La mesure de la performance au hockey sur glace est une problématique majeure à laquelle bon nombre de chercheurs du domaine sportif et d'entraîneurs sont confrontés. L'insatisfaction liée aux techniques actuelles de mesure, principalement les mesures de type indirect, a mené à ce projet de thèse de validation d'un outil de mesure de la performance au hockey sur glace en situation réelle de match. L'adaptation d'une procédure de mesure de la performance " Team Sport Assessment Procedure ", créée par Gréhaigne, Godbout et Bouthier, (1997) pour une situation de hockey sur glace et en situation réelle a été effectuée. Une première étude de validation des variables observées a permis de clarifier les définitions de ces variables et d'expérimenter l'outil de mesure en contrôlant certaines variables externes (temps de jeu et nombre de joueurs impliqués). Des coefficients de corrélation de -0,77 et -0,774 ont été obtenus entre le rang moyen accordé par des experts à 17 joueurs et les scores de performances provenant du TSAP utilisé par les pairs. / Les analyses de variance (ANOVA) effectuées ont démontré des valeurs significatives entre les moyennes des scores de performance des joueurs excellents par rapport aux joueurs faibles, tels que catégorisés sur la base du jugement des experts. La seconde étude a analysé la performance de cent trois (n=103) joueurs de hockey Pee-Wee A de la région de Québec lors des championnats régionaux de hockey de 1997-98. Cette étude a permis de conduire les différentes étapes d'analyse de validité et de fidélité de ce nouvel instrument de mesure. Deux méthodes de comparaison des résultats de score de performance, en fonction d'abord du nombre de points marqués pour chaque joueur lors du championnat et ensuite par rapport aux caractéristiques attribuées par leurs entraîneurs respectifs, ont permis de noter des différences significatives entre les moyennes des groupes observés (ANOVA). Dans les deux cas, les joueurs présumés supérieurs ont obtenu des scores de performance plus élevés; ce double résultat confirme la validité du TSAP. Les résultats de chacune des études permettent de conclure que le "Team Sport Assessment Procedure" permet de mesurer de façon valide et objective la performance en hockey sur glace.

Thesis advisor: Christopher Maxwell / Uncertainty is a key part of any sports game; without it, there is little reason to be interested in the outcome. This thesis attempts to quantify the uncertainty inherent in NHL hockey games by building a real-time win probability model that estimates both teams’ likelihood of winning based on what has happened in the game so far. The model is built using historical data from the 2009-2010 season all the way to the 2016-2017 season. Given the differential and the time left, the model evaluates historical data for that specific game-state and calculates a win probability. The model also uses a multi-regression approach to incorporate pre-game Vegas odds as a way to factor the strength of both teams; to my knowledge, this is the first publicly available hockey win probability model to do so. Finally, the model also factors in elements unique to the sport of hockey, like power plays and shootout periods. / Thesis (BA) — Boston College, 2018. / Submitted to: Boston College.

This study describes the biomechanics of the foot during an ice hockey tight turn. Pressure data were collected with flexible piezo-resistive sensors from 15 anatomical points on both left and right feet. Participants included 8 elite (86.82 Kg +/- 6.48Kg, 179.69 cm +/- 6.74cm) and 8 recreational level (82.10Kg, +/- 7.49Kg, 175.63cm +/- 6.37cm) hockey players, with the elite players being members of the McGill varsity team and the recreational players participating in recreational organized hockey of lower caliber. The data from three to four turns for both left and right tight turns were collected and normalized, with statistical measures taken for blade contact/turn initiation, peak pressure and peak pressure at push off. Two way ANOVAs showed numerous areas of statistical significance (p ≤ 0.05) between the elite and recreational participants. The tracking of center of pressure was also investigated leading to some speculations of advanced techniques for the successful execution of a tight turn. / Keywords.

The purpose of this research was to build upon, and extend, the sport diversity research. Specifically, Study 1 adopted a compositional approach to examine the effects of ethnicity, age, and team tenure on a team process (team assists), and their indirect effects on overall team performance (team points) through that team process. Hierarchical regression analyses, after controlling for team ability, indicated that the block of diversity variables accounted for 6.5% (p < .05) of the variance in team assists. Further results indicated that ethnic diversity was significantly, and negatively, related to team assists, while age and team tenure diversity were not related to team assists. In turn, team assists accounted for 22% (p < .001) of the variance in team points, above and beyond team ability. Team assists were significantly, and positively, related to overall team performance. Results suggest that team diversity does impact team processes and, indirectly, team performance. Study 2 adopted a relational approach to examine how being similar, or dissimilar, influences the dyadic relationship between the goal scorer and assistor. The MANOVA analyses were significant for ethnicity, Wilks’ Λ = .976 (p < .001), age group, Wilks’ Λ = .952 (p < .001), and team tenure group, Wilks’ Λ = .896 (p < .001), indicating that there were differences between those goal scorers receiving assists from the various subgroups within each of these three categories. In general, results support the similarity-attraction paradigm, in that, a player is likely to assist a teammate who is similar to himself more so than he is to assist a player who is different, with regards to these three demographic characteristics. Results have practical implications for coaches and managers, while also contributing to the theoretical body of literature for sport and diversity research. This research examined National Hockey League teams and players during a three year period (2001-2004). English Canadians made up 42.5% of the players in the league, followed by Europeans (33%), Americans (15.7%), and French Canadians (8.8%). The average age of players in the league was 27.7 years of age, while the average team tenure was 3.7 years.
