Ligue de hockey junior majeur du Québec (LHJMQ). Nous avons ensuite comparé les réponses de ces deux groupes d’experts dans le domaine afin de dresser un portrait précis de l’aspect mental entourant cette position au hockey. Nos résultats démontrent que les mêmes facteurs psychologiques majeurs ressortent du discours des gardiens de but et de celui de leurs entraîneurs. Il a ainsi été possible d’identifier neuf attributs psychologiques prédominants provenant des discours de chacune des parties. Plus précisément, ces neuf facteurs psychologiques reliés à l’atteinte d’une performance athlétique hors pair seraient les traits de personnalité, la résilience, le niveau de confiance, la passion, l’état d’esprit optimal, l’éthique au quotidien, un niveau de concentration optimal, la relativisation des événements et le contrôle des émotions. De manière générale, nos résultats vont dans le même sens que les conclusions tirées des autres études sur les différents aspects mentaux des athlètes de niveau élite. Toutefois, on observe un manque de données scientifiques en ce qui a trait à la psychologie du sport chez les gardiens de but au hockey. Cette étude constitue donc un premier développement dans l’identification des atouts psychologiques influençant la performance des gardiens de but au hockey. / The purpose of this exploratory study was to identify the major mental skills used by successful hockey goaltenders. In-depth semi-structured interviews were conducted with seven goaltenders and eight goaltender coaches from the Quebec Major Hockey League (QMJHL) to be able to get a better knowledge on the topic. Afterwards, we were able to compare the data from the goaltenders and their coaches in order to get a precise picture of the mental characteristics associated with goaltenders in hockey. Our results demonstrate that the same major psychological factors would be identified by the selected athletes and their coaches. It was therefore possible to identify nine psychological attributes from the answers of both parties. More precisely, the nine psychological attributes related to hockey goaltender’s performance are personality traits, resiliency, confidence level, passion, mental readiness, work ethic, optimal concentration level, put into perspective events and emotion control. From a general perspective, our results are consistent with results from other research on the mental aspects of elite athletes. On a more narrow perspective though, we can clearly observe a lack of scientific evidences on the topic of sport psychology related to hockey goaltenders. This study therefore becomes an important first step in the identification of the performance psychological attributes related to the position of goaltending in hockey.
