Le hockey sur glace est un sport majeur et populaire en Amérique du Nord. La LNH (Ligue Nationale de Hockey) est considérée comme la ligue la plus prestigieuse du monde et regroupe une trentaine d’équipes avec des millions de supporters. Les gros enjeux sportifs et financiers qui pèsent sur les équipes de hockey poussent les entraîneurs à utiliser des méthodes et des équipements qui préparent et développent aux mieux les capacités de leurs joueurs. Parmi les outils à leur disposition on s’intéresse tout particulièrement dans cette étude au lance rondelle, un dispositif mécanique reproduisant le tir de rondelle d’un joueur. Le but de ce projet de maîtrise repose donc sur le développement d’un lance rondelle robotisé totalement automatique pour l’entrainement des gardiens de hockey. À travers une présentation chronologique on expose la démarche de conception entreprise pour aboutir au lance rondelle robotisé en commençant par présenter le prototype initial utilisé comme base auquel on apporte deux modifications majeures, respectivement un nouveau système de positionnement laser et une interface de commande et de contrôle développée en python et implémentée sur un Raspberry Pi. On y développe aussi les équations utilisées pour calculer la position du lance rondelle dans l’espace et le modèle balistique employé pour évaluer la trajectoire de la rondelle. Pour finir on mesure et on quantifie la précision et la répétabilité des tirs et du positionnement de la machine.

This study investigated the within-group differences in ice-time and experience with the team in task cohesion perceptions of college hockey players and their relationship with team performance success. One hundred and seventy-one male hockey players between the age of seventeen and twenty-two years, representing ten teams, answered the two task portions of the Group Environment Questionnaire, as well as a question concerning their feelings regarding the amount of ice-time received during games. The data was analysed using a 3 x 2 ANOVA for success by ice-time and success by experience with the team for each of the two measures of task cohesion. The results showed the more successful teams to be most cohesive, but significant (p $<$.05) within-group differences were only found among the veterans and rookies of the least successful teams. It was concluded that within-group differences in cohesion exist in teams of low levels of success, but that highly and moderately successful teams do not experience the phenomenon. Teams success may be the determinant of the existence of within-group differences in task cohesion.

The purpose of this study was to examine the effect of puck mass on shot velocity of female ice hockey players. The contributions of upper body strength and skill level to shot velocity were also examined. Female varsity and recreational players (n = 29, age = 21.3 yr) performed shooting tests on ice. The participants shot 20 light weight (5 oz) and 20 regulation (6 oz) pucks, using 4 different types of shots (standing wrist shot, standing slap shot, skating wrist shot, skating slap shot). The on-ice tests were followed-by 3 musculoskeletal tests; predicted 1 repetition maximum (1 RM) bench press, hand grip, and sit-ups. The light weight puck resulted in a significantly higher velocity compared to the regular weight puck (P < 0.05). The average shooting velocity was 1.4 km/h higher with the light weight puck compared to the regular puck (69.8 vs. 68.4 km/h) based on overall means (4 shots x 2 pucks). Positive correlations were found between overall shot velocity and musculoskeletal tests of hand grip (r = 0.81), predicted 1 RM bench press (r = 0.77), and sit-ups (r = 0.48). These results are discussed in relation to literature on the women's ice hockey and physiology.

This study examined the relationship between the physical fitness of National Hockey League (NHL) entry draft players and performance in the NHL. Physiological profiles were compared by level (NHL vs non-NHL) and position (forwards vs defense). The fitness level was determined by an assessment of body composition, anaerobic fitness, strength, power, muscular endurance, flexibility, and aerobic fitness. Subjects were 422 male hockey players, consisting of NHL entry draft (n = 310), minor league professional (n = 59) and NHL professional (n = 53) players. Results revealed that when drafted, physiological profiles of players who reach the NHL were significantly different from non-NHL players. Players that eventually made the NHL tended to be heavier and had higher peak power (W), mean power (W), VO2max (L/min), grip strength and leg power. The fitness variables in the test battery had low predictive power to identify players who played in the NHL. Physiological profiles of forwards were significantly different from defense. Defense were taller, heavier, and fatter than forwards. Defense had higher peak power (W), grip strength and leg power compared to forwards. The forwards were higher in VO2max when expressed relative to body weight. NHL entry draft players were lower in upper body strength than minor league professionals and NHL players.
