Abstract
Little is known regarding the implications of motor asymmetries for skilled performers in dynamic, time-constrained, team-based activities such as ice hockey. Two studies were conducted to examine laterality differences in ice hockey. Study one investigated laterality distributions across three leagues of increasing league calibre. Among skating players, skill level was related to changes in laterality patterns based on position, while a significant increase in the proportion of left catching goaltenders was found across the levels of competition. Study two examined laterality differences through a 90-year retrospective analysis of player performance measures within an evolving system. Regression analysis indicated right shot preferences were associated with scoring more goals, while left shot preferences were related to assisting more goals. Among goaltenders, right catching preferences were associated with an increased save percentage compared to left-catching goaltenders. Results suggest ice hockey supports models of skilled perception, and provides new information in the area of laterality and strategic frequency-dependent effects in ice hockey.
